I understand what you said, Bob, that 6210 SHOULD have been heard in the area from Howland for many hundreds of miles on south but that wasn't the case at Lae. Her first transmission that Lae reported as hearing was 4 hours and 18 minutes after take off. Of course it may be that was the first radio call she made but my understanding was that she was to report hourly at about 18 minutes past the hour. She was then heard one hour later and then two hours later but not after that. I don't know what happened to the 16:18Z radio call or if it was even made. The 17:18Z call was still on 6210 is my understanding. Is that correct, Ric? She may have soon switched to 3105, her night time freq and that seemed to have a short range as gaged by her calls to Itasca. Then when she switched back to 6210 she was in the same range from Howland to Niku as she was out of Lae. It seems to me to be consistant she wasn't heard in either case. Bob, do I have this right or am I confused? Alan ************************************************************************ From Ric Bob has not run the SNRs for the transmissions heard in Lae. Chater says: "Arrangements had been made between the plane and Lae station to call at 18 minutes past each hour and arrangements made to pass any late weather information, but local interference prevented signals from the plane being intelligible until 2.18 p.m." The plane took off at 10:00 a.m. Sounds to me like unintelligible voice may have been heard at one or more of the scheduled hourly times (10:18, 11:18, 12:18, 13:18). =============================================================== Date: Mon, 2 Dec 2002 09:34:58 EST From: Carol Dow Subject: Re: Nauticos on TV Tonight- Israeli Submarine Dakar Jon, Nauticos is following the Elgen Long story.

Especially, one where it was later found transmissions were clearly not made. I'm wondering if it is a common phenomenon, perhaps caused by people trying so hard to listen for anything (and in the case of high-profile flights perhaps caused by hoaxes). If not, it lends even more validity to AE's post loss messages. Melanie ************************************************************************ From Ric That is a VERY interesting question - and I don't know the answer. I can think of a couple of disappearances we could check. - In December 1934, Charles Ulm and two companions took off from Oakland for Hawaii in a twin-engine Airspeed Envoy named "Stella Australus" on the first leg of a planned trans-pacific flight to Australia. They disappeared and were never found. The aircraft had a radio. It would be interesting to check the newspaper coverage of that disappearance to see if messages were reported. - In November 1935, Sir Charles Kingsford-Smith and copilot/mechanic Tommy Pethybridge disappeared in the Lockheed Altair "Lady Southern Cross" in the Bay of Bengal somewhere south of Rangoon. In May 1937, the starboard undercarriage leg with wheel and tire attached were picked up by a Burmese fisherman on the shore of an island off the south coast of Burma. Smithy had a radio. I don't know if post-loss signals were reported but the discovery of wreckage argues against any being sent. There is a recent biography entitled "Smithy" by Ian Mackersey that deals extensively with the last flight. =============================================================== Date: Mon, 2 Dec 2002 10:21:23 EST From: Daryll Subject: PTT vs Key Mike Everette wrote: >Bill Shea wrote: >>I always thought that an 'unmodulated carrier' was a fancy term for a tone. > >An unmodulated carrier is a signal without modulation.

QUESTION : Mike, how could the Itasca record long dashes at 08:00-03 if they didn't have a key in the airplane? You said that a keyed PTT switch would produce a carrier and I assume the ambient background noise (if any) heard on the phone. The Itasca log indicates whistling when the was whistling or other noise heard. If the PTT was depressed you should hear the cockpit engine noise correct? Was the Itasca hearing a keyed dash from a key or the depressed PTT switch?

From there it goes to Pat for layout and then to the printer. =============================================================== Date: Mon, 2 Dec 2002 10:39:02 EST From: Gary LaPook Subject: Re: Antenna A big problem for me with the reported reception of post 2013 Z messages has to do with the difficulty of tuning the radios of that era to a particular frequency either 3105 kc or 6210 kc. The young people on the list who have been raised with digital tuning on every radio do not appreciate the difficulty of using tuning knobs and trying to tune in a station when the markings on the "tuning dial" are inexact. I would like to know how the people who claimed to hear AE on one of these two frequencies could be sure that they were actually tuned to her transmitting frequencies. A simple example. Using an old AM radio with a tuning dial try to tune a particular broadcast station. If, say you wanted to listen to Rush at 10:00am on KFI in Los Angeles you tune to approximately "6" or "600" on the am dial and listen for a broadcast. It may or may not be KFI and you can't be sure until you hear a station identification. Even if you know that Rush is on KFI at 640 kc and you hear his voice you still can't be sure that you have tuned to 640 because Rush is also broadcast on KOGO from San Diego on 600 kc. and "6" or "600" on the dial could represent either station because of the inexact nature of tuning dials. That was an easy example because both of these stations broadcast continuously so you can tune around and wait for the station identification. It is not so easy to find a station that transmits sporadically and for only short periods. In this case you can't just tune around in hopes of finding such a transmission since it is highly unlikely that you would happen to be tuned to the exact right spot on the dial at the exact time that AE made a short transmission. Even if the dial said "31" it is just as likely to be set to 3035 or 3096 or 3156 (even 3309) etc. as to be set to 3105 kc. It is very likely that many of the transmissions received and reported to be coming in on 3105 were actually received on some other nearby frequency. And what are the chances that "Betty" just happened to be tuning to the 5th harmonic of AE's transmitter's frequency at exactly the same instant that AE makes a short sporadic transmission. It would be like hitting a bullet with another bullet. ( I know, that can happen. I have seen a photo of a Jap and an American artillery projectile fused together but I have only seen one such photo.) So, what if you got lucky and could be sure that you were tuned to 3105 because you heard, for instance, a Coast Guard station identify and state that it was transmitting on 3105. Can you then just leave your radio set where it is so that is will remain on that same frequency? Unfortunately, no. Radios are tuned by adjusting the output of a "variable frequency oscillator" (VFO) which is then fed to other stages of the radio. The tuning knob and tuning dial are both connected to the VFO. Turning the tuning knob changes the output frequency of the VFO and also turns the tuning dial. Any change in the frequency of the output from the VFO changes the frequency that the radio receives. VFOs lacked "stability" in that they would drift over time mainly due to changes in the temperatures of the various components of the VFO and sometimes they would change just from the presence of your hand on the tuning knob. So even if you started out accurately tuned to 3105, wait awhile and you will be receiving a different frequency without any change on the tuning dial. This is the reason for crystal control of communications radios. Certain kinds of crystals can be ground to a particular thickness and the crystal will oscillate in a set, fixed frequency. The crystal is manufactured for a particular frequency, say 3105 kc, and it will always oscillate at that frequency and can be used to control the tuning of the transmitter and receiver. Only with crystals cut for the right frequency could you be sure that you were transmitting and receiving on a fixed frequency. It is highly unlikely that any casual listener or ham would have had crystals for 3105 or 6210 kc and so can not be sure that they were receiving on those frequencies. Modern radios have computer controlled "phase locked loops" (which also uses a crystal for a reference frequency) with digital readout so you can set them to a fixed frequency and they will be accurate and stay on that frequency which is, obviously, a great improvement. (Speaking of KFI, it must have also been a communication station in 1937 because GP Putnam stayed at the station so as to communicate during the flight and search. Anybody with information about this?) gl ************************************************************************** From Ric As far as I know, everything you say is true. All of the reported amateur receptions, if legitimate at all, were apparently on harmonics of 3105 and 6210 and all were accidental. None of the amateurs claimed to have been intentionally listening for Earhart. On the other hand, if transmissions from the airplane could be heard on harmonics and thousands and thousands, if not millions, of people in the U.S. regularly surfed their shortwave dial for something interesting, it would be surprising if a few did not stumble upon a transmission from the plane. However, as I've said before, the vast majority of suspected post-loss transmissions were reported by professional radio operators in or near the search area. Their reports include discussions of the problems you describe about verifying frequencies.

Happy Thanksgiving. Talked with Bruce Smith, the avionics man, in fact I just got off the phone with him. Bruce says the following after reading all the emails: 1. Marker beacon antennas were not approved for general aviation until 1938. So Earhart's Electra did not have a marker beacon antenna on the belly. 2. The belly antenna that was installed on the Electra had to be a range antenna and 18ft. is the right length. It is also the right length for a sense antenna and Earhart could have unplugged the range antenna in flight and switched it over to a sense antenna. All of this would be dependent on the capabilities of the avionics. However, it should be noted the two types of antennas are interchangeable and they are of the same length (sense and range). 3. The sense antenna and the range antenna have nothing to do with voice or Morse code communications. 4. Before the wreck in Hawaii there was evidently two antennas on the belly of the airplane. One of them must have been a sense antenna and the other one a range antenna. 5. The loss of the sense antenna off the belly of the airplane would have lost the 180 degree ambiguity feature of a fixed loop radio compass DF. Smith is saying there was probably an indicator on Earhart's panel that indicated left and right plus or minus 5 degrees on the null. The sense antenna operated in the range of 200 kilohertz to 500 kilohertz and was probably a dial operated radio system. So, the above is confirmed. End of story except nothing really new except the marker beacon antenna is deleted. The DF didn't work (which we already knew), but it would be especially true if the sense antenna was missing. Smith also says the sense antenna would also have provided a continuous signal if it was there.

There was lots of aviation activity around New Guinea in support of gold mining at that time. If 6210 was a standard frequency for aviation use in the area there might have been a lot of traffic. The other possibility is local atmospheric interference. I know from personal experience flying in New Guinea that by noontime on a typical day there are big nasty buildups over the Owen Stanley mountains just in back of Lae. =============================================================== Date: Tue, 3 Dec 2002 09:30:24 EST From: Bob Brandenburg Subject: Re: Antenna Alan Caldwell wrote: > > Table A-1 shows that Earhart's signal on 6210 would have been readablefrom > > anywhere between Howland Island and Gardner Island until 2130Z, up to 250 > > miles from Howland until 2230Z, and up to 200 miles after 2330Z. > > Bob, is that true of the flight out of Lae also? No, because the path loss changed differently over time in the two cases. The path loss in skywave propagation is the sum of two components: free-space loss and absorption loss. Free space loss is due to geometric spreading of the wave front and varies with distance. Absorption loss occurs in the D layer, which is the lowest ionosphere layer and lies between the approximate limits of 75 and 90 kilometers above the earth's surface. The absorption in this layer is due to ionization resulting from solar radiation, which varies with the sun's angular elevation above the horizon. The D layer exists only during daytime and disappears rapidly after sunset. The layer does not reflect signals at frequencies above 1 MHz, but it does absorb energy at all frequencies. Skywave signals pass through the D layer enroute to their reflection points higher in the ionosphere, and again on the way down, incurring absorption loss both ways. In the LOP case, free space loss increased with elapsed time as the Electra flew away from Howland. And, since the signals of interest occurred during the first few hours after sunrise, the D layer absorption was increasing with time as the sun's elevation angle increased. The combined result result was a steadily increasing composite path loss, which accounts for the time-varying communication distance limits. On the flight out of Lae, free space loss increased with elapsed time as the Electra's distance increased. But the signals of interest occurred in the late afternoon when D layer absorption was decreasing, the opposite of what happened in the LOP case. At 0418Z, the time of AE's first report, the sun's elevation angle was decreasing everywhere along the path to Lae, where sunset would occur at 0808Z. The decreasing D layer absorption loss outweighed the increasing spreading loss component, resulting in a net decrease of path loss with time, as shown by the Lae operator's observation that Earhart's signal strength was increasing over time.

Brent ************************************************************************ From Ric Survival on Niku depends on two factors: A. The availability of sufficient drinking water. B. Not getting hurt or sick. A. We don't know how much water they carried with them but even a liberal guess leaves them needing more water within a day or so. The only way they ad to get drinkable water was to catch rainwater. To catch rainwater it has to rain and you have to have some way to catch it. We have no way of knowing how often it rained during the days, weeks, and months immediately following the disappearance except to note that when Maude and Bevington visited the island in October the vegetation was lush. Soon thereafter, however, the region suffered one of the worst droughts on record and by the time the New Zealand survey party arrived in Dec. 1938 the island vegetation was shriveled and dry. The drought broke that next spring and by April of 1939 the vegetation was pretty much back to normal. How long could AE and/or FN have been able to collect enough water to survive? A reasonable guess would be until well inot the autumn of 1937. After that it seems like it would be pretty iffy. B. It's not easy to not get hurt or sick on Niku, especially if you have to be out on the reef (where it's easiest to catch fish). The reef is very slippery in places and a fall can mean a cut or scrape on the coral that, unless immediately treated, is guaranteed to become infected. In fact, and nick or scrape can quickly become a problem. We carry alcohol swabs with us and get fresh water showers every evening, and we still run into problems. I don't think we've ever run an expedition out there where we didn't have somebody lose at least a day to infection or illness. In addition to the danger of infection, some of the fish in the area are toxic if eaten at a particular time of the year. The Blacktip sharks on the reef and in the lagoon are really not much of a concern unless you're already bleeding (ask me how I know) but if the occasional Tiger or Pelagic Whitetip stops by, all bets are off and it's a good idea to stay the hell out of the water. It seems like a pretty good bet that the castaway died of either dehydration (thirst) or illness. The skull seems to have been found in April 1940 but remains deteriorate so rapidly in that environment that we really can't put a not-later-than date of death on the castaway earlier than about May of that year. I'm afraid I can't give you a very precise answer. If the castaway found in 1940 was Earhart then she survived for somewhere between several weeks to almost three years.

It appears that she switched to 3105 at sunset, as she had said she would before leaving Lae. Sunset was at 0721Z at the position given in her 0718Z report. We don't know where she as at 0718Z since we don't know whether the position report was contemporaneous. But I suspect her report was sent close to sunset at her then current position. If she followed her plan, she switched to 3105 right after her 0718Z transmission. > Then when she switched back to 6210 she was in the same range from Howland to > Niku as she was out of Lae.

Later Bendix DF receivers used exactly such a system. The manual loop was coupled through a tach shaft to the big "Radio Compass" indicator dial. There was a "Left-Right" indicator, consisting of a zero-center meter, on the instrument panel. The "left-right" meter was driven by circuitry in the receiver.

Earhart refers to it specifically in describing the panel in the Karachi interview. An August 1937 article in Aero Digest shows a "remote control head" used with the Bendix MN-1, MN-3, MN-5, and MN-7 Direction Finders. It's a box with a compass rose and a two-sided needle. Above the top of the compass rose is an index line and what appears to be a rotatable setting marked in degrees. At the top left of the box there is what appears to be a toggle switch labeled "Switch" and at top right there is another one labeled "Light". At bottom left is a crank labled "Azimuth" and at bottom right is another crank labeled "Tuning". All four systems are "almost identical except for the method of controlling loop rotation". "Bendix D-Fs are designed to operate in conjunction with the Bendix Type RA1 receiver but will also give accurate and dependable bearings when used with any standard radio receiver covering the desired frequency range." Earhart's seems to have been an MN-5 in which the loop was manually controlled and could be "mounted at a point not directly over the coupling unit with the rotation controls on the loop shaft at the cabin roof." "Each D-F consists of a loop unit for reception of signals, a coupling unit for comparing characteristics of the signal received by the loop to those received by a fixed antenna, and the necessary cables and connections. The electrical coupling unit automatically resolves the 180 degree ambiguity of the loop, permitting unilateral bearings." We have photos of the loop and coupling unit being installed in March just prior to the first World Flight attempt. At that time the airplane still had two belly antennas - the original starboard antenna that came with the airplane and the port antenna that appeared at the same time the Hooven Radio Compass was installed. It seems reasonable to assume that the port antenna was a sense antenna for the Hooven unit and probably retained that function when the Hooven automatic system was replaced with the "old fashioned" manual loop. The ability to use the Western Electric receiver via the MN-5 system allowed the removal of the separte receiver required by the Hooven system and thus save the 30 pounds Hooven refers to in his paper. The mystery comes when the airplane comes out of the repair shop following the Luke Field wreck with only one (the orginal starboard) belly antenna. Hypothesis: Maybe the starboard belly antenna delivered with the airplane was a "range" antenna intended for use with the low frequency radio range navigation facilities then in use around the United States. For the second WF attempt maybe it was decided that little or no "range" flying was contemplated and the starboard belly antenna became the sense antenna for the MN-5 system.

Members of the Forum may be interested in listening to this interview, which describes a project that's trying to cope with many of the same problems we are. *************************************** Friends and colleagues: Archaeologists today sometimes apply their craft to exploring very recent historical events. An unusual example of this is the archaeological testing at the claimed 1947 crash site of an extraterrestrial spacecraft near Roswell, New Mexico. In the latest Audio Interview featured by our public education website, The Archaeology Channel (www.archaeologychannel.org), we asked University of New Mexico archaeologist Dr. Bill Doleman, who directed the Roswell fieldwork, to share with us his experience in "extraterrestrial archaeology." On November 22, 2002, the SCI FI Channel aired a two-hour documentary that depicted archaeologists investigating the purported crash site. Archaeological excavations under Dr. Doleman were carried out under contract with the SCI FI Channel. Although in this case the client (the SCI FI Channel) and the subject (extraterrestrial visitors) are both unusual, archaeology under contract is by far the most common form of archaeological work in the United States and in many parts of the world today. The shift in emphasis over the past three decades from purely research-oriented to contract archaeology has greatly expanded financial support for archaeological work, but has also highlighted issues about information-sharing and ethical standards. In this interview, we explore with Bill Doleman how this project came about, what his team found and how it has been portrayed, and how it illustrates the practice of contract archaeology today. This and other programs are available on TAC for your use and enjoyment.

I have been studying your notebook for some time and feel very sure now that it really was Amelia Earhart you heard and not some hoax or misunderstanding. You are no doubt aware that no less than three other radio listeners also gathered that Fred Noonan was injured from the transmissions they picked up. It is obviously a long time ago now but I wonder if you can recall something. Can you be SURE that Fred was behaving erratically because he was delirious rather than because he was in pain or even perhaps because he was angry about his injuries? Did you really get the impression that he was behaving in a manner that could ONLY have been because he was delirious? The reason I ask is that his condition is very relevant to explaining exactly what took place. From the many other radio messages, one can determine that FN was transmitting quite a large amount of the time in the early days after their landing. It does seem unlikely that AE would have allowed him to transmit over a period of many hours if he was deranged then (although it is quite possible she was unable to stop him). Latterly the transmissions all seem to have been from AE and this would then place the transmission you received as possibly the last of the lot, at a time when he had succumbed perhaps to a fever as a result of infection or even a haemorrhage. If FN was deranged from the time of their landing, on the other hand, it would perhaps explain why they were unable to give an accurate idea of their position. I think you can be sure that your notes now get the attention they always deserved and it is indeed fortunate that you had the presence of mind to record in writing, what many might have merely listened to.

Back in May of 1968 I was the designated Trust Territory of the Pacific Islands Information Office employee sent to Palau to cover a South Pacific Commission conference on fisheries issues. In the end, the conference was cancelled because the French government, which had volunteered to bring in the bulk of the participants on a French military airplane, was suddenly distracted by more urgent events at home. As I recall, a major topic of the conference was to be the phenomenon of toxic fish -- a condition that was perceived (at that time, at least) to be worsening, so that fish that had once been safe to eat at any time of the year were becoming toxic, and the toxic periods for other fish were expanding. Supposedly, the condition was spreading westward, so that folks in the Marshalls were beginning to find some fish poisonous which they had traditionally eaten but which the Hawaiians, to the east, couldn't remember ever being able to eat. The point of having this conference in Palau was that as the westernmost island group (just about) everything was still edible there. In fact, the conference organizers went ahead with an abbreviated version of the big seafood feast that had been planned to boggle the minds of the fisheries people from all the eastern island groups where they would be invited to taste fish that would be deadly poison in their home islands. Does anyone know if this phenomenon of toxicity spreading westward actually continued? Was the concept ever proven or disproven? The only relevance to the Forum would be that if this was truly happening, some fish species that no one would dare eat today in the Phoneix Islands could have been safe to eat in 1937. -- Marjorie Smith *********************************************************************** From Ric We do have good information that toxicity was a problem even back then.

Since then we have continued to work with Betty, attempting to verify as much as we can about what she heard and how she heard it. She has been unfailinging cooperative and consistent in her recollections. The more our hypothesis about what happened has developed based on other evidence, the better her notebook fits the evolving scenario. Working with Betty's notebook is dangerous. If you get beyond the analysis of words and phrases and allow yourself to accept that you're eavesdropping on terrified people who are doomed to die there is an intimacy there that is almost obscene.

Mike H. *********************************************************************** From Ric Good question. I can think of movies that came much later ("Island In the Sky" for example) but I can't think of a 1930s film where a plane goes down and sends calls for help. What is really interesting is to track how and when the idea that Earhart was somewhere calling for help got started. Let's follow the chronology as revealed in the official messages and the ITASCA's radio log. July 2nd 20:13Z (08:43 a.m. aboard ITASCA) Last inflight message heard. "WE ARE ON THE LINE 157 337.... etc." 21:45Z (10:15 a.m. aboard ITASCA) ITASCA sends out first message to Coast Guard San Francisco Division and others indicating that Earhart is overdue. "...ESTIMATE 1200 FOR MAXIMUM TIME ALOFT AND IF NON ARRIVAL BY THAT TIME WILL COMMENCE SEARCH NORTHWEST QUADRANT FROM HOWLAND AS MOST PROBABLE AREA. SEA SMOOTH, VISIBILITY NINE, CEILING UNLIMITED. UNDERSTAND SHE WILL FLOAT FOR LIMITED TIME." In San Francisco it is 1:45 p.m. and we must presume that the news immediately went out that Earhart was overdue at Howland. Hoaxes are theoretically possible from this time on. 21:48Z (10:18 a. m. aboard ITASCA) ITASCA sends message to Coast Guard Hawaiian Section. "SUGGEST NAVY CONTACT FOR SEA PLANE SEARCH. SIXTEEN HUNDRED GALLONS AVIATIONS GASOLINE NOW ON HOWLAND AND NINETY FIVE GALLONS LUBRICATING OIL." 22:10Z (10:40 a.m. aboard ITASCA) Deciding not to wait until 12:00, ITASCA departs Howland to begin searching. 00:31Z (1:01 p.m. aboard ITASCA) Hawaiian Section tells ITASCA, "ADVISE BY DISPATCH FULL DETAILS CONCERNING EARHART PLANE SUCH AS POSITION REPORTS BEARINGS AND ALL INFORMATION EARHART FLIGHT THAT WILL BE OF VALUE TO NAVAL SEARCH IF PLANE DESPATCHED FROM HERE. RECOMMEND YOU BROADCAST DATA TO ALL SHIPS TO BE ON LOOKOUT. 00:45Z (1:15 p.m. aboard ITASCA) ITASCA advises Hawaiian Section, "EARHART UNREPORTED HOWLAND AT 1200. BELIEVE DOWN SHORTLY AFTER 0915. AM SEARCHING PROBABLE AREA AND WILL CONTINUE. Why 9:15? The logic is hard to fathom. Earhart was supposed to transmit at quarter to and quarter past each hour. At about 7:45 some thought she said "half hour fuel left". At 8:00 she said she couldn't get a radio bearing. At her next scheduled time at 8:15 they didn't hear anything so they assumed that she had gone down so they called the guys on Howland back to the ship and started getting ready to begin a search. Then at 8:43 she surprised everybody and said she was "on the line 157 337..." and that she was switching frequencies to 6210. At her next scheduled time of 9:15 they heard nothing (they were, themselves, transmitting at that time and blocking any incoming signals). Somehow out of all this they decided that she was "down shortly after 0915". 01:03Z (1:33 p.m. aboard ITASCA) ITASCA sends message to "ALL SHIPS:" "AMELIA EARHART PLANE ENROUTE HOWLAND ISLAND FROM LAE NEW GUINEA UNREPORTED SINCE 2045 GCT JULY 2 AND APPARENTLY DOWN AT SEA POSITION UNKNOWN. ITASCA SEARCHING PROBABLE NORTHWEST SECTOR OFF HOWLAND ISLAND. REQUEST SHIPS AND STATIONS LISTENON 500 KCS FOR ANY SIGNALS FROM PLANE COMMANDING OFFICER, U. S. COAST GUARD CUTTER ITASCA" This is the first suggestion that post-loss signals might be possible but the only frequency mentioned is 500 Kcs. It is 5:03 p.m. on the West Coast of the United States. Evening editions of major California papers carry headlines that Earhart is missing but make no mention of post-loss signals because none have yet been heard. 02:00Z (2:30 p.m. aboard ITSACA) It is 3:30 p.m. in Hawaii. The Pan American Airways DF station at Mokapu receives word that Earhart is down and begins a constant radio watch on 3105 and 6210. 02:45Z (3:15 p.m. aboard ITASCA) The U.S. Navy Hydrographic Office radio station in San Francsico sends to "ALL SHIPS, ALL STATIONS": US COASTGUARD SHIP ITASCA BELIEVES MISS AMELIA EARHART DOWN BETWEEN THREE THREE SEVEN AND NINE ZERO DEGREES FROM HOWLAND ISLAND AND WITHIN ONE HUNDRED MILES OF ISLAND. POSSIBILITY PLANE MAY USE RADIO ON EITHER 3105 6210 OR 500 KCS VOICE. REQUEST ANY VESSEL THAT VICINITY LISTEN FOR CALLS AND CONTACT ITASCA. CALL NRUI ON 500 KCS. (NRUI is ITASCA's call sign.) This is the first request for stations to listen on 3105 and 6210. Ever since the last message heard from the plane ITSACA has been frequently calling and listening but has heard nothing. 03:10Z (3:40 p.m. aboard ITASCA) San Francisco Division advises ITASCA: "POSSIBILITY PLANE MAY ATTEMPT USE OF RADIO ON WATER AS RADIO SUPPLY WAS BATTERY AND ANTENNA COULD BE USED ON TOP OF WING. PUTNAM AND LOCKHEED STATE POSSIBILITY OF FLOATING CONSIDERABLE TIME EXCELLENT AND THAT EMERGENCY RUBBER BOAT AND PLENTY OF EMERGENCY RATIONS CARRIED ON PLANE." Nobody in San Francisco, including Putnam, could possibly have any idea what was aboard the plane on the Lae/Howland flight 04:03Z (4:33 p.m. aboard ITASCA) ITASCA asks San Francicsco: REQUEST FREQUENCIES EARHART EMERGENCY TRANSMITTER Nobody said anything about an emergency transmitter. The phrase "ANTENNA COULD BE USED ON TOP OF WING" may be a badly worded reference to the airplane's dorsal vee antenna which is "on top of wing", that is, it would be above water if the airplane was floating. 04:10Z (4:40 p.m. aboard ITASCA) San Francisco replies: SAME AS MAIN TRANSMITTER. POSSIBILITY PLANE MAY BE ABLE RECEIVE ITASCA 3105 VOICE. As far as we know, there was no emergency transmitter aboard the plane. 05:17Z (5:47 p.m. aboard ITASCA) PAA Mokapu notifies ITASCA that it heard "SOME TESTING ON 3105. STEADY CARRIER, NO MODULATION DECERNIBLE." No time is specified. 05:38 (6:08 p.m. aboard ITASCA) Sunset in the search area. At Gardner Island the tide is out and the reef is dry. 05:55Z (6:25 p.m. aboard ITASCA) The radio operator aboard ITASCA logs: WE HEAR HER ON 3105 KCS NW VERY WEAK AND UNREADABLE/ FONE Earhart. The operator is Radioman 3rd class Thomas O'Hare. He has just relieved Radioman 3rd class William Galten ten minutes ago. O'Hare had been on duty and had heard Earhart as she approached Howland that morning and, in fact, it was Tommy O'Hare who had logged the apparently erroneous "half hour gas left - sez she" entry. As can be seen from the previous traffic, ITASCA's perception of the situation at this time is that the airplane is down at sea and the occupants are either on the plane or in an inflatable boat and able to use an emergency transmitter. Hearing weak voice from Earhart on 3105 does not, therefore, conflict with their "situational awareness". O'Hare cannot make out the words but he identifies the voice as Earhart ("HER"). In HF transmissions it is not at all unusual for the words to be unintelligible but the tone and quality of the voice to be recognizable. It also seems safe to assume that hearing a woman's voice on the radio was an unusual occurrence in 1937. 05:55Z (6:25 p.m. aboard ITASCA) At exactly the same moment that O'Hare hears what he says is Earhart, PAA Mokapu hears, "STEADY CARRIER ON 3105 - NO MODULATION, VERY WEAK". ITASCA and Mokapu are apparenlty hearing the same transmission but ITASCA hears it better, and is apparently closer to the source, than Mokapu. ITASCA is northwest of Howland and there are no known possible sources of a 3105 transmission in the ocean between the ship and Hawaii. There are no other reports of signals heard anywhere at this time. 06:00Z (6:30 p.m. aboard ITASCA) ITASCA sends a voice transmission on 3105: "IF YOU HEAR US PLEASE GIVE US SERIES OF LONG DASHES. GO AHEAD PLEASE." 06:00 (6:30 p.m. aboard ITASCA) At that moment, aboard the British cruiser HMS ACHILLES, the radio operator logs: TELEPHONE TRANSMITTER WITH HARSH NOTE WAS HEARD TO MAKE "PLEASE GIVE US A FEW DASHES IF YOU GET US". This transmission ends at 06:03Z ACHILLES is approximately 1,000 nm southeast of Howland enroute from Samoa to Hawaii. 06:04Z (6:34 p.m. aboard ITASCA) ITASCA logs: HEARD SOMETHING LIKE GENERATOR START AND THEN STOP ON 3105. Two minutes later they hear the same thing. At the same time, ACHILLES logs: A SECOND TRANSMITTER WAS THEN HEARD TO MAKE DASHES WITH NOTE MUSICAL STRENGTH GOOD. Both stations describe a signal that is on and then off. 06:06 (6:36 p.m. aboard ITASCA) ITASCA then sends code on 3105: GAVE HER LONG CALL ON KEY This, of course, would involve sending the airplane's callsign, KHAQQ. At this time ACHILLES hears: FIRST TRANSMITTER WAS THEN HEARD TO MAKE KHAQQ TWICE BEFORE FADING OUT. 06:07Z (6:37 p.m. aboard ITASCA) ITASCA logs: SIGNALS ON AND OFF. THINK IT IS PLANE ?? SIGNALS ARE UNREADABLE (but) HEARD THE WORD EARHART. ACHILLES is apparently no longer hearing anything. PAA Mokapu, likewise, hears nothing at this time. Nobody else in Hawaii or on the mainland U.S. hears anything during this whole episode. 06:08Z (6:38 p.m. aboard ITASCA) ITASCA logs: CALLING HER ON FONE AND KEY O'Hare is sending both voice and code. 06:09Z (6:39 p.m. aboard ITASCA) ITASCA logs: HE IS ANSWERING US NOW 06:10Z (6:40 p.m. aboard ITASCA) ITASCA logs: STILL DISTORTED AND UNREADABLE/ BACK AT HIM ON KEY NOW O'Hare is now hearing a male voice but he still can't make out the words so he tries sending code. 06:11Z (6:41 p.m. aboard ITASCA) ITASCA logs: GUESS IT ISN'T HER NOW This is a very puzzling entry. Has O'Hare forgotten, or is he unaware, that there is a man aboard the airplane? 06:13-14Z (6:43-4 p.m. aboard ITASCA) ITASCA logs: QZ5 INTERFERING ON 3105 NOW - QZ5 CALLING KACA... We have, so far, not been able to figure out who QZ5 and KACA are. The callsigns don't match any ships or stations we can find listed. It may be that they are commercial aviation stations, aircraft or ground, in Hawaii (which would explain why QZ5 is sending code on 3105 trying to raise KACA). 06:15Z (6:45 p.m. aboard ITASCA) ITASCA logs: CALLING PLANE NOW ON FONE ON 3105 KCS The interference has apparenty stopped and O'Hare tries again. 06:16Z (6:46 p.m. aboard ITASCA) ITASCA logs: HE COMES RIGHT BACK, WHOEVER IT IS O'Hare gets an immediate male voice reply but he still can't make out what is being said. But then QZ5 is back sending code again, this time calling KCWR (whom we can't find either) and blocking the unidentified voice transmission. 06:21Z (6:51 p.m. aboard ITASCA) ITASCA logs: CALLING QZ5 NOW AND ASKING WHAT IS THE NAME OF YOUR STATION? This was sent in code. 06:24Z (6:54 p.m. aboard ITASCA) ITASACA logs: SOMEONE COMES BACK ON FONE. CALLED EARHART AND ASKED HER TO COME IN. TOLD OTHER STATIONS TO REMAIN QUIET / 3105 FONE 06:25Z (6:55 p.m. aboard ITASCA) ITASCA logs: ITASCA CALLING QZ5, WHAT IS THE NAME OF YOUR STATION, OVER O'Hare is sending code, trying to find out who QZ5 is. He sends this twice but never gets a reply. 06:26Z (6:56 p.m. aboard ITASCA) ITASCA logs: FONE SIGNALS DEFINITELY NOT EARHART Another puzzling entry. Has O'Hare heard more from the unintelligible male voice? He is sure that it's not Earhart but he doesn't seem to know who it is. It appears that he is dismissing the possibility that these are signals from the plane solely because the voice is male. 07:10Z (7:40 p.m. aboard ITASCA) ITASCA sends to San Francsico Division the first lengthy description of the day's events ending with: CONSIDER SEARCH RESULTS DEPEND UPON CONTINUED GOOD WEATHER AND ABILITY PLANE OR EMERGENCY BOAT REMAIN AFLOAT. HAVE HEARD NO SIGNALS FROM EARHART SINCE 0855 THIS MORNING WHEN SHE GAVE ITASCA A LINE OF POSITION BELIEVED TO MEAN RADIO BEARING AND STATED SHE WAS RUNNING NORTH AND SOUTH. ITASCA USING EVERY RESOURCE TO LOCATE PLANE. Note that the time of the last inflight transmission is wrong. There is no mention of the half-hour episode from 6:25 to 6:56 p.m. At this time ITASCA has no idea that PAA Mokapu and HMS ACHILLES heard corroborating signals. During that period ITASCA heard several direct responses to it's calls to the plane. Initially, Earhart's voice may have been reognized and later the word "Earhart" was heard. In one case ITASCA made a specific request and heard the specific response (dashes) it had asked for - all corroborated by ACHILLES. Both Mokapu to the north and ACHILLES to the south heard weaker signals than ITASCA heard at the same moment. Whoever ITASCA was hearing was apparently closer to ITASCA than to either of the other stations. If ITASCA was hearing a hoax, who was sending the hoax transmissions? If ITASCA was hearing someone else calling or talking about "Earhart" who was it? A simple reading of the original sources suggests that a woman and a man located somewhere between ACHILLES and ITASCA were sending voice messages on an aviation frequency - 3105 - and repsonding directly to ITASCA's transmission to Earhart. This was the beginning of the post-loss message phenomenon.

So if AE was > flying away from the Itasca and sending she may not have been heard. Also if > the Itasca is sitting in the proper orientation she could send and not be > heard, is that correct? I assume by "foot print" you mean the radiation pattern of the antenna. It is true that the signal strength at a given receiver is a function of distance, propagation conditions along the path, and the radiation pattern of the antenna. The radiation pattern is important because the amount of energy radiated along the propagation path is a function of the takeoff angle, which is the angle above the horizontal at which the energy is radiated. A simple way to visualize the radiation pattern of AE's antenna is to imagine a loaf of shepherd's bread, with the bottom sloping downward from the outer edge toward the center, instead of being flat. The distance from the center of the loaf's base to any point on its surface represents antenna gain, which is a measure of relative radiated signal strength in that direction, i.e. the antenna was radiating energy essentially in all directions, albeit at different intensities. The vertical angle between the center of the loaf's base and a given point on its surface is the takeoff angle. The gain of AE's antenna didn't vary greatly for takeoff angles between the zenith and about 15 degrees above the horizontal, but dropped off sharply as the takeoff angle decreased below about 15 degrees. The takeoff angle is important for signal strength analysis because it is determined by the height of the point in the ionosphere at which the signal is reflected back to the receiver at the surface of the earth. The height of the reflection point is a complex function of distance, frequency, time of day, and other factors. But in general, long distance paths involve very low takeoff angles, hence very low relative radiated signal strength. So as AE flew away from a receiver, the antenna gain in the direction of the receiver would decrease. Conversely, as she flew toward a receiver, the signal strength increased not only because the path was becoming shorter, but also because the takeoff angle was increasing and energy was leaving the antenna in more efficient areas of its radiation pattern. As for the Itasca, orientation was not a significant factor in reception. I have studied the design blueprints for that ship class and all the antennas installed at construction were sloping wires supported by the ship's single mast. So, the azimuth patterns of the antennas were essentially omnidirectional. Of course, it's possible that some antenna modifications were made during the period between construction and 1937, but it's unlikely that such changes would have departed dramatically from the original configuration, simply because there wasn't room or structure on the ship to do much else.

I am all for following out that hypothesis or any other. But if one can use common sense, then you have to realize that the shore party on Howland didn't see the plane come over, if the Itasca has lookouts also posted and they didn't see the Electra either, and with reasonable weather then I for one can't see how they would have come over Howland Island and flown away. That would have been the last thing they would do. They would crash land on Howland before going back out over the ocean. With a lack of evidence of where she did fly, then we are only left with postulating (that the same as fantasizing?) where we think she did fly.

If the castaway found in 1940 was Earhart then she survived for somewhere between several weeks to almost three years." I guess I don't see in your post the logic from which you derive the lower bound of several weeks. So let me speculate, and you can let me know if I'm close to your thinking ... AE and FN stay with the airplane for a few days until water is so high that it is no longer feasible, they spend a few more days at the northwest end of the island rifling through the cache of supplies left by the Norwich City, and then a few more days working their way around to the southeast end of the island where the skull is eventually found (and avoiding space alien abductions and Japanese who want to capture them along the way, which might add another day or two). Finally, because of the evidence of the clamshells, the castaway survives at least a few more days eating meals of clams. All this would add up to a few weeks. Regarding your upper bound of a few years ... how likely could a castaway avoid the cuts you describe (which lead to infection) for that period of time? Wouldn't normal daily activities and opening clam shells by bashing them on the top lead to periodic cuts? Naturally, I assume that if the castaway was AE, her supply of medicine and bandaids was minimal, as was her supply of replacement shoes and clothing. How did the Nikumaroro natives deal with cuts and infections? How long might we expect AE's shoes and clothing to last on Nikumaroro? LTM (Who never did figure out how to pronounce KHAQQ) Paige Miller #2565 *********************************************************************** From Ric My speculative lower boundary (a few weeks) is based primarily on the distance of the bone discovery location (whether or not it's the Seven Site) from suppose landing location, and the lack of clothing and other artifacts found with the bones. I reason that the longer a castaway survives on an island, the fewer relics of their arrival will remain. Naturally, not every cut or scrape you get on Niku is life-threatening. Remember, before the days of antibiotics people got infections all the time - bad ones - but they didn't always or even usually die from them. A bad cut and a bad infection would be more life-threatening on Niku than in other environments. Yes, you'd need to be pretty careful. The colonists on Niku dealt with cuts and infections the same way we do. The British had an excellent program at the Central Medical School in Suva, Fiji that trained "Native Dressers" in basic hygene and first aid. "Native Medical Practioners" (NMPs) were highly skilled and the next best thing to a licensed physcian. Each colonial settlement had a well-stocked dispensary. How long would clothes and shoes hold out? Hard to judge except to say, "Not very long." Clothes are largely superfluous unless you have modern sensibilites about avoiding the sun. Leather shoes, especially if they get repeatedly soaked walking on the reef or in the lagoon, rot very quickly. My guess - within a few weeks a castaway would have shed or worn-out most items of clothing and footwear.

Every time something makes sense, there always appears a curve. The only curve I have, is the time of day it was heard, for the frequencies AE had to transmit on. But I am not questioning Betty's honesty. Every time something fits, you get a new curve. For example the finding of the castaway's bones, only to have them disappear with out a trace and the person who found them to died shortly afterward. Or to have the search planes fly over, report recent sign of habitation, but to see no down pilots or the plane.

There was also a great deal of forum work done on identifying the particular radio her family had. Lots of web searchs, and downloaded images of various radios, and discussions of their capabilities, and quizzing Betty about what the radio looked like and how her father came to own it, etc. Your contributions to the forum have largely been in the form of postings like this one so you may not recall the research done by others. The primary field of inquiry that may never have gotten much discussion on the forum was the extensive research into the physical layout of the antenna at Betty's childhood home in St. Peterburg. Harry Poole did yeoman service, searching out and photographing the property and digging out old city records that established what it was like in 1937. Bob Brandenburg and Mike Everette spent many, many hours matching Betty's description of the antenna system to the plans of the house and property, then Bob modeled the theoretical performance of the antenna. The results of all that are written up in Bob's research paper "Harmony and Power: Could Betty Have Heard Earhart On A Harmonic?". You'll find it at: http://www.tighar.org/Projects/Earhart/Research/Bulletins/30_BettyHarmonic/30_Bettyharmonic.html It has been there since March of 2001. Oh yes, and there there was all the research that was done into the HAM callsign appearing in Betty's book and the discovery that it belonged to a HAM in Florida on the same great circle line from Gardner as Betty. Terry Linley interviewed the guy's daughter and discovered that he had once remarked that he had "talked" to Earhart. There's probably more but those are the lines of research that come immediately to mind. Throughout it all Betty has been there, patiently trying to answer whatever questions have come up. As for the other evidence that has been developed over the past two years-plus that fits the scene described by the notebook, I'm really rather surprised that you don't remember the Niku IIII expedition and the work we did out on the reef to confirm that a landing could have been made, and the tidal handcasting work only recently discussed on the forum, all of which supports the picture painted by Betty's book.

Before I discuss the infamous "signs of recent habitation" statement, and whether or not those signs should have been there, I would like to point out that I agree with Ric that there is evidence, albeit not conclusive, for Earhart having ended up on Niku. As Ric suggested, that evidence is [what I call] the "Big Four" as in the Dado, Plexi, Skin and the bones. I also agree with Ric that the "recent habitation" observation and the aircraft wreckage folklore provide additional clues. However, there is much more to Lambrecht's "recent habitation" statement than the short quote which is so often taken out of context. I have posted some of the following Lambrecht....."signs of recent habitation"....related information in the past. However, with the constantly changing Forum membership, I believe it would be good to review it again. In order to explore the Lambrecht quote we first need to ask ourselves: could there have been anything on the island that may have looked like "recent signs of habitation"? One answer is.....yes...Earhart and Noonan could have been there. But there are also many other logical possibilities. Lets take a closer look. Reports of various people leaving and/or seeing signs of previous habitation on Gardner/Nikumaroro Island are discussed below. Lets examine what other visitors saw/left and what they reported both contemporaneously and during later interviews or correspondence. This is not meant to be an exhaustive list of visitors to the island nor is it meant to exclude what Lambrecht saw as being Earhart related. It is meant to provide the interested reader with a full menu of items from which to draw conclusions about what Lambrecht may have observed on Gardner/Niku and, in addition, to speculate as to why a land search was not conducted.

Kenton Spading's field notes and pictures from NIKU III and various Email messages to TIGHAR members and the Forum. 5. TIGHAR TRACKS, June 15, 1993, Volume 9, Number 2 1. 1891, John T. Arundel's Project Mr. Arundel obtained a coconut (copra) license for Gardner/NIku Island from the British government on Feb. 1, 1891. A group of natives were left on the island that year (some were reported to have arrived prior to 1891....). Apparently the project was abandoned sometime in 1892. This project resulted in the construction of buildings with galvanized steel roofs and a large water tank all of which were later observed and described by the Norwich City wreck survivors (see below). Later, in October 1937 Harry Maude reported 111 coconut bearing trees on Gardner/Niku gone to riot from the Arundel period. See Reference No. 1, Tab No. 3, Doc. No. 15. 2. 1892, Her Majesties Ship (HMS) Curacoa When the HMS Curacoa visited the Gardner/Niku island on May 28, 1892, 20 Niue natives (under the command of an Englishman) were working on the Arundel coconut project. The British made a point of placing a Union Jack flag on the island as they were very concerned about documenting their claim to the island. See Reference No. 1, Tab No. 3, Doc. No. 15. We can speculate that, given the Englishman in command, native manpower and materials on the island, and with the possible knowledge that Arundel was preparing to leave later in 1892, that they may have constructed some sort of a permanent concrete marker or monument to hold the flag. They probably did not just stick it in a tree. 3. November 1929, Norwich City Wreck Mr. J. Thomas was a survivor of the S.S. Norwich City which ran aground on Gardner/Niku Island in November 1929. Mr. Thomas states in a hand written note, (original spelling and grammar left intact): "[On Gardner/Niku] Near the palms we found two desused galvanised roofed huts and a large water tank which were in a state [of] collapse, but which indicated to us that the island had at one time been inhabited most probably with a view of growing coconuts......." See Reference No. 1, Tab No. 3, Doc. No. 14. The huts and water tank Mr. Thomas refers to were undoubtedly left behind by the aforementioned John T. Arundel group. In addition, the Norwich City crew left behind two life boats and a substantial stack of provisions covered with a tarp. All of the above was in the vicinity of the wreck, a landmark which Lambrecht would have undoubtedly been drawn to. As an aside, in 1989, TIGHAR team members John Clauss and Veryl Fenlason photographed some very dilapidated wooden framing along the northwest shore of the island just north of the shipwreck. Upon reflection, these buildings probably dated from the Arundel period as opposed to the British 1938-1963 habitation of the island. TIGHAR also found the 1940 era British-built wood-framed COOP store in 1989 in a relatively intact state (although in a "desused" state). This suggests that Arundel's buildings and water tank may have survived fairly intact until Lambrecht's overflight in 1937 (only 8 years after Mr. Thomas observed them). Arundel's structures would have certainly looked "Recent" from the air (i.e. galvanized roofing) as opposed to the very "Old" adobe type walls Lambrecht saw on McKean (see Lambrecht's comments below). 4. Her Majesties Ship (HMS) Leith, February 15, 1937 The HMS Leith visited Gardner/Niku on February 15, 1937 just long enough to erect a flagpole and placard proclaiming the island to be the property of His Majesty the King. (Reference 1, Section 2, Item 2). Earhart disappeared and Lambrecht flew over the island, of course, roughly five (5) months later. As Lambrecht observed, someone indeed had visited the island "recently" in 1937. 5. Colorado Search Planes, July 9, 1937 The following are some quotes from Lambrecht's report. Most of Lambrecht's comments are quoted out of context on the Forum. In light of that, I hesitate to list them here as it is difficult to absorb Lambrecht's writing style, and therefore the overall theme of the report, without reading the entire document. At this point I am going to assume that the serious readers will carefully read the entire report on the TIGHAR web site in order to place the selected quotes in their proper context. Lt. John O. Lambrecht (and crew) reported the following (these are excerpts) after the flight over Gardner Island on July 9, 1937. See Reference No. 5, Page 6. [the quotes below are listed in the order that they appear in the report] ".........Enderbury, although a bit larger, was much the same as Phoenix. Here and there were what appeared to be oases with a few surrounding palm trees... no signs of habitation were evident and an inspection did not disclose the object of our search......" "........M'Kean did not require more than a perfunctory examination to ascertain that the missing plane had not landed here, and one circle of the island proved that it was uninhabited except for myriads of birds. Signs of previous habitation remained and the walls of several old buildings apparently of some sort of adobe construction, were still standing.........." ".......Here [Gardner] signs of recent habitation were clearly visible but repeated circling and zooming failed to elicit any answering wave from possible inhabitants and it was finally taken for granted that none were there........." [note the reference to "recent" on the heels of his reference to "old" at McKean, buildings with galvanized roofs would indeed look recent in comparison to McKean] "........There [Sydney] were signs of recent habitation and small shacks could be seen among the groves of coconut palms, but repeated zooms failed to arouse any answering wave and the planes headed northeast for Phoenix Island........" During an interview with Mr. Lambrecht in 1972 regarding what he observed on Gardner he stated that he saw "markers" (See Reference No. 5, Page 6). The "marker" Lambrecht remembers could have been a concrete monument/marker claiming British ownership from either the 1892 or the very recent 1937 British visit or something from Arundel or the Norwich City camp. 6. Eric Bevington and Harry Maude, October 1937 British subjects Harry Maude and Eric Bevington visited the island in October of 1937 to conduct a survey as part of a colonial resettlement project. Mr. Bevington stated in his diary that he saw "signs of previous habitation" on the island. During an interview in 1992 he stated that (as best he could recall) "it wasn't much.....like someone had bivouacked for the night" He indicated (without knowing where TIGHAR had been) that the place was near the area where TIGHAR found the shoe artifact in 1991 (SE part of the island). See Reference No. 2, Pages 6 and 7. Eric, however, could have easily seen something from the Arundel period or any of the later visitors. Dr. Tom King corresponded with Mr. Maude. He asked him about the "signs of previous habitation" that Eric mentions in his diary. Maude remembered it as being [a] "pile of sand" (see Reference No. 3). During the 1997 Niku III expedition, TIGHAR found relatively large piles of sand/coral on the SE end of the island near the shoe artifact site in the area indicated by Bevington. It looked like a Babai pit or an abortive well from either the British or Arundel periods. (see Reference No. 4). We don't have evidence that the Arundel group was in this area (the British colony was) but we have no evidence that they weren't and a search for well water could take you anywhere. Wrap Up Thoughts: Anecdotes aside....a lot of the information was recorded contemporaneously. I will say up front that Lambrecht could have seen Earhart related habitation. I will also add that I am offering some speculative thoughts here. My goal is to get people thinking about the issue in a broader sense than a simple partial quote from Lambrecht. We do not know what Lambrecht told his fellow shipmates and commander if asked....."What do you mean by "recent signs of habitation" However, it is not too hard to imagine that he told them he saw: 1. the flag and/or marker left behind by the British only 5 months earlier or 2. the life boats and stack of provisions left behind by the Norwich City crew...or 3. the corrugated steel roofs of the huts or the water tank or other debris left behind by the Arundel group earlier and noted by the Norwich crew in 1929...or 4. some or all of the above O-k, so there were "signs of recent habitation" available for Lambrecht to see (recent being a relative term). That begs the next question. Why was no land search conducted if obvious "signs of recent habitation" on Niku were reported? We can speculate that Lambrecht told his commander: "We checked out the island as best as we could. Repeated circling and zooming failed to elicit any answering wave. We tried hard, commander, to get the attention of anyone who might have been there. We saw no signs of an airplane and, in my opinion, the signs of habitation that we saw were not related to the lost fliers." The key words here for the commander were probably.....no signs of an airplane. The Colorado was sent to the Phoenix group on the strength of the post-lost signals/bearings. And the commander was told....the plane must be on land to broadcast. No airplane....no problem....lets move on. I am not prepared to fault the commander for this decision (there were also other good reasons to move on). It is much too easy in hindsight and from the comfort of our homes to do that. Getting a landing party on to and off of the island is a very dangerous affair as is positioning the Colorado anywhere near the island. As note above, Lambrecht's description of what he saw on Gardner and Sydney as "signs of RECENT habitation" may be an attempt to contrast them to the obviously much older "stone" ruins he had just seen at McKean Island. Indeed, in my speculative opinion, when you read the entire Lambrecht report within the context of which it is written, it can easily be interpreted that way. Thus he uses the word "recent" to describe Gardner after viewing the much older stone ruins on McKean. There is an additional piece of very speculative evidence that suggests Lambrecht saw but did not mention Arundel's huts. A Colorado crew member took notes as the ship visited the various islands. He had some artistic talent and as such drew pictures to accompanied his notes. For Hull he drew a canoe and people...and of course Lambrecht landed there and was visited by the locals in a canoe. For Gardner he drew a picture of native huts/houses. Summary: "RECENT" visitors to the island prior to Lambrecht's flyover include: 1) the Norwich City crew (8 yrs. before) and 2) the HMS Leith (5 months before). It is not surprising that he observed signs of recent habitation. Love To Mother Kenton Spading 1382CE ******************************************************************** From Ric As Kenton says, it all depends on how you interpret the words Lambrecht used. Are buildings that were "in a state of collapse" eight years earlier "signs of recent habitation"? Might Lambrecht have later decribed sheets of corrugated iron from collapsed buildings as "markers of some kind"? Is a flagpole or momument on the beach a "sign of recent habitation"? All of these interpretations, and the others that Kenton lists, are possible. I do however, think that it's obvious that Lambrecht intended to convey that he saw something on the ground that prompted him to "try to elicit an answering wave". I think that makes it pretty clear that when he says "recent" he means "current", not recent compared to the old ruins on McKean. Forget the phrase "signs of recent of recent habitation". Nobody knows what he saw. The fact is, he saw something that made him think there was someone down there who might come out and wave to him. No one should have been there, so either Lambrecht misinterpreted what he saw from the air or he saw something that should not have been there. It's as simple as that.

Reading between the lines, it does seem at least possible that FN was not actually "off his head" but was ill tempered, maybe through pain, maybe as a result of stress or disagreement on strategy, their position etc. He was possibly also frightened for his life, both in the short term as a result of his injuries and/or the submerging aircraft and in the longer term in that help might not arrive to save them from the rigours of a waterless tropical island. The architecture of the brain means that fear will often provoke anger as both emotions are controlled by the same part of the limbic system. The fact that at times he seemed more rational would support this. AE's reaction - pleading, tears, competition for the microphone could be equally ascribable to an angry and suffering Noonan as a deranged one. However, what little record we have of his supposed transmission is fairly perplexing. Bob, Uncle, Marie hey, take it away, etc - none of it seems the sort of thing that anyone, especially a navigator, would waste time on, especially when he was injured and it was so vitally important to give details of their position. This argues he really was deranged. On a separate issue, I was giving more consideration to "N.Y.". Can Betty rule out the idea that this was exactly what she heard (ie just those two letters) and it was not in fact an abbreviation for New York? Is it possible that she later gave it her own interpretation, being perhaps familiar with N.Y. as an abbreviation for New York? I can imagine if I was transcribing such a radio message, I would record the first time I heard " New York" as NEW YORK, but then in subsequent receptions abbreviate it to NY. To abbreviate it immediately would only seem rational if Betty was somewhat behind with recording what was said and had time to realise that "NEW" was not merely an adjective but part of a proper noun and so write N.Y.. If the possibility that NY might not mean New York is allowed, I would think that N.Y. is more likely a misinterpretation of NRUI. I know Ric claims that AE always referred to ITASCA rather than NRUI but I think that as ITASCA used this call sign when transmitting, there is every chance AE could have replied using it. Another thought occurs to me. Is it possible that AE had received a transmission from USS New York and was trying to contact it? I know this ship was in the Pacific in the early thirties but can't yet discover if it was so in mid 1937. Of course it may even have been in the Atlantic (perhaps even on a similar great circle path) since Betty's intercept was as far off as Florida. Perhaps someone could throw some light on this? Regards Angus. ************************************************************************ From Ric Betty has told me many times that what she wrote in her book were only fragments of what she heard.

Marty #2359 =============================================================== Date: Fri, 6 Dec 2002 07:28:23 EST From: Craig Subject: The Notebook Writing A question and a concern related to Betty's notebook. My question is this: What do you make of all the strange stuff that doesn't seem like it could be related to someone calling for help on a reef - i.e Marie Hey!, get the suitcase in my closet, etc. Could this be another signal on top of the one she was hearing? My concern is this: From the examples of the notebook you have on the website, it's strikes me as odd that in most cases, the song lyrics and other things she was writing are more often than not "messier" handwriting than that of the AE things. The AE stuff is neatly written, hardly ever runs into the margin, letter are mostly properly formed, etc. For instance, compare page 55 (one of the "messiest" AE pages) to page 38 (a song): - Page 38 runs into the border, words are inserted, crammed in, written in haste, the ink is fluctuating, etc. - Page 55 is clear, she never runs into the border, the ink is mostly uniform, and she even has time to write a line a second time for clarity. My thought on this is, if she is having trouble keeping up with the transmissions, wouldn't one expect to see her notes to be somewhat frantically written? Updated with things she missed when the transmission faded? There is the case that maybe she wanted to write neat in case this was important information, but did she know the importance at the time? Wouldn't the lyrics of a song be just as important to someone at that age? Craig ************************************************************************ From Ric Absolutely not. Betty's casual notation of song lyrics and doodling artwork are in marked contrast to her transcription of the words and phrases from Earhart. The emotional impact of what she was hearing was extreme and has stayed with her the rest of her life. She was very much aware, at the time, that she was hearing something important. =============================================================== Date: Fri, 6 Dec 2002 07:31:43 EST From: Chris in Petaluma Subject: Re: The Carol Theory Let me guess, Carols a blonde right?

As part of the interview, Betty went through her book page by page and described her recollections concerning each entry. Betty has given TIGHAR permission to make the tape of that interview available to the TIGHAR membership. We could offer the full interview and I'm happy to do that, but I frankly doubt that many people would want to wade through the hours of necessary, but not particularly compelling, background material to get to her notebook narrative. It would probably make more sense to offer a one-hour or so tape that presents the unedited notebook narrative. We could do that for $20 plus $5 for materials, shipping, and handling. We could do the full interview for $40 plus $10 for materials, shipping, and handling. The question is whether there is sufficient interest to justify the time it would take to put it together.

Now, we are taking that claim with a grain of salt, aren't we? His experience is not reported by him, we have a remark reported by a second person. There's no explanation of how ham frequencies intersect with aircraft frequencies or their harmonics, nor why a ham ( human being, nevertheless) did not report such a stupendous experience to ham buddies, any ham radio organization or magazine, or newspaper. I know in the past you have rationalized this, unless i misrepresent, by offering something like "people have many different motivations and reasons". Perhaps this man was in fact allergic to praise and fame, and indifferent to AE's fate, maybe he just wanted to swap cards. Seems less than likely, overall, to me, anyway. Now, where did he "talk to her"? At an airport? At some public event? Not related to above but on-topic maybe: I have been off here for quite a while, forgive me or ignore if this is redundant- does anyone have a concise comment about modelling this aircraft's antenna over ground, not an actual aircraft? I am looking for some typical resonance and impedance figures, thinking how to model that. I have a transmitter which will become a 3105/ 6210 test bed to measure actual harmonic output into a variety of impedances. Yes- with a similar output system to the WE set's "harmonic generator" system. Also- what are we thinking the aircraft used as a sense antenna for the loop? (This is a wire antenna used with the loop, to resolve the bare loop's 180 degree ambiguity. It could be a wire anywhere from just a few feet long, up to using the regular aircraft antenna.). I am thinking the belly wire was too far a run thru the cabin to be put to this use, and somehow the ship's main antenna was switched into this role. Or, are there 2 downleads visible anywhere on the top of the ship? I also acquired a US Navy loop quite similar, i think, to the expanded-spectrum commercial model carried by AE's plane, with an eye to seeing how it performs on HF with and without a sense antenna, as if for example, the main receiving antenna (belly antenna), is lost. My projects move at a glacial speed, however. Hue Miller ************************************************************************ From Ric We take everything with a grain of salt - and often a whole shaker. Anecdotes are anecdotes but the fact remains that the guy's HAM callsign appears in Betty's notebook. My best guess is that the belly antenna did dual duty as a voice receiving antenna and a sense antenna for the loop.

How can you back this up? It's hardly better than anecdotal. I know you were there and you talked to her, but we haven't. Isn't the best evidence we have the fact that she believed it to be real the fact she tried to send it to Goerner some 30 years later?

Maybe you should order the tape. =============================================================== Date: Mon, 9 Dec 2002 14:06:01 EST From: Ron Bright Subject: Betty's Notebook Entries I believe that the key to the origin of the signals that Betty heard and copied lies in the notations of "KGMB" and "31.95" written on her doodle page. The linkage between the two may yield some answers. Obviously, Betty heard those words/symbols spoken and she wrote them down at the time the other signals were coming in. But what is their connection? We know that KGMB the Honolulu radio station first broadcast the contact request message to Earhart on 5 July 1937. This request to Earhart asked her to answer with four DASHES on 3105. Almost immediately, as you point out, several professional stations heard four DASHES, but no VOICE on 3105. No mention of KGMB,etc. KGMB broadcasted in 1937 on 1320 AM with 1000 watts. We also know that ITASCA received that request for dashes somewhere in the vicinity of Howland. It is conceivable that Earhart had the potential to receive that signal. Betty received VOICE for about 3/4 of an hour on her radio, and by inference it is on a shortwave band, either 3105 or some harmonic, but not on an AM band. This is not totally clear as she said she had her back to the receiver as she tuned, but ordinarily she came home and listened to shortwave. She reported no reception of a KGMB broadcast requesting dashes, nor any KGMB broadcasting suggesting the March of Time 8 July broadcast. Early on in Tighars investigation, Mike E., the radio historian, posted that AE's Western Electric 20B receiver would only tune to 1200 kz because the tuning band had been modifed from 350-1500 to 485-1200 to cover the distress signal frequencies. He affirmed that change in a second post and provided technical details. He concluded that "...if KGMB was transmitting on 1320 in1937, she [Earhart] could not hear that station on the WE receiver." Other radio historians confirmed that KGMB in 1937 was broadcasting on 1320. He opined she may have had a second receiver. Never documented. What does this mean. I am not sure, but if Earhart could not receive on 1320, Betty could not have heard Earhart mention KGMB. But IF Betty heard KGMB on her radio AM band, she could have also heard the call letters of KGMB AND the 3105 reference. Did Mike E or Tighar ever resolve this technical question of reception on AE's radio? How positive are we that Betty heard the Earhart signals on shortwave not the AM band? Betty's notation of KGMB AND 3105 seems to be giving us a clue as to the origin. Could Earhart have transmitted the KGMB call sign as well as her 3105 frequency without hearing the KGMB request? I can't recall but did Betty add any more details to her transcription of the KGMB and the 31.05 (most likely 3105). LTM, Ron Bright ************************************************************************ From Ric Okay, first let's fix the typos or mistatements. Betty's notebook contains the notations "KGMB" and "31.05" (not 31.95) on a page of sketches four pages before the Earhart transcription starts. Betty has no recollection of making these notations but she does say that during periods when the signal from Earhart faded and she heard nothing, she would turn back to the sketches she was working on. She is, however, emphatic that she never adjusted the dial once she began hearing Amelia. Betty received sporadic voice for an hour and three quarters - from 16:30 to 18:15 local time - not three quarters of an hour. Betty does have a recollection of where the needle was on the dial when she heard Amelia and matching that position to the known dial of the Zenith Stratosphere indicates that she was most likely listening on a harmonic between 18 Mhz and 25 Mhz. There is virtually no chance that she was hearing Earhart on 3105 or 6210. See Bob Brandenburg's research bulletin "Could Betty Have Heard Amelia On A Harmonic" http://www.tighar.org/Projects/Earhart/Research/Bulletins/30_BettyHarmonic/30_Bettyharmonic.html The first KGMB broadcast to Earhart was not on July 5. It was at 20:00 Hawaiian Standard Time on July 3 (06:30Z on July 4). You are correct that the transmissions were on 1320 Khz. >Early on in Tighars investigation, Mike E., the radio historian, posted that >AE's Western Electric 20B receiver would only tune to 1200 kz because the >tuning band had been modifed from 350-1500 to 485-1200 to cover the distress >signal frequencies.

But Arthur Monsee, who heard and reported what he beleived was Earhart's transmissions, has an amateur call sign of W4BK. One of the first entries of Betty's notebook is the "W40K" Howland Port, presumably a call sign. From a listening capacity on a shortwave, that is pretty darn close, namely one letter off, the B for an O. The W40K was traced to another Ham on the Florida east coast. In 1937Monsee while living in San Francisco reported hearing "SOS KHAQ EAST HOWLAND LIGHT TONIGHT MUST HURRY CAN'T HOLD'". As you pointed out the words SOS, East , Howland, and Hurry, also ocur in Betty's notes. The words can't hold" occur in the 281 msg. He thought the signals came in on 7500 Kcs, not on a ham band. All in code, not voice. But you interviewed Monsee in Nov 00 and he was living in St Petersburg, Florida, where Betty lived in 1937. Now that is coincidence! When did Monsee move to ST Pete? LTM, Ron Bright ************************************************************************ From Ric Once again, first we have to correct the errors. Arthur Monsees callsign is now W4BK but in 1937 it was W6HJP. >The words "can't hold" occur in the 281 msg. No they don't. The words in the 281 message reported by USN Wailupe are "don't hold". Grammatically, it seems much more likely that the words were "won't hold". On July 6th HAM Charles McGill in Oakland claimed to hear "cannot hold out much longer".

It is both fascinating and chilling. One can turn the question around and ask what would have to happen by 0710Z for this to be a hoax. Each and all of the following must happen. Some could have a reasonably high probability, some were very unlikely. Let me attempt to supply the events necessary for a hoax to occur and provide a subjective guess at the probabilities (even though I am by no means an expert in radio transmissions). Each one of these individually, and all of them in combination, have to happen for these messages to be a hoax. 1. The hoaxer must know that Earhart has not arrived at Howland. (Probability: high) 2. The hoaxer must know that Earhart transmits on 3105 (Probability: I dunno) 3. The hoaxer must have equipment available that very day that allows him or her to listen and broadcast voice on 3105 (Probability: from what I have read, ability to broadcast on 3105 was not a common among radios of that day...thus I assign low probability to this) 4. The hoaxer must be able to broadcast in such a manner such that Howland hears the signal the strongest, Achilles next strongest, PAA Mokapu weakest, and no one else hears it (Probability: very low) 5. The hoaxer must be able to simulate a voice similar to Earhart's (Probability: medium) 6. The hoaxer must have a motivation to do this (Probability: low -- there aren't a lot of people who would do such a thing) Thus, I would conclude that the probability of these post-loss signals being a hoax is very low. It is much more likely that these post-loss signals are in fact really what they appear to be ... signals from Earhart. It is within the realm of possibility that the hoaxer could be the mysterious QZ5. Ric, you also say "A simple reading of the original sources suggests that a woman and a man located somewhere between ACHILLES and ITASCA were sending voice messages on an aviation frequency - 3105 - and repsonding directly to ITASCA's transmission to Earhart." While I agree with your conclusion, your phrasing intrigues me ... "A simple reading..." Do you have in mind a non-simple reading (yeah, I know about Occam's razor) that also makes sense? LTM (who often heard things no one else heard) Paige Miller #2565 ************************************************************************ From Ric QZ5 can't be a hoaxer because his code signals are interfering with the signals suspected as being Earhart's.

I have this stereotypical view of the sort of person who would perpetrate a deliberate hoax with other people's lives at stake. Of course, it's a young man with a slightly excessive interest in technology who probably does this sort of thing precisely because he's a bit isolated from female company, like your typical computer hacker today.

Interestingly, Earhart was on hand to see them off. The entire route was to be Honolulu to Fanning Island to Fiji to Auckland to Sydney. They had a three man crew, two pilots and a British merchant marine navigator. The airplane was an English A.S.6 Envoy from the Airspeed Company. Twin engine, retractable. The radio operated on 6675 and 500 kilohertz. They planned on sending radio messages 3 times an hour. They carried no life raft or life preservers, but did have "...12 pounds of rations, two gallons of drinking water, and a condenser with which fresh water may be distilled from salt." as emergency equipment. During the flight they made radio contact numerous times with various stations, including ships. However, the next morning at 10:45am (PST) they wired that they couldn't get their bearings ("We do not know whether we are north or south of the island."). After messages saying they had very little petrol left and were going into the water, they further sent, "We are turning into the wind." The last message (11:54am) sent just before ditching said, "Come and pick us up. The plane will float for two days." Most of the later messages appear to have been picked up by a Honolulu radio station, radio KYG, a Globe Wireless station. Army and Navy units (approximately 27 planes, 33 ships) undertook a massive search 300 miles in all directions around Hawaii. Even the Itasca was a participant. They were not heard from again, nor was any sign of wreckage ever found. No other messages purportedly from the aircraft were picked up by anyone.

This same fellow told his daughter, but apparently no one else, or else, very few people. Why is his ham call in Betty's notebook? She heard him, would be the likely answer. Forget her radio, antenna, signal path loss calculations to the South Pacific for a moment. Where did she hear him? On a multiple of 3105 or 6210? C'mon, radio experts. Ham HF radios produced in the last 10 years or so can be reprogrammed without too much difficulty to cover other bands. Ham transmitters of the 1930s were built to certain bands, such as 3.5-4, 7-7.3, 14-14.3, 28-30. This ham didn't just hear AE, he talked to her, he says. Betty says she heard him. Are we expected to believe Betty heard him transmitting outside of the ham bands? If so, did he have expectations beforehand of contacting AE ? Or, when he sat down that afternoon, did he decide to tune around the harmonic multiples of aircraft frequencies, instead of the ham bands. AE was also tuning around, and picked him up in the ham bands He picked her up outside the ham band, but transmitted in ham band? So they were "working in crossband mode" ? Readers, do you see any problem with this scene? Did this ham tell his daughter he "spoke with AE", or did he say he spoke with "AE" ? Is this the reason he didn't mention this event, which would have seemed to have been a major, major coup for this ham and for the whole hobby? Anyone else see a problem here? I didn't manufacture this problem for you. The interviewers report the ham callsign in Betty's notebook. And, we have mentioned the problem of a studio-like microphone in this live action scene, quite different from a microphone used for close-up work in a noisey aircraft cabin. So, again, why is this callsign in Betty's log? How does this fit with the ham's statement to his daughter? Not "it worked", somehow, "because Betty's account is true".

Fred was a newlywed, having just divorced his first wife and married Mary Bea while the Electra was being repaired following the Luke Field wreck. I suspect he had been something of a rake during his last years at Pan Am but during the few months he was associated with AE he was head over heels in love.

Flight Sim would not answer that question. Finally, the thought struck me that with all the opposition the Niku theory has had from some folks and with all the alternative ideas that have been presented, no one has been able to show that the Niku theory is not possible nor has any one been able to show one single substantial reason why some other idea is best. Doesn't prove Niku but it would seem to me that if there are opposing views something more solid should be offered in support.

It is a good point about a woman's voice being rare on the radio. My problem with hoax theory, is what would there be to gain from the hoaxer standpoint? Bragging rights to his friends? Not to mention you had to have a girl to join the hoax. If you look at the hoaxes people tried on Putman, years later, they were always with some kind of monetary gain in view. With any kind of hoax, there is always a reason. (Even Hackers are looking for something, mostly kids looking for popularity among fellow hackers, or again some one looking for financial gain) What was the reason for the hoaxes? (If it was hoax?). I read a book on the Titanic, and there were radio messages the first day, that the Titanic was being tow to port, it was a theory that perhaps those messages were broadcast to get more time to reinsure the cargo onboard.

Good post Jerry but I'm curious as to what specifically you are skeptical about and what specific question do you have of any individual piece of "evidence?" I can understand you have been given nothing to be absolute proof of anything and to hold your opinion in reserve but to be skeptical requires a specific reason to be so unless you are just generally skeptical of almost everything. As an example, let's take a specific artifact, the sheet of aircraft aluminum. What makes you skeptical that it came from AE's plane? Do you have reason to believe it came from a different plane or that it didn't come from a plane at all or it floated there? I understand the rivet holes have not been matched up with any known part of the Electra but I don't see that proves anything. I'm not trying to pick on you, Jerry. I'm trying to make a point that I started in another post. Just being skeptical isn't enough. There has to be an articulated reason or you won't get anyone's attention. I questioned the comment Noonan couldn't do Morse off the top of his head not because I know better or that I'm skeptical of that fact but because I thought I remembered reading that he used Morse code in his job with PANAM. I may have read more into that than I should have or missed something but Ric will quickly straighten me out. And so when you say you are skeptical I have ask of what and why. Alan *********************************************************************** From Ric Sorry. I can't help sticking my nose in here. I think that any reasonable person should have a skeptical attitude toward claims that could have important consequences. That approach is real basic (but, unfortunately, surprisingly rare). We all have a right and a duty to say, "Oh yeah? Show me the proof." When Jerry says he's skeptical I take him to mean that the evidence he has seen so far is not sufficient to convince him. That's fine. Everybody has their own threshold and no one can impose his or her own threshold on someone else. It's up to those who have already crossed their own threshold of credibility to come up with additional evidence that will convince others to follow their lead. Some will never follow (just ask Chuck Darwin) but you can't lose sleep over that. The important thing is to be open and honest about the evidence that is there. The danger is in people abrogating their right and duty to be skeptical and merely accepting the unsupported word of experts and authorities. We don't see much of that here on the forum, perhaps because the skeptical, show-me-the-proof approach is the essence of TIGHAR's Earhart Project.

No, Bill, that's not the only thing you can do. Anyone can toss ideas in the pot. But they are worthless without something specific behind them. We could suggest countless theories but that's a waste of time unless the theory has some kind of serious rationale and is pursuable. I don't know whether AE crashed and sank and if she did I don't know where. No one else knows either. The problem with that scenario is that there is not one shred of indication that happened. Nothing. Is it possible? Sure. But what do you do with the idea? There is no way to reasonably pursue it. Am I suggesting we ignore the whole possibility of crashed and sank. Absolutely. What else? You have nothing to offer on the idea and you want to toss the ball to the rest of us who also have nothing to offer on the theory. Why? Debate a totally untestable idea that has absolutely no rationale behind it? What could possibly come of that? Get your feet on the ground and go after the current theory or prove it wrong or that some other theory is correct. Debate won't get you there.

All the various reports of who did what are reviewed and compared and, eventually, there is an official report issued to support a finding of "probable cause". Nothing like that happened in the Earhart case, so we're left with a staggering array of disparate reports from the Coast Guard, the Navy, the Army, the Interior Department, the State Department, Pan American Airways, newspapers and wire services, and personal anecdotes.

Alan =============================================================== Date: Tue, 10 Dec 2002 12:36:48 EST From: Mike Everette Subject: Modified WE 20B receiver The WE receiver, as originally designed, tuned 550-1500 KHz on Band 2. It DID NOT cover 500 KHz as originally designed. The receiver was factory modified to cover the distress frequency of 500 KHz, by "fudging" the Band 2 tuning range downward. The new Band 2 range was 485-1200 KHz. The tuning range was obviously altered more at the high end than the low, losing 300 KHz at the top while the low end was changed by 65 KHz. There is a technical reason for this, as follows: This radio, like most others of the age, was capacitively tuned, that is, by using a multi-section (multi-gang) variable capacitor which varied the frequency of the 3 tuned elements: the radio-frequency amplifier stage, the "converter" or "mixer" stage, and the local oscillator. The shape of the plates in this variable capacitor resulted in the radio's tuning being varied in terms of "straight line wavelength." Wavelength decreases as frequency increases, but the rate of change is not the same; the frequency increases much faster than the wavelength decreases. Take a look at the AM radio dial on a manually-tuned car radio, or an older table radio. You'll see that the low end of the AM band is much more spread out than the upper. This is a holdover from the 1920s, when radio broadcasting stations were assigned their channels in terms of "wavelength" rather than exact frequencies in kilocycles (kilohertz). The WE 20B dial was set up in like fashion because the radio tuning circuit reflected a nonlinear calibration in terms of frequency... had it been calibrated in wavelenght instead (and it was NOT), the calibration would have been linear. That is, if the dial had been calibrated in METERS instead of KILOCYCLES or MEGACYCLES, the numbers would change in a straight line. However, the dial was laid out in such a way that the upper end of the tuning range on each band was "bunched" as the frequency increased, rather than having a constant spacing of calibration marks. So, if the low end of the band is lowered even further, you lose more of the top end. The bands on this radio, as designed, were (1) 150-420 KHz for aviation beacon, weather, control towers, which it would have been undesirable to change; (2) 550-1500 KHz, standard AM broadcast; (3) 1500-4000 KHz; (4) 4000-10000 KHz. Note, there was a gap, as designed, between 420-550 KHz. (By the way, the intermediate frequency of the receiver was 96 KHz, in case someone wondered....) The easiest and least intrusive way to modify the radio was to fudge Band 2 down; not to fudge Band 1 upward because too much of the beacon band would be lost. Note this well: If AE was listening to KGMB on 1320 KHz or thereabouts after she was down, as one post-loss scenario implies, I highly doubt she was doing it on the WE receiver... it would no longer tune that high, as modified. Looks to me, as if she must have had another set of ears....? Whether that means she had a second receiver, or that the WE radio had been replaced by another type, is still open to question. LTM (who hears EVERYTHING) and 73 Mike E. ************************************************************************ From Ric But how do we know that Earhart's receiver was modified at all? Where does it say that? Why would she need to receive on 500 Khz anyway? That was the international distress frequency and I can see why she'd want to be able to transmit on it, but why receive? The message traffic seems to indicate that if the receiver was modified as you say, nobody seems to have known it. On June 11, 1937, Coast guard San Francisco Division advised ITASCA: NO PLANE SCHEDULES HAVE BEEN ARRANGED WITH THIS DIVISION.

ALL PREVIOUS PLANE COMMUNICATIONS WERE HANDLED BY PAN AMERICAN AIRWAYS WITH PLANE WORKING ON 3105 AND PAN AMERICAN ON 2986 KILOCYCLES. The next day, June 12, San Francisco had this word about Earhart's intended schedule and use of her radios: FOLLOWING RECEIVED FROM MIAMI AIR STATION, "WHEN AMELIA EARHART TOOK OFF FROM MIAMI SHE STATED SHE WOULD NOT TRY TO COMMUNICATE WITH ANY RADIO STATION BUT WOULD BROADCAST HER POSITION EVERY 15 AND 45 MINUTES PAST EACH HOUR ON 6210 KCS. SHE ALSO TRANSMITS ON 3105 KCS. SHE STATED THAT HER RECEIVER WILL BE USED MOST OF THE TIME TAKING RADIO BEARINGS". On June 25, San Francisco advised ITASCA: MR PUTNAM NOW AT OAKLAND AND ADVISE MISS EARHART AT BANDOENG JAVA FOR REPAIRS TO MOTORS AND DEPARTURE INDEFINITE. SHE WILL CABLE DETAILS COMMUNICATIONS FROM PORT DARWIN DIRECT SANFRANCISCO AND YOU WILL BE GIVEN ALL INFORMATION IMMEDIATELY. ALL COMMUNICATIONS FROM PLANE TO BE ON 500, 3105 OR 6210 KILOCYCLES BY VOICE POSITIONS BEING GIVEN AT 15 AND 45 MINUTES PAST THE HOUR. ITASCA ADJUST TRANSMITTER FOR POSSIBLE USE ON 3105 KILOCYCLES FOR VOICE. DIRECTION FINDER ON PLANE COVERS RANGE FROM ABOUT 200 TO 1400 KILOCYCLES. On June 26 Earhart was still in Bandoeng, Java and sent the following to Richard Black, the Interior Dept. represntative aboard the ITASCA: SUGGEST ONTARIO STANDBY ON 400 KCS TO TRANSMIT LETTER N FIVE MINUTES ON REQUEST, WITH STATION CALL LETTER REPEATED TWICE END EVERY MINUTE.

Earhart is desperately trying to stay alive so she needs to save battery power and fuel to be able to run her radio and signal for help. BUT, she takes time out to listen to the soft mood music of ukuleles from Hawaii (was Arthur Godfrey on back then?) on KGMB? (And she just happens to tune to that station instead of other stations that weren't requesting four dashes. And she has battery power and fuel to waste.) She then hears them request that she send four dashes and slaps herself on the head and says to herself, "now why didn't I think of that?" She then fires up her transmitter on 3105 or 6210 and sends just four dashes. Why not add "QTH Phoenix Islands" or what ever island group she thinks she is on? Even if she and Noonan were not proficient with code they had plenty of time to write it out long hand and then "follow the bouncing ball" to send it (i.e. --.- - .... --. .- .-. -.. -. . .-. ) and send it out by keying the transmitter (if that was even possible) the same way she sent the four dashes. And what is wrong with "SOS DE KHAQQ" in morse, again written out if necessary. I would expect Noonan to have had enough contact with cw radio procedures to be aware of the "Q" code for these types of messages and for asking for radio bearings when they were approaching Howland. QTE? (--.- - . ..--..) was all he had to know how to send in order to request a true bearing from Itasca, not a whole lot of morse to know. I guess I must just be confused. gl (p.s. For you pilot types out there, it is from the "Q" code (which consisted of three letter groups each starting with the letter "Q") where the abbreviations of QNE for normal atmospheric pressure and QNH for airport altimeter setting come from. A pilot would request an altimeter setting by sending QNH? in morse.) gl ************************************************************************ From Ric KGMB was a powerful commercial station in Honolulu.

In any event, it's not at all surprising that she would have the frequency written down and I don't find it hard to believe that she tuned in KGMB to see if she could find out any news about the search for her - which she had to know was going on. Incidentally, KGMB was not the only commercial station trying to contact her. KGU in Honolulu also tried. Here are the instructions KGMB sent: "To the Earhart plane. We are using every means to establish communication with you. If you hear this broadcast please come in on 3105 kilocycles. Use key of possible, otherwise voice. If you hear this broadcast turn your carrier signal on one minute so we can tune you in, then turn your carrier signal on and off four times. Then listen for our acknowledgement."

I hear what you say but I have not seen any evidence what so ever that Earhart landed at Gardner Island. Hopefully, Tighar will proove it, or maybe somone will search and find the Electra 10E down deep somewhere. The reason I mentioned about throwing it up to the Forum is because as a new member here, I can only drag up theories that you have gone over and over before. I was hoping that any debate on my theory would get someone to agree or disagree with me. Your reply means that it works - And I learn from it. No one seems to agree with my theory that they first flew southward to avoid bad weather, then turned on a northern offset track. We have Earhart herself giving two positons back to Lae showing this is what they did. This takes them to about half of the flight. My question is that Tighar does not seem to recognize this as proof. Why is this so? To me this is proof that they at least ended up flying half of the flight on a northern offset track. Then we have a plane sighted from the SS Murtlebank (aproximately at the right time). Even, Ric, agreed with me that IF the Murtleband, indeed, saw a plane fly over, then one can assume it would be Earhart. This is not my proof but it falls right on the same track. From this point I see NO evidence that they continued straight or turned back toward a southern route to Howland and have to postulate what route they flew. Maybe both Tighar and I am right. first flying on a northern track, then flying on a southern track to Gardner, but this does not make any sense.

Specifically, we want to further our investigation of TIGHAR's hypothesis that Earhart and Noonan, and probably the airplane, ended up on Gardner Island (now known as Nikumaroro) in the Phoenix Group. We will not discuss conspiracy theories on this forum, nor will we debate whether the airplane crashed at sea near Howland. We feel that we have already established a strong probability that the flight arrived in the vicinity of Howland Island pretty much on schedule and, as of the last officially received radio transmission, had adequate remaining fuel to reach Gardner Island. The question is, did it? "Likewise, we will not discuss Earhart's personality, previous record-setting flights, love life, place in history, etc. unless it directly pertains to the discovery, verification, or disqualification of evidence relating to her disappearance. "Prior to posting messages to the forum, subscribers are urged to familiarize themselves with the evidence described on the TIGHAR website at http://www.tighar.org "We recognize that this forum is not for every Earhart enthusiast. Some may find us unsuitably irreverent or excessively scientific in our approach.

An animated version of how they think the Bismark came apart as it sunk to the bottom was very interesting. I think it would be very interesting if someone could create a similar version of the Niku hypothesis. For example, landing on the reef--surf action sweeping the plane over the reef and and sliding down to the ocean bottom. This would probably be very expensive but I thought it might be interesting if someone wanted to do it and had the time and resources. I think it would be very salable. I've seen other versions of this type of animation of James Dean's fatal car crash and of Ricky Nelson's plane crash. Again, it is probably wishful thinking, but I think it would be fascinating.

"Virtue is the mean between extremes" (Aristotle, Kung fu Tzu, aka Confucius, the Buddha). It's possible to exercise unreasonable doubt. Science makes progress because scientists do NOT duplicate each other's efforts unless there is good reason to do so. They tackle new questions for the most part. It's possible to exercise unreasonable trust. Even good people with lots of credentials can fall prey to "garbage in, garbage out" (GIGO). I do not intend to duplicate TIGHAR's trips to Niku so that I can see the place for myself. I do not intend to stand guard over Niku so that no one can salt it with counterfeit artifacts. I take TIGHAR's word about what it has found so far, and if any future expedition turns up better evidence, I plan to take the word of the team that they found the items where and as they tell me that they found them.

They checked him out (which they did not do with most of the other reported receptions). Wailupe had heard a fragmented message in badly keyed code between 1 and 2 o'clock on the orning (local time in Honolulu) of July 5th. The word went out to ITASCA about 45 minutes later. By July 6th the New York Herald Tribune was carrying a banner headline: "Earhart Flares Believed Sighted By Cutter Racing To '281 North Howland'..." McGill claimed to have heard a complete message in intelligible voice at 6:35 p.m. on July 6th. Nobody in the search area heard anything at that time.

I work in a military simulations center, and we simulate radio traffic with interconnected telephones, (higher clarity than the real thing), and you would be AMAZED at hown many times messages are garbled, mis-attributed, grid co-ordinates switched, etc. Picture this scenario - someone, lets say call sign WXXX sends a signal in voice, "WXXX for KHAQ, please transmit 4 long dashes on 3105". Some other station, WZZZ for example, straining to hear anthything from or about the Electra, partially hears the message as "...KHAQ.....send 4 ....dashes......3105" and replies in code "WZZZ - * * - ** - ** - ** - WZZZ QSL, whoch in turn is partially received by WXXX as....rough signal, four long dashes. You now have two people lead-pipe CONVINCED they have "spoken" with Amelia, and who knows how many others have "heard" her answer a message, when she MAY very well aleady be "sleepin' wid da fishes". Unfortunately, an Electra Down mesage grid, while useful, is unconclusive without a simultaneous log of Earhart related transmissions by other parties on appropriate frequencies and harmonics, probably an impossible task at this date. LTM (who knows not to attribute to malice what blind happenstance canaccount for) Rich Young ************************************************************************ From Ric First of all I'd like to hear why "Electra Down" is more correct than "Post-Loss". I chose the term "Post-Loss" because it makes the fewest possible assumptions. It's a term from my former career in aviation accident investigation and merely means events occurring after the time of the loss. Secondly, your point about messages being easily misunderstood is well taken, but it is largely irrelevant to most of the reported post-loss receptions. Of the 40 receptions heard by professional stations within 1,000 miles of Howland Island, only 3 contained intelligible voice (two on Howland, one on Baker); 22 contained unintelligible voice; 5 contained dashes; and the other 10 were only carrier waves. In most cases, stations farther away heard nothing or, if anything, a weaker signal at the same moment. To attribute these transmissions to misunderstandings there has to be a transmission to misunderstand. Within that area only ITASCA was authorized (and, as far as we know, had the capability) to transmit to Earhart on the aviation frequencies and 25 of the 40 receptions were heard by ITASCA. If you want to postulate that there was somebody else within 1,000 miles of Howland sending voice on 3105 I'd be interested to know who that might be. LTM, Ric =============================================================== Date: Tue, 10 Dec 2002 15:55:19 EST From: Rich Young Subject: Re: Carol's sword Relax everyone - I can almost guarantee you Carol's sword is NOT a "Samurai" sword, more correctly known as a katana. The metal scabbard is the first clue - if Carol will inspect the artifact, she should find an engraved chrysanthemum, (symbol of the Emperor) on either the scabbard, the sword, or both. This would indicate that it is simply a Japanese Army issue sword - issued to officers, NCOs, and under some conditions, to regular troops. A real katana would be far too valuable and precious to a family to be sent to war with eldest son, although occasionally a less valuable "junk" sword was known to have been carried by sine young officers in lieu of the Army issue sword, as a "good luck" piece. As to what the swords were used for, the eyewitness accounts leave no doubt - the swords were used for banzai charges, torturing and beheading prisoners, torturing and beheading civilians, and "persuading" otherwise unwilling women to "maintain the moral" of the Emperor's troops. Some officers actually had contests among themselves as to how many civilians they could decapitate in a given time, as documented in the excellent book, "The Rape Of Nanking". For some reason, the atrocities committed by Japan have never received the publicity that the Nazi Holocaust has, although their war-time behavior could certainly lead one to NOT discredit any Japanese culpability in AE's disappearance out of hand.

It seems to me that Ballard would be a good man to enlist to sweep Niku's reefs and lagoon, in search of the wreckage. Is this perhaps a possibility? Additionally, I understand that supporters of "crashed and sank" (particularly Long) want to believe that AE lacked fuel to get to Niku. Perhaps I missed something, but couldn't AE's "gas mileage" be further supported by reviewing data from all of her previous flights? Or has this been done, and I missed it? LTM, Alfred Hendrickson, PE ************************************************************************ From Ric TIGHAR has no relationship with Dr. Ballard and, frankly, we have been very disappointed in his recent exploits with National Geographic.

Someone asked how I know that the experince had an emotional impact on Betty. It's right there on the tape. There's an interesting sequel to that incident. Months later, Betty called me about something else but mentioned, quite concerned, " I don't understand it, but now when I read the words that I wrote in my book I can't hear them anymore."

I would like to flog the "Hoax Hypothesis" from one more angle. Note, i am directing this at only a couple specific distress messages overhead by NA radio fans. In 1941 there was a fellow in Illinois, i believe it was, broadcasting on shortwave, crude Nazi propaganda and dire threats about what would happen to certain people once Germany took over the USA. This incident was a subject of an article a few years back in Popular Communications. But the story would likely not have survived, to be recounted in Pop Com, here, or anywhere else, except for one thing - the story made QST, the official magazine of the ham radio organization ARRL. And why did it make it into QST magazine, and (apparently) not any of the radio listening hobby magazines? Because QST published a column castigating the Illinois hams from that area, for not reporting the hoax broadcaster to the FCC or other enforcement organization. And why did the Illinois hams who heard this malarky on the air, and sometimes talked with or argued with the hoaxer, on the air, and not just a couple times, not report it to anyone? Apparently because it might give the ham radio hobby a black eye, if it hit any kind of news media. ( The FCC eventually became aware of the broadcasts, tracked down the perpetrator, and arrested him.) To summarize: i am suggesting that if this particular ham and other hams in his Florida locale heard some "distress broadcast" that sounded really fishy, their response would be to not pass it on or publicize it. I am suggesting that IF the communications heard in Florida was a hoax, its suspect nature would have discouraged other radio hams, and this includes the one who said he talked with AE, from going anywhere or any further with talk about this incident. Which is what seems to have happened. In the past, i asked why such a broadcast as heard by Betty wouldn't be more widely heard, why it wouldn't be reported in the radio hobby magazines, in QST magazine, and why the ham radio world wouldn't be in a uproar over such a rare and near-miraculous communication. I think the reaction displayed by radio hobbyists four years later in this other case, may be a clue why so. Hue Miller *********************************************************************** From Ric Of the 41 receptions reported by non-professionals, 31 were reported by HAMs and only 10 by shortwave listeners (like Betty). All of the shortwave receptions were heard at different times but there were a couple of incidents where several HAMs reported hearing signals at the same time. I don't know any way to determine how many people, HAM or otherwise, heard signals that they did not report for whatever reason (desire to protect fellow HAMs or fear of ridicule or just not wanting to get involved) but I do know that absence of evidence is not proof of a cover-up. LTM, Ric =============================================================== Date: Wed, 11 Dec 2002 09:56:31 EST From: Ed Croft Subject: Re: Forum Attitudes Alan, Though your response was to Jerry, I have to pipe up as well. You see, I am a healthy (at least I'd like to think I am) skeptic, as well. I support (am a member) and appreciate the approach TIGHAR is taking to solving the mystery. I would vote that the weight of the evidence tips the scales currently to a landing at Niku vs a crash and sank. But I am too not totally convinced that Earhart landed on Nikumaroro. All a skeptic means is that you have doubts. >I understand the rivet holes have not >been matched up with any known part of the Electra but I don't see that >proves anything. I have to assume that the remark was made in jest when it is offered as evidence that one can not be skeptical about. It very well may be a patch to the Electra, but you know what Johnny Cochran would say. :) I consider Artifact 2-3-V-2, the Plexiglas, to be more convincing. What makes me believe are: the bones, the box with stenciled numbers and containing what was probably inverting eyepiece, Artifact 2-3-V-2, and what I am eagerly awaiting, the post-loss messages summary. I would have included the sole to the shoe, but Ric has discounted it, so I will as well. Argument against: - Big ocean, small island(assuming they were headed down the 157 line). They already missed one island - No messages after switching frequencies. - overflight of Niku by Lambrecht and no plane or persons found - 4 trips by TIGHAR to Niku without finding the smoking gun. Understand, I'm think that Ric and company are doing a great job and believe that it is likely that they made it to Niku, but I need more evidence. Hell, if I had 2 million, I donate the 400K to get the next trip underway now. The post-loss message summary due Jan 15 may push me over the edge. The Hooven report blew me away with the map of the Pan-American bearings. But I understand from Ric that some of the data is incorrect. Example of specific skepticism of evidence: Anecdotal evidence from Niku settlers(including Emily Sikuli) about seeing airplane parts. Would native islanders who had limited exposure to airplanes when they arrived on the island be able to discern the difference between an airplane part and a part of the Norwich City ? Per the website, the piece of unknown material in the early photographs that lay where Emily pointed to was part of the Norwich City. Also, what shape would any piece of the plane be in after being pounded by the winter storms ? One question(for Ric): There is on the website, http://www.tighar.org/Projects/Earhart/forum/Highlights101_120/highlights105.html#2, a posting discounting the 281 message. Excerpt below: The bottom line is that the signal strength, and thus the signal-to-noise ratio (SNR), at Wailupe for a signal from Gardner Island was so far below the detection threshold that there is no plausible hypothesis that would explain the "281" message having originated at Gardner Island. Has that analysis been discarded ? Plus, put me down for an edited version of the Betty interview (as long as it's a lot less than 400K) Ed Croft #2523 *********************************************************************** From Ric Thanks Ed. Yes, 25 bucks is a lot less than 400K. That's 17 and still counting. I'm sure Bob will reply to you query about the 281 message. As for how a Gilbertese colonist would recognize airplane debris - that has bothered us too. We do know that they had seen aircraft. In April 1939, the seaplane tender USS Pelican visited Gardner and it's Grumman J2F "Duck" had taken an aerial photo mosaic of the island. Emily told us of seeing her first airplane in 1938 when a Supermarine "Walrus" from a British cruiser had landed at Funafuti. Aluminum airplane wreckage looks very different from the massive rust-covered wreckage from the Norwich City but it still seems like the colonists would need to see something like a propeller or a wing to identify it as an airplane. =============================================================== Date: Wed, 11 Dec 2002 09:58:57 EST From: Hue Miller Subject: Re: Women on the radio Phil Tanner wrote: > I have this stereotypical view of the sort of person who would perpetrate a > deliberate hoax with other people's lives at stake.

Radio hobby magazines not infrequently report on cases of jamming of emergency or distress communications. That around the world flight a few years back, with an aircraft built out of synthetic materials (sorry, can't recall term for materials or name of craft right now), its communications to ground stations were jammed also, even though the working frequencies were not publicized.

In my experience, using a general coverage, single -conversion, tube-type radio receiver of this vintage, tuned to a signal in this frequency range, for a period that long, and not having to touch the tuning, seems sorta not plausible. For these frequencies, particularly with a weak signal, where even a little off-tuning drift would seriously impair reception ( and note, not necessarily drift back in, to correct the tuning - thus ruling out this as the cause of drift in/out), i have not found this to be the case with such type radios. And the high price, in those days, of her radio, did not really buy any better technology. In my experience, for minimum-retouch listening to SW on such radios, on the high band, you need 1) warm stable temperature for the radio 2) long warmup period for the radio to settle, drifting to minimize 3) strong signal The reason i bring this up is because this comment just immediately surprised me. I would appreciate if other readers would comment, based on their experience.

Something like a contemporaneous letter or work order. This is really simple to explain... the work was allegedly done in 1937. The mods were in effect a prototype for a later version of the radio, offered for sale by WE. This was documented in the 1939 book.

See the footage and notice how for a fraction of a second their bodies align and how both of them instantly alter position so they aren't. So, not only have they never been lovers, but both of them appear uncomfortable about the issue and thus, by quickly realigning, are either consciously or unconsciously letting the other know that no, never, no way, not a snowball's chance in hell, is it a possibility they'll ever become lovers!

The reason I don't like the term "Post Loss" is that it posits a "loss", (as in insurance "loss", a dmaged or wrecked item). While not yet convinced of the Landing On Gardner, (LOG) theory, it's not impossible that the Electra set down intact there or some other landfall, thereby not being a "loss" until wave action or other events destroy the plane. One can even posit taking off again on a short hop to gain altiitude for enhanced radio braodcasts, in such a situation. Recall please also that some of the Saipan stories claim an intact Electra was recovered by the military, and destroyed in 1944. However, we can safely assume that Pratt & Whitney's don't run without fuel, so any supposed radio traffic from the Electra after the time of maximum continuous flight fuel exhaustion would have to have occurred after the Electra was "down", at least temporarily. I guess you could say I try to be very rigorous about terms and what they may mean. As to who might have been talking voice, you can't have it both ways - if Betty can hear the AE in the Pacific, in Florida, on a harmonic, on a home set, as I believe you propose, then 3105 and 6120, assigned radio frequencies for aviation, could have "skipped" in from anywhere. LTM (who doesn't CQ DX much anymore) Rich Young ************************************************************************ From Ric The "loss" occurred when the airplane "went missing" (as our British friends would say). If I was filling out an accident report form on this "occurrence", under "date of loss" (D/O/L) I'd have to put "2 July 1937, sometime after 20:13Z". If the airplane later turns up in a hangar on Saipan that doesn't change the D/O/L any more than if a plane is reported stolen and later turns up in a hangar in ---well, Saipan.

It might be that inferring they were avoiding weather is what got you the opposition. Also your contention the then flew an offset wherein there is nothing to support an offset. There WERE some reported rain squalls about 300 miles east of Lae but that's not a navigation problem unless you are flying at a low altitude. AE's first report in which she gave a position that has been recorded was at S 7.3 150.7 E and 10,000' altitude. That was about a true course of 100 degrees, hardly south. Her next position was at 4.33 S 159.7 E which was a ENE heading back to course. If she flew that route it would have taken her almost directly over the highest mountain in the area, Balbi at nearly 9000' in Choiseul Province. That certainly is possible as they would have had 1000' clearance and if the weather was clear it would have been a great land mark. Another possibility is that the longitude of the first position report was written incorrectly and it should have been one fifty-seven degrees east rather than one fifty point seven degrees east. In that case the outbound course would have been 94 degrees and then a slightly sharper turn back to course but it would have taken them over NO mountainous terrain and still given them a good land mark heading out bound. You are correct in that those positions were reported and they most likely flew one of those two possibilities -- but to avoid mountainous terrain over New Britain or in the alternative both New Britain AND Bougainville (Choiseul).

We can probably exclude the fact that Thelma received a Japanese station harmonic on the basis that this was evidently a regular event. Although commercial stations do occasionally transmit harmonics with some power, it is usually inadvertent, temporary and soon corrected (as otherwise power is being sapped from the fundamental frequency).

Before I get started, I want to first try and down play some of this Japanese World War II racism that is present on this Forum. Since the AE/FN disappearance was in 1937, I don't think you can automatically attach "capture" to the Marshall island scenario. Why don't we call it "Japanese Rescue" instead of "Japanese Capture". There is no evidence that the Japanese exerted their control outside of their own Mandate in 1937 (except China that is). The "Japanese Rescue" idea wasn't a product of Hollywood but had roots in Jan. 1939 when it can be proved the U.S. State Dept. had such finger pointing by a French citizen. Randy Jacobson has the file, don't take my word for it. Alan you wrote: "...Next, I was looking at (heavens forbid) Flight Simulator last night and flew an Electra 10E from over Howland back toward the Gilbert's. It might be possible but because of fuel I wouldn't have tried it...." Alan, it was plan "B" after all, an escape plan so they could save their necks. This wasn't a suicide mission with only an hour of reserve fuel. You seem to acknowledge that the Gilberts was a possible escape route. It seems that you might have flown the recip of their inbound course to Howland starting from Howland. I use Howland too as a reference point even though we know that AE & FN couldn't have started there because they didn't see Howland OR Baker either. Alan these are a few of your own quotes; >.....We could suggest countless theories but that's a waste of time >unless the theory has some kind of serious rationale and is >pursuable.... >.....Jerry.

Alan do you really believe in what you are saying/writing, or is this just idle chatter? If you are truthful, I will invest the time in this post and hope it gets past Ric. This is for the flight simulator folks which is as close as we can get to >seeing< what could have been. Lets confine ourselves to known facts or post loss message content, specifically the "281 message". This message was believed enough for the Navy (CG) to move the Itasca and Swan to a point 281 miles NW on the LOP. FOR Ric, how long after the "281 message" was logged (0242 July 5th?) "...DONT HOLD WITH US MUCH LONGER..." (suggesting battery power?) was the end of post loss messages in the central Pacific? You gave us a time a couple of days ago on July 5th. We all recognize the 337/157* LOP and feel that Noonan could have accurately plotted this line through Howland. Alan, using the LOP through Howland as a base line, experiment flying 281* headings from the LOP. I have. You will probably have to invest a couple hours in this even accelerating the simulation to 8 X . The actually flight time would be closer to 5-6 hours starting from Howland. The first one I ran was the Mili recip scenario. I will save you time and just give you "point AE". "Point AE" is N 02* 30.10' W 177* 14.20' which is about 106 nm NW on the LOP. Set the wind at an easterly direction (85* - 95*) at 17 kts. Start at Howland and fly 337* DG at 130 kts TAS. Make sure you set TAS for the readout. Set the cloud bases at 2500 ft, tops to 5500 ft. Visibility at 20 miles. You can disagree of course. I set the GMT clock at 1912 GMT July 2, 1937 over Howland. I maintained 1000 to 2000 ft on this NW leg because for some reason AE reported 1000 ft without even seeing the Itasca. That altitude was a disadvantage. When you get to "Point AE", by reading the Lat & Long readouts at the top of the screen (shift-Z), turn the airplane to 281* and wait. Mili Atoll will appear in the windshield. The flight logged out in the book at 5.9 hours at Mili airport, .8 hrs should be deducted (106 nm / 130 kts) . That was starting at Howland mind you, where they WEREN'T. Don't bother looking for a gas pump at Mili. I then tried the "281" scenario south of Howland on the LOP. Again starting at Howland fly a heading of 157*. Keep the same 20 mile visibility setting. You will see Baker island (probably the source of the unidentified radio call signs) go by out of the left hand side window. You can't head 281 until it is out of sight behind you. AE and FN didn't see Baker either, so you have to wait. When you can't see Baker any more turn to 281* and again wait. Always keep in mind that the wind has a big effect in the simulation runs and it must be a constant factor in different scenarios. I ended up in the atolls around Butaritari airport (Gilberts) where I closed out the log book at 5.3 hours. North of Butaritari is Little Makin which is harder to see in the simulator because the aqua/shallow water area around it is very small. The simulation seems to be faithful in elevations above sea level and I think that would apply to depths below sea level for the aqua color. We are all familiar with "back to the Gilberts" as a possible "plan B". I simply suggest that 281* was Noonan's version of "plan B". There does seem to be a symmetry to the 281 experiments. 5.9 hours to Mili and 5.3 hours to Butaritari. "Point AE" was 106 nm NW of Howland. The distance that Baker is from Howland + 20 miles visibility would position the 157* turning point ~ 60 miles (?) SE. But again I must emphasize that we are using Howland as a starting point, where AE & FN definitely weren't AND we are not considering the "MISS" distance which caused this disappearance in the first place. If you like why don't you fly to Niku down the 157* LOP. You will have to adjust your own altitudes and visibility to make a visual on Niku. When you have the set-up let me know what it is.

(suggesting battery power?) was >the end of post loss messages in the central Pacific? Navy Radio at Wailupe heard the 281 message between 01:00 and 02:00 Honolulu time (11:30 to 12:30Z) on July 5th. For part of that time and for 6 minutes afterward, PAA on Wake Island hears "very unsteady voice modulated carrier" and takes a bearing of 144 degrees. In his report of July 10, 1937, the operator at Wake, Mr. R.M. Hansen, wrote, "At the time I believed this bearing to be accurate and I am still of that opinion." The 144 degree bearing from Wake passes very close to Gardner Island. At 13:50Z (an hour and 14 minutes later), PAA Mokapu hears "Carrier on again on 3105 but by the time we could open DF, signal was off again." At that time the water level on the reef at Gardner north of the Norwich City was about 20 inches - the highest it had been at any time since before the disappearance. That was the last time anybody in the Central Pacific (within 2,000 miles of Howland) -professional or amateur - heard anything suspected as being from Earhart. ============================================================== Date: Wed, 11 Dec 2002 14:36:05 EST From: Ron Bright Subject: Re: Harmonics vs ham frequencies Does that mean that Carroll's ham signals could not have been heard on Betty's shortwave set on one dial setting?

I > have to conclude that the position report was heard or recorded > erroneously. Randy, I'll repeat here my email in response to Bill. I have just revisited that issue which has bounced casually around for a long time. In Bill's note he felt he was being ignored or opposed when he wrote about the initial flight path being southward. I don't believe he was. The flak he got was for suggesting AE flew an offset toward Howland and that they deviated for weather. Neither point has been substantiated. Also they hardly flew south but only slightly so. Here is the explanation for that first "odd" position AE gave at 5:19 Z. Clearly I don't know exactly what they did or why but this is my measured opinion. AE's first report in which she gave a position that has been recorded was at S 7.3 150.7 E and 10,000' altitude. That was about a true course of 100 degrees, hardly south. Her next position was at S 4.33 159.7 E which was a ENE heading back to course. If she flew that route it would have taken her almost directly over the highest mountain in the area, Balbi at nearly 9000' in Choiseul Province. That certainly is possible as they would have had 1000' clearance and if the weather was clear it would have been a great land mark. Another possibility is that the longitude of the first position report was written incorrectly and it should have been one fifty-seven degrees east rather than one fifty point seven degrees east. In that case the outbound course would have been 94 degrees and then a slightly sharper turn back to course but it would have taken them over NO mountainous terrain and still given them a good land mark heading out bound. You are correct in that those positions were reported and they most likely flew one of those two possibilities -- but to avoid mountainous terrain over New Britain or in the alternative both New Britain AND Bougainville (Choiseul). Randy, I don't know what the weather or visibility was between Lae and the Solomon's but we do know there were rain squalls around 300 miles east of Lae. If they were above all the weather I would have a problem as to why they flew the reported course. If the weather was not all that clear then it makes perfectly good sense to avoid both New Britain AND Bougainville. If you will remember AE's first known report gave her altitude as 7,000 feet. That was at 4:18Z I've not figured a position for that time but roughly AE would have been around 400 or 500 miles out from Lae and still short of Bougainville. So she would be flying south of New Britain with Umbi Mt. (5,078'), Bamus Mt. (7375'), and Ulawun Mt. (7655') on he port and facing four mountains on Bougainville ahead two of which were above her flight altitude. Bagana Mt. (5741') and Loloru Mt. (6191') were about 1,000' feet below but Takuan Group (7251') and Balbi Mt. (8907') were above her flight altitude. Now if her correct 5:19Z report was 157 degrees east instead of 150.7 east she was safely past Balbi Mt. and at 10,000 feet. If instead the transcribed report of 150.7 east was correct and she was at 10,000' she would be flying almost directly over Balbi Mt. with only 1,000' clearance. I wouldn't have done that unless I could see clearly ahead. I would not have put my faith (fanny) on the line with 1937 altimeters and the "accuracy" of terrain measurements. Now as to the "wide" berth 7.3 degrees south gave you might think about that given Loloru was at 6.52 degrees south and the Takuan Group was at 6.442 degrees south. Balbi was a comfy 5.83 degrees south.

Perhaps I'm slower than usual today, but I don't see the logical connectivity here. If Betty heard AE on a harmonic, why does it necessarily follow that signals on 3105 and 6210 could have "skipped in from anywhere"? And even if such "skipping" occurred at the fundamental frequencies, what would that tell us about whether Betty heard AE on a harmonic. It would be helpful if you would provide a definition of "skipped in", and a discussion of the physics under which signals at 3105 and 6210 could have "skipped in" from "anywhere".

The operative question, IMHO, is which Japanese shortwave stations were broadcasting on which frequencies in those days. I have searched the web, without success, for contemporaneous references to such stations. Perhaps someone on the forum has access to shortwave magazines from 1937, which might shed some light on this question. If we can find a candidate Japanese station or stations and the associated broadcast schedules, it will be easy to find the transmitter power required at any given frequency for the signal to be hearable in eastern Canada at the reported date/time.

Somewhere in that thread the W.O.M.B.A.T. was born, but for the life of me I can't remember what the letters stood for. It sort of stuck anyway. Unfortunately, my health prevented me from pursuing the idea. My health is still shaky, but my yacht is going back in the water really soon. There is probably no reason to pursue the experiment at this late stage, but as I will be spending a lot of time on tropical coral rubble islands in temperatures between 88 F and 102 F in the shade, there may be a few experiments we can do if they are useful. We don't have any Bigass Latro running around though, just poisonous snakes, 4 foot long lizards, deadly almost invisible jellyfish and a few sharks. We're at 20 deg South by 149 East. Not Niku, but not too far off. One of my early plans is to see how long 750ml of water (a Benedictine bottle full) lasts under normal conditions on a hot day, walking and doing other things. This assumes that the castaway had access to water to refill the bottle, and carried it on daytime excursions around the island. All this is dependent on the yacht not sinking, as happened last time after years out of the water... If I can find a used pair of stoutish leather walk shoes at the op-shop I may try wearing them on the islands to see how they hold up to salt water, sand and coral rubble in reality, just out of curiosity. Another one I'm interested in is spending a few days on coconut juice to see what effect it really has as a water substitute, although I really do hate the stuff. Ideas? Suggestions?

My receiver, has a drift problem on SW up until it runs an hour, (I only have to adjust the tuner slightly in one direction, which I do it seems automatically, until it runs an hour) after an hour warm-up, it stops the drift, even on weak signals. I will give you, on the domestic AM band there is no noticeable drift (although I am sure there is), but it is because it is a strong signal. As far as more money did not mean a better receiver, it goes without saying. Many radios were price by the amount of tubes it had, 10 tube set was cheaper then a 20 tube set, but most of the 20 tube sets were really only using 10 tubes, the other 10 tube were there for show and you could brag about your receiver the manufacture could charge you more money. However I can't help but wonder what the extra tubes did, (if anything) as far as the heating of the set, which as you mention on your post is the cause for drift, generally the drift stops when the set reaches a stable temperature it manages to stay at.

When I was an active HAM in the 1960s I had a late 50s vintage Hammarlund HQ 110 for a hearing aid. It wasn't Hammarlund's top of the line (the 110 was only dual conversion, top of the line was triple conversion), but it pretty much represented state of the art receiving in the 1950s. It had a clock on it that had an auto start feature. You could set it like an alarm clock for the time you wanted to use the receiver and it would fire up the rig 20 minutes BEFORE the time you set so that it would be stable (warmed up) by the time you needed it. Stable was a relative term. My general coverage receiver in those days was a WWII navy surplus Collins (with a converted power supply). It drifted too. Performance wise, I would match those radios against anything modern with one glaring exception: frequency drift. But I don't think that was what Betty meant. Not adjusting the dial was just an expression meaning she didn't purposely change freqs to find something else to amuse her. She was riveted by the drama and stayed with it as long as there was something to listen too. The occasional minor adjustment to stay on frequency is a given. It is a part of using vacuum tube technology for short wave reception.

Alan =============================================================== Date: Thu, 12 Dec 2002 14:16:09 EST From: Hue Miller Subject: Re: Japanese radio station My own feeling on this is that it was more likely near the 3rd harmonic of the 6210. This works out to 18630 kHz ( marked "kcs." on the old dials. ) I seem to feel that this harmonic is more likely than the 5th of 3105 from the aspect of actual power radiated by the AE transmitter, but others judge otherwise. I don't see anyone has produced any convincing number for actual power radiated by AE transmitter on any harmonic. That is the reason i acquired a tube type transmitter to tune to both 3105, 6210 and measure the actual power output on these harmonics into typical antenna impedances. I do not have any figures for likely values for AE's antenna and i may have to mockup that and get ballpark figures. However, i admit, 5th harmonic of 3105 gives 15525 kHz, which fits *very* well with the 15000-15500 shortwave broadcast band ( "19 meter band), which is a daylight and afternoon band, so the propagation also is a fit. Shortwave magazines of the years do show regular A.M. hour reception of orient stations but i haven't found a good match, yet, myself. The harmonic i tend to favor for plausibility is 3x 6210 = 18630, which is a fair stretch above the 17500 - 17800 kcs. shortwave broadcast band. This is also a daylight band, moreso than the 15 mcs. band, and i think, for low power, is more amenable to long distance propagation. However, it is further "out of band" than the 15 mcs. candidate. I think we can rule out higher harmonics of both 3105 and 6210 on the grounds that 1) radiated power would be too low to make the trip 2) the harmonic frequency would be too far off the beaten track to have anyone tuning around there. Actually, thinking about this now, and recalling the console dial scales I have seen, even with a dial covering all the way from 7000-18000 or so in one band, the listener would still be looking quite closely only in the range 15000-15500, or 17500- 17900, even if the dial markings were only coarse, like 15... 16 ... 17...18...19, so the reception account and the math square pretty well for the 5th harmonic of 3105. > We can probably exclude the fact that Thelma received a > Japanese station harmonic on the basis that this was evidently a regular > event.

I don't want to muddy things too much, but i saw from the old radio magazines that harmonics of some SW stations were not infrequently heard. They were NOT corrected, but the lower power developed at these harmonics made them rarer reception. This kind of transmitting was not exceptional, but reception was, so we can rule this out, i believe. Ric wrote: > Sounds like the frequency was near but not necessarily on the Japanese > frequency.

The hoaxers had apparently also done their homework and were intimately familiar with the interior of a Lockheed 10 cockpit. They knew that in order to get out through the cockpit hatch you have to step on the pilot's seat, so if somone is sitting in that seat talking on the radio, the way out is effectively blocked. The hoax couple also knows that the cockpit is so cramped that squabbling would easily be picked up by the mic.

The "tuning" occurs by varying the value of an adjustable capacitor. It works like this - a knob on the front of the radio is connected to a shaft. A pulley on the shaft holds a cable that moves the frequency indicator bar across the dial face, and the shaft is connected to many metal plates, stacked, with space in between them, that rotate in and out of a stationary set of metal plates designed to fit around them. As more of the movable plates enter the gaps of the stationary plates, the capacitance increases. In this case, the insulator of the capacitor is air. Every time the temperature or relative humidity of the air changes, the value of the capacitance such a rig has changes, (this is part of the reason some radios had a "tuning eye" tube, to get back on freq.) Because the tubes, ("valves" for our Commonwealth brethren and sisters), need constant cooling, fresh outside air is constantly being drawn into the chassis. In my experience, (picking up BBC, time signals),, no more than 10 minutes elapse before it's necessary to "tweak" the tuning, (some radios had two knobs, one with a much lower gear ratio on the shaft for such "fine adjustment"). If Betty truly didn't have to adjust the tuning for almost two hours, she was picking up a very strong signal, which would tend to discount it being a subwatt harmonic skipping in from the Pacific. Speaking of skip, back during the "CB" craze, an acquaintance of mine shot skip with 1000 watts (voice, single sideband, equivalent to 3000 watts AM, around the 10 and 11 meter band) and a very good directional phased array antenna, (MoonRacker 4, if you must know). Although occasionally Australia and Europe were "DX'ed" from the Great Plains states of the U.S., even when both sides had comparable equipment and power, a ten to fifteen minute "window" was considered an exceptionally long conversation, or "QSO". Much more frequently, the station being worked would fade out before addresses could be exchanged. This makes me further skeptical that Betty could here a harmonic of a 50 watt transmitter, on a reef, (subject to salt spray, etc), into a non-directional, damaged, (by TIGHAR's own evidence), antenna array at an altitude of no more than 16 feet or so above sea level, for an hour and a half. In theory, anything's possible. The likelihood is another matter. Lastly, KGMB was on the air at that time, when it would normally be off the air, so that a flight of B-17's arriving in Hawaii from California could home in on it, not knowing, of course that the Japanese were planning to attack. Did Amelia, on any of her executed or planned flights to Hawaii, ever ask KGMB to stay on the air for this reason,(RDF)? Did she ever use any other broadcast band stations for navigating, and what were their frequencies? If she did, (or otherwise), it may indicate whether she had the capability to receive on that freq., via her main radio or otherwise.

I am attempting to find the power of JOAK in 1937. In 1925 it had only 1KW, but I know it was increased in the early 1930's.

However, the great circle route from Lae to Howland at 10,000' also clears all mountains along the route. Even with bad weather, a deviation so far to the right of 76*T (heading from Lae to Howland) just doesn't make that much sense. What makes better sense is that the position reported was transcribed incorrectly, which is what almost everyone concurs happened. The 0720GMT position report is smack on the great circle route, which seems probable that is was a Dead Reckon position postulated by FN, much as he did on the Atlantic crossing and Oakland to Honolulu. Also, we have evidence that the positions reported for the Oakland to Honolulu trip did NOT correspond to the times of transmissions, but were from 15 to 45 minutes old. While one can postulate a number of scenarios that fit all of the position reports from Lae to Howland, the one south of 7*S seems surreal to include. =============================================================== Date: Fri, 13 Dec 2002 10:38:03 EST From: Tom Strange Subject: Western Electric Radio Mods?

What's the basis for your statement? My statement is very broad on purpose, it is designed to cover all of the islands and all of the people of this area, and the rest of the world. The statement is to show that the world was shrinking at a incredible rate. Because of electronics, aircraft, and faster ships. In 1927 Lindbergh crossed the Atlantic, this added gasoline to the fire that was burning around the world. This fire was the exploration of the globe with aircraft. In the ten years that followed saw most areas of the globe visited by barn stormers, bush pilots,and pathfinders for airlines.

Or was it a one-way street? Could it be more significant regarding hoaxes or missunderstood post lost messages to consider not the receiving party, but instead to consider the transmitting party? No doubt there were millions of receivers capable of hearing AE, but how many transmitters in 1937 were capable of transmitting on either 3105 or 6210? If the transmissions from AE were a perfect match for Bettys radio, then we have one transmitter and one receiver. There seem to be no records of any other matchups that compare. That fits the profile of requiring more than one parameter to get a match between transmitter and receiver ie: antenna, skip wave character, harmonics, time of day, maybe even radio circuitry. The fact that no one else but Betty heard the transmissions seems to make it more credible rather than less when you consider the question of how many transmitters were broadcasting on 3105 or 6210 at that specific time. If AE's radio only put out 50 watts at peak battery, perhaps less with low battery power, then maybe only a skip wave reception was possible as opposed to a direct reception. That makes it more siginificant that there had to be a perfect match in the parameters between transmitter and reciever, creating a self imposed limit on the possible number of receivers. If there were millions of transmitters using 3105 and 6210 at that particular time that presents an entirely different picture.

One of these > was JOAK, the other was JZx. Harry, In fact JZx is a generic term for JZA JZB etc, which were different transmitters at the same site, transmitting on different frequencies depending on the intended destination. There were three for the USA and three for Europe, the 10.06 MCs being a "European" frequency in 1935. There were others for other areas. All the transmissions followed the same schedule. USA destined frequencies were 6750, 10700, 15620 in 1935. I don't know the frequencies for '37. 18910 @ 20KW and 18190 @ 10 KW were used in 1935 for Europe and Java respectively and could have been received in the US. 15620 was the closest frequency to an AE harmonic. One of the post-loss messages was supposedly received on 16525. This may have been a typo error for 15625 ( fundamental 3125 if 5th harmonic) - very close to 15620. And we do have evidence that AE's transmitter output was a little higher than 3105. Of course it may also have been an error for 15525 - the exact 5th harmonic of 3105. Even so, 15620 is closer to this harmonic than any other Nazaki frequency is to any other harmonic. >I don't find IZJ, Nor do I. >unless that is a typo from > JZx.

JOAK was the mediumwave Tokyo station which was relayed to the Nazaki transmitter and sent out via shortwave across the Pacific at 20 KW in 1935 under a series of call signs in a three letter sequence beginning with "JV." In 1936 an additional transmitter of 50KW was added under a similar series of three letter call signs beginning with JZ. By 1941 power had not increased from 50KW. Evidently the JV series transmitters were still running, in parallel with the JZ series, if the New York Times article for 1937 is accurate. This tends to be confirmed by the fact that the 50KW transmitter is described as additional.

There are a couple of possibilities. Apropos of Hue's remark that early commercial transmitters were less well controlled regarding harmonics than they are now, it is relevant to note that although the higher harmonics were at lower power, KGMB was a powerful transmitter of 1KW and if this is what Betty heard, even the higher harmonics would be relatively powerful too. Betty could have heard AE on 11th harmonic of 1552.5(17077.5) and KGMB on 13th harmonic of 1320 (17160) or17th harmonic of 1552.5 (26392.5) and KGMB on 20th harmonic of 1320 (26400) - especially if in the process of retuning due to drift. Another possibility is that AE actually mentioned KGMB. How was this possible if AE could not receive on 1320? Once again it is possible that she herself received KGMB on a harmonic whilst searching the frequencies for news of any search. It is also possible that AE mentined KGBM without having received it. It seems likely they would have had details of "local" radio stations with them for the next leg of the trip regarding radio bearings and weather.

This is EXACTLY what happened, Tom. We know that at the time of the first attempt, the a/c was equipped with the WE 13 transmitter and 2B receiver. These radios hit the market some time in late 1934 or at least by mid 1935.They were originally designed for voice operation only, receive and transmit. The radios had been modified to include 500 KHz coverage in both receiver and transmitter, and CW operation. The mods were performed by the manufacturer. If you look in the Morgan book you'll see 3 diagrams for the 13-series transmitter... one, as designed; one, as modified by American Airlines to update some of the circuitry with newer tube types in the oscillator and audio stages; and another showing the CW and 500 KHz mods. There is no diagram for the "modified" receiver but the mods are well described in the text. They were nowhere near as extensive as those in the transmitter since very little actual circuit modification was needed... change a couple of capacitor values (or add extra "padding" capacitors to lower the Band 2 tuning range) and add one extra tube in an external "adapter box" to serve as a beat-frequency oscillator for receiving CW. Radio at that time was pretty simple and straightforward (unlike modern radio which is 90% computer). The pace of radio technology was accelerating but had not yet hit the quantum leaps spurred by WW2. Still, the "design philosophy" of large manufacturers was like it is today... stretch a basic design to the limit before going on to something different. The transmitter mods weren't quite as well thought out as they could have been, in my humble opinion; and made the system cumbersome and confusing to operate on CW. I can fully accept the idea that these mods were the prototype for a later variant of the WE radios which were available on special order from the manufacturer. I have seen plenty of this sort of thing in my career in radio. Hope this helps.

So let's hear some reasonable hypotheses for how his call letters >ended up in Betty's notebook. Here it is.... The answer lies with a phenomenon called IMAGE FREQUENCIES. In superheterodyne receivers, the circuit opates in the following manner: The incoming signal is amplified in a tunable radio-frequency amplifier stage and then "mixed" with a second signal from local oscillator stage, to produce a third "Intermediate" or IF frequency, which is a fixed nontunable frequency. The local oscillator or LO is always spaced from the incoming signal by the value of the IF. Ideally, the value of IF frequency chosen should be at least ten per cent of the signal frequency, if not greater. That is, in a receiver tuned to 10 MHz, the ideal IF would be 1 MHz. The reason for this is that it is possible for "image" signals, unwanted frequencies which are separated from the desired one by double the value of the IF frequency, to "ride through" if the radio does not have sufficient "image rejection." This image rejection is a function of the signal frequency, the IF frequency, and the number and quality (selectivity) of the tuned circuits in the tuned RF amplfier stages of the receiver. It's a complicated story, but that's the short version. Now, in the real world, the "perfect" IF frequency is seldom used. Because the IF is a fixed frequency, it stays the same whether the radio is tuned to 1000 JHz in the standard AM broadcast band, or 18 MHz short wave. The image rejection will therefore be much greater(much BETTER, that is) in the AM band, and in the low HF range from 1.6 to 6 MHz, than at 18 MHz. Most radios of the era used an IF in the neighborhood of 455 KHz. Many suffered from poor image rejection on the short wave bands, especially the higher ranges which typically were "Band Three" on most of them, usually tuning about 6 to 20 MHz... some radios had only AM and one short wave range, and in that case, "Band Two" was usually about 6 to 20 MHz. If the radio was tuned to a short wave broadcasting station at 15.1 MHz, the LO might be working at 14.655 MHz (signal minus the IF frequency), to produce the 455 IF ny mixing with the signal. But if a strong ham radio signal operating in the 20-meter ham band, at 14.2 MHz came on the air, it just might ride right through the radio even if the set were tuned to 15.1 because the 14.2 MHz IMAGE was not rejected by the radio. It is VERY common in 30s-era radios to be able to hear images of strong short wave broadcasting stations, so the same stations appear at more than one spot on the dial... and that second spot might not even be within the short wave broadcasting band. Poor image rejection in these radios led to many cases, like the ham radio example above, of Hams being blamed for interference when it was not their fault at all, but was caused by design flaws in the home-type short wave set. Many uninformed listeners may have regularly picked up foreign broadcast signals, or ham signals, on image frequencies and not realized it... they just knew they heard certain signals at certain spots on the dial. it is therefore possible that some of those who heard post-loss signals may have not heard the alleged AE signal on its actual harmonic, but as a IMAGE... or, more likely, if other signals were heard (such as the Japanese broadcast station) near the AE signal on its actual harmonic frequency, those other signals may themselves have been images. Perhaps the ham call letters referred to in Betty's notebook refer to a ham signal she heard as an image, and thought it was on or near the same frequency as AE... hmmmmm. Very plausible. This possibility does complicate the matter of how to resolve exactly what frequency the AE signal may have used. I hope the above will help understanding of the problem, though it may seem confusing to non tech types. Now for some real-world stuff to illustrate: I have two restored 1930s radios, a 1935 General Electric five-tube tabletop set with no RF stage and excellent sensitivity, and a 1937 RCA nine-tube with an RF stage and almost as good sensitivity as my restored Hallicrafters communications receiver of something like 1960 vintage. Both the 30s sets tune roughly from the standard AM band through about 19 or 20 MHz. Both have 455 KHz IF frequency amplifiers. Both suffer from poor image rejection, the GE being noticeably worse because it has no RF amplifier to aid in cutting the images. If I listen to 19-meter shortwave signals in the 15.1 to 15.6 MHz band I can hear many images along with them, of ham signals in the 14-MHz or 20-meter ham band. When tuning in the region of 17 MHz I can likewise pick up many images of the shortwave broadcasts in the 15 MHz region, so the same broadcasts appear to be coming in at two different spots on the dial.... see? For the information of the tech types, Betty's radio is thought to have been a Zenith Stratosphere. I have the schematic diagram for this set. It has TWO radio frequency amplifiers, and TWO stages of IF amplification; plus, it has a variable bandwidth feature in the IF amplifier to add more selectivity capability. This radio was as good as many of the communications receivers of the day. Two RF stages would give it excellent image rejection; two IF stages would give it superior gain and selectivity. Many 30s-era radios had only one stage of IF. A good many didn't even have an RF amplifier stage but instead applied the incoming signal direct to the "mixer" stage, which resulted in very VERY poor performance regarding image rejection. In my opinion, any radio of the time which had at least one stage of RF amplification and sufficient "gain" in the IF stage could very likely have heard the alleged AE transmissions; maybe not as well as a Zenith Strat, but that depends on a number of external factors like signal strength and signal-to-noise ratio. That's Bob Brandenburg's department.

The path Niku - Florida was not a "one-hop" path, so (i think) you have the wave returning to earth elsewhere, before and past FL. Also, we are not talking vhf or CB-like skip here, and i doubt reception was limited to one backyard. Add in the length of time this broadcast went on, and it seems like someones else had a chance to hear this. No one else *reported* it, apparently. I cited an incident from 1941, i belieive Ric's objection that this was not a "hoaxer" but an "illegal spectrum user" is a meaningless differentiation, that for astute listeners listening in, it didn't matter if you called it a zebra instead, the fact was, in Illinois in 1941 was an egregious example of a radio, uh, illegal user, called by some a hoaxer, and *not one* listener apparently bothered to notify authorities, nor did the radio mags report it. So my point is, well, you know what my point is. > of how many transmitters were broadcasting on 3105 or 6210 at that specific > time. If AE's radio only put out 50 watts at peak battery, perhaps less with > low battery power, then maybe only a skip wave reception was possible as > opposed to a direct reception. The main course of thinking is now that the Florida reception was skip propagation (of course), but on a harmonic multiple of 3105 or 6210, and therefore with a modest fraction of the power output available on 3105 or 6210. I don't have any problem with the survival and post- loss signals heard thruout the Pacific area, these seem pretty unequivocally authentic. It's just ( i think) the 2 NA broadcast listener receptions that need more examining. Maybe we can figure it out, yet. BTW, this also occurred to me, on the OTHER hand: it was at Lae ( i think) where AE was advised to "pitch her voice higher" because of a rough transmiter signal. After communicating with radio ham users of similar transmitters (grid modulated), i sorta am very doubtful that merely mis adjusting the transmitter would result in that radical of a poor tone. I was thinking, if the microphone circuit in the AE transmitter had been set for high gain (instead of low senstivity, as normal), that would have put much more engine noise in the transmitter's audio. I don't recall if this switch was by solder connection or toggle switch inside the transmitter, but it could well have been reset one way or other by some ground technician along the way. My suggestion is, to think possibly that IF this was reset for high sensitivity (not normally used in cockpit environment) the background engine noise would have been much louder, which could have been countered to some extent by "pitching one's voice higher", above the lower frequency engine noise - AND - when engine not running, would have done a better job picking up cockpit sounds, with this more sensitive microphone setting.

John Jones is said to have the capability and coverup reason to broadcast on 3105 from Hull Island. I would be interested in your or other member comments. Regards Rick Washburn NH, USA *************************************************************************** From Ric Donohue, of course, offers no documentation to back up his speculation but there is abundant documentation to show that he is wrong. Jones, as an employee of Burns Philp South Seas Co., was overseeing a group of Tokelau laborers who were harvesting copra (dried coconut meat) on Hull Island. He had a radio receiver and transmitter (but there is no evidence that he had capability on 3105) until June of 1937 when his radio was destroyed in a famously hilarious incident. In brief - Jones was having labor problems. The Tokelaus (who were Christian) did not want to work on Sundays. Jones knew that a solar eclipse would occur on June 8 (a Monday) and warned the laborers that if they didn't work on Sunday he would cause the sun to be blotted out. They laughed off his threat and did not work on Sunday. On Monday, sure enough, the sun began to be blotted out and the terrified laborers ran to find Jones talking on his radio (possibly to the British scientific expedition party who were watching the eclipse from nearby Canton Island). Convinced that the radio was the means by which Jones had wrought this terrible evil, the laborers smashed the thing to smithereens. It was August before a replacement was delivered. Documention of this incident can be found in Eric Bevington's journal and in the logs of the ship that delivered the new radio. It will be recalled that when U.S. Navy pilot John Lambrecht landed in the lagoon at Hull during the Earhart search, he reported that the white overseer (Jones) was unaware of anything about the Earhart flight, much less its disappearance. Of course he didn't know about it. He hadn't had any contact with the outside world for the past month. It would be easier to prove that Jonesy was responsible for the eclipse than it would be to prove that he sent any of the Earhart post-loss messages. LTM, Ric ========================================================================= Date: Sat, 14 Dec 2002 10:35:48 EST From: Paige Miller Subject: Post-Loss Messages Ric, could you clarify an earlier statement? You said, "Within that area only ITASCA was authorized (and, as far as we know, had the capability) to transmit to Earhart on the aviation frequencies" ... did you perhaps mean that only ITASCA had the capability to transmit VOICE in that area? Because there was another station broadcasting in that area, the mysterious QZ5. Now, your description of the messages from QZ5, as recorded in ITASCA's logs, indicate that the second message from QZ5 (at 0616Z) was in code. I assume the first message from QZ5 at 0613Z was also in code, although you do not state that. Furthermore, to help me understand the status of radio messaging in 1937, let me ask if it is true that in 1937, most naval ships did not have the capability to broadcast voice? That the voice broadcast capabilities aboard ITASCA were put there specifically for the Earhart flight and would not have been present otherwise? All of this is important if we want to narrow down the set of possibilities for the voice transmissions heard by Itasca and Achilles that afternoon. -- Paige Miller *************************************************************************** From Ric All transmissions from QZ5 were in code and none made any reference to Earhart. Remember, 3105 was a standard aviation frequency and there was an active military and commercial aviation community in the Territory of Hawaii. Most ships and commercial aircraft communicated by code but ITASCA's voice capability was not installed specifically for Earhart. Early in the search it was recognized that the possibilty for misunderstandings was high, especially if numerous stations were trying to call Earhart rather than just listening for her, so the protocol was established that only ITASCA would call Earhart on 3105, 6210 and 7500 (the latter being the only frequency she had acknowledged receiving from ITASCA). The only other (authorized) calls to Earhart were by commercial broadcast stations KGU and KGMB but those calls were on their broadcast frequencies. ========================================================================= Date: Mon, 16 Dec 2002 10:20:12 EST From: Gary laPook Subject: Re: Harmonics Mike Everette wrote: > This is in response to several postings, including rhe following question > from Gary LaPook. > > > Re: Harmonics > > > > Does that mean that Carroll's ham signals could not have been heard on > > Betty's shortwave set on one dial setting? > > > >YES if she was set to a harmonic of 3105 or 6210. > > > >gl > >*************************************************************** > The answer lies with a phenomenon called IMAGE FREQUENCIES. > In superheterodyne receivers, the circuit operates in the following manner: > For the information of the tech types, Betty's radio is thought to have been > a Zenith Stratosphere.

This radio was as good as many of the communications receivers > of the day. Two RF stages would give it excellent image rejection; two IF > stages would give it superior gain and selectivity. But, as you point out, Betty's radio was a double conversion superhet (superheterodyne) using two different IFs (intermediate frequencies) so would have excellent image rejection and so this would not explain how Betty could hear AE on a harmonic of 3105, etc., and a ham transmitting in the hams bands at the same time. Your prior example using 455 kc as the IF would mean that we should examine the use of frequencies exactly 910 kc (twice the IF frequency) below the harmonics of AE's transmitter. (This assumes that the LO (local oscillator) is set for 455 below the tuning scale. If the radio was designed for the LO to be 455 above the tuning dial we should look at freqs 910 kc above the harmonics.) But with the more complex double conversion superhet used by Betty the investigation would be much more complex and we need to know the two IF frequencies. Do you know what they are? However, this investigation may not make much sense in that the whole reason for using the more complex circuitry of the double conversion superhet using two different IFs is to eliminate the problem of images and her radio probably did succeed in eliminating such images. Therefor she would only be able to hear AE on exact harmonics of AE's freqs. and she would not hear hams at the same time on the same setting of her tuning dial. gl 73 de KA9UHH ========================================================================= Date: Mon, 16 Dec 2002 10:21:48 EST From: Hue Miller Subject: Re: KGMB Angus Murray wrote: > How did Betty hear anything relating to KGMB?

Ummm....i'm not the ultimate authority on this, but i am thinking, from reading listener hobby magazines, and the harmonics from broadcast stations i have heard, that the harmonics actually heard, never in real life are heard over any distance at higher than the 5th, and more likely the 2nd or 3rd. I see from the 1930s radio mags that 6-Mhz broadcast stations from the Orient were heard in the USA on the 3rd, which is around 18 MHz ( 18000 kHz or kcs.). Also i remember somewhere in the TIGHAR compiled literature there was a mention of West Coast USA hearing Pacific aircraft on their 3rd harmonic. ( If you're sitting right under the broadcast station's antenna, you can probably hear those higher harmonics, as they're there, but in very low power.)

Angus, Assuming the 20 KW power is the effective radiated power - - including antenna gain - - the signal statistics are: Median SNR: 51 dB (in a 1 Hz band; 52 dB required for 90% intelligibility) 90th percentile SNR: 60 dB Standard deviation of the SNR: 7.03 dB Probability that the SNR will exceed 52 dB: 44.345 percent So, Thelma would hear a good signal on about 13 days of the month with that signal level. If the 20 KW power is not ERP, then antenna gain must be added. For example, an antenna with 10 dB gain in the direction of the receiver would deliver a median SNR of 61 dB, the standard deviation would be 0.78 dB, and the probability of good reception would be 100 percent. and Thelma would hear a good signal every day.

I think the name was Comdr Williams that put the charts together for AE.. He did calculate the distance using trig tables, probably H.O. 211 Ageton. A set of tables for star sight reduction. But the question is how did he plot a great circle course on a Mercator chart. Here is how. He took a globe of the world and stretched a string from Lae to Howland. on a globe this was a great circle. Next step was to make a mark on the globe about every 6 to 8 degrees of longitude Next step write down the Latitude and longitude of the marks and plot them on the mercator chart. Now connect the marks with straight lines. Great circle course. If he didn't have a globe he couldhave used a Lambert Conformal projection and plot the courese etc. You are right that AE did fly the course as Williams had laid out.

I (and lots of people, besides, me who use the Forum) are skeptical that they made it to Gardner in the first place. In, fact Tighar didn't always believe they did either at first. I think that, using common sense, we know that AE and FN were coming in close to the Itasca by the quality of their radio signals. What happen we do not know but their signal quality was not reported as decreasing which probably would have happened if they were heading away. Apparently, I am not alone in my thinking because other Earhart researchers and the Itasca think they came down NW of Howland. I will try and get Tom's book and maybe I can see why you guys believe that they came down on Gardner. I am still skeptical of a bone that is shorter and stockier than EA or FN, I am still skeptical of a female shoe that may or may not be hers. and a piece of aluminum that doesn't have the rivot holes where you want them. I bet if searches were done on other Islands in Oceana , other clues would be found there as well, so I and others will remain skeptical, just like you are skeptical of my hypothysis as well. Ric is right, I have no evidence that they "splashed" down NW of Howland, and neither has he that they landed on Gardner.

I have badgered the Marshallists till I'm blue in the face but they will not touch it. All are content to knock the Niku theory although they offer nothing to refute it. When I fuss at them instead of responding with substance they accuse me of trying to stifle opposing views or skepticism. Nothing could be further from the truth. I just ask for a little substance to their argument. I hope you have better luck than I have had in this venture.

I hope you can understand what I'm trying to postulate here. Its my understanding that shortwave radio signals "bounce" off the ionosphere. They radiate in EVERY direction. Can you take the distance from Niku and figure the bounce in every direction and see what the crossing patterns would have been at different points - like the part of Florida where Betty lived. My point is this. Betty had a VERY good receiver and a VERY unusual antenna arrangement. But was that enough to count for the difference. What about the likelihood that she actually was receiving the signal from more than one direction. Is it possible that she was getting the bounce from the west and possible also over the one of the poles (or both?)? Or maybe from both east and west? Can this be accurately tracked? In other words, was she possible at an "epicenter" which would could have received the signals from multiple directions, thus increasing the signal strength and possibly contributing to the "stability" of the signal, meaning that she didn't experience the drift normally expected with the set. Also, just for conjecture, what would have been the likelihood that Hull would have received signals from AE IF their radio set had not been damaged? Were they within the cone of silence or would they have been situated to have received her signal? I'm just asking because there are so many things that went "wrong" with the communications on the flight - ie. loss of the belly antenna, her having to pitch her voice higher, etc. Seems like fate handed her more than the usual number of problems. Murphy's law to the Nth degree.

I'm not altogether certain as the info is somewhat ambiguous! Having looked again, 15620, 18910, 18190 are listed with those for "international communication" so it could be that some under this heading were for commercial use. However, JVT (6750) is also listed under this heading and that was definitely a broadcast station and frequency. Frequencies which were separately listed which certainly were broadcast were JVT, JVP, JVN (confirmed by Harry), JVM, on 6750, 7510, 10660, 10740 in 1935 but these are out of band too. Could be that JVF (15620), JVA (18910) and JVB(18190) were commercial. Don't know the frequencies for 1937. I think the only way to be sure is to ask NHK (Radio Tokyo).

You seem to think that I require your guidance on what to consider in answering your questions. Let me assure you that such is not the case. I have been doing operations research in complex multidisciplinary problem domains for a long time. I routinely take into account my relevant experience and knowledge from all applicable disciplines. In this case, that includes areas other than "communications, generally". You have asked two distinctly different questions. Your first question seeks my opinion as to the likelihood that Betty heard Earhart. This is not a matter of opinion. The likelihood (i.e., probability) is either 1.0 or 0.0. There were only two possible outcomes. Either Betty heard Earhart or she didn't. Your second question seeks my opinion as to which outcome occurred. Based on my analysis of the currently available facts, it is my opinion that Betty heard Earhart.

JZJ and JZX (both 50KW) transmitted for the eastern districts of North America on 11600 and 15160 daily between 12.00 and 12.30 GMT in 1938. (IZJ was obviously a typo for JZJ.) News in Japanese and music. Seems likely this held good for 1937 as well, especially as the callsigns match. those listed for 1937. No other transmission times for other 50KW frequencies fit Thelma's reception time. However, neither of these frequencies is that close to AEs harmonics. 15160 is quite possible though because, as you pointed out, the frequencies only have to be similar rather than identical. Unless 15620 (20KW) turns out not to be a broadcast frequency, that seems to be the favourite frequency. Either way, I think we can be pretty damn sure that Thelma was picking up AE on the fifth harmonic of 3105.

The receive antenna, i think many agree, was gone. So, that leaves the loop, for mediumwave regular AM stations (KGMB etc) and - for as yet not definitely determined top frequency limit. Even IF the loop tuned up to 7 or 8 MHz ( Mcs. in old terminology, or 8000 kcs. ) how sensitive, how effective was the loop, together with its "sense antenna", whatever that was - the transmitter main antenna used in this role also, besides transmit - compared to the destroyed regular receive wire antenna?

The 281 message is curious because as Ric stated (not being a trusting soul I checked) is that Gardner is 280.5 nautical miles from the equator. Now for me, it is difficult to reconcile the words (phrases) in the message, 'north' and 'beyond north', with the Niku theory. But what are the chances that 281 would appear in a bogus message or from a message FN and AE tapped away from the Marshalls ? Especially as this is the exact piece of information that Noonan would give. Also, numbers in morse are somewhat easier to recognize because of the consecutive dits and dahs. Words are tougher because of the choosing of which combinations of 'dits' and 'dahs' go to what letters. With a proficient transmitter, it would be easy to distinguish because of the timing, but over a very poor radio signal with static, with an operator with limited skill, it obviously becomes much more difficult. For example (and these are just examples of show how close words are), 'call' in morse is -.-..-.-. ..-.. 'gardner' is - -..-.-.-..-...-. 'shut' is ......... -- 'ship' is ..........--. So, instead of 'Howland call KHAQQ' you would have 'Howland Gardner KHAQQ' (would be nice, eh ?) 'shut off' becomes 'ship off ...' I wrote a program (that's what I do for a living) to try all possible combinations, tried various words (reef, lagoon, plane, etc) but found no real matches. Also, it would make a big difference if the operators recorded abbreviations instead of complete words. Probably, what each operator thought they heard is written down on some piece of paper in some drawer somewhere, waiting to do a 'rosebud'.

Sunrise, as tabulated in the Air Almanac and in the Nautical Almanac, occurs when the upper limb (the top of the sun's disk) is in line with the visible horizon. Since the sun's disk has a radius of about 16 minutes of arc (which is known as "semi-diameter", which is published in the Nautical Almanac, and varies slightly during the year due to the variation in the distance from the earth to the sun) when you see the upper limb of the sun on the horizon the center of the sun is actually 16 minutes below the horizon. "Hc" (computed altitude) is computed for the center of the sun so the Hc at sunrise would have to be at least negative 16 minutes. However the story doesn't end here. The light from the sun is bent as it travels through the earth's atmosphere. This is called "refraction" and a correction for its effect must be applied to the computation of Hc. Refraction varies with the height of the celestial body above the horizon, the higher the object the smaller the correction. An object directly over head (at an altitude of 90 degrees) has a zero correction while an object at zero degrees elevation, on the horizon, has a standard correction of 34 minutes of arc. (This also varies slightly dependent on temperature and atmospheric pressure and the actual refraction can be calculated from tables in the Nautical Almanac.) Since refraction always makes objects appear higher than they actually are, the upper limb of the sun is actually 34 minutes below the horizon when it appears to your eye to be on the horizon. Since the center of the sun is 16 minutes below the upper limb the Hc at sunrise is actually negative 50 minutes, since the center of the sun is actually 50 minutes below the horizon. This is still not he end of the story. The minus 50 minutes Hc is only correct for an observer with his eye located exactly at sea level. If he observes from any higher height then he is looking slightly downward to the horizon and a correction for this additional angle (known as "dip") must be made to Hc. From a 1,000 foot altitude the dip is 31 minutes of arc and from 10,000 feet the dip is 98 minutes (which is 1 degree and 38 minutes). From 1,000 feet looking down at an angle of minus 31 minutes to the horizon the refraction correction increases slightly to 40 minutes instead of 34. So the Hc at sunrise from 1,000 feet equals dip + refraction + semidimeter so Hc= (-31) + (-40) + (-16) so Hc = -87 minutes or negative 1 degree 27 minutes. The refraction correction increases for observations from 10,000 feet to 50 minutes. So from 10,000 feet the calculation is Hc = (-98) + (-50) + (-16) = -164 minutes or negative 2 degrees 44 minutes. So as you can see from these examples the Hc at sunrise is always a negative value and is never zero. gl ========================================================================= Date: Tue, 17 Dec 2002 09:58:50 EST From: Randy Jacobson Subject: Re: antenna Clarence William's charts are in the Purdue University Library Special Collections.

To my mind the only two items, or bits of evidence, that I find closest to supporting the LOG scenario are the repair aluminum skin and the so -called "dado". I will address their individual problems separately, and their common problem at the end. 1. the skin. Despite all efforts, this pattern of rivet holes has not been matched to any area on an Electra. The best that can be said for it is that since Amelia's Electra was extensively repaired, we can't rule it out until such time as a good picture of all the repaired areas surfaces. But to support the LOG scenario requires affirmative proof, not "might-have-beens" - there is no evidence that this particular piece of aluminum was ever even attached to an airplane! It could have been used to patch an aluminum boat hull, canoe, water tank, or any other riveted item, (target buoy float, maybe?) If an aircraft carrier need to repair an aluminum item, I doubt that the intended nature of the metal for aircraft repairs would slow them down one bit, especially if they had a scrap piece the correct size and shape. 2. the "dado" - a common fixture whenever ANY "cargo" vehicle gets converted into a nice passenger vehicle. You will find fixtures such as this in almost any vehicle that has a carpeted area, especially conversions. I've seen them in boats, custom vans and buses, airplanes, camper trailers, even elevators. But the big problem they both have? Let's stipulate they both came from an airplane. Let's go even further, and for the sake of argument pretend we can prove that they both came off of AE's model 10E special. That still doesn't prove Landed On Gardner. Why? Because we KNOW that aircraft wreckage was imported from off-island for use as raw materials - remember the "bookcase" that TIGHAR was so excited about, until it proved to have come from a B-24 or Privateer? No such aircraft were lost on Gardner, so we know that the bookcase came over in a boat. Without affirmative proof contra-wise, Occam's Razor compels us to believe that ALL aircraft wreckage on Gardner arrived the same way, (until proven otherwise). You find some engines, main spar, landing gear, then we'll talk. small easily transportable pieces prove nothing.

Hc is calculated altitude - ie what the "real" altitude (from the centre of the earth to the centre of the sun with respect to a truly horizontal reference plane) ought to be if you are at your assumed position. But you can't correct a calculated altitude because it doesn't need it. Surely what you are talking about is Ho. Ho is the (corrected) observed altitude, and is given by Ho = Ha + Sum where Sum is the sum of the corrections (refraction, semi-diameter and parallax) and Ha is the apparent altitude, itself already corrected from Hs, the sextant altitude, by making instrumental and dip corrections. One then compares Ho and Hc and they both measure the same thing, ie the angle from the horizontal plane to the sun, Ho from the real position and Hc from the assumed position. Hs at sunrise (by the definition of sunrise) will be zero (assuming zero instrument error) and therefore Ho will be slightly negative. Hc will also be negative if one's assumed position is correct. So - Yes you're right that Hc will be negative but not because it incorporates any correction and only if your assumed position is correct. If your assumed position is wrong Hc could be anything.

I don't think they made it to Gardner for the following reasons. I will try to give you my deductive reasoning for each one. We know they first flew southwards, whatever the reason for this, It probably was for several reasons, including to avoid inclement weather which was about 250NM out from Lae, to avoid any of the mountains on the east end of Papua New Guinea, maybe they thought that communicating back to Lae would be better if they didnt have any mountains in between, and they could use Balbi Mountain on Bougainville as a navigation aid. (they didn't have to go over it, they could just skirt around it). 1. My 1st reason then would be what they did from here after they radioed back to Lae their first position. They then flew on a northward track where they called in their second positon. Which begs the question, why did they pick this more northern track when they could have flow directly to the SS Ontario, or even more directly to Howland Island. To me, They must have had a reason; they certainly wouldn't have headed on this track if they were trying to fly a southern offset. 2. my second reason is that there was a plane heard flying over the SS Myrtlebank at about the same time that the Electra 10E would have flown over it if, indeed, they continued on that SAME northern offset track. My confidence in the Electra flying over the SS Myrtlebank grew after some Forum members piped up and said that was indeed possible if not probable. And then Ric agreeing that IF the Myrtlebank heard a plane that night then it must have been the Electra. And those three waypoints do form a straight line. I have no more reasons for them continuing on that line from there. However, If one plots that continuing northern offset line you will see that it flies right over Ocean Island. Wasn't the plan for Ocean Island to be lit up for Earhart? That will be my next research. 3. My third reason why I believe in the northern offset route is that oddity that occurred on the 157/357 line at sunrise. He would have known that if at the appointed time he saw the sunrise then he was at the correct flying distance for him to turn to 157 degrees down to Howland. He would not have this oddity happen if he flew a southern offset route. One can argue that if his charts had Howland in the wrong place then he would have had a different distance to fly before turning onto 157 degrees, but I don't think we know this as fact. 4. When the Itasca heard AE saying she was short of fuel and flying at 1000 feet on then there would not have been enough time or fuel to go past Howland, Baker, or even down to Gardner (since this was not very long after sunrise then that would still put them north of Howland). AE was calling in every 30 minutes and since that was the last time the Itasca heard her while she was still in the air, then its easy to assume that they went down during that 30 minutes or their radio equipment failed. >Bill, am I to understand the reason you don't think they made it to Gardner >was because the "157/337" radio call was still strength 5? Oops, I better backtrack if I said this. If their radio signals to the Itasca were increasingly stronger then its easy to assume that they were closing with the Itasca. But It is a difficult time of the day to make assumptions on signal strenths, when the night frequencies are fading, and the day frequencies are getting louder all due to the Ionization of the D layer when the sun comes up. In gov't communications we had to change frequencies at sunrise and again at sunset to try and keep quality signals coming in. I have a fuel question. Has there been any debate on them carrying that Higher Octane fuel in that small tank? The plan was to use half of it to take off from Lae and the other half to take off from Howland. If they were that short of fuel, would they be able to use that second half to get them to Howland? Or would the Electra not want to run correctly when flying lower revs when landing? Maybe this would have lead to them coming down. I can imagine how hectic it would have been during those last moments trying to turn on the correct fuel lines, trying to get every drop out of them to keep the engines going.

So my challenge to you is the following: take something >that Ric CLAIMS is evidence in support of the TIGHAR hypothesis, and tell us >why, using logical arguments and whatever evidence you happen to have, Ric's >claim is wrong." I'll take a shot at it, Paige. First of all, let me emphasize that I don't know whether Ric is wrong or right. Having said that, here are some problems I see with the Niku Hypothesis: 1. The 1940 bones: Gallagher first identified them as a woman's. This identification was based, apparently, on part of a shoe sole (at least Gallagher gave no other basis for his conclusion). No personal effects, clothing, hair, etc., were found near the remains. Gallagher confidently identified the shoe as approximately a women's size 10. Assuming he was using British sizes, this would translate to a US woman's 11 or 12 -- far too big for Earhart, who wore a 7-8. The only medical men who actually saw and handled the bones (Isaac and Hoodless) agreed that they came from a male and had been exposed for a long time, perhaps 20 years. Burns' and Jantz' "re-analysis" calls this conclusion into question. However, what Burns and Jantz didn't tell you is that the pelvic bones are regarded as the most reliable indicator of gender. Hoodless' identification of the remains as male is based upon firsthand observation and measurement of a partial pelvis (the "innominate bone") and associated structures. Burns and Jantz' identification of the remains as >possibly< those of a female is based upon a computerized "re-interpretation" of Hoodless' cranial measurements -- a less reliable indicator. And even then it's a verrrrry close call. Further, Earhart's skull should have had a dime-sized hole in either or both maxillae, resulting from Caldwell-Luc operations performed at Massachusetts General Hospital in 1928 and at Cedars of Lebanon Hospital, Los Angeles, in June 1935. (It is unclear whether Dr. Joseph Goldstein, the 1935 surgeon, performed a second Caldwell-Luc or simply re-opened the 1928 portal). A recent medical study at the University of Reykjavik found that, in about 70% of patients who underwent Caldwell-Luc surgery, the drainage holes remained open >four to seven years< after the procedure; in 1937 Earhart was only two years out from the Goldstein surgery. TIGHAR speculates that the telltale surgical holes couldn't be seen because the skull's maxillae were missing, but cannot explain why Hoodless failed to mention this when he clearly noted that the right zygomatic arch and malar bone were missing. When I brought this up on the Forum, Dr. Burns responded, "We really don't know what Dr. Hoodless was looking for." With all due respect, horsefeathers. Dr. Hoodless was looking for indicia of who this person was and where he/she came from. He was certainly aware of speculation that the remains were those of Earhart; that's undoubtedly why the job was entrusted to him and no one else. There are other serious problems with the Burns/Jantz reanalysis, but I don't want to turn this into a treatise on Dem Bones, so let's move on. 2. Sextant box: There is no particular reason to believe this came from the Electra. It could just as easily have come from the Norwich City, or floated in from hundreds of miles away. (Parenthetically this is a problem I have with most of TIGHAR's evidence; there is a tendency to ignore or ridicule alternative sources of an artifact in favor of TIGHAR's own hypothesis. A good example of this is the 1940 bones: The body of at least one Norwich City crewman was never recovered, yet TIGHAR all but sneers at the notion this crewman could have been the unfortunate "castaway.") 3. Benedictine bottle: See (2) 4. Emily Sikuli: I still can't figure out whether Emily actually saw the "airplane wreckage" sticking up from the reef flat, or whether her dad saw it and told her about it. In any event her recollections are considerably less than clear, and were given some 60 years after the fact. (Why do I suspect that, if Emily's story did not support the Niku Hypothesis, TIGHAR would dismiss her tale as "mere anecdote," just as it does with Blas, Galten and others?) In any event, neither Maude nor Bevington (1937) nor the NZ survey crew, which spent >two months < on Niku in 1938-39, nor anybody else from 1938 through 1964, ever reported seeing this wreckage. However, Emily's remark about numerous skeletons on the beach does correlate with the story of Hull Island's John Jones, who, in 1937, told members of the Itasca crew that his ship, the "Makoa," had recently visited Niku and saw "the bodies of nine men lost in the [Norwich City] wreck, drown or killed by sharks were buried ashore, but wild pigs dug them up and their skeletons now lie on the beach." If these skeletons were still exposed when the first colonists arrived, that would be a plausible alternative explanation for much of Emily's story. 5. The 1991 shoe: For a variety of reasons, TIGHAR no longer contends that this shoe was Earhart's, and I agree. 6. Dado, plexiglass, etc. Apparently the dado is a "dado" because Ric showed it to one guy who said that's what it was. Based upon photos of the artifact, it seems overbuilt for its humble task, but that's just my impression. However, various other types of conveyances, including ships and automobiles, also have dados. Unless this hunk of metal can be specifically linked to a Lockheed aircraft, it's just a hunk of metal. The same is true of the plexiglass. It is also worth noting that the presence of a B24/PBY bookcase on Niku shows there was an inter-island trade in aircraft scrap. Any aircraft materials found on Niku must be viewed against this background. 7. The "Castaway Campfire": A can label found in the ashes proved to have a UPC bar code, indicating that it was deposited no earlier than the 1970s. 8. Clamshells, turtle shells, coconuts, etc: Evidence of somebody's lunch. Found near the site of the "house built for Gallagher," and also near clear remnants of LORAN activity. Absolutely nothing linking this stuff to Earhart except somebody's opinion that the shells were opened by an unpracticed hand. This could describe anyone who did not grow up next to the ocean, presumably including many of the LORAN guys. (I'm from Kansas; I would probably use a sledgehammer) 9. Betty's Notebook: So Earhart has enough presence of mind left to fire up the engine and turn on the radio, then she lapses into incoherence and spends the next 1.5 hours transmitting gibberish. Okay. But there's absolutely no "occult" information in the notebook, unless you count a random string of numbers which (when tweaked by Ric) correlates (sort of) with the position of the Ontario (several days previously.) And exactly why would AE waste her time transmitting the Ontario's former position -- twice, no less -- instead of something like "KHAQQ on reef south Howland"? Finally, even if one assumes that Betty heard Amelia Earhart, the notebook only puts them on land, not necessarily on Niku. Gilberts, anyone? 10. The Earhart 5K: I admit this one is subjective. I have yet to see a plausible explanation of why Earhart would leave the vicinity of the Norwich City (the most noticeable landmark on the island) and hike 3 miles around Ameriki (wading two inlets, carrying a sextant box) to set up camp at the Seven Site, just about as far away from the Norwich as you can get. Maybe the turtles and clams congregate only on the windward side; I dunno. 11. Lambrecht: Three search planes overfly Gardner Island one week after the disappearance. They are specifically searching for Earhart and her Electra. Six pairs of eyes. "Repeated circling and zooming." Lambrecht gets close enough to the Norwich to be able to describe its condition and estimate its tonnage. Yet nobody sees anything resembling aircraft wreckage. Nada. Zip. Squat. Whatever "signs of recent habitation" Lambrecht saw were inconsistent with makeshift castaway structures (he later said these signs were the "crumbling walls of buildings," and we know that ruins of this sort were present on the island from the 1892 Arundel plantation). To argue otherwise is to accuse Lambrecht of intentional dereliction of duty, and there is absolutely no evidence to support such a contention. BTW if you believe in the post-loss messages, then the utter and complete disappearance of the Electra from the Niku reef flat took place over four days, not seven. Does any of this prove that Earhart >didn't< land on Niku? Not at all. But let's remember that the burden of proving a hypothesis rests with the party asserting it. TIGHAR is attempting to do so, and more power to them. But I don't think they're ever going to get the job done with "probablistic" evidence, except maybe in their own minds. As Fred Goerner -- who himself had been burned by overstating his case -- wrote to a young, enthusiastic Ric Gillespie back in 1990: "If you return to Gardner, don't bring back more 'maybes' for publicity. If you bring something back, be absolutely positive you have clear identification before making the search for Earhart and Noonan more of a joke than it already is." IMHO better advice was never given.

Can you really see AE landing in a few inches of water if she could see an area that was still dry and tolerably good? It would be difficult to judge the quality of a submerged surface and such a landing would be prone to the dangers of hydroplaning. Does this not argue that either she landed opposite Tatiman Passage or at a time when both areas were already flooded? Since the balance of probability seems to lie with the area north of NC as a landing zone, then she probably landed after the water had covered the southerly area.

Remember the crystals for the two HF frequencies were one-half the air frequency. The crystal for 3105 was actually 1552.5; that for 6210 was 3105.

So the image of a ham signal might appear at 15310.... The harmonic frequency is 15525, not 15625. And yes, that is still a ways from 15310. At this point I am not splitting hairs with frequencies, but just looking at all possibilities that might be eventually plugged into an equation which itself isn't fully defined at this moment. Also consider the possibility that the IF might have been 465 KHz, another standard value of the time... this puts the image 930 KHz from the signal frequency.

Any radio with a 455 KHz IF will exhibit SOME image response, albeit perhaps weak, in the 12 to 25 MHz bands.... Even a quality communications receiver of the period such as a Hammarlund Super Pro SP-200 (hit the market in 1937) or a Hallicrafters SX-25 (1939) is not totally immune to images. You are quite correct to question how well Betty could have heard an image, given a superior radio like a Zenith Strat; the issue is certainly complicated if that's what she had. But I submit that it is not completely impossible, particularly with respect to images of powerful short wave broadcast signals. 73 Mike ========================================================================= Date: Wed, 18 Dec 2002 11:44:01 EST From: Angus Murray Subject: RCS Viti Forumites might be interested to view the website on R.C.S.

It expresses many of my doubts. My own answer to the question: "Why don't you believe that AE landed on Gardner?" is "Because she isn't there." Unless someone shows convincing evidence that she is now, or in the past was, there, then there is no reason to conclude that she was there. TIGHARs research and reasoning has shown that she quite probably could have gone there, and that there were good reasons she might have headed that way. But so far nothing has been shown which convinces me she arrived. Richard Young mentioned the shoe as no longer being positive evidence. He didn't mention that it has become negative evidence. Prior to their rejection the shoe parts were shown to probably be from a 1930s production woman's shoe of American manufacture. While this shoe, or the parts, could have been left by any number of persons any time between manufacture and discovery, the most probable person to lose a 1930s American woman's shoe would seem to be a 1930s American Woman. This implies the presence of an unknown woman on Gardner in the 1930s, other than AE. If we assume the reanalysis of the bones is correct, and they are those of a woman of European ancestry, then we are left with a question of which one. Are they AE's? Or did the woman who left her shoe on Gardner also leave her bones there. LTM Robert G.

I misread the sense of the original question. Ho will never be equal to zero but will always be negative. If you choose an assumed position at your actual position then the Hc will equal this Ho. Since you can assume a position at any place (within reason) since it is only used for ease of computation the resulting Hc could be of any value from minus 90 to plus 90 degrees. You usually choose an assumed position within 60 NM of your DR so as to minimize the difference between Hc and Ho which results in a shorter "intercept" and a more accurate LOP. BTW in aviation celestial navigation practice it is normal to do the computations prior to shooting the sun. You also figure out the corrections for refraction, semi-diameter and parallax, as you mentioned, plus corrections for coriolis, motion of the body, motion of the observer, and sextant error and apply them with the sign of the corrections reversed to the Hc prior to shooting the sun. This sum is abbreviated Hp, altitude precomputed. By doing this the Hp should equal the Hs and so you can compare Hs directly with Hp immediately after shooting the sun and plot your LOP in a very short period of time, much faster than if you are figuring out the corrections after shooting the sun. This speed is important since the airplane is moving rapidly and any delay in plotting the LOP means that you are well past it. gl ========================================================================= Date: Thu, 19 Dec 2002 08:12:24 EST From: Alan Caldwell Subject: Re: Post-Loss Messages Bill Shea wrote: >Alan Caldwell wrote: > >> Bill, am I to understand the reason you don't think they made it to Gardner >>was because the "157/337" radio call was still strength 5? > >I don't think they made it to Gardner for the following reasons.

In any case tell me what the coordinates of the Myrtlebank were at about 10:30pm that night or whatever time you think they over flew it.

I think you're confused about this event, Bill or I'm misunderstanding what you wrote. Nothing we know of occurred on the 157/337 line at sunrise. Sometime after sunrise which occurred while the Electra was in bound from the Gilbert area Noonan obtained at least two sun shots which gave him lines across his map running somewhat perpendicular to his course. Let's say, for example he shot the two sun shots 15 minutes apart. By measuring the distance between the two lines he would determine his ground speed. For the purpose of this example let's say the distance between the two lines was 30 nautical miles. That would give him a ground speed of 120 Knots. He then drew a parallel line through Howland and measured the distance from the second sun shot line to the line running through Howland. Using the time of the second sun shot line, the distance to the Howland line and his computed ground speed he would then know what time he would reach the line he drew through Howland. Let's say that time was 19:12Z. At 19:12Z he looked down and didn't see Howland so he may then have turned and run up and down that line which we all know as the 157/337 LOP. We don't know which way he went first or second or last. In any case they looked around and never saw Howland. Maybe at 19:12Z they were a little north or a little south or a little east or a little west of Howland. No one will ever know. That scenario is good no matter whether they approached Howland from north of course or south of course. Makes no difference. No "oddity" occurred. He knew it was the correct time to turn on the LOP only because of the time on his watch. Not because of the position of the sun or the position of the Electra. >4.

Sorry, Bill but that doesn't wash. First of all sunrise was roughly 6:15 to 6:30 local time but we don't actually know where the Electra was when they saw the sun come up. Around a couple hundred miles out at least. AE's radio call of "gas is running low" and "we are flying at 1,000 feet" came at 7:42 local. Long after sunrise. Nothing tells us where they were at 7:42L but THEY thought they were directly over Howland, "We must be on you...." (Same radio call) It was an hour later (8:43L) they reported "We are on the line 157 337....." They were NOT calling every 30 minutes. The reports listed are 4:53L, 6:14L, 6:45L, 7:42L, 7:58L, 8:00L, and 8:43L. At this time (8:43L) fuel reserve estimates range from my 139 gallons to 150 gallons or much more by Oscar Boswell. Oscar has shown they could have leaned out more than it has been thought. Contrary to your scenario, Bill, no one knows where the plane was at 7:42L but we do know where AE thought they were - over Howland. That was about an hour and a half after sunrise and if you feel that is "not very long after sunrise" I'll not argue. I will suggest, however, you have no basis for saying "there would not have been enough time or fuel to go past Howland, Baker, or even down to Gardner...." as they were still wandering around in the area at 8:43L at which time they gave no dire warning they were running on fumes. At 7:42L and at 8:43L there is no information in existence to tell us where they were other than within strength 5 radio wise of the Itasca whatever that means. I see no basis for assuming anything. Maybe AE stalled into the sea at that point, the aircraft had a disastrous event, the radios failed or she just flew off in some direction. There is no clue as to what occurred. >I have a fuel question.

Bill if I remember correctly the fuel tank contained 50 gallons of 100 octane fuel. I don't recall reading anything about a plan to use some of it at Howland but that would be reasonable to me. I don't see any problem with using up the remainder to keep from running out of gas and certainly they would have done that. I don't know what they had to do procedurally to use fuel from whatever tank but I think the 100 octane fuel was in one of the normal wing tanks not in the fuselage tanks as I understand it. If I'm wrong Ric will jump right in and correct me. Ric can also explain what it took to use fuel from the tanks but I don't see it as a problem. I don't recall a debate about it. Sorry to be so vague but I'm on my laptop in the living room and answering your post has me worn out and I don't want to get up and look through my files.

I said the radio had TWO STAGES OF IF AMPLIFICATION. The IF of the Zenith Strat was either 455 or 465 KHz. BIG difference between "two stages of amplification" and "double conversion." If you want a schematic of the Strat, go on line to www.nostalgiaair.com and I think you will find it. There are three variants of this receiver... two use 16 tubes each; the third uses 25 tubes, most of the "extras" being in a huge overblown audio amplifier. >Your prior example using 455 kc as the IF would mean that we should >examine the use of frequencies exactly 910 kc (twice the IF frequency) >below the harmonics of AE's transmitter.

I don't know which side of the signal the LO was on, in that radio... the more-or-less norm for 30s radios was, LO on the high side, since on the standard AM band it MUST be on the high side, given a 455 or 465 KHz IF; and tracking is much easier to maintain in the ranges up to 6 MHz if the LO is on the high side. BUT, assume for a moment that the receiver was not a Zenith Strat at all (for several reasons, and some are admittedly hunches, I am tending to lean more toward a Crosley 1199, which looks an awful lot like a Strat but was a helluva lot less expensive), and had only one -- or perhaps none at all -- preselector (RF Amplifier) stage ratrher than the Strat's two stages of preselection... in that case you might even hear images of strong signals as far removed as 1820 KHz (much weaker of course, but it is possible) in the higher tuning ranges above 12 to 15 MHz.

Clarence Williams USNR [whose father was a Navy Admiral who had been in Navy intelligence and who had been heavily involved in planning the US Navy's Pacific strategy for war against Japan in "War Plan Orange"] and his having plotted a great circle route for Earhart on her route from Oakland via Miami, the Caribbean, S. America etc. eastward around the globe to Howland and return to Oakland, I quote the following. Mary Lovell says on p.254: "After consultations with Clarence Williams, Amelia decided that since the second start was so much later in the year it would be safer to reverse the original flight plan and fly eastward because of the weather conditions in the Caribbean and Africa." On page 271 she says: "The charts laid out by Clarence Wiliams had been of immense help on the journey so far, though Amelia had not adhered strictly to the original flight plan. For the Lae-Howland flight, reciprocals of the original Howland-Lae attempt had been prepared, together with the local data regarding Howland Island that William had gleaned from the hydrographer's office in Washington." On page 293 she says: "At George's request, Clarence Willilams prepared a chart of the great circle 'base course' from Lae to Howland and on the assumption that Noonan would have obtained a drift angle soon after takeoff, he estimated drift at 11 degrees (which would have been laid off into the prevailing wind), or to the right of the original course. The prolongatons of this track, he said, passed 140 miles to the south of Howland Island. He also warned George that it was just as likely that the opposite might have happened, and drew another track line 11 degrees to the left of the course, which passed 140 miles to the north of Howland. From these two lines, he provided George with what he called a"cone of possibilities," which a staff artist of the Los Angeles Times laid out and wired to many of the daily papers around the world."

So far I haven't seen anybody meet that challenge. We've been treated to a rehash of opinions from people who find the evidence unconvincing and laundry lists of speculative explanations for the various events and artifacts that TIGHAR sees as indications that the flight ended at Nikumaroro. That's fine, but it doesn't answer Bill's challenge. What is most surprising to me is Pat Gaston's suggestion that I follow Fred Goerner's advice from 1990, "If you return to Gardner, don't bring back more 'maybes' for publicity. If you bring something back, be absolutely positive you have clear identification before making the search for Earhart and Noonan more of a joke than it already is." From the beginning we have conducted the Earhart Project as an investigation that is open to the public, researched by the public, debated by the public, and funded by the public. This forum is the purest expression of that openness and I find it more than a little ironic that Pat Gaston should use the forum to express his opinion that we should not be discussing all these maybes. Perhaps in the past twelve years since Fred Goerner offered that advice, TIGHAR's expeditions, publications, website and forum have made the search for Earhart and Noonan more of a joke than it already was.

If this is the case (and we assume they were indeed on the LOP - because they reached Gardner) then any error in choosing direction on the LOP ought to have been rectified fairly soon and the minimum amount of fuel wasted in running in the wrong direction. How long do you estimate it might have taken to establish they were going away from Howland (if this was in fact the case), with and without a pre-comp curve?

That gave them (roughly) 1100 to 1115 gallons, of which about 40 was 100 octane. Alan you are correct that this was in one of the wing tanks. We don't know which side it was on, but that doesn't matter. I don't recall if there was 100 octane stockpiled at Howland. Ric may know, but if I had to guess, I'd bet there was. I don't recall what kind of management plan they had for moving fuel around to keep balanced, but I am willing to bet there had to be some kind of methodology, whether it was simply keeping track and switching tanks so as to use fuel evenly from the various tanks until they were (nearly) empty, or physically moving fuel around. As I recall Ric did mention recently that the Electra was equipped with a wobble pump for that purpose. However, I can't imagine trying to move hundreds of gallons of fuel with a wobble pump! I'm much more inclined to think that once they had taken any given tank down to a few gallons and switched over, then they probably moved the residual to another tank. ltm, jon 2266 ========================================================================= Date: Fri, 20 Dec 2002 11:20:56 EST From: Alan Caldwell Subject: Re: Antenna Ron Reuther wrote: > The prolongations of this track, he > said, passed 140 miles to the south of Howland Island. Ron, I would suggest you plot that out on a map. As a long time pilot and navigator I can tell you that makes no sense. An 11 degree offset would bypass Howland by something in the neighborhood of 410 miles no wind. Clarence Williams had no way of knowing what the wind would be nor did Noonan. There were insufficient weather reporting stations to have ever predicted any drift accurately for actual use. With the little information we have now after the fact there is no way to compute what the winds were on July 2, 1937 or redraw the route. If we can't do it after the fact I am certain it could not have been done before the fact. The drift only affects the heading of the aircraft. It doesn't alter the course. You don't draw offsets for wind on maps. In the case of a short distance a "cone" of probable drift might be guessed at but I don't know for what purpose. In all the many years we navigated across both oceans our preflight planning consisted of no wind information. Known winds were applied at take off time and periodically throughout the flight. I have to believe Noonan did the same thing. If you will stop and think you will see that an 11 degree drift would require a pretty strong wind or a significant angle off course. There is no evidence either condition existed. In any case drawing a line 11 degrees both sides of track makes no sense whatsoever. There is no data available that would allow one to arrive at a point 140 miles either side of Howland. I'm not sure I would put all that stock in what Mary Lovell wrote in a book or what anyone wrote in any book. This was difficult to respond to as it is too nonsensical.

One of the things that these folks seem to have overlooked is, when TIGHAR/Ric - researches the evidence and finds that it _doesn't_ support the Earhart theory, it's put right out there for all the world to see. The (B-24) mapcase for example, or the "knob" that turns out to be an oil can spout. There is also the fact that none of the evidence identified and examined thus far has been touted as the proverbial "smoking gun". However, I do believe that as we examine the evidence and the artifacts, and they (as we say) "are taken in the light most favorable to the people" there is a very strong circumstantial case for the TIGHAR theory. And personally I think we are entitled to interpret the evidence that way. If someone else chooses not to, that's okay too.

The Electra wasn't AT Howland at 6:15 local. The Electra didn't arrive until 7:42 local at least by AE's belief. An hour and a half earlier the Electra would have been somewhere about 175 or more miles west of Howland. I estimate that based on an overall ground speed given the flight time of 19.2 hours and the distance traveled. It would have been shortly after that they saw the sunrise but we can't compute that exactly as we don't know their altitude or ground speed at that particular point in their flight.

Well, I'm not looking for any huckleberries, nor do I think you are one, but maybe a "defense attorney" to my role as "prosecuting attorney" would be a better description. Anyway, what you provided is indeed a clear explanation of your view on the matter, that's what I was hoping to see, and so I have a few comments. Regarding the dado and aluminum skin, you are right that they cannot be traced to any specific aircraft right now. By themselves they are not proof of anything. They might be from AE's aircraft, they might not. You say that there is no indication that the aluminum was ever attached to an airplane. I thought (and maybe Ric could jump in and clarify) that there was some wording or code stamped on the aluminum skin that indicated it was indeed aircraft aluminum, that it was aluminum that could not be used for any other purpose. You say "No such aircraft were lost on Gardner, so we know that the bookcase came over in a boat. Without affirmative proof contra-wise, Occam's Razor compels us to believe that ALL aircraft wreckage on Gardner arrived the same way". Sorry, I can't agree with this at all. While it is possible that all aircraft wreckage on Gardner came over in a boat, I don't think it makes sense to rule out other possibilities, such as an aircraft landing or crashing on Gardner. Your argument is that bookcase came over by boat, therefore all artifacts came over by boat and I can't agree with that at all. I can think of other possible and likely mechanisms. Now as far as your other points, my view is that the aluminum skin and dado must be viewed in combination with all the other evidence. They do not stand by themselves as proof of anything, but the fit in a pattern of evidence that includes artifacts, Ric's recent posting on post-loss messages, a castaway on Gardner, a skeleton found with a sextant box and woman's shoe, etc. Perhaps that's where we differ. If we have to proove each and every artifact and other piece of evidence DEFINITELY comes from AE, then I suppose we will never get there unless you find the Electra. I look at it just the opposite, that the totality of the evidence is unlikely to have come from any other source, that AE landing at Gardner is the most likely solution, and that other solutions require many, many unlikely and random coincidences.

TR #2427 ========================================================================= Date: Fri, 20 Dec 2002 11:38:34 EST From: Mike Everette Subject: Betty's radio For Gary LaPook Gary, I think you may still be missing my point. The receiver Betty used, whatever type it was, had ONE IF frequency... not two. It was single conversion. The IF was in the vicinity of 455 or 465 KHz. The IF amplifier had two stages, two tubes/three tuned circuits. The two-stage IF would provide a definite boost in overall "gain" through the receiver (ability to detect weaker signals), and additional selectivity against adjacent-channel interference from signals near the frequency of the desired signal... but the number of IF stages does not protect against images. of course. That is the job of the tuned circuits and amplifier stages at the signal frequency, the RF Amplifier stages... ahead of the IF. The Zenith Strat had 2 radio-frequency amplifier stages operating at the signal frequency, which would have provided a high degree of front end selectivity and image rejection, but would not eliminate ALL images especially those resulting from strong signals. The Crosley radio I mentioned had one RF amplifier stage. RF amplifier stages provide gain, to be sure, but not nearly so much as those in the IF amplifier. The function of an RF amplifier is more to isolate the antenna from the mixer/converter stage, and screen out images, than to provide gain. The amount of isolation, screening, image rejection or whatever you call it, is dependent less upon the number of RF amplifier stages (number of tubes) than upon the QUALITY of the tuned circuitry in the antenna input and RF amplifier stage. Some radios are much better than others in that department, obviously. Again, the radios under consideration and discussion are all SINGLE CONVERSION types. Only one IF frequency. This discussion might be better conducted off forum... I think Ric would agree, this really isn't supposed to be a radio theory course.

Don't get bogged down in Scott cabinet designs as these sets were sold as a chassis, amplifier and speakers and were installed into all kinds of cabinets by their owners, including cabinets that were originally made for other radios.

I thought (and maybe Ric could jump in and clarify) that >there was some wording or code stamped on the aluminum skin that >indicated it was indeed aircraft aluminum, that it was aluminum that >could not be used for any other purpose. 2-2-V-1 (the section of aluminum skin) has been identified by the National Transportation Safety Board laboratory by means of conventional and scanning elelctron microscoptic inspection as being 24ST ALCLAD - a type of aluminum most often, but not exclusively, used in aircraft construction. The aluminum sheet has remnants of the original manufacturer's (Alcoa) labeling which has been identified by Alcoa by the content and the particular font used as labeling the company employed in the the mid-1930s (but not during WWII) on sheet aluminum approved for aircraft repair, but not original construction, use. The surviving rivet is an AN455 AD 3/3 "brazier head" aircraft rivet that was in common use in the prewar years but was replaced in most applications by the AN470 "universal head" rivet in 1940. The pattern of rivet holes in the sheet exhibits pitch and spacing of a precision that is required in aircraft construction but is not common in other applications. Many people have questioned what airplane the artifact may have come from but no knowledgeable person who has ever looked at 2-2-V-1 has questioned that it was once part of an airplane. Maybe it's not, but "there is no indication that the aluminum was ever attached to an airplane" is the kind of comment that gets us in trouble for ridiculing our critics. Rich Young says: >Without affirmative proof contra-wise, Occam's Razor compels us to believe >that ALL aircraft wreckage on Gardner arrived the same way". And it's statements like this that prompted us to include an explanation of Occam's Razor in the FAQ section of the website at http://www.tighar.org/Projects/Earhart/forum/FAQs/razor.htm By the way, the dado was similarly inspected by the NTSB lab. It's made of aircraft material, with aircraft rivets, to aircraft standards. Maybe somebody made a part for a boat that looks just like an aircraft part and just forgot to put any kind of corrosion inhibitor on it - but it seems more likely that the thing is what it appears to be (but not because of anything Occam said).

John interviewed Olive circa 1970s. Knowing that this question had been raised on the forum, Betty phoned me yesterday to explain why her mother told John it was a Sears and Roebuck Silvertone set.

Betty's sister moved back to the St. Pete area and Betty's mother found herself homesick for Florida, so once more they sold up and moved back across the country, outfitting their new Florida home with new furnishings. Betty tells me that in her mother's mind it was as if they had never left and so when John talked to her in the 1970s she described the radio that had replaced the Zenith. >Reportedly, Betty had two sisters, one of whom you point out died in 1999. >Can you ask Betty if that was the sister who arrived home with the father and >heard part of the transmissions?

I also suggested something similar which met with a less than enthusiastic response. As I understand it, Ric thinks that because the ionospheric conditions would be different (as would the extraneous interfering radio traffic), it would be a pointless exercise. This most recent sunspot maximum has been pretty similar to cycle 17 of 1937. By the time of the next expedition however, conditions will not be so similar. However, I think there are excellent reasons for doing it. If we can copy the design of the WE transmitter - preferably using paper capacitors, original type transformers etc and anyone in the US can pick up a transmission from Niku (with probably less favourable conditions), that will at least tell us it was perfectly possible over that route in 1937. We might also learn something about the particular harmonics radiated and their power. I do in fact have a friend who has the very same transmitter, but I doubt he would let it free of his clutches for such an experiment. It would however make the transmitter much easier to copy. If Tighar were prepared to fund the components, I would be prepared to build it. Fortunately I also have a friend, Steve Harris, who was until recently the proprietor of the Chester radio museum, a large collection of sufficient importance for the BBC to buy the whole thing lock stock and barrel to create a national museum. Consequently he has excellent contacts for parts. Quite apart from any information we can derive from the exercise, I think it would be immense fun for forum members. As things are, when the expeditions depart, forumites are somewhat left on the sidelines until the expedition is over. This would be a great way of allowing everyone to participate in the expedition. Their main cost would be a suitable (ancient or modern) shortwave receiver. Modern receivers of better quality than Betty had are now very cheap. Cruising the dial at dead of night listening for Ric's(?) dulcet tones amid the howlers and static, might not be everyone's idea of fun, but you can't deny it would be novel. Funds could be raised direct from the forum. I suggest that those who want to participate could be asked to send (say) $20 for a copy of the transmission schedule. 50 subscribers would raise $1000, but whether this is a realistic figure for the cost of the parts, I have not the least idea. If there were enough subscribers we could even have some prizes for the furthest/most intelligible interceptions. I suggest that those who would be interested in principle send a single line e-mail to the forum for us to see what support there is for the idea. If Ric can be persuaded to go along with the idea, I could do some research to find out how much very roughly, it might cost. Regards Angus. ************************************************************************** From Ric Angus, with all due respect, before you start designing fundraising programs for TIGHAR you might consider joining the organization yourself. My opposition is philosphical rather than practical. I don't think that recreations accomplish anything useful in historical investigations. Thor Heyerdahl went to enormous lengths and considerable personal risk to "recreate" a theoretical Pacific immigration that subsequent archaeological research has pretty conclusively shown didn't happen. It might be fun to try to send messages just like AE might have but I can't imagine that it would prove or disprove anything. More importantly, success or failure would tend to influence the way people viewed historical evidence and that could be actively harmful to legitimate research.

Surprisingly, it would have to have been for the Howland to Lae leg on the original flight plan, but with no navigator aboard (Noonan was to have left the plane on Howland) and with tail winds, perhaps less fuel would be necessary. The Avgas was delivered prior to the first flight. Some was used by the graders for construction of the runways, but I believe they only used one drum.

She also researched much literature, documents, data, etc. As for any research on any subject, the researcher should consider all sources, and then evaluate them.

Then, anyway, as i think of it, you would want to simulate the aerial on the coral flats, and do this for best and worst case orientation, considering radiation pattern favoring USA. That's 2 antennas. Then, a few nites try wouldn't do it either: i think maybe something like 100 days trying. Oh- and then there's the permit from the FCC to do this - you COULD get by without it, but without some legal sanction to transmit, the operation might be under a pall, and you maybe couldn't get volunteers to listen for it. Of course, if there was too much publicity, you can be sure the jammers and hoaxers would be in there too. Myself, i don't see that it has yet even been established that AE's transmitter could do this. I don't see that it has been established what power the transmitter output at each practically possible harmonic, and then how much that initial power was decreased by another hurdle, the degree of mismatch to the antenna.

The entire >opinion-research industry is devoted to translating possible outcomes (Do you >intend to vote for X or Y?) into probabilities (Our polls show X has a 60% >chance of winning the election). I think you are confusing a basic probability concept. In the case of Betty listening to a broadcast, Bob Brandenburg is 100% correct, the probability that it was Earhart is 0% or 100%. No other possibility exists. In the case of opinion polls which you cite, the probability comes from the fact that we have multiple voters being asked a question, and a fraction of them respond with one answer and another fraction responds with a different answer. This does not lead us to conclude, as you say, "X has a 60% chance of winning the election" ... it is that X has 60% of the resondents in the study voting in favor of X. The wording is an important difference. X will either win the election, or he will not. His probability of winning the election is either 0, or 1. Back to listening to radio waves on some afternoon in July 1937. Here's an experiment we could never perform, but think of it as a "thought experiment" to illustrate a point. At randomly selected locations throughout the United States, listen to the same frequency as Betty at the same time as Betty. We would find out that at z% of the those locations, we hear the same broadcast as Betty. How that helps? I don't know ... other than to illustrate the point that it gives us no information about whether it is Earhart or not. It either is Earhart or it is not. >However, since Bob declined to qualify his opinion in terms of probabilities, >I assume that his level of certainty is near 100%. In that case I would like >to know how he determined the voice "Betty" heard was that of Amelia Earhart. I think Bob did answer the question. I disagree with your assumption.

Additional sun shots will only give Noonan more lines running generally in a NW/SE direction and certainly would tell him if he is going further east or further west but his north/south component will need to rely on something other than the sun shots.

Unless someone can show me how the different probabilities can be practically used I'll stick with either she did or she didn't." Alan, I guess it all depends on how you define "practical use." To me the probability that Betty heard Amelia Earhart is absolutely relevant to the authenticity of her notes. If that probability was, say, 10 percent, then by definition it is far more probable than not that Betty actually heard something else. In which event the search for what that "something else" may have been gains added impetus. In the final analysis it boils down to how the inquiry is structured. Your question is, "Did Betty hear AE or did she not?" Mine is, "What did Betty hear?"

Gary I think your explanation can be simplified somewhat. A bubble sextant does not need a correction for Dip or Semi-diameter. Ref: Nautical Almanac (mine is the 1988 edition) Under Explanation of Altitude Correction Tables it states, in part, "When using a bubble sextant no correction is required for Dip, Semi-Diameter.........." So I think only refraction would be required. I believe it is generaly accepted that F/N used a bubble sextant Jack Clark. ========================================================================= Date: Sat, 21 Dec 2002 09:25:38 EST From: Hue Miller Subject: Re: harmonics vs. ham frequencies Mike Everette wrote: > I am thinking in terms of all possible harmonics which this transmitter > might generate.

We need to concern ourselves only with multiples of 3105 and 6210 that are in the approximate 15 - 21 MHz range, well, maybe up to 25 MHz or so. Explanation in following paragraph for circuit heads. Hue Miller [The crystal oscillator was followed by a bandpass circuit, which was designed to pass only a certain range of frequencies. At least, this is the way the circuit is described in the technical literature. That range would include only the possible "working frequencies". The output stage was the harmonic generator - but the radiation of harmonics over any useful range depended on the working in concert of the output stage *and* the particular antenna characteristics at each possible harmonic frequency. ] ========================================================================= Date: Sat, 21 Dec 2002 11:08:21 EST From: Angus Murray Subject: Re: Radio transmissions to forumites.

This was a suggestion for you to take up or not as you please. And with all due respect, whether one contributes to Tighar via research and contributions to the forum or by financial means seems to me neither here nor there. I did also offer to build the thing without expecting anything for my time. I also spent considerable time helping you identify the lead spout and reassessing the wreck photo by a photogrammetric analysis which you agree shows it to be a hoax.

Again I spent considerable time assessing the brass screws for country of origin and the aluminium catches. However, you are obviously more nettled by the fact that you haven't actually got any money out of me than you appreciate my contributions. I also don't agree with you that historical re-creations achieve nothing. Museums are full of re-creations which let people better understand what they cannot easily imagine. That does not mean that archaeologists frown on re-creations because they might be inaccurate. Anyone with half a brain knows that re-creations can be wrong. If Heyerdahl had discovered that the current ran in the wrong direction, it could have sooner improved understanding of migration patterns. But in fact he showed was that it was technically possible and not to be discounted. So what - it did not prevent anyone arriving at "the right" conclusion. What is the Tighar Hypothesis if not a re-creation? According to your ideas, such a mental re-creation should not be allowed either because it can produce errors - such as connecting AE to the shoe heels found. >It might be fun to try to send messages just like AE might have but I can't >imagine that it would prove or disprove anything.

I think you are getting things out of proportion. If anyone "viewing historical research" had their perception of events positively or negatively influenced that would be their own problem if they were sufficiently dim to see that it is impossible to re-create the same propagation conditions as existed in 1937. If Tighar, on the other hand would prefer not to see such an experiment, that in itself shows a bias because if no-one detected any message it might be seen (erroneously) to weaken the Tighar case. However, who would know anything about it unless it is made public? Anyone reading this forum, on the other hand, would see that Tighar, at least, does not regard a positive result as meaning anything other than, given the right conditions, such a DX is possible. Regards Angus *************************************************************************** From Ric Angus, I did not intend, and I apologize if I seemed, to imply that TIGHAR does not appreciate and value the research contributions you have made. If I could convince the phone company to accept good historical research in lieu of dollars in payment for the phone bill I'd also agree with you that "whether one contributes to Tighar via research and contributions to the forum or by financial means seems to me neither here nor there." The fact is, the entire project is based upon the premise that interested people pool their resources - both mental AND financial - to work toward a common goal. It's important that researchers become TIGHAR members. Very important. All the individual research in the world is of little use if there is no central clearing house and focal point to pull it all together, and so far, in the case of the Earhart disappearance, TIGHAR has been the only publicly open and accessible game in town. We understand that not everyone can make large financial contributions, but to stand aloof from even basic membership is to deny the context in which the research is carried out. And if anyone thinks that becoming a TIGHAR member necessarily implies an endorsement of TIGHAR's hypotheses and conclusions I need only point out that many of the harshest critics who regularly voice their dissent on this forum are dues-paying TIGHAR members. On the subject of historical recreations - I think it's a real stretch to call a hypothesis a recreation. In deciding what activities on which to spend our very limited resources we always try to focus on those things that have the potential for producing conclusive results, or least results that help move us forward. I just don't see how a radio recreation would do that. If we couldn't replicate Betty's experience would we then conclude that she must not have heard AE? If we did replicate it would we then conclude that she must have heard AE? Of course not. Bob Brandenburg has already shown that the reception was theoretically possible. Beyond that there's not much we can say. Reconstructing old radios, old airplanes, old voyages, old battles, and so forth is great fun, is often good theater, and can be an effective way to illustrate what is already known, but it doesn't give us answers and we are after answers.

Mine is, "What did Betty hear?" And how, I wonder, can we hope to answer that question? If Betty heard something other than a transmission from Earhart we could discover a diary or contemporaneous letter or even a deathbed confession from somebody who perpetrated the hoax (ala the recent Bigfoot revelations). In the absence of something like that we have to acknowledge that her reception of authentic transmissions from Earhart was possible (is there anyone so bold as to pronounce them impossible?) and that, so far, nobody has come up with an alternative explanation that is any less bizarre than the idea that she actually heard AE. So it stands as an enticing possibility that can be accepted or rejected as you wish. I would predict that with greater recognition that at least some of the post-loss signals had to be genuine, and with mounting evidence that the Electra landed at Gardner, there will be a greater acceptance of Betty's, and possibly other amateur listener's, accounts. But even so, unless we discover AE's diary buried in the sand in which she describes sending the calls that Betty transcribed, it's hard for me to imagine how we'll ever have proof of what Betty heard.

There is a world of difference. I beg to differ, Pat, Lovell's book is a very well researched biography that depends on much more than mere personal memory and anecdote. Please refer to the 42 pages of endnotes at the end of her book in which she cites her sources, many of which are original documents. I, too, read Ron's comments as viewing The Sound of Wings as a well-written and well-researched book, nothing more. David Evans Katz ************************************************************************** From Ric I don't think there's as much disgreement here as there might appear to be. I think we all agree that Lovell's book is a well-written biography. In fact, Pat and I think that it's the best of the Earhart biographies to date. I think we all also agree that it is not, and does not pretend to be, a research paper.
