I do hope that you noticed that in addition to a link at the top to the source of that chart, that I had also provided a link below "This report discusses each of the eight Bearings" and that report with several pages on each bearing discusses all of the problems you have posted and more.
Over 50 pages in that report and I advise anyone with an interest to spend some time to read it. I see that Gary has a link to a different report and perhaps it is a simplified version of the same as it is only 10 pages.
Art,
Yes, I did take note of your link.
If you go to the beginning of the RDF report version that Gary linked and compare the report in its entirety to the version that you linked, you’ll find them to be effectively identical in length and content.
One point of my last post was that if one has source material at hand—whether it’s for lines drawn on a map or for assessing someone else’s conclusions—it’s a good idea to read the source material before drawing your own conclusions about meaning or content.
BTW, additional RDF-related material is accessible from these links:
DF site tables
Pan Am Memos

Chuck,
Thank you for your response and your links to further information.
It had been after my last post that I read Gary LaPook's link and of course soon realized that way beyond just the ten pages I had first glanced at, that it contained links within to seven more sections.
It is actually a much easier read than the one I posted a link for, as it not only has all of the text that my link contained, but is more logically laid out with all those graphics seen on the pages with the discussions. As long as it was, mine was sort of a condensed version (lacking most of the graphics).
Also thank you for the link to those Pan Am Memos, it had been a long time since I had read those.
It would probably be best for a reader to
look at the Pan Am Memos first, (your link) and then
go to Bob Brandenburg's exhaustive analysis of RDF bearings (the one from GL's link).
I certainly agree with you that in order to form an opinion on
RADIO DIRECTION FINDER BEARINGS (your link to the Large version)
that they should be approached within the context of the above 'Memos' and 'Analysis'.I do think that the above information adds greatly to the TIGHAR hypothesis and should not be rejected outright for the reasons Gary LaPook mentioned.
The poor signal qualities at those Pan Am HF/DF stations should certainly be expected under the circumstances.
I agree that if they had just added some 'dots' to go along with the 'dashes' that were heard as Gary pointed out would have been so simple to do, we probably would not have this marvelous mystery at all.
Since they evidently were hearing those Honolulu Radio Station KGMB broadcasts requesting the plane to transmit four long dashes on 3105 KC, perhaps KGMB could have requested some 'short dashes' in a Morse Code format along with those long dashes that were being copied. If they were able to transmit a 'carrier' for two hours, as Gary mentioned they could have included a lot of 'code' in that time.
It seems that the small amount of "poor" code that was copied, (by other than the Pan Am Stations) was mostly just gibberish and the only 'voice'
that was copied did not reveal much about location either. There were anecdotal stories of receiving position information that was recorded and then lost long ago.
No one knows what their mental (or physical) condition was at that time.The only hope I see to completely resolve this portion of the mystery would be to find a miraculously preserved copy of a detailed log or diary or something somewhere....
As Malcom indicated
'few of us believe in miracles' 
but that just
might be possible.
