here is a couple scans
It is critical to the Betty reception report that she was listening on 24,840, the fourth harmonic of Earhart's 6,210 transmitter frequency, because Brandenburg calculated that no lower frequency had any chance at all, nada, nyet, nien, rien, to make it all the way to Florida. And even for 24,840 Brandenburg calculated only one chance in one million five hundred thousand.
Thanks for those scans since they support my position that Betty did NOT listen to Earhart on shortwave on 24,840 kcs. In image.001 you can see the highest frequency listed is 21,550 kcs, nowhere near the almost 25,000 kcs that Brandenburg needed her to be listening on. This is from 1939 and is the same highest frequency that I posted from 1927, nothing changed.
Image.002 shows the type of music you might hear on short wave and, just as I said, they do not broadcast American "Top 40" popular songs of the type that Betty logged so it appears that she was not in the habit of listening to shortwave radio broadcasts. Even if she did she had no reason to be anywhere near 24,840 kcs.
