< I just read, with great interest, an article in the April 1998 issue of
CQ magazine, about the WORLD (last) flight of Ms Amelia Earhart and Mr.
Fred Noonan in 1937, not the least was the removal of the C.W. key (to
save weight) because both she and her navigator, Fred Noonan, disliked
working C.W." (read neither were competent C.W. operators)
and
Mr. Bill Orr W6SAI goes on to report: because the removal of the trailing wire
antenna (with it's motor driven reel, which is an antenna tuner, the length
played out sets it's resonant frequency) left only a fixed length "V" antenna
running from the tip of each (of the two) vertical fins (rudders) to a post
mounted near the front of the plane, an antenna that worked so poorly that on
3.105 MHz their 30 watt transmitter delivered only about 1/2 watt and on
6.21 MHz only about 3 watts (due to mis-match and loading coil losses) to
the antenna.
I doubt they would leave the CW equipment behind, then try to work cw with
the am equipment.
