[Milsurplus] GA Radio Transmitter

[Al Klase]

David,

A little bit here: http://earlyradiohistory.us/1963hw23.htm

" After the laboratory was moved to Anacostia, its staff was increased 
by several radio engineers and it was assigned the additional functions 
of design and development of complete aircraft radio systems. Two 
transmitters, the SE 1375 and SE 1385, which later became the backbone 
of naval airborne communications, were designed and developed. Both of 
these produced a clear 500-cycle note and neither was voice modulated. 
The SE 1375, 20 watts, which used four three-element tubes and operated 
on frequencies between 570 and 750 kc., was designed by Mr. F. B. Monar 
for use in small aircraft. The SE 1385, 500 watts, which used two 
50-watt three-element tubes and covered the frequency range, 300-600 
kc., was designed by Mr. L. A. Gebhard for use in large flying boats. 
One of the first radioteletype transmissions from aircraft to ground was 
made utilizing the SE 1385. It also became the transmitting component of 
the first aircraft radio transmitting system given a model designation, 
the GA. "

73,
