[Milsurplus] Looking for Bendix info

[Robert Nickels]

Realize it's a long-shot, but I wonder if anyone knows anything about a 
Bendix Communication System used in aircraft.  It's from the era when 
planes transmitted low-power AM in the HF range and received either on 
HF or on the beacon band.   The unit I picked up is labeled model 3801 
Bendix Communications System (N. Hollywood CA), and consists of model 
3103 Receiver and model 3006 Transmitter in a single housing.  The 
receiver tunes 2.5 to 6.5 mc plus 200-400 kc, and the transmitter has 
three crystal positions, a built-in antenna tuner using a roller 
inductor, 12KS7 oscillator driving a 1625 final.  What I have is 
basically the RF sections of the transmitter and receiver in a small 
enclosure about 6" by 6" by 12".  Receiver audio stages, BFO, (and maybe 
more),  plus the modulator and power supply was remotely mounted and of 
course I didn't get that unit.

Looking for documentation of any kind, as it's going to take some 
head-scratching to figure out the proper interconnections and functions 
that were off-loaded to the remote unit.   I'd appreciate any 
suggestions as to where I might even look for information on old 
aircraft radios, as this is the only one like this I've ever seen, and 
web searches come up empty.  Still, it would be fun to make it play on 
80 meters some day.

I've uploaded some pics here in case anyone would care to take a look:
