[Milsurplus] AN/FRC-6A

[gl4d21a at juno.com]

The photo of the FRC-6 shows a rebadged Motorola FSTR-50 FM base 
station.  30 - 40 MHz, 50 watts, 15+ kHz swing FM.  The FRC-6A might 
be one of two possibilities.  Either the next frequency Range 40 to 
50 MHz or the next later model Motorola 30 to 40 MHz station.  I 
suspect the latter, since Signal Corps systems of the time generally 
did not go above 40 MHz.  Look for Motorola manuals of the 40s and 
50s.  Anyone in the early ham repeater business in the 50s and 60s is 
a likely source, or any old Motorola two way repairman can likely 
draw the schematic and give you the meter readings from memory.  
The "Yellow Book" was a compilation of Motorola service manuals of 
that vintage, but beyond that name and the 11" x 17" size, I have no 
other good description of yhat book, and mine is gone.

My suspicion is the FRC 6 had Loktal tubes, while the 6A had 
miniature.  807s in the final.  Identical to the radios sold to 
hundreds of police, telco and other civilian users.

Fair Radio and Radio Era Archives both seem to list a manual for the 
6A.
