Collins Radio Company, Cedar Rapids, Iowa. Founded by Arthur Andrew Collins, W0CXX (1909 - 1987). In 1973 North American Rockwell took over (Rockwell-Collins).


At the era of no Internet an long ago before  VHF repeaters , the air companies used the HF bands to communicate  with planes and airports. Thus they used mostly at the states the collins radios for their reliability .
The 32S-3A transmitter was the develop of an HF broadband Transmitter.
Frequency coverage was 3,40 Mhz to 30,00 Mhz .

For Receiving they invent the 51S-1  receiver ..

Wasn't simple to communicate Airports and Airplanes at 60s . Collins Co made equipment, making that functional during years .
