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 .
