PRC-1 Restoration

This radio was used by US Military Intelligence for clandestine operations in Europe. Contrary to some literature the PRC-1 was NOT used by the OSS. They did obtain several units for evaluation but were not used operationally due to its power needs and the fact that a single unit made concealment and transporting difficult. It weighs 32 pounds and is 18 x 13 x 17 (approx). transmitter is a 6V6 oscillator/driver and 807 final. Receiver uses 6SG7, 6SA7, 6SK7, 6SL7, 6J5. Coverage is 2-5 & 5-12Mhz. 30 watts CW.

Empty suitcase in bad shape. I suspect this suitcase will be discarded and an
equivalent manufactured.

Bottom of suitcase - ouch!
