OSS agents operating behind enemy lines in Occupied France relied on compact clandestine radios to stay connected with Allied headquarters.
The SSTR-1 became one of the OSS's standard sets. Its transmitter, receiver and power supply could be packed inside an ordinary-looking suitcase.
German radio-direction-finding teams actively hunted clandestine transmissions, forcing operators to send encrypted Morse traffic quickly, shut down and move.
By 1944, OSS personnel were parachuting into France to work directly with Resistance networks ahead of and after D-Day and these radios were often the only link between those teams and Allied command.
