The SST-1 Transmitter is a unit of the SSTR-1 “Suitcase Radio”, a clandestine radio for use by Office of Strategic Services (OSS) agents in WWII. Because of the radio’s small size, OSS agents had a good chance concealing it on the streets and fields of battle. In enemy territory, undercover agents could transport this component inside a loaf of bread, quickly set up, transmit a message, then break down the radio and move away before enemy direction-finding equipment closed in on them. This cutting edge technology, rehearsed in the forest of what would be called Prince William Forest Park, helped win the war.
