British spy radio sets

During and after WWII, the UK was one of the main developers and suppliers of spy radio sets and receivers. During WWII, a wide range of suitcase and special forces radios were developed and many of these were dropped over occupied Europe. Some of them were dropped together with a (secret) agent, but others were dropped-off at night for use by resistance groups.


During the Cold War, development and production of suitable radio sets for agents and stay-behind organisations (also known as Gladio) continued. Initially these radios were all valve based (tubes), but as soon as transistors became widely available, a range of (partly) transistorized radio sets were developed.
