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) transistorised radio sets were developed. Some of these are listed below.
