In Britain, the Political Warfare Executive operated a number of black propaganda radio stations. Gustav Siegfried Eins (GS1) was one of the first such stations â€” purporting to be a clandestine German station. The speaker, 'Der Chef' purported to be a Nazi extremist, accusing Hitler and his henchmen of going soft. The station focused on alleged corruption and sexual improprieties of Nazi Party members.
Another example was the British radio station Soldatensender Calais, which purported to be a radio station for the German military. Under the direction of Sefton Delmer, a British journalist who spoke perfect Berliner German, Soldatensender Calais and its associated shortwave station, Kurzwellesender Atlantik, broadcast music, up-to-date sports scores, speeches of Adolf Hitler for "cover", and subtle propaganda.
There were British black propaganda radio stations in most of the languages of occupied Europe as well as German and Italian. Most of these were based in the area around Woburn Abbey.
