Deutscher Kurzwellensender Atlantik

Atlantiksender focused primarily on aspects that would tend to reduce the morale of the submariners in the Kriegsmarine and to try and convince them that the Allies knew everything about their daily and overall military operations and strategies.

Deutscher Kurzwellensender Atlantik was led by Sefton Delmer, the Daily Express's former Berlin correspondent, for the British government's Political Warfare Executive (PWE).

[2] To achieve this, some of the staff were German defectors, including Otto John, Richard Wurmann, Hans Walter Zech-Nenntwich and Wolfgang Gans zu Putlitz.

[2] Delmer sought recruits from prisoners of war (POWs) held in Britain as these men would have knowledge of military jargon, operating procedures, and the concerns of the German sailors.

[1] A former bookseller, Frank Lyndner, kept a database of personal details taken from German prisoner-of-war letters to allow the station to announce births, deaths and marriages, transfers, promotions and medals relating to the U-boat service.

Fluent German speaker and later BBC journalist Charles Wheeler toured POW camps to gather personal stories about bars and brothels to include in broadcasts.

[1] To make the station attractive to listeners it broadcast the latest in popular dance music, under the direction of head disc jockey Alexander Maass.

[1] In one instance, British intelligence noticed an increase in German naval activity in the Gironde region and guessed it might involve an attempt for vessels to break out to the Far East; this information was passed to the station, which played a special programme of Japanese and Chinese music.

[10] The station broadcast an appeal to the U-boats to "Schluß zu machen" (put an end to it) on 29 April 1945, in the final days of the war in Europe, but this was unsuccessful.
