British propaganda radio station Deutscher Kurzwellensender Atlantik began broadcasting to German submariners.

The Deutscher Kurzwellensender Atlantik, was a British propaganda radio station operational during the Second World War. The station was the idea of the Political Warfare Executive's Sefton Delmer and broadcast from the Aspidistra in Sussex, England, between 1943 and 1945. The radio station's transmission signal was strong enough to be received in all the Atlantic Ocean, and thus reach its intended audience, German submariners. The station broadcast popular dance music sourced from Germany and the US, as well as detailed news from Germany. 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.
