On Friday 7 April 2017 the amateur radio station DLØHNF transmitted an Enigma encrypted message on 7036 kHz to Bletchley Park
DLØHNF is the club station at the Heinz Nixdorf Museum in Paderborn, Germany. The encrypted telegraphy message they transmitted was received at the home of the World War Two UK Codebreakers in Bletchley Park. There the message was fed into a replica of the Turing Bombe which enabled the encryption to be cracked.
The message read: “Paderborn greets the Codebreakers at Bletchley Park"
