Sending a message to Bletchley Park

In his blog, Tim G4VXE reports on the encrypted messages sent from Cheltenham to Bletchley Park to commemorate the 100th anniversary of the birth of Alan M. Turing.

In Cheltenham messages were encrypted by an Enigma machine (owned by GCHQ) and sent to Bletchley Park using morse code.

Tim listened in to the morse traffic between Cheltenham and Bletchley Park (GB5AMT and GB2BP respectively) on 7035 kHz and asked via Twitter if he could send his own message which the Cheltenham station agreed to.
