ANNOUNCEMENT: ENIGMA Encrypted Broadcast

You might recall that last year KPH broadcast in Morse Code and Teletype format a message encrypted using the notorious World War II German encryption device known as the ENIGMA machine. The response to that broadcast was so overwhelmingly positive that we are planning on doing this again. Now, here comes the MRHS Cryptography Department Manager, Kevin McGrath/KM with details!

ATTENTION ALL INTERCEPT OPERATORS!

Crypto Transmission from KPH

The MRHS in cooperation with our good friends at the Cipher History Museum will send a coded message in 5-letter groups via the facilities of coast station KPH on Saturday July 22, 2023. The message will be encrypted using the famous Enigma code machine.


The Enigma was the Germans' most sophisticated coding machine for securely transmitting command and control messages via radio communications in WWII. It was considered so secure that it was used to encipher the most top-secret of messages.


All KPH listeners are invited to try their hand at receiving and decrypting the message. Certificates will be awarded for proof of successful decode, first to decode, and use of original or replica hardware.


You say your Enigma code machine has gotten a bit rusty? No problem, MRHS has you covered! Software simulations exist for the Enigma code machine. Click Here for an easy-to-use Enigma simulator. It is web-based, so no download is necessary.


For additional information on the Enigma please see Ralph Simpsons' Cipher Museum History site.
