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

announcement on 500), 6477.5, 8642.0, 12808.5, 17016.8, 22477.5 . Upon
completion of the CW transmissions, the broadcast will be repeated on all
KPH RTTY frequencies. The RTTY transmission will be 170cps shift Baudot, 45
baud. The frequencies are (in kc): 6324.5, 8427.0 and 12585.5
