Announcement: Enigma Encrypted Broadcast Event



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 August 30, 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 hardware is a bit rusty? Perhaps it has slipped a cog?
No problem, MRHS has you covered! Software simulations exist for the Enigma
code machine. Click Here

Crypto broadcast date, time and formats



The crypto broadcast will commence at 2000 GMT (1300 Pacific) on 30 August
2025 on all KPH CW and RTTY frequencies. The CW frequencies are (in
kc): 6477.5, 8642.0, 12808.5, 17016.8, and 22477.5. Upon completion of the
CW transmissions, the broadcast will be repeated on the KPH RTTY
frequencies. The RTTY transmission will be 170cps shift Baudot, 45 baud.
The RTTY frequencies are (in kc): 6324.5, 8427.0 and 12585.5.



Further Information



Full details will be announced in mid-August via a Special Bulletin to all
MRHS newsletter subscribers and on the MRHS website.
