For those of you with a HAM radio (receiver) setup and an interest in crypto, the MRHS (Maritime Radio Historical Society) and the Cipher History Museum have an Enigma challenge this Saturday (July 22, 2023)

They'll be sending a coded message in 5 letter groups, which you can capture and then decode with the Enigma you have collecting dust on your shelf.  Or if you don't own the actual gear, you can use an Enigma emulator on your phone or an online simulator - those of course will do the job very nicely as well.

If you don't have a full HAM radio setup, you can do receive-only very nicely wiith an RTL SDR (software defined radio) if you have the right geography + antenna combination, so the barrier to entry on this is very low, as long as you are close enough to "hear" the signal.
