Amusing image though this is, Enigma machines were, in case you weren’t aware, not actually radio transmitter/receivers.

An enigma message would be typed in to the machine and the output characters written down on a piece of paper, then the message would be transmitted over Morse by hand, transcribed to paper at the other end, then typed through the correspondingly configured Enigma machine to obtain plaintext.

I have enough trouble typing things I mean to say without trying to transcribe line noise. That sounds like a terrible job.

In absolute terms, pre-digital cryptographic equipment operator isn't the worst wartime job I can think of. However, on a U-boat, all of the jobs were equally worse (due to life expectancy).
