Like to help, but comms has moved on for me too, as I was a WoP
(Telegraphist) in the 70's Trained at RAF Cosford, using then Morse
up to 20 words a minute, I think it was and typing to work the the
teleprinters & TASS. Can vividly remember the relay stations,
the Murray tape, the Morse logs, the Bids, chaff. Did from 74 to 80
and Satellite was just starting to come in by then.
