It was mostly voice in the end - but morse was always handy if you had a poor signal. It also kept the Rupert's hands off the radio - they would always be chatting using first names, ranks, map-refs in clear etc., Which drove you nuts. They - the supposed "clever people" didn't seem to realise that a couple of k's away, were guys just like us - listening to every word - and working out exactly who was where! I don't think they use morse any more now though.
Why back to 7.62 - did all the airfix kit break - again? jb
