Yes, the army and other services did use high speed Morse even into the
early to mid 60s. I was a manual Morse operator, and the boys in the next
room had the auto morse. They received with the same equipment we did,
except in our case we used a Mill (all caps typewriter) and they had a paper
tape with ink recorders that ran along like this ____-_--__- etc. (looked
like squared off sine waves. The ops then sat and used the same Mills we
did, to transcribe into letters. Sometimes I wondered if I made the right
decision, passing manual morse copy at 30 wpm at school. The other guys
just had to pass 5 wpm and they knew enough to transcribe from paper. HI.
I cant speak for the power used in the transmissions, but back then 500 W to
1.5 KW were typical transmitters used at embassies and military stations,
and it was just straight CW keying.
Many governments in Africa and Asia, at that time, were still using Morse
transmissions of this type, in all types of diplomatic and military
transmissions. As Teletype became more and more available, it quickly
slipped out of favor, even tho TTY was slower in transmission times, the
messges got thru without the additional translatiions.
