[CW] AR

[David J. Ring, Jr.]

I agree with you, except I don't believe KN was ever used in NATO or Allied
Comms as it is left parenthesis in commercial and military work.

But all the rest were exactly right.

In millitary and commercial morse, AR was simply "end of message".

When we called a station, we sent NGR NGR DE NPLM NPLM K

We didn't use AR like the hams use, because we were telling the called
station to "go ahead" - I have always found this "ham use" to be strange.

But as I grew more familiar with history of what went before me, now I see
why QST was used by ARRL - because at one time it was used just like CQ is
used.  A type of general call.

We also used (rarely) the signal CP for a restricted (not general) call as
in:

CP CP CP NCU NCG NERK DE NPLM NPLM O K

This would be a restricted call to USCG ships and coast stations and ships
involved in Naval Mercast.  (I don't know why it would be used but I've
heard similar in my years.)

Hmmmmm.,

  AR  sent at the end of a transmission, does not mean the same a K or KN.

    AR - Means end of message, and end of transmission where you do not
expect the other end to come back.

    K - Means I am finished sending now, and looking for anyone to transmit.
(  CQ CQ CQ DE N7DC N7DC K)  Anyone can call.

     KN- Means I am finished now, YOU GO AHEAD.   ( ET3USA DE N7DC KN) No
           one else should call at this time.

These prosigns are clearly stated out in ACP-117, which is the bible of
professional/government communications used by NATO and many government
agencies around the world.  If you look up ACP-117, and ACP-121, you can see
a lot of info about all that, plus all the Q and Z signals which are used
(and many which I never heard in 32 years of being a communicator)
