[CW] AR

[N7DC@cs.com]

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)

For example, long calls were often used because most hams did not have much in the way of frequency control - either because of crystal control or the vagaries of self-controlled oscillators. So operating "split" was the rule rather than the exception, and often stations in a QSO were hundreds of kc. apart. After a CQ, the CQing station would often tune the whole band, or a big part of it, listening for answers. It was therefore necessary for a call to be long enough for the CQer to intercept. Even if the answering station was fairly close to the CQ'ers freq, a long call could be needed because there was usually no way to know which way the CQer was tuning. The abbreviations LM ("low-to-middle"), MH ("middle to high") etc., came into some use for this reason.
