[CW] AR or K after CQ?

Hi Ron

Normally one sends K at the end of a CQ to indicate your listening for any station to reply. Then one should listen for at least the
length of the CQ message given in case of QSB or poor band conditions.

 You can send AR K but it is not necessary to do so. 
You would be saying:
AR 'end of message' (the CQ message)
K 'end of transmission' listening

Nothing really wrong with either or both but given together they are sorta like double talk, which some regard as a waste of
bandwidth and therefore LIDish.

In my humble opinion the one everyone can leave off is the 'PSE' that seems to be gaining in popularity with the automatic sending
applications that are popular. 

It actually began with PSK not CW and to me is a knock off of someone sending with an application rather than a keyer. I normally
dont respond to those, just from my own personal desire to work a station who is working a key. 

Not trying to be elitist here, I just like the sound of human CW, it tells you a lot about the personality you are talking to.

AR is 'end of message' 
SK is 'no reply necessary' 
K is 'end of transmission'
KN is 'end of transmission listening for only station in QSO'

Sent with a ? any of the above are asking a question of the recieving station of the same defining characters.

Doesn't really matter, as long as the CW is pure, which is not consistent it seems these days for the most part on the bands.
