[Elecraft] K2 QSK

[Ron D'Eau Claire]

I'm wondering where you guys use such incredibly fast QSK? I keep the delay
long enough that I am not bothered by noise, etc., except between words or,
perhaps at speeds under 15 wpm, letters. I find it incredibly tiring to
listen to all the racket produced by having noise, QRM, etc., blasting
through at other times.

If someone wants to break me, he/she can do so easily with a couple of dits
between words.

If it's someone on frequency asking QRL?, it does me no good to reply since
obviously he doesn't hear me. The other station in the QSO has a better
chance. 

If it's DX I am not on his frequency anyway, so I'm not bothering him if he
answers someone else while I'm calling.

If it's a response to a non-DX call in which the station I'm calling
answered someone else, obviously the other station didn't hear me calling
since he called at the same time so unless he's a LID it's very unlikely I'm
being heard by him. Besides, in that situation my call is short and will be
done with by the time the other station finished with call signs, so I'm not
going to QRM the transmission.  

Perhaps you find it useful in frantic contesting to avoid wasting the few
seconds to finish a call when the other station answers someone else?  Or
perhaps while running an 'endless loop' CQ hoping for a break from someone?
