[Elecraft] K3 and QSK

[Graham g3tct]

I'm very interested in this topic, having raised this question a long 
time back.  What I said in June 2011 was:-
/I'm using qsk on cw and I find that if the rf gain is turned up to hear 
some background noise, there's a transient or click when the rig 
switches to rx (but not when it switches from rx to tx).  To hear this 
really badly, try opening the cw b/w up to 2kHz and sending a stream of 
dots. The effect is there even at 400Hz, and it's rather off-putting. /

It related to the barefoot K3 in normal break in, not QRQ.  I am 
referring to use on 6m where the background noise is relatively low, but 
signals can be very weak.  I do not have this problem with my other rig 
- an Icom 575.  It would be great to make the K3 as good, because I 
found it so bad that I have stopped using QSK altogether.
