Also agree, everyone brags so much on the K3 QSK that I thought it was just a problem here. I have almost stopped using it because of the "junk" created when keying with any signals nearby. Merv K9FD/KH6 I agree with Vic. QSK is sometimes painful. CW Exuberantly, Hank, W6SX On Tue, Nov 1

I know I might be beating a dead horse, but my recent experience in big, noisy pileups has made this problem stand out. The t/r transitions in QSK and semi-QSK CW when there are nearby strong signals make a horrible racket -- enough to make me turn down the volume when sending, which negates t
