Don, I just ran full QSK test on 10m this morning, up to 70 wpm, and both the K3 and the Alpha 9500 sounded very good to me, after resetting TX DLY down to 08. However I'm not sure how it would sound on the other end. Hopefully today, if I don't get flooded out of here (6 inches of rain yesterday and more rain this morning!), I'm going to hook up my IC-7700 and listen for myself. I am quite impressed with what I hear via the K3's sidetone.

Pops in the K3 audio while keying an amp could be a sign of "hot switching" in the amplifier. Try increasing the keying delay in the K3 to see if that eliminates it. If not, check the relay "pull-in time" for the amp (plus any contact bounce time), and if it is not within the K3 Key-to-RF onset time, you will not be able to use QSK with that amplifier unless you can speed up its T/R relay. 73, Don W3FPR On 7/15/2011 8:42 PM, Tommy Alderman wrote: > Thanks to NV1B, K9ZTV,VK4FD, W3FPR and to Dick for the quick response.
