Hi Its good to hear about all of these issues. I have the same issue as the last post. I went through a new set of cables, new kat500 board, and tons of trouble shooting with Elecraft. Happens the same on two completely different antennas each with completely different feedlines. The solution is not there yet. There is perhaps an issue with hardware updates on the kpa500. I have an early unit that is about 2years old. I haven't yet decided if I will send it in or live with it. In my case it happens on many bands and every time I switch to a new frequency even though the kat had already tuned there. Tom

It corrects itself if I continue talking, but it is annoying. I have firmware 1.42 loaded in the KAT500.
