I had a similar problem. I returned from St. Croix on Wednesday where I had antenna issues and had to use the ATU most all of the time. When I set up the K3 here in Ct. I noticed high SWR on 15 meters, where normally, with my steppir, there is no SWR. Shut off the ATU and everything was o.k. I literally Just finished resetting the ATU to bypass on all bands/mode and I saw your email..\

I was working my way slowly up the band calling stations and not retuning the ATU each time I called. Presumably because of the way the ATU stores settings per frequency which may not be correct for the antenna I am using now, every now and then I would cross a boundary to a new stored value and suddenly see a HIGH SWR warning and have to retune. After retuning the output was only 50W or so, but it recovered to full output after several seconds of calling. My guess is it's a product of the fact that a lot of things in the K3 are controlled by software, which does not want to make sudden changes to things that would normally be expected to remain constant. It's just one of the quirks of the K3 that you get used to. ----- Julian, G4ILO.
