John-
I worked SS contest last night (SSB) and had a similar problem
running at 100+ watts with my K2-100 and the KAT tuner. I had a
difficult time getting a match when in high power (anything above 11+
watts). When I transmitted, the KAT-100 would switch to "Ant #1" for a
second before switching to "Ant #2" which is what I had selected (#2).
#1 is my tri-band beam and #2 is my 135' dipole fed with open-wire
feedline with a 4-1 balun near the KAT-100.
I tried tuning at low power (10 watts or less) and everything
worked as designed, even if I then cranked the power to 100 watts. So,
when I would change frequency, I'd power down and tune for a good match,
then power up and the problem disappeared. Seems the KAT-100 wants to
tune at low power first...if I do high power first, I got the antenna
switching and high SWR that you did.
I can't explain it, I'm just glad I stumbled onto a solution
because it was mighty frustrating - I even, perish the thought,
considered putting my ICOM 706 MkIIG on line!
