Kev,
For your indication of high SWR when the KPA500 is in OPERATE, try
replacing the coax jumpers with known good ones.
It is not unusual that a coax jumper (or antenna feedline) to seem to
work at lower power, but can breakdown at higher power levels,
particularly from a shield that has almost pulled away from the plug.
Also, make certain the PL-259 connectors are tight - snug them down a
bit more with pliers.

Thanks everyone for helping me understand the right way to use the KAT500.
I could have sworn I was doing the right thing by keeping it in auto. In
fact, that's how it has been setup up since day one here. I'm hoping that
didn't contribute to my KPA500 problem.
