This morning my K4KIO antenna iced up without my noticing it. When I started transmitting I got a high SWR fault on the KPA500. I checked the SWR with my RigExpert analyzer and indeed there was high SWR on all frequencies.
I hooked the KPA500 to my dummy load and where I used to get a good 500 W with 20-25 W drive I now only get about 400 W with 50 W drive. Any ideas about what is going on? Did I lose a transistor in the final?
