Rob,
You may have something in your antenna system that is arcing at high
power, but is working just fine at low power.

All has been fine with my K3 until today. The display is indicating
"High SWR" when I transmit on SSB. The KAT3 indicates a 1.0:1 match,
but the when I transmit the swr meter is high and I get the high swr
message on the screen. If I turn it down to 5 watts and send a tone
with Digipan, the swr is fine, but turn it up to 100 watts and the swr
is back up. Nothing obvious has changed, the antenna is 2:1 on my
analyzer with no tuner. If I bypass the antenna tuner, the bar graph
meter on the K3 shows about 2:1. But if I switch in the KAT3 and
tune, it indicates 1.0:1 but when I transmit it's high. I've swapped
coax jumpers between the radio and the antenna with no difference.
Thanks for any suggestions.
