[Elecraft] KPA500 Power In Digital Modes

[Nick-VE3EY]

This happened with my KPA500 until I realized that my Microham double-six antenna switch is only rated to max 30MHz.    The SWR was fine, but KPA 500 kept faulting on 6 with High PA DISS fault code.  Once i connected my 3el SteppIR directly into the amp, it works full steam on 6 meters.

"I cannot get my KPA500 to run more than about 200W on 6M without getting a PA DISS fault.  Temp is not even up to 60C yet."
