[Elecraft] KPA1500 reflected power faults

Is it possible that something is heating or arcing in the device you are
using to match your 43 ft vertical?

Hi, all,

My KPA1500 is throwing a lot of reflected power faults at power levels above
500 watts. The symptom is that the output power (as indicated by the power
LEDs) zooms up and then the amp faults. An external MB-1 power meter
indicates 2000 watts or more peak output when this happens.

I know the usual culprits (poor ground, RF in the shack, surge suppressors),
but I wonder if other owners are still having these problems, despite
attempts to fix.
