If the problem is present with the K3 (without the KPA500) set to 50 to
100 watts, then the KPA3 is the likely problem.
BUT if the K3 operated up to 100 watts does no have the problem, look
for an RF in the Shack problem that may not be apparent at 100 watts,
but 'rears its ugly head' at 500 watts output.

A local ham had the exact same problem. It was not a problem with his setup.
Elecraft replaced the PA board and the problem went away.BruceKS4V

I ran my KPA500 for several years at 500w and often received unsolicited “great
audio” reports. CM500 was my headset.
