I would guess that you have a piece of coax and/or connector going bad.
Will be something common in the path from amp to antennas, including a
remote coax switch. Something is arcing

Cables and connectors are forever going bad. Especially the ones we've used
forever and just keep reusing because they're a convenient length. Most
likely something mechanical, too much bending for too many years, etc.

[Elecraft] One problem solved. A new one appears.

I solved this by plugging in the cables one at a time. All utilities working 
fine now.

New problem:

On 6 meters, with the input power to the KPA500 around 7 watts, I get 200 watts 
out. But as I increase the input power, the SWR increases and a “hi swr” fault 
occurs. This happens with 3 different antennas: a 3 el beam, an R8 vertical, 
and a dipole. All are tuned to low swr via my KAT500.
I have tried connected the beam directly to the KPA with the same result. 
This only happens on 6 meters. It used to work fine when I had a K3. I now have 
a K3S. Is there some setting in either the K3S or the KPA that I should change?
