Richard,
Welcome to the world of high power. How do you have the radio
grounded? How close is the antenna to the operating position?
I would invest in some ferrites. E-bay is a good source. I would
clamp the AC line to the power supply, and the 12 vdc line coming out.
Also clamp everything connected to the radio/amp (coax, power,
control cables, etc.). The other school of thought is to only clamp
things until you find the one that is the problem.
If your antenna is 5 feet from your operating position, things may be
more problematic. As Ron suggests, antenna/feedline/balun may be the
culprit. Sometimes this stuff is hard to solve, glad you have help on
site.
73, good luck, Steve KW3A
