If the problem came on suddenly, that suggests a connector or wiring problem. Check
to be sure everything is tight and there are no breaks in the shield, etc.

The two antennas are a zs6bkw and a OCF dipole. Both are up about 32 feet and
the ends are 12 foot off the ground. The coax is LMR400 and is new. The
antennas are located on the opposite side of the house from the shack. The
amp is powered by a 240 volt plug and the power supply is 110 volt.
This happens in all modes, CW, Voice, Psk31. It happens on all bands. It
only happens when the power is increased to 300 watts or higher.
My station ran great for several months 6 to 12 months. Then all of a sudden
this problem showed up.
I will start filtering everything tomorrow to see if that helps.
Thanks for the replies I will try your suggestions
