Erik,
Apparently something *did* change in your antenna system. It may not be
in the shack.
Look for something that arcs over at higher power or a loose connector
or a balun that has failed.

Today my KXPA100 stopped working properly. Whenever I transmit I start getting
feedback, a sort of electric stuttering effect. When the amp is bypassed this
does not occur. Also, if I transmit into a dummy load the problem does not
occur, indicating that somehow the antenna RF must be affecting the amp in some
way?
Nothing has changed in my shack since yesterday, and the problem occurs with
both my KX3 and KX2, so it's not the radio. Everything is fully grounded to a
copper bus bar on my desk. I performed the factory reset through the KXPA
Utility with no change.
Has anyone had this happen?
Thanks and 73,
