All,
If you can figure out how to keep the relatively thin "Z" panel from
expanding and contracting as it is heated and cooled, you will have a
solution to the problem.
It reminds me of my childhood days living with a coal furnace. The
furnace had an inner cast iron furnace surrounded by a sheet metal shell
as the air plenum.
It was comforting on a cold winter's morning to hear that sheet metal
expanding because that was the 1st indication that warm air was coming.
It was my job to shake down the ashes, put coal in and stoke up the fire
in the mornings.

I do run 400 watts or so on digital modes. Issues are not really noted on SSB

I've set the Fan Ctr to 2 and 3 and still noted the issue
Was recently showing my K Line to some hams friends. They commented rather
negatively on the point.

I've not experienced the problem with kit-built S/N 0651. But then, I have
never used it on high duty cycle data modes.

I rarely hear anything from my KPA500-F. Serious question, I wonder if
those with the kit experience more noise than those with factory
assembled units?
