The problem is solved. I thought I have to share with others what worked
best or us. This solution came from Gary N7IR.
Try a few sheets of thin low carbon steel (in US called mild steel)
insulated from each other by sheets of printer paper. Put this sandwich in
between and parallel to the K3
Make sure there is a ground wire on the rotator controller.
That knocked the hum way down here. I had the same problem
with my TS-850's, and there were no audio input transformers
in that rig.
