Howard:
I don't have a dummy load here, but the problem does not exist at all when
no power is applied.
I just tried it quickly here with 50 watts, and again, no volume control
problem.
It seems to be a problem when I get up to 100 watts with the TS480.
SWR is 1 point 4 to 1 here on 40 meters where I am doing the testing.
Have to get to work now, but can do some more troubleshooting maybe tonight.

Tom, maybe, but maybe it's a problem with the volume control. Does the
problem go away if you use a dummy load?
