You mention that the TX IMD gets worse when run at 120 watts.
The K3 is specified at 100 watts. If you run at 120 watts, it is

To me the current granularity with SHIFT/WIDTH (50 Hz) is fine. With LO/HI
it is 100Hz, which is too high for LO. Also, LO often changes from 0.00 to

bug.

Have you checked for any damage to the circuit board traces? If
enough power was applied to fry those resistors despite D1 D2
being in the circuit, maybe some of the traces were damaged as well.
I would think it would be visually obvious, but maybe not.
