I would first suspect RF feedback.
What happens if you use only the K3? Connect the K3 to a dummy load and
listen with your KX3. That will tell you more than having someone do a
recording off the air.
If the K3 is clean, then you can conclude it is either the amplifier or
RF Feedback.
If the bare K3 still has a problem into a dummy load, look at the TX EQ
settings.

I reduce the power to one half, and no change. Also the problem varies from
band to band.

Similar harshness with power limited to 500W. I suspected the amp's
nonlinearity. But KX3 with the same amp (400W out) sounds smooth.
