Similar harshness with power limited to 500W. I suspected the amp's nonlinearity. But KX3 with the same amp (400W out) sounds smooth.
I would suspect that the amp is being overdriven. How much power out from the K3? Are you using ALC between the K3 and the amp to set the TX power? That's a known cause of nasty distortion. The right way to do it is to reduce power from the K3 until you get the desired output from the amp.
