It is possible that there is a problem in the RF gain pot. It IS a potentiometer. It has a standard voltage across it, and the variable voltage in the pot's "wipe" is sent to an analog to digital converter, which converts the pot setting to "numerical advice" which can be more easily sent to the CPU over one of the various digitally multiplexed communication busses.
It could be a non-linearity in the potentiometer, where on a normal K3, the "sweet" spot would be a point in the gain setting where the absolute unchanging difference between signal and noise is interpreted most favorably by the ear/brain which has its own way of hearing. That trick has been around for a long time. 73, Guy.
