[Elecraft] KX3 Receive Noise

[Jim - W6VAR]

I haven't used my KX3 in a while and updated the firmware. In CW mode, I
notice there is substantial receiver noise at low volume with headphones.
The noise appears to be more active when a received CW signal is present.
Also, activating the attenuator also increases the noise and distortion.

The received CW tone also seems to get tinny and distorted at minimum
volume. ie - at zero volume, it is quiet, turn up just enough to start DSP
hiss (AF-1). Turning up the volume tends to drown out the noise, but it is
WAY to loud in my earbuds...I only need the lowest AF setting to hear just
fine.

Thoughts?
