[Elecraft] K3S audio quality issue

[Don Wilhelm]

Mike,

That problem sounds a bit like the Calibration of the Reference 
Oscillator is off a bit.  See tha manual and use the Zero-Beating method 
as instructed.
There is a chance it will help, but no harm if it does not.

If you did not get the paper manual, download it from Elecraft.

Sometimes it's better (less artifacts) when it is a little bit lower, but it sounds unnatural. AM seems to be fine. Of course, the first thing I did, I made sure that the EQ was flat and all DSP I know about was off. No NB, NR or AFX. Currently it happens only on 20M, 40M seems fine, haven't checked the others yet.
