[Elecraft] (K2) distortion on CW receive

[Don Wilhelm]

Robert,

Do you have the KDSP2 installed?  If so, check the nr and nt settings in 
the DSP menu.
If you see a dot before either or both, turn them off and see if the 
distortion goes away.  Those functions, if used with aggressive settings 
will cause distortion.

The sidetone is fed separately and does not go through the DSP processor.

If that is not the problem, then you likely have mis-aligned IF 
filters.  I recall I have worked on your K2 before, and you should have 
a chart of the filter settings.  I can tell you how to restore the 
proper settings via off-list email.

73,
