[Elecraft] K3 s/n 1169 21MHz band distortion

[Joe Planisky]

Hi Jack,

Noise blanker settings can be remembered per-band, and very aggressive  
NB settings can cause distortion.  Is it possible you have set the NB  
levels for the 21 MHz band to very aggressive settings (e.g. dsp t3-7  
and/or IF wid7)?  Press and hold the NB button when on the 21 MHz band  
to see what settings you have and compare them to the settings on  
other bands.  Of course, turning the NB off for the 21 MHz band could  
tell you right away whether that's the problem or not.

Just a thought.
