Dave,

Yes, it applies to the K3/K3S, KX2 and KX3.
Try it, it works. I don't know if it will cure the particular CW Mush that you are hearing, but it is a good starting point.

Excuse my ignorance Don, does your K3 AGC, etc. article also apply to a
K3S? I assume it does, maybe receiver advice & tips I've  missed along the
way?
Thanks,
Tom NB5Q

What are your AGC settings?  I have a K3 with the new synths and I use
almost the least AGC possible ... THR = 12 and SLP = 000.

AGC creates non-linearity, the non-linearity is most pronounced at the
signal level where it kicks in, and non-linearity creates mixing.  Do
the math for the sum and difference frequencies when you have multiple
signals very close to each other within the receive passband.

My K3S is turning CW into mush.  Huge pile ups as K2D are really hard to
deal with.  Any suggestions other than get a K4 which I have on order?
