Is your NB on? If it is, turn it off and see if it helps.

Wes,
All I know is that increasing the AGC threshold and setting the slope to
something other than the default will help. I don't know where the
non-linerity is happening, and I suspect something more is going on than
just non-linearity.

Well I didn't see what band it was on. If below 20M, the preamp should be
off and maybe attenuator on. Also the RF gain should be backed off.

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.

Unless I'm misunderstanding something here, the answer to your question
is pretty basic. There is a kink in the curve where the AGC kicks in.
Signals that traverse that kink see a nonlinearity.
I set the threshhold pretty high, and I set the slope as low as I can in
order to minimize the

This is VERY interesting.
I have never even thought much about AGC in my 8-year old K3, so I did that
just now.
I changed the THR to 12 and the SLP tp 003. Will watch for the difference.
I am really a CW operator here.
Thanks for the good wisdom!

Please explain to me where this non-linearity is generated. If 1 volt of RF

difference does it make if the 1 volt is generated by an AGC circuit or a manual
control? Either way, *all* signals are reduced 10 dB. What's
Boy, if I had thoroughly read the original post I would have seen you were
answering a question regarding a K3S! Humbling, and a reminder to slow down
and read the posts! I just wish I had a K4 coming ;-)

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?

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
You might turn AGC OFF or experiment with AGC settings.

Pete,
Go to my website www.w3fpr.com and look at the "Noisy K3" article. It
will help you adjust your AGC settings to help combat the mush.
