NR distortion with 3.11

NZ0T
I don't use NR much and tonight was the first time I've tried it since downloading 3.11.    It seems to be very distorted even at the lowest setting and when I rotate the level knob I hear a clicking sound in the audio.  Anyone else had this occur?

Re: NR distortion with 3.11

I should add that I recently changed my AGC settings to those suggested by Don W3FPR to make the K3 sound more like a K2:

AGC PLS off
AGC SLP 002
AGC THR 008
AGC-F 140
AGC-S 010

Any other AGC settings that are better? Could these settings affect the NR in a bad way?  I work a lot of CW but also some SSB on 160 and that's where I noticed the NR sounding bad. .

Yes, the low slope (and perhaps the threshold) for my AGC settings
increases the apparent NR distortion.  So you have to make a decision
"better" AGC response or clearer audio when using NR.
Since I rarely use NR, I have made my choice.

It may be that someday soon we may 'have our cake and eat it too' when
Lyle works on the NR algorithms, but for now we have to make those choices.

I rarely use NR myself so most of the time I'll stick with Don's settings.  I downloaded K3_EZ and have several alternative AGC settings entered so now it's easy to change.  Thanks for the input Don.
