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.

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.
