Gee, I don't know .... To only say "the audio went up, or down, when I
loaded X.xx" doesn't tell me anything!
What was the AGC SLP? AGC THR? NR settings?
With out that information, yes - it can go up or it can go down when you
turn NR on!
I just loaded 2.20.
The audio went way up when I turned on NR - I was using the XG2, 50 uV on
80M.
SLP= 4, THR= 8 NR= F2-2 and I had really liked the way the radio sounded
with the 2.1x's, but with FW 2.20, NR would hurt it was so loud. Almost
triple while monitoring AFv.
Changing SLP = 14, THR = 5 got the audio real close ..... but the radio
sounds like crap. OK ..... that's a personal observation of what it sounds
like to me on 80 CW!
I'm not sure I understand everything I have read about SLP and THR! Nor do
I want to. I want a radio that sounds close to or better than the K2!
So there's what I think.

Also with my K3 there is a significant reduction in the audio level
when NR is on. I don't see how the AGC would affect the NR. It's just a
function of the filtering that reduces the volume when the NR is
activated. Or is there something I am missing.

Hi Roy,
Try AGC THR = 5 and AGC SLP = 8....and or experiment with varying
those two parameters as you monitor a signal.
My AF gain is at the 9 o'clock position, AFX on, BIN option.
I use a couple of small RCA/Radio Shack speakers.
To my ears, the difference between NR on/off is really close to the
same audio level.
But as Lyle says, experiment, it is quite revealing!!
Best of luck!
