[Elecraft] K3 Firmware 2.19

[hank k8dd]

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.
