K3: recommendations wanted for NR setting

[Vic Abell]

I just completed K3 1162 and am interested in setting
its NR to an optimal value for combating summer QRN.
I am currently using "F 1--4" with some success, but
would like to hear about the settings others prefer.

Any other advice on other ways to reduce QRN and back
ground noise with K3 features would be welcome, too.

73,

Vic-W9RGB

I find for weak CW sigs that most of the settings over 1 are a bit
much...  I find that 1-1 and 3-1 are my two favs.

Pre Firmware 2.20 I uses AGC SLP 4 and AGC THR 8 to
make the K3 sound like the K2 AGC.  At least on CW.
And used NR F2-4.  That worked great at Field Day.

Since Firmware 2.20 I cannot find a setting that accomplishes
two things ....
Sounds like a K2 and the audio level for NR on & off is about
the same
And with NR on (most any setting) now the received CW  sounds
soft, or very slow attack time.  At higher speeds it is possible to
miss a leading dit in a character.  

But at this point AGC SLP and THR both equal to 2 works fine
(to my ears) with loud and weak signals, but when I turn on NR
the received signal goes very soft.   If I set NR = F1-1 through
F1-3 it isn't too bad.

Its kinda tough for me to give a good A/B comparison.  I had the rig for
a while then had to ship it back for a bit of work then when it came
back I upgraded...  I remember the NR working better before I got it
back....
