[Elecraft] K3 Noise Reduction

[Bill]

Agreed! I have tried a bunch of settings and have some that really suit my
personal preference. Here's what I use on the lowest bands:

PRE off
ATT on

AGC DCY 	Soft
AGC HLD	0.50
AGC PLS	nor
AGC SLP	006
AGC THR	003
AGC--F	120
AGC--S	025
 

Very strong signals may give a little distortion, it could be their signal
is overdriven, but I use the RF control.  Noise from lighting static, and
neighbors very lousy electric fence is not bothersome.  

Hopefully through the sharing of different settings, those who might be a
bit challenged by the flexibility will be helped. 

I have saved these settings so I don't lose them when I diddle some more.

Is most of this discussion on NR in the K3 from users who would like to 
improve the SNR on louder signals for easier listening in noisy 
conditions?  

I get the impression we have people expecting different things from 
these controls.  The optimum AGC and NR design strategy to improve SNR 
for weak signals might be quite a different story than for stronger 
signals and noise, even if the SNR's are initially the same.  That might 
show up fairly dramatically on a rig with as large a dynamic range as 
the K3.

Since I mostly worry about readability on really weak signals I've had a 
bit of a hard time understanding what this was all about.  I just use 
settings similar to those suggested by W3FPR and K6LL and I've been very 
happy with the results ... which are much better than any Icom or 
Kenwood I ever owned.
