[Elecraft] K3 Noise Reduction

[David Gilbert]

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.

73,
