[Elecraft] K3: Noise Reduction - FWIW

[KD8NNU]

HI Jim,

Would be so kind as to share your settings that give you a sweet spot and 
what is the nature of the noise that drove you to that setting.

Thanks in advance.

I have read with interest the e-mails regarding the K3 noise reduction 
feature.  I will post my observations herewith.  It took a bit of work to 
find the "sweet spot" setting for my noise environment. Once found, it has 
proven to be quite satisfactory. Having worked with a number of SDR type of 
radios (Flex, Yaesu, and now K3 and for that matter K2) I can say that, in 
my opinion, the K3 is as good as it gets. I sense a number of users may not 
be entirely familiar with noise reduction as it pertains to a software 
defined radio. In some cases, it seems one is trying to use noise reduction 
where one should be using noise blanking, a common mistake in attempting to 
reduce impulse noise from power lines. Another common mistake would be to 
solicit the settings from another user in a different noise environment.

One resource I found to be of benefit to me in helping me to understand the 
"processes" of DSP  is "The Engineer's Guide to Digital Signal Processing" 
by Steven W. Smith.  It is a free download from http://www.dspguide.com.
