[Elecraft] K3: Noise Reduction - FWIW

[W4ATK]

	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.
