[Elecraft] K3: Noise Reduction - FWIW

[Fred Smith]

Yaesu set a new standard with the 5000 series like nothing prior that they
ever had. As for the Flex IMHO that needs to go to a computer forum as that
is what it is and yes I know all the hype it's the mouse and no KNOBS!

Subject: [Elecraft] K3: Noise Reduction - FWIW

	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.
