[Elecraft] K3: Noise reduction tutorial/primer available?

There was "straight talk" about NR from Lyle Johnson (who designed and 
implemented the algorithms) in his reflector posts of 8/25/09 and 
8/27/09 as well as the information in the Firmware Release Notes for 
version 3.30 (avaliable using the K3 Utility Help pulldown).
Page 25 of the K3 manual has a comprehensive description of the tools 
available  - Reducing Interference and Noise section.
The manual content is Wayne's work, so those who know most about those 
implementations have already spoken.
I am not certain how much more authoritative information you are seeking.
As far as explicit "Here is how you use it" - each individual case or 
instance of noise is different and will require different treatment.  
Each user will have to cycle through the settings available to see which 
works best - the result is a compromise, there is little that can move a 
signal out of the noise and provide a completely distortion-free and 
clear copy signal - copy will be improved, but just how much is improved 
and how much distortion is tolerable is a question each operator must 
answer.
