[Elecraft] K2DSP: Adjusting Denoiser Levels

[Phil Wheeler]

Lyle,

After purusing the manual over dinner, I'm getting the impression that 
there is available one beta and one decay and that the nr1-nr4 changes 
are pre-programmed and not user available .. this from a statement on 
page 30: "The beta number seems to have a mild effect, especially with 
the noise reductoin level set to 1."

If so, it would seem I want to set decay to a lower level and let the 
nr1-4 add aggressiveness as needed.

Comment?
