[Elecraft] A very desirable capability

Peter,

Since "one size" does not fit all noise sources, I believe that what you 
suggest is not practical.
It may be that something could be done to provide the most useful noise 
reduction for "average noise", but the closest to that right now would 
be the default settings in the K3/K3S.

If you do not know what the default settings are, save your K3/K3S 
configuration, then do an EEINIT (Reset to Factory Defaults), then look 
at the NB and NR settings.  Finally load the saved configuration file 
and then set the NB and NR settings to the defaults that you recorded. 
Be aware that some of the settings are per band, so you will have to 
check them on each band.

That will give you a "one button" NB and NR as you might find in many 
other amateur transceivers.

I am glad that the K3/K3S offers adjustability for the NB and NR 
parameters.  It does take some study to learn how to use the parameters 
provided, but if you do that study, you will be rewarded with good noise 
reduction for most any type of noise.

73,
Don W3FPR
