[Elecraft] K3 NR (was making K3 RX audio like K2)

[Arie Kleingeld PA3A]

When I was commenting on the NR, I did not have CW in mind particularly.
Definitely not NR in a narrow CW-filter situation. Lyle's explanation of
NR seems logical to me.

What I expect the NR to do is: enhancing the copyablility of SSB signals
that are in the local noise and barely understandable. Engaging the NR
at the present situation, I can hear something happening to the audio at
the different settings, but it does NOT make the signal sound better
copyable.
But if the NR is only for further de-noising already good signals...
then I set my expectations are too high. Please tell me I'm wrong here.

You may simply be expecting too much of NR.  It cannot overcome the
basic physics of noise bandwidth.  If you're already at a narrow CW
bandwidth, it will do very little except confuse you.  N.B. #6 below.
