Most legacy receivers are designed for 10 meters. Within this point,
this generally says the receiver gain on lower frequencies is somewhat
excessive. Plus typical of most environments, the band noise increases
as frequency decreases. Additionally, the ear has the ability to easily
discern
Bob K4TAX,
Why 10 to 15 dB above - is your idea to have some margin for band noise
floor changes? It seems you'd maximize dynamic range by making the two
equal.
Tnx es 73,

Once again, a beautiful post by Bob. His description suggests a feature that
could be put into any new transceiver.
Imagine a graphical depiction of Bob's scenario below on the color screen of
the radio which would help you optimize the placement of the dynamic range of
the radio with respect
That is a pretty good description of how the KX3 NR works right now, except it
doesn’t have a graphic UI.
From the release notes for 1.47:
The RX NR menu entry can be used to adjust all three NR parameters (B=beta,
D=decay, M=wet/dry mix). The M parameter now has a range of 0-10, matching the
One point I've observed is the fact the noise on a given band may not be
the same from day to day, or week to week. Thus I find it necessary to
tweak the values of NR and NB for best performance. Same issues with
band to band, i.e. what I need on 80M is no where close to what I need
on 6M in
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
I agree 100%
