I find the K3's NB function fantastic. NR works very well, but it takes a
while to tweak it in. Bill's idea below sounds like a great idea!

Certainly not - any firmware changes to the K3S are applicable to the K3
as well. But the K3 is now 10 years old, and there is now not much new
engineering effort going on to make improvements. If problems develop,
they will certainly be addresses - perhaps even with top priority

Yes, perhaps the RIT knob could be employed to step the NR selection
between F1, F2, F3, etc. The RIT control is not used for anything while
the NR display is engaged.

The NR change I would like is "just" a UI change. If I could
temporarily set up two knobs to change the two parameters it
would be a lot easier to play with the settings and find the
best combo. Having one knob means having to remember how well a
setting several twists away works; much harder.

Given the way processors improve in speed with time (Moore's
law), the idea of a new DSP could mean just that. The big issues
I see are RFI, power consumption, and heat.
If we go in the direction of adding AI to the mix, then we will
need more storage as well as more processor. (Your phone rel

Assuming that there is enough processing power available, and the
architecture physically allows the mixing, manually steering either the
peak or the null should be achievable. There is a slight subtlety in
that one is trying to achieve a constant time delay at RF, not a
constant phase change,

Don,
No, it isn't the same at all and I don't understand why you think it
is. Your brain may be able to discern differences in phase and try to
focus in on one signal versus others, but it isn't going to do any of
these things:
1. Actually amplify a desired signal (probably 2 to 3 db) at

When they are driven from the same synthesizer, they are indeed "phase

I’m not an engineer but from the discussions here in the past, in diversity
mode, the VFOs are not “phase locked” but actually driven by the same
synthesizer, so they both get the very same frequency info. Thus output the
same frequency.

Dave,
Using Diversity Receive, the human brain does that automatically (but
not with the numbers). You can sort out both signals and automatically
pick the best one or a blend of the two. This is an unconscious process.
The name of the game is communications, not looking at numbers

I know Wayne requested direct replies to his query and I've already done
that, but I have a serious suggestion and I'm curious if others here
would be interested. Here it is:
