When holding in the NR button to adjust noise reduction, I get
F1-1,2,3,4 then F2-1,2,3,4 etc for F3 and F4. Going further this is
repeated for NRmF5, F6, F7 and F8.
Can someone direct me to where in the K3 manual it explains what these
settings mean and/or when to use NR or NRm?
Thanks.
You'll find it on page 25.

I operate mainly CW and while the NB is very effective for me on CW,
I've never seen much advantage to the NR at narrow CW bandwidths. I had
occasion to be on SSB this week attempting to work several SOTA summit
activations, and tried the NR. At the wider SSB BW, it made a great
difference.
Hi,
Have you tried the NB (*not* NR)? I find it very effective against power
line noise. I use the setting t2-6, IF off. For a long time I was using a
combination of DSP and IF setting, but found that the IF contribution was
little or non-existing, so I switched to DSP NB only.

Fred,
Perhaps an explanation of how NR works will help you understand what you
are hearing a bit better. The NR algorithm looks for some sequence that
it can define as a signal, and then builds a filter around it. The type
of filter is determined by the parameters you have set.
That is why

both ears.

I also note the hollow sound to SSB when using the K3 NR. If I use it
at all, it's at the lowest setting, 1-1. I had the same listening
experience with the K2 DSP NR unit. It worked well on CW - sometimes
miraculous - but for my ears, useless on SSB. The K3 NB works on all
modes, every time. I
Hi Fred,
From where I sit, if the NR display has a little m between NR and F,
those are methods best on voice (F5-1 through F8-4), while without the
little m (F1-1 through F4-4) are methods better with CW. That is not an
absolute rule of course and many people have preferences which don't abide
Hello,
When I hold NR button to adjust noise reduction, I get levels F1, 1 to 4, then
F2 1 to 4, up to F4.
Clearly, 1 is least, 4 is most, but what do the F's represent? (Can't find any
reference to this on page 24 of the manual.)
I wondered if F refers to filter, if so then why not 5?
Thanks
