We're going to make NR per-mode in the next firmware release, too.
This should eliminate the need to hunt for the ideal setting each time
you change modes.

Over the past two months I've been enjoying weak signal low band DXing on good
antennas with my K3 using roofing filters for CW (500Hz) and SSB (2.1 KHz) . My
K3 has the latest DSP board and the firmware is up to date with the
thirty-two(?) NR choices. What I'm finding is that the NR Firmware
The DSP is behind the roofing filters. I set my 400 Hz filter to cut
in at 450 Hz width. If I set width to 500, the K3 uses the 1.8 kHz
roofing filter. The information diversity of the noise vs CW signal
as a ratio is much larger there and the algorithm seems to take
advantage of that. To my
Hi John,
Exactly so. Lyle Johnson explained how NR works in the K3 a while ago
and he said exactly what you've observed: NR works best with wider
bandwidths. You can see his explanation at

I've been pleasantly surprised at how well NR works even with
very narrow CW bandwidths. I routinely use a 250 Hz roofing filter
followed by 250, 200, or 150 Hz DSP filters for Top Band. The NR
set around F1-2 or F1-3 quite often makes a difference for me.
It wasn't always this way.
Thanks to
