I do have the same feeling; in these days (since 1.372 DSP gain control
introduced) the NR improves signal to noise ratio. Check out ages 15/16
and 46 of the manual.
I think under quiet band conditions no NR is needed but a "real (LF) NR"
system as in the Omni 6+ and apparently in early Orion firmware versions
wud be nice to have too. Maybe release 2.0 gives us the option ??
Guess "real" NR is more often required than SN/R improvement?? (160m?)
Am I missing something ? and just FWIW (consider myself not being a real
technician nor an analyst)

I don't recall the firmware revision my Orion had when I bought it but I
recall turning on the NR and my jaw dropping. It was awesome. All the
noise vanished and I none of the goofy dsp artifacts that most rigs
Then I "upgraded" to a new firmware and the NR ceased to work. Pushing
button had a tiny effect but it was almost useless. I tried many master
resets to no avial. I think we see different opinions here because some
are working and some are not or not much.
