I don't recall the firmware revision my Orion had when I bought it but I do
recall turning on the NR and my jaw dropping. It was awesome. All the band
noise vanished and I none of the goofy dsp artifacts that most rigs have.
Then I "upgraded" to a new firmware and the NR ceased to work. Pushing the
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 NRs
are working and some are not or not much.
