RF gain & AGC setting do more here on the OII than NR ever does...just
like the old days...somethings never change??
The NR just builds a filter around the signal to remove noise...so BW
adjustment is pretty much doing the same thing.
Whether it's a 1966 Collins 75S-3 or a OII...use that RF gain.
On the latest firmware...the NB has a big issue. If there is a fairly
strong signal near by (several KC's) then you can the signal on your
freq., king of like close in splatter.
Be nice to have that fixed.

Hi Guys --
I often use NR to advantage on SSB, and it can make a substantial
difference in reading SOME weak, noisy signals. HOWEVER... one's
satisfaction will depend entirely on his level of expectation. It
works well, as long as you do not ask too much of it. NR CAN help in
SOME cases, but is no panacea and cannot remove all noise, and it DOES
ALTER the signal. Noise is received right along with the desired
signal, and it affects the signal as it removes "some" of the noise.
Sometimes it helps, and sometimes not.
Thus NR becomes, in my view, AT BEST, just one more tool in the tool
box. Sometimes it is the right tool for the job, and other times, it
is not.
Just MY take.
------------------
Happy Trails.
