Tim,
My more general response was not directed at you (as it indicated), but
at the reflector in general. Because these sorts of questions get
archived, many times similar questions come up. I hope you understand
that we ENCOURAGE these types of questions and interaction on the
reflector.
It sounds like you have a good handle on where to go for resources when
you run into a problem, but many people searching the archives do not.
This was the reason for my mentioning the manual in my previous
response. (throw Teamspeak in there somewhere too) ;)
I probably did not adequately respond to your original question given my
more general response (again, more for the sake of the archive than
directed at you).
I will say that we have fixed an AF bug that was causing lower audio
just today. This will be in the next release (v1.4.5 Preview 6).
However, I'm not sure that this is typical operation for the NR (much
lower volume). It sounds to me like the values might be too aggressive
for your particular situation. N4HY aka the expert would likely be
the best person to comment here.

Eric,
I did use the manual as a starting point for inquiring about my
question. I understand the function of the controls as described and
did play with the settings.
I think you misinterpreted my question. I am not complaining about
the
quality of the ANF or the NR to do their respective functions. Nor
did
I inquire about how to manipulate the ANF and NR controls.
I have just noticed that when the NR is engaged, I have to really turn
up the AF to get back to a comfortable listening volume. If I forget
to
turn it down before I disengage the NR, it hurts my ears when wearing
headphones. Is this normal? I didn't know so I asked the question.
And BTW, I don't feel that asking these types of questions warranted a
RTFM reply. The radio is new to me and it is evident from reading the
forums that things can change drastically from release to release.
Pardon me for being curious.
-Tim

Tim (really directed more generally),
The ANF/NR settings are highly subject to band conditions. What works
for us here in the lab doesn't always work for N4HY in NJ. We have
selected values that seem to work fairly well across the bands _for
us_.
When the ANF is working properly, I have seen it notch as many as 4
carriers inside the passband with excellent attenuation while coping
an
SSB signal.
The NR seems to be pretty hard to describe other than the fact that if
you get the settings right, you will be able to copy stations down
near
the noise that were just barely audible before. N4HY might be able to
describe these functions a bit better.
The Operating Manual does an excellent job of describing the controls
that manipulate the NR/ANF. Please use this as a starting point for
these types of questions.

Subject: [Flexradio] Just wondering about the NR
Pardon, the basic newbie questions, but I just want to make sure
what
I
am experiencing is the norm.
I have noticed that if I engage the DSP, the audio volume decreases
by
about 40% (subjectively). I would expect some decrease in AF
intensity,
but is a 40% decrease the norm?
BTW, I am not experiencing any modification of the audio
characteristics
using the NR other than some of the high frequency components are
attenuated. None of the being in a fish bowl and listening at the
end
of a pipe characteristics reported by others.
Setup: AMD Athlon 64 Dual Core 4400+, 1 GB RAM, Delta 44 (64-bit
drivers), SDR-1000 (full stack w/o tuner, all current mods), W2IJHY
EQplus Heil PR20
