Thank you Tim for the suggestions. My problem is
not related to having the NR engaged.
Actually, I tracked this problem down to my powered
speakers which I normally use to listen to the SDR-1000.
The speakers have a surround sound control. If this
control is on, there is an unusual effect on the audio which causes the BIN
mode
to be louder than the non-BIN mode. There must be
some phase differences created by the surround effect that causes
cancellation
and a relative decrease in volume when this control
is on.
This has nothing to do with the sound card, which
obviously also has to have its sound effects turned off.
After 29 months of using my SDR-1000, I still have
things to learn about the basic set-up of the SDR.
For all the newbies out there, hang in there, don't
despair, it only keeps getting better!

Craig,
Do you have Noise
Reduction engaged at the time you switch to BIN mode? If so, NR is not
available in BIN mode so when you engage BIN with NR enabled, there will be a
volume increase.
Otherwise, there is
no difference in volume when I switch in and out of BIN
mode.

[Flexradio] BIN mode
Just a basic question regarding
the BIN mode:
I have noticed for a long time
that the volume of sound increases significantly when I engage the BIN mode,
compared to non BIN mode.
Is this because of I and Q
imbalances that are reducing volume output in the "regular" mode, or is it
because of differences in normalization of the sound output in the two
different modes?
I would prefer that the volume of
sound be about the same in both modes. I find myself using the BIN mode with
weak signals because everything is louder. However, the noise reduction does
not work in the BIN mode.
What's going on? Is this just my
hardware setup or is this happening for
everyone?
