I don't know if expanding the explanation about the effects of things in the
docs would help. Like what NOT to do.Seems most don't read them anyways...but
maybe we should do it anyways for those that do.
The more education the better IMHO....
So instead of
Use the receiver gain controls and/or the computer’s audio mixer controls to
set the background noise level (scale at lower left of main window) to around
30 dB when no signals are present. It is usually best to turn AGC off or reduce
the RF gain control to minimize AGC action.
This instead (comments welcome).
Set your audio card to 0dB. In Windows you can look at the Levels on the
Recording device and right-click to get dB scale. As close to 0dB as you can
get is what you want. There should be no gain or attenuation as this is a
digital control and any gain/attenuation does pretty much nothing. (Mac and
Linux directions too should be here).One your audio card is set to 0dB use the
receiver gain controls and/or external analog audio device control (e.g.
Signalink) to get 30dB on the meter when no signals are present. It is
usually best to turn AGC off or reduce the RF gain control to minimize AGC
action. Only analog controls should be used to adjust the incoming signal
level.
Note: Version 1.8.0 disconnected the slider from the meter. The slider never
did control recording level, it only controlled the waterfall level. The
slider now only controls the waterfall level on both the Fast graph and Wide
graph, though if Flatten is checked on the Widegraph than the slider control is
not effective.

So...preferring usability over confusion was the result and it was decided to
keep it on the main window.
It will be a teaching process and I'm sure we'll get lots of "slider doesn't
work anymore" -- but the education process is well worth it. If we took it off
we'd get the same questions except "what happend to the slider" -- still
requiring the same education.
The tooltip on the slider tells you exactly what it does. Maybe we should
stick a "THIS DOESN'T CONTROL THE METER ANYMORE" in there...but they still
wouldn't read the tooltip in all likelihood.
Or maybe a splash screen that tells the major differences?
HI Mike, my experience and that shown in some posts here is that users will
still misunderstand and adjust the Windows audio sliders to get the level meter
around 30 - 40dB. It is a good thing that the level is not too critical as so
many believe that digital gain controls do something cleverer than simply
multiplying or dividing the sample values by some factor. Clipped cannot be
unclipped and in the noise cannot be extracted from the noise by doing that.
