We might want to try and list what receivers there are that stay on
without their main softwares and have a live I/Q signal running so we
know which ones that SDRadio and Winrad work with directly.

  True you can only tune directly from the softwares display, but in HF
sideband there can be quite a few signals there to work and you might
stay there listening all night in an area.  Winrad digs them up out of
the noise real good.  It is really sort of spooky to pull up them
signals thats in the noise.  I can hear signals I can not see that well
on the displays.  The waterfall display opened up on contrast will
reveal them a little.

  SDRadio has some unbelievable sound reproduction on broadcast
stations.  The bass is solidly reproduced and not muddy or bland and
the mids and highs are detailed in accuracy.  You can use "Audacity"
Sound Studio ( @ Sourceforge ) and record from SDRadio off of the "wave
out" as Audacity's input source.  SDRadio seems to have +6 to +9 dB
more signal to noise ratio than my receivers main software and Winrad
is the same way with sideband.  

  It might be my imagination but it seems they both have some spurious
tone rejection or random running auto notch filter action?  The spurs
appear to be minimized somehow.  Their still there though.

  Note: Audacity was originally custom compiled for radio station
broadcast studios and you might be surprised at what it can do.  It
even adds in custom sound effects.  It processes the audio when you are
done composing it.  It also saves it all in a special text file that is
only a few kilobytes rather than a multi mega byte wave file but you
can convert it to a wave file.  It saves disk space.
