John, change the amount of spectrum you display. Adjust the two
sliders just below the waterfall/panafall display so you are
displaying maybe +/- 10 KHz. I routinely only view my freq +/- 10 KHz
and have enough resolution to identify signals by their appearance
alone. I routinely click on RTTY sigs and am tuned to within 30-40 Hz
just by clicking, because I can distinctly see both the mark and
space tones (170 Hz apart) and the valley between then . I can also
see the broadening of the lines caused by the shift in PSK, etc. I
think that is what you want.

What controls the maximum resolution on the abscissa of the
waterfall view? I understand about FFTs, sampling rates, etc. but
don't understand why the waterfall in pSDR is so muddy compared to,
say, FLDIGI or DigiPan, seeing that they are processing the same
audio stream with their FFTs. I have played at length with the
"Display" controls in Setup without being able to effect any
improvement in the pSDR display.
