First, turn off "Flatten," which will get rid of the yellow and red
peaks at either end.
Second, set Start to 250 or 300 Hz and Bins/Pixels to 4 or 5, so that
the display shows only the bandwidth of your IF (in this plot, audio
from 350 Hz to 3.55 kHz). Audio frequencies outside these limits don't
get through your IF and roofing filters, so don't waste DSP on them.
These comments apply specifically to WSJT-X, but the same concepts are
at play in FLDIGI (which I don't use, so can't help you with).
