Not really. Of course, you have to keep reminding yourself that only a
narrow slice of spectrum is really important in these applications. One of
the things that made me nervous was that hard clipping might throw garbage
from non-essential areas into that window. Since I run a 250 Hz filter on
the receiver, with an 800 Hz beat note, harmonic generation shouldn't be an
issue, though.

One of my little mysteries with WOLF is that I've had to be gentle with my
use of the "-b" blanking option. Other guys have posted great results with
it really cranked in. This may all tie into this issue of how hard the sound
card is being driven -- not sure.

In any case, I will be in a position to play with my own Jason signal and
Cool Edit over the weekend. I will certainly report any interesting results
(that seem to work on more than one file!).
