Phil what rig were you using? I know that dsp is really great.

Subject: Another DSP Experience

So the other night on 40 meters, the thunder storms over the planes were =
killing the band.  I often listen to a couple of high speed guys for =
practice because when they are in contact, they normally run 45 to 60 =
words per minute.  They often hang out on 7032 if you are interested = using
W4NPX and W6WXZ for call signs.  This particular evening, both the = Florida
station and the Californian were running strong 10 over S9 = signals but so
was the peaks from the static crashes.  At high speed CW, = fade, QSB, or
sudden static, QRN, can take out two or three words so the = louder, the
better.  I was copying them both fine but the static crashes = were wiping
out several letters and words at a time.  Just for fun, I = snapped on the
DSP.  The static crashes were all but gone and I no = longer was missing
anything as before.  Years ago, when running a 2 = element 40 meter beam at
70 feet, summers, beaming east, were killers.  = I soon learned, if I didn't
want to listen to all those static crashes, = I could beam to the west,
reducing the static crashing by about 20 DB, = and work western stations
just fine.  The DSP works, for CW signals at = any rate, way better that I
thought it would.

Phil.
