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.
