Someone asked me awhile back if the Digital Signal Processing
DSP in the Icom 7000 was in the audio circuit or the IF.  I
happened to be reading the manual last night and stumbled across
this information.  The DSP is indeed sampling the signal from the
IF.

     Speaking of which, last night I was working a guy in Ohio on
30 meters.  I check 30 meters often and especially later at night. 
I do so by checking to see if I can hear WWVH and the female audio
in Hawaii on 10 Megs.  Her signal was really loud last night about
9 PM local so I went up the band and heard some CW signals.  I
punched up a few CQ calls and got a guy from Ohio with whom I rag
chewed with for about 30 minutes.  Although he was pretty loud,
and the line noise was low, there was a lot of weird background
hash and hiss coming through so just for fun, I snapped on the
DSP.  Fifty percent of the noise disappeared and he came through
loud and clear.  I didn't have to turn on any crystal filters at
all to copy him 100 percent.  So, I am very much impressed with
the DSP, at least for CW operation, with this radio compared to
the Icom R75 receiver version of the DSP feature.
