[ICOM] proll review from e-ham [he dont know how to use it]

[John Geiger]

How is the IF DSP in the 756PROII?  I have had a
TS2000 in the past, and the IF DSP on those units
would remove background noise, but would also
introduce some other unusual sounds into the mix.  On
SSB, the DSP did make a somewhat hollow sound, and you
really had to adjust the filters just right to get it
to sound good. On CW, the DSP added something that
almost sounded like water bubbling in the background. 
It was effect at taking out noise, but also added
these other noises.  I don't notice near as much of an
effect on my 756 non pro unless you crank the DSP up
too high, where you get some crackling.
