In my Kachina the second IF is under 100 khtz , this is where the dsp is.
the dsp does the detection.

The Icom 746pro and 756proII both use DSP in the IF stage. I use the
756pro and it's a wonderful rig.


So is the 746Pro. I have never had a better Rx. The noise reduction
and
filtering capability can not be beat by any other rig even close to this
price range.
