DSP in IF Stage?
 

There's a number of commercial amateur transceivers that have
DSP in the audio stages but do any have DSP in the IF before the
detector/AGC?

It can certainly can be done, it's pretty common now for radios to use DSP
at up to even a couple of hundred MHz. Whether there are ham txrs with this
I'm unsure of.

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.

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

The TS-2000 has a 12KHz IF feeding the DSP. All those old hardware tasks
done in software now.
