As far as the receiver itself, we have located a pretty good
CPU..................my boss wants to put in some fancy features, such as a
spectrum display, etc. I would also like to aim this receiver at the average
person, so I am thinking about bass and treble controls.

I may not be the average person... but some random thoughts away from
"fancy features":

1. A tuned front end? It really does make a difference.

2. Still using DDS for the LO? Make sure the encoder knob "feels" like a
good old variable capacitor (or variable inductor). I have been
universally disappointed by the shaft encoders used on current
synthesized radios.

3. The closer any spectrum display can be made to a good old panadaptor,
the better. They did that user interface right. Again, I'm disappointed
by the spectrum displays on current production hardware, but I may
be the last guy who still likes knobs over a bazillion mode buttons.
