Any AMRAD types besides me want to look in on an improved
experimenter's receiver board?

You could contact Microtune.  Note that boards were about $500, and
required 4 external power supplies.  The module itself works fine,
but it would be nice to have a different eval board that:

  (1) different parallel port pin out so that no SUID program is
      required to twiddle the bits.

  (2) on board generation of -5V and RF-AGC and IF-AGC control levels,
      either from power leached off of parallel port, or from single
      external +5 supply.

  (3) Dual trim dacs hung off of the I2C bus, to control the RF and
      IF AGC voltages.

If you're interested in laying out a new board, I can help with the
