I'm slowly rebuilding the detector and audio sections based upon the schematic mentioned above, and the radio is definately improving. I've got it down to under 20% distortion (you should have heard it before!). AGC is wonky. There's a good voltage range, but it doesn't seem to do a lot. The radio still overloads on strong signals. I have to keep my sig gen down to about 91mV or so. It's a challenge... but I LIKE a challenge.
