Yes, indeed, I had a lot of fun getting Daves receiver to work properly and in the end, I managed to get pretty decent performance out of it. I've been thinking about a microcontroller based receiver too, but my strategy would still be to use the (built in) ADC and undersample the RF signal. It will take longer time to find the signal that way, but it should still work. A new crop of DSP chips have cropped up, like the TI 'F2812, and I'm seriously thinking about getting an eval kit for that and move my Loran-C over there.
