7400 competition entry: 80M direct conversion receiver

Jason added another entry to the Open 7400 Logic Competition:
80M direct conversion receiver

I had fun using the 74HCU04 to make a little TRF AM radio, but my original goal was to build a direct conversion receiver. I didn’t think I would have time before the deadline, but I managed to squeeze it in with less than an hour to spare!
