Hello Russell,

Yes, I did look at the TDA7000. Long story short, I think it would be
almost too easy, I am hoping to gain some basic RF design experience
which I don't think a dedicated receiver IC would provide. Also, the
TDA7000 is FM only (not a big problem) and seems to be getting a big
long in the tooth (is not stocked by Mouser or Digikey). If I were to
go that route, I think I would use something that I could readily buy
since I'm not a big fan of buying chips from Ebay (or other less
reputable electronics distributors).

Thanks,
-Jason White
