It just seemed too funny not to post, but I hope the op doesn't take this as an insult as this is not my intention, just a friendly aside.
As for AM receivers, I would prefer to see what the op is already working on and offer suggestions for improvement rather than simply point to another schematic somewhere. He mentioned that he is working on one, so let's see it.
I'm sure that Blueroomelectronics' post was tongue-in-cheek, but seriously, that diagram would be a good starting point for explaining why and how AM receivers evolved over the years. Of course that might take many posts, but how educational it could be!
