Many moons ago, before I got my ham license, I did some AM BCB DXing. I even went so far as to build a loop antenna. Even though it was very crudely built, it worked pretty well.
Here are a couple of links to plans for building similar loop antennas:

http://www.amfmdx.net/amdx/) mentioned above, and that does look like a great resource. I used to belong to the National Radio Club, and they have lots of good info on their site.
Good DX!
