I am not suprised to see more AM's on Craig's List.
Just like the 8 track and cassette, of which I still have a lot of, AM radio is not on anyone's radar list under 60.
Too bad because in a rural area, where no large market signals can penetrate, you might have a chance at a successful business.
But come to think about it, even in the most rural of areas, you can get satellite if you have electricity, or internet if you have phone service. That is your connection to the world, not a daytime AM.
