AM is the only way I can get stations from out-of-town without an internet connection. There's one that's about 70 miles away that comes in during the day. Then at night I can't listen to it as another station interferes, but I get a lot of other AM stations at night.
FM is limited to basically line-of-sight. As soon as I head over the first hill 8 or 10 miles away from town the signal disappears, which is also where cellphone service ends too.
