Corrected entry: Throughout most of the film John Cusack listens to a radio program on 745 KHz AM [medium wave]. In the United States, this frequency would almost certainly be impossible to hear in a car, due to U.S. frequency spacing of 10 KHz per station.

Correction: The radio station with 745kHz AM frequency is fictional and need not be scaled with the real word. To comply with the 10kHz spacing, the other fictional stations [even if not mentioned in the movie] could be 755, 765, 775kHz and so on. In the same way the telephone number prefix 555 is unused; hence, almost always used for fiction.
