AM radio reception
AM signals, because of their low frequency, can bend around objects and skip along the ground.
In addition, the signals can be bounced off the ionosphere and bent back to earth. Because of these characteristics, AM signals are also subject to interference as they travel from transmitter to receiver.
Fading: Occurs while the vehicle is passing through freeway underpasses or in areas with many tall buildings. It can also occur for several seconds during ionospheric turbulence even in areas where no obstacles exist.
Static: Caused by thunderstorms, electrical power lines, electric signs and even traffic lights.
