FM
Fading and drifting stations: Generally, the effective range of
FM is about 25 miles (40 km). Once outside this range, you may
notice fading and drifting, which increase with the distance
from the radio transmitter. They are often accompanied by
distortion.
Multi-path: FM signals are reflective, making it possible for
2 signals to reach the vehicle's antenna at the same time. If
this happens, the signals will cancel each other out, causing a
momentary flutter or loss of reception.
Static and fluttering: These occur when signals are blocked by
buildings, trees or other large objects. Increasing the bass level
may reduce static and fluttering.
Station swapping: If the FM signal being listened to is
interrupted or weakened, and there is another strong station
nearby on the FM band, the radio may tune in the second
station until the original signal can be picked up again.
AM
Fading: AM broadcasts are reflected by the upper atmosphere
— especially at night. These reflected signals can interfere with
those received directly from the radio station, causing the radio
station to sound alternately strong and weak.
Station interference: When a reflected signal and a signal
received directly from a radio station are very nearly the same
frequency, they can interfere with each other, making it difficult
to hear the broadcast.
Static: AM is easily affected by external sources of electrical
noise, such as high tension power lines, lightening or electrical
motors. This results in static.
