Radio Reception
Strong Signal Noise may occur when you are very close to a
Transmitter Tower. The broadcast signals are extremely
strong which causes noise and sound break-up at the radio
receiver.
When a vehicle reaches an area where there are two strong
stations broadcasting at similar frequencies, the original station
may lose it's reception and the second station will be
broadcasted. At this time, there will be some noise present
which we call Station Drift Noise.

Signals from a FM transmitter move in straight lines and become
weak in valleys, between tall buildings, in mountains, and around
other obstacles. When a vehicle passes through an area like this,
the reception conditions may change suddenly, resulting in Flutter
/ Skip Noise.
In remote areas, broadcast signals become weak due to
the distance of the transmitter. Reception in such areas
may experience Weak Signal Noise and sound break-up.

Radio Reception
Signals from an FM transmitter are similar to beams of light
because they do not bend around corners, but they do reflect.
Unlike AM signals, FM signals cannot travel beyond the horizon.
Therefore, FM stations cannot be received at great distances
compared to AM reception.
Atmospheric conditions can also affect FM reception.
High humidity will cause poor reception. However, cloudy days
may provide better reception than clear days.
IONOSPHERE

AM

60-120miles (100-200km)
FM

Since FM signals can be reflected by obstructions, it's possible to
receive both the direct signal and the reflected signal at the same
time. This causes a slight delay in reception and may be heard as
broken sound or distortion. This problem may also be encountered
when in close proximity to the transmitter.

signals can bend around buildings or mountains and bounce off

This is why AM signals can reach longer distances than FM signals.
An FM broadcast range is usually about 25-30 miles (40-50Km)
from the source. Because of extra coding needed to break the
sound into two stereo channels. FM has even less range than
