Flutter/Skip noise

Signals from an FM transmitter move in 
straight lines and become weak in valleys 
between tall buildings, mountains, and other 
obstacles. When a vehicle passes through 
such an area, the reception conditions may 
change suddenly, resulting in annoying 
noise.

Weak signal noise

In suburban areas, broadcast signals 
become weak because of distance from the 
transmitter. Reception in such fringe areas is 
characterized by sound breakup.

Strong signal noise

This occurs very close to a transmitter tower. 
The broadcast signals are extremely strong, 
so the result is noise and sound breakup at 
the radio receiver.

Station drift noise

When a vehicle reaches the area of two 
strong stations broadcasting at similar fre-
quencies, the original station may be tempo-
rarily lost and the second station picked up. 
At this time there will be some noise from 
this disturbance.
