Audio Operation

Flutter/Skip noise

Signals from an FM transmitter move in

straight lines and become weak in valleys or

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.
