FM broadcasts are transmitted at high fre-
quency and do not bend to follow the earth's
surface. Because of this, FM broadcasts gen-
erally begin to fade at short distances from the
station. Also, FM signals are easily affected
by buildings, mountains, or other obstruc-
tions. These can result in certain listening
conditions which might lead you to believe a
problem exists with your radio. The following
conditions are normal and do not indicate
radio trouble:

AM broadcasts can be received at greater
distances than FM broadcasts. This is be-
cause AM radio waves are transmitted at low
frequency. These long, low frequency radio
waves can follow the curvature of the earth
rather than travelling straight out into the
atmosphere. In addition, they curve around
obstructions so that they can provide better
signal coverage.

How Car Audio Works
FM reception
AM and FM radio signals are broadcast from
transmitter towers located around your city.
They are intercepted by the radio antenna on
your car. This signal is then received by the
radio and sent to your car speakers.
When a strong radio signal has reached your
vehicle, the precise engineering of your audio
system ensures high quality reproduction.
However, in some cases the signal coming to
your vehicle is not strong and clear. This can
be due to factors such as the distance from
the radio station, closeness of other strong
radio stations or the presence of buildings,
bridges or other large obstructions in the area.
