FM broadcasts are transmitted at high frequency
and do not bend to follow the earth’s surface.
Because of this, FM broadcasts generally begin
to fade at short distances from the station. Also,
FM signals are easily affected by buildings,
mountains, or other obstructions. 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:

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. How-
ever, 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.

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