AM reception
Ionosphere
AM signal reception is usually better than FM
reception. This is because 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. Because of this, clear
AM broadcasts can be received at greater dis-
tances than FM broadcasts.

FM broadcasts are transmitted at high frequen-
cy and do not bend to follow the earth's surface.
Because of this, FM broadcasts generally be-
gin to fade at short distances from the station.
Also, FM signals are easily affected by build-
ings, 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.
