Radio Frequencies
The radio can receive the complete
AM and FM bands.
Those bands cover these
frequencies:
AM band: 530 to 1,710 kHz
FM band: 87.7 to 107.9 MHz
Radio stations on the AM band are
assigned frequencies at least 10 kHz
apart (530, 540, 550). Stations on the
FM band are assigned frequencies at
least 0.2 MHz apart (87.9, 88.1, 88.3).
Stations must use these exact
frequencies. It is fairly common for
stations to round-off the frequency in
their advertising, so your radio could
display a frequency of 100.9 even
though the announcer may identify
the station as‘‘FM101. ’’ Radio Reception
How well the radio receives stations
is dependent on many factors, such
as the distance from the station's
transmitter, nearby large objects, and
atmospheric conditions.
A radio station's signal gets weaker
as you get farther away from its
transmitter. If you are listening to an
AM station, you will notice the sound
volume becoming weaker, and the
station drifting in and out. If you are
listening to an FM station, you will
see the stereo indicator flickering off
and on as the signal weakens.
Eventually, the stereo indicator will
go off and the sound will fade
completely as you get out of range of
the station's signal.
Driving very near the transmitter of a
station that is broadcasting on a
frequency close to the frequency of
the station you are listening to can
also affect your radio's reception. You
may temporarily hear both stations,
or hear only the station you are close
to.

Radio signals, especially on the FM
band, are deflected by large objects
such as buildings and hills. Your
radio then receives both the direct
signal from the station's transmitter,
and the deflected signal. This causes
the sound to distort or flutter. This is
a main cause of poor radio reception
in city driving.
Radio reception can be affected by
atmospheric conditions such as
thunderstorms, high humidity, and
even sunspots. You may be able to
receive a distant radio station one
day and not receive it the next day
because of a change in conditions.
Electrical interference from passing
vehicles and stationary sources can
cause temporary reception problems.
As required by the FCC:Changes or modifications not expresslyapproved by the party responsible for
compliance could void the user'sauthority to operate the equipment.
