RADIO FREQUENCY
INFORMATION
The Federal Communications
Commission (FCC) and the
Canadian Radio and
Telecommunications Commission
(CRTC) establish the frequencies
AM and FM stations may use for
their broadcasts. Allowable
frequencies are:
AM 530, 540Ð1600, 1610 kHz in
10 kHz steps
FM 87.9, 88.1Ð107.7, 107.9 Mhz
in .02 Mhz steps
Not all frequencies are used in a
given area.
Radio reception factors
Three factors primarily affect radio
reception:
²Distance/strength.The farther
an FM signal travels, the weaker
it is. The listenable range of the
average FM station is
approximately 40 km (24 miles).
This range can be affected by
signal modulation. Signal
modulation is a process radio
stations use to increase their
strength and/or volume relative
to other stations.
²Terrain.Hills, mountains, and
tall buildings between your
vehicle's antenna and the radio
station signal can cause FM
signal reception problems. Static
can be caused on AM stations
by power lines, electric fences,
traffic lights, and thunderstorms.
