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, 540±1600, 1610 kHz
FM 87.7, 87.9±107.7, 107.9 MHz
Not all frequencies are used in a given area.
Radio reception factors
Three factors can affect radio reception:
²Distance/strength. The further 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 ªsignal modulation.º Signal
modulation is a process radio stations use to increase their
strength/volume relative to other stations.
² Terrain. Hills, mountains and tall buildings between your vehicle's
antenna and the radio station signal can cause FM reception problems.
Static can be caused on AM stations by power lines, electric fences,
traffic lights and thunderstorms. Moving away from an interfering
structure (out of its ªshadowº) returns your reception to normal.
² Station overload. Weak signals are sometimes captured by stronger
signals when you pass a broadcast tower. A stronger signal may
temporarily overtake a weaker signal and play while the weak station
frequency is displayed.
The audio system automatically switches to single channel reception if it
will improve the reception of a station normally received in stereo.
