Radio Frequency Information; Radio Reception Factors - Ford 1999 F-350 Owner's Manual

• Do not expose tapes to direct sunlight, high humidity, extreme heat or
extreme cold. Allow tapes that may have been exposed to extreme
temperatures to reach a moderate temperature before playing.
• Tighten very loose tapes by inserting a finger or pencil into the hole
and turning the hub.
• Remove loose labels before inserting tapes.
• Do not leave tapes in the cassette player for a long time when not
being played.

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 87.9
b
, 88.1–107.7, 107.9 MHz
Not all frequencies are used in a given area.
a
Some radios may tune up to 1710 kHz.
b
Some radios may tune down to 87.7 MHz.

Radio reception factors

Three factors can affect radio reception:
• Distance/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 "signal modulation." Signal
modulation is a process radio stations use to increase their
strength/volume relative to other stations.
• 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 "shadow") returns your reception to normal.
• 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.
