When the radio waves are reflected off objects or
structures, the reflected signal cancels the normal
signal, causing the antenna to pick up noise and
distortion. Cancellation effects are most prominent
in metropolitan areas, but also can become quite
severe in hilly terrain and depressed roadways.
To minimize these conditions, a stereo/mono blend
circuit has been incorporated into this system. This
feature automatically switches a weak stereo signal
to a clearer monaural signal, which improves the
quality of reception.
Several sources of static are normal conditions on
AM frequencies. These can be caused by power
lines, electric fences, traffic lights and
thunderstorms.
Another reception phenomenon is
Strong Signal
Capture and Overload
. This can occur when
listening to a weak station and when passing
another broadcast tower. The close station may
capture the more distant station, although the
displayed frequency does not change. While passing
the tower, the station may switch back and forth a
few times before returning to the original station.
When several broadcast towers are present
(common in metropolitan areas), several stations
may overload the receiver, resulting in considerable
station changing, mixing and distortion.
Automatic gain control circuitry for both AM and
FM bands has been incorporated into this system to
reduce strong signal capture and overload.
All About Radio Frequencies
The Federal Communications Commission (FCC)
and the Canadian Radio Telecommunications
Commission (CRTC) establish the frequencies that
AM and FM radio stations may use for their
broadcasts. The allowable frequencies are, AM: 530,
540...1600, 1610 kHz in 10 kHz steps; FM: 87.9,
88.1...107.7, 107.9 MHz in 0.2 MHz steps.
