Terrain
*
[AS30800(R)05/96]
The terrain (hilly, mountainous, tall buildings) of the area over
which the signal travels may prevent the FM signal from being
noise-free.
*
[AS30810(R)05/96]
If there is a building or large structure between the antenna and
station, some of the signal ºbendsª around the building, but
certain spots receive almost no signal. Moving out of the
ºshadowª of the structure will allow the station to return to
normal.
*
[AS30820(R)05/96]
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.
*
[AS30830(R)05/96]
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.
*
[AS30840(R)05/96]
Several sources of static are normal conditions on AM
frequencies. These can be caused by power lines, electric fences,
traffic lights and thunderstorms.
*
[AS30850(R)05/96]
Another reception phenomenon isStrong 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.
