If the sound skips:
Badly scratched discs or extremely rough
roads will cause the sound to skip. Skipping
will not damage the disc player or scratch the
discs.
Common Radio Reception
Conditions
Several conditions prevent FM reception from
being completely clear and noise-free, such as the
following:
Distance/Strength
The strength of the FM signal is directly related
to the distance the signal must travel. The
listenable range of an average FM signal is
approximately 24 miles (40 km). Beyond this
distance, the radio is operating in a "fringe" area
and the signal becomes weaker. Also, "Signal
Modulation" is used by some stations to increase
their "loudness" relative to other stations. The
difference in loudness can be a result of signal
modulation as well as signal strength.

Terrain
The terrain (hilly, mountainous, tall buildings) of
the area over which the signal travels may
prevent the FM signal from being noise-free.
Repeated pops and hisses which are heard during
an otherwise clear broadcast can occur near the
station because of the "line of sight"
characteristic of FM radio waves.
If there is a building or large structure between
the antenna and station, some of the signal
"bends" around the building, but certain spots
receive almost no signal. Moving out of the
"shadow" of the structure will allow the station
to return to normal.
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.
