Understanding Radio Reception
FM stereo will give you the best sound. But FM signals
will
reach
only
about
10
to
40
miles
(16
to
65
km). And, tall buildings or hills can interfere
with FM signals, causing the sound to come and
go.
The range for most AM stations
is
greater than for FM, especially at night.
The longer range, however, can cause stations
to
interfere
with
each
other.
AM can pick up noise from things like storms and power lines. Try reducing
the treble
to
reduce this noise if
you
ever get
it.
AM Stereo means
the
DelcoB system can receive C-QUAM@stereo
broadcasts. Many AM stations around
the
countr use C-QUAM@ to
produce stereo, though some do not. (C-QUAM
4
is
a
registered trademark
of Motorola, Inc.) If your Delco@ system can get C-QUAM@, your
“STEREO” light
will
come on when you’re receiving it.
Be aware that hearing damage from loud noise is almost undetectable
until
it
is
too
late. Your hearing can adapt to higher volumes
of
sound. Sound that
seems normal can be loud and harmful to your hearing. Take precautions by
adjusting
the
volume control
on
your radio to
a
safe sound level before your
hearing adapts
to
it.
