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

"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.
