Understanding Radio Reception
FM Stereo
FM stereo will give you the best sound. But FM signals
will reach only about
10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with
FM signals, causing
the sound
to come and go.
AM
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.
