Radio Reception
Frequency interference and static can occur
during normal radio reception if items such as cell
phone chargers, vehicle convenience accessories,
and external electronic devices are plugged
into the accessory power outlet. If there is
interference or static, unplug the item from the
accessory power outlet.
AM
The range for most AM stations is greater than for
FM, especially at night. The longer range can cause
station frequencies to interfere with each other.
For better radio reception, most AM radio stations
boosts the power levels during the day, and then
reduce these levels during the night. Static can also
occur when things like storms and power lines
interfere with radio reception. When this happens,
try reducing the treble on your radio.
FM Stereo
FM stereo gives the best sound, but FM signals
only reach about 10 to 40 miles (16 to 65 km).
Tall buildings or hills can interfere with FM signals,
causing the sound to fade in and out.
