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 boost 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 the radio.
FM Stereo
FM signals only reach about 10 to 40 miles (16 to 65 km).
Although the radio has a built-in electronic circuit that
automatically works to reduce interference, some static
can occur, especially around tall buildings
or hills, causing the sound to fade in and out.
