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 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.
