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 your radio.
FM Stereo
FM stereo gives the best sound, but FM signals reach
only 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.
