Radio Reception

You may experience frequency interference and
static during normal radio reception if items
such as cellphone 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 will 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.
