Radio reception
Usually, the problem with radio reception does not mean
there is a problem with your radio – it is just the normal
result of conditions outside the vehicle.
For example, nearby buildings and terrain can interfere
with FM reception. Power lines or telephone wires can
interfere with AM signals. And of course, radio signals
have a limited range. The farther you are from a station,
the weaker its signal will be. In addition, reception
conditions change constantly as your vehicle moves.
Here are some common reception problems that
probably do not indicate a problem with your radio:
FM
Fading and drifting stations – Generally, the effective
range of FM is about 40 km (25 miles). Once outside this
range, you may notice fading and drifting, which
increase with the distance from the radio transmitter.
They are often accompanied by distortion.
Multi–path – FM signals are reflective, making it
possible for two signals to reach your antenna at the
same time. If this happens, the signals will cancel each
other out, causing a momentary flutter or loss of
reception.
Static and fluttering – These occur when signals are
blocked by buildings, trees, or other large objects.
Increasing the bass level may reduce static and
fluttering.
