RADIO RECEPTION
Your radio receives signals whilst on the
move, and may experience widely
differing reception characteristics.
Because of this, some interference is to
be expected from time to time during a
journey.
FM transmitters can only broadcast over
a limited range, and good clear signals
will only be received in the immediate area
of the transmitter. When travelling,
occasionally it may be necessary to
re-tune the radio to offset the effects of
moving from one transmitter area to
another.
While automatic re-tuning helps to reduce
the effects of signal changes, some
manual re-tuning may still be required
(especially for local stations) in areas of
weak reception.
The broadcast range for good stereo
reception is within approximately
48 - 64 km (30 - 40 miles) of the
transmitter.
FM Signals travel in a straight line, so
large obstacles, such as tall buildings,
can shield the car from the signal causing
distortion or loss of reception (known as
dead spots).
Distortion can also occur if FM signals
received directly from the transmitter, mix
with signals deflected by obstructions
such as mountains, hills, and tall
buildings. This is known as multi-path
distortion.
Note: Although distortion, interference
and lack of signal clarity are sometimes
attributed to a fault in the radio, this is
rarely the case.
