RADIO SOuRCE
notes on radio reception
Your radio will be subject to certain
phenomena that are not encountered
by domestic systems.
The reception of AM and FM signals
may suffer from interference,
which is caused by the nature and
propagation of the signals and does
not reflect on the quality of your radio
installation.
In AM, the reception may be affected
when passing under power lines or
bridges, or when travelling through
tunnels.
In FM mode, the reception may be
affected by the distance from the
station transmitter, the reflecting of
signals off obstacles (mountains,
hills, tower blocks) and
blackspots (no coverage from the
station transmitter).
