Radio signals, especially on the
FM band, are deflected by large
objects such as buildings and
hills. Your radio then receives
both the direct signal from the
station's transmitter and the
deflected signal. This causes the
sound to distort or flutter. This
is a main cause of poor radio
reception in city driving.
Radio reception can be affected
by atmospheric conditions such as
thunderstorms, high humidity, and
even sunspots. You may be able to
receive a distant radio station one
day and not receive it the next day
because of a change in conditions.
Electrical interference from
passing vehicles and stationary
sources can cause temporary
reception problems.
As required by the FCC:
Changes or modifications not
expressly approved by the party
responsible for compliance could
void the user's authority to
operate the equipment.
