modulation.º Signal modulation is a process radio
stations use to increase their strength/volume
relative to other stations.
²Terrain. Hills, mountains and tall buildings
between your vehicle's antenna and the radio
station signal can cause FM reception problems.
Static can be caused on AM stations by power
lines, electric fences, traffic lights, driving under
bridges and thunderstorms. Moving away from an
interfering structure (out of its ªshadowº) returns
your reception to normal.
²Station overload. Weak stations are sometimes
captured by stronger stations when you pass a
broadcast tower. A stronger station may
temporarily overtake a weaker station and play
while the weak station frequency is displayed.
The audio system automatically switches to single
channel reception if it will improve the reception of
a station normally received in stereo.
