AM reception
AM broadcasts can be received at
greater distances than FM broadcasts.
This is because AM radio waves are
transmitted at low frequencies. These
long distance, low frequency radio
waves can follow the curvature of the
earth rather than travelling straight. In
addition, they curve around obstruc‐
tions resulting in better signal cover‐
age.
FM radio station
FM broadcasts are transmitted at high
frequencies and do not bend to follow
the earth's surface. Because of this, FM
broadcasts generally begin to fade
within short distances from the station.
Also, FM signals are easily affected by
buildings, mountains, and obstructions.
This can lead to undesirable or unpleas‐
ant listening conditions which might
lead you to believe a problem exists
with your radio. The following condi‐
tions are normal and do not indicate ra‐
dio trouble:
• Fading - As your vehicle moves away
from the radio station, the signal will
weaken and sound will begin to fade.
When this occurs, we suggest that
you select another station with a
stronger signal.
• Flutter/Static - Weak FM signals or
large obstructions between
transmitter and your radio can dis‐
turb the signal causing static or flut‐
tering noises to occur. Reducing the
treble level may lessen this effect un‐
til the disturbance clears.
