AM and  FM radio signals  are broadcast
from  transmitter  towers  located around
your  city.   They  are  intercepted by  the
radio antenna on  your car. This signal is
then  received by  the  radio and  sent  to
your car speakers.
When a strong  radio signal has reached
your vehicle,  the precise  engineering of
your audio system ensures the best pos-
sible  quality  reproduction.  However,   in
some  cases  the signal  coming  to  your
vehicle may not be strong and clear. This
can  be due  to  factors such  as  the dis-
tance from the radio station, closeness of
other  strong radio  stations  or the  pres-
ence of  buildings, bridges or  other large
obstructions in the area.
This  is  because   AM  radio  waves  are
transmitted  at   low  frequencies.  These
long, low frequency  radio waves can fol-
low the curvature of the earth rather than
travelling  straight   out  into   the  atmos-
phere.  In  addition,   they  curve  around
obstructions so that they can provide bet-
ter signal coverage.
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  at
short  distances  from  the  station.  Also,
FM signals  are easily  affected by  build-
ings,  mountains,  or  other  obstructions.
These can result in certain listening con-
ditions which might lead you  to believe a
problem  exists with  your  radio. The  fol-
lowing conditions are  normal and do not
indicate radio trouble:
AM   broadcasts   can   be   received   at
greater distances than FM broadcasts.
