Some facts about AM and FM reception:
1 RECEPTION IN TUNNELS

ing electrical roadside power lines which does not Interfere with FM reception Conversely, FM
may be affected by electrical noise from passing cars or trucks while AM reception is not
5 FM RECEPTION RANGE
FM reception range is usually limited to 50 miles from the broadcast station FM signals
radiate straight out from the broadcast antenna They do not follow earth's curve and are not
reflected back to earth by the atmosphere resulting in lImited "line of sight'. reception range
6 AM RECEPTION RANGE
AM stations can be received several hundred miles from the broadcast station AM sIgnals
follow earth's curve and are easily reflected back to earth by the atmosphere Therefore, an
AM signal is easily received far from the broadcast station antenna
FM RECEPTION WHILE YOu ARE DRIVING
Since FM signals become weaker the further you drive away from the broadcast station you
will experience flutter, nolsy reception and fading In the poor signal fringe area Through the

area Even with this Improved circuitry. eventually the FM signal will become too weak to pro.
VIde Quality reception When this occurs It IS best to change to a stronger. local FM station
Although FM signals are not reflected by the atmosphere they are easily reflected by solid ob.
jects This effect of FM signals pr:>vldes two totally different reception pOssibIlities First, an FM
sIgnal can "bounce" between tall buildings, resulting In unexpected reception In many areas
where AM reception is Impossible
The same effect can result In the "loss" of an FM signal If a large obstruction IS located bet-
ween you and the FM antenna II hills or buildings between you and the antenna block the SIg-
