2 THE NUMBER OF STATIONS IN YOUR AREA
Depending upon your location you will usually find the number of AM stations In your area
outnumber the number FM stations, although the continuing popularity of FM reception has
significantly Increased the number of FM stations nationwide.
3. RECERTION DURING STORMS
Local electrical thunderstorm activity often produces sharp static sound when listening to AM
stations although you will find that FM Is unaffected
4. ELECTRICAL INTERFERENCE
When listening to AM stations, you may experience some buzzing sounds or static when
Rassing 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 r
eceptlon Is not.
5. FM RECERTION 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 RECERTION RANGE
AM stations can be received several hundred miles from the broadcast station. AM signals
foilcw the 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, noisy reception and fading In the poor signal fringe area Through the
modern circuitry In this radio, this "Fringe Area" has been greatly reduced for greater
reception area. Even with this Improved circuitry eventually the FM signal will become too
weak to provide 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
objects. This effect of FM signals provides 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. If hills or buildings between you and the antenna block the
slgnals.lt Is possible to find reception very poor even when you are not far from the FM
antenna
