THE DRIVING HABITS OF AM AND FM RECEPTION

Although you may be familiar with both AM and FM reception In your home, you will experience
notable differences In reception while driving your car. This page will explain why these
variances occur and how they affect the broadcast you are listening to .

Both AM and FM provide excellent listening enjoyment and supply the diversified entertainment
necessary to relieve the boredom of hours "behind the wheel" of you car FM reception although
unique In Its characteristics while driving, provides a totally new sound experience unlike AM
reception. The clarity ottone, the richness of sound and the varied program content provide
hours of uninterrupted listening enjoyment. The few reception Inconveniences common to FM are
compensated by the many plus features of a sound experience rivaled only by a live sound
performance

Your new AM-FM radio or radio-tape system has been buiit to the strictest engineering standards
avaiiabie today and through quaiity components and construction wiii provide maximum perfor.
mance under all conditions A few minutes reading this page will enable you to obtain the most
from FM reception and provide answers to your questions about the differences between AM and
FM operation while driving in your car

Some facts about AM and FM reception:

1 RECEPTIONINTUNNELS

Although you will lose AM reception when driving through tunnels and under large bridges, it is
common to continue to receive FM reception.

2 THENUMBER 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. RECEPTION 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
Passing 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
eception 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 cuw'e 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 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 Thr'ough 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 differ'ent reception possibilities. First an
FM signal can "bounce" between tall buildings r'esulting 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
signals.lt is possible to find reception very poor even when you are not far from the FM
Antenna
