DESCRIPTION
1. RADIO WAVE BAND
The radio wave bands used in radio broadcasting are as follows:
LF: Low Frequency
MF: Medium Frequency
HF: High Frequency
VHF: Very High Frequency
2. SERVICE AREA
(a) There is a great difference in the size of the service areas
for AM and FM broadcasting. Sometimes an FM stereo
broadcast cannot be received even though AM can be re-
ceived very clearly.
FM stereo has the smaller service area, it also picks up
static and other types of interference (ºnoiseº) easily.
3. RECEPTION PROBLEMS
HINT:
Besides the problem of static, there are other problems, such as ºphasingº, ºmultipathº and ºfade outº. These
problems are caused not by electrical noise but by the nature of the radio waves themselves.
(a) Phasing
Besides electrical interference, AM broadcasts are also
susceptible to other types of interference, especially at
night. This is because AM radio waves bounce off the ion-
osphere at night. These radio waves then interfere with
the signals that reach the vehicle's antenna directly from
the same transmitter. This type of interference is called
ºphasingº.

The sections shown in the figure below are filled with foamed material to provide noise insulation.
After repairing these sections or their peripheries, refill with foamed materials
HINT:
1) Use the service holes located on the reverse side of the body panel to refill with foamed materials.
2) When handling foamed material, follow the directions of the material's manufacturer.
