(c) Radio reception problems
HINT:
In addition to static, other problems such as "phasing", "multipath" and "fade out" exist. These problems
are not caused by electrical noise, but by the radio signal propagation method itself.
(1) Phasing
AM broadcasts are susceptible to electrical interference and
receives 2 radio wave signals from the same transmitter.
One signal is reflected off the ionosphere and the other
signal is received directly from the transmitter.

(2) Multipath
One signal is reflected off buildings or mountains and the
other signal is received directly from the transmitter.

Multipath
(3) Fade out
Fade out is caused by objects (buildings, mountains and
between the transmitter and vehicle. High frequency radio
waves, such as FM broadcasts, are easily deflected by
obstructions. Low frequency radio waves, such as AM
broadcasts, are less likely to deflect.

(d) Noise problem
Technicians must have a clear understanding about each customer's noise complaint. Use the following
table to diagnose noise problems.
RADIO
FREQUENCY
NOISE OCCURRENCE CONDITION
PRESUMABLE CAUSE
AM
Noise occurs in a specific area
Foreign noise
Noise occurs when listening to an
intermittent broadcast
An identical program transmitted from multiple towers
can cause noise where the signals overlap
Noise occurs only at night
Signal phasing
FM
Noise occurs while driving in a
specified area
Multipath resulting from a change in FM frequency
6. "HD Radio" FUNCTION OUTLINE (w/ HD Radio Function)
(a) The "HD Radio" system is a radio system that broadcasts in the IBOC (In-Band On-Channel) form that the
"HD Radio" technology is manufactured under license from iBiquity Digital Corporation. U.S. and Foreign
Information for the music currently being listened to is stored in the system and can be transmitted to an
"iPod" connected to the system. ("TAGGING") The information transferred to the "iPod" can be used for
purchasing the music through the "iTunes" music store. Also, traffic and weather information can be
