Multipath
is an effect similar to television ghosting; it
distorts the received
signal and also causes poor stereo
separation and noise. As shown
in the figure, radio waves
which travel directly from the transmitter to the receiving
antenna are mixed with waves which are reflected off
nearby objects such as buildings. Because the path taken
by the reflected waves is longer than the direct path, the
time required for the waves to arrive at the antenna is also
longer. The mixing of the directly received signal and the
delayed signa! noticeably degrades reception quality.
Multipath interference can be greatly reduced by the use
of a high-quality directional antenna oriented
in the pro-
per direction.

|f power is turned off while a station is tuned in, the
same station will be tuned in automatically when power
is turned on again. Even if the power cord is pulled out
rather than the power key being turned off, the effect
is the same,

When the FM/AM
key is changed from FM to AM,
the last AM
station listened to will automatically be tuned
in again.
In the same
way, when
the key is changed
from
AM
to FM, the last FM station will be tuned
in
again.

pressed no station may be tuned in even though the
frequency display is lit.
