TUNING THE RECEIVER ON
THE FREQUENCY MODULATION BAND !yILL REQUIRE MORE
CARE
THAN
ON
THE BROADCAST BAND. A hissinq sound may be
noted when
tuning between
Frequency
Modulation stations. This
is
normal,
and
will
disappear as the station
is
tuned
in.
After
a
station
is located, the
pointer should be
moved back and forth
over
it until the
point
of
quietest
reception and best tone
quality
is found.
Correct
tuning is indicated by
the disappearance of background noise.
Although Frequency
Modulation
stations are heard over great
distances
on
rare occasions, do not expect to
tune in
other
than
your
Iocal
stations.
The nature of Frequency Modulation
transmission
limits
reception
to areas
within the
approximate horizon.
