ANTENNA
For better AM reception
Following
are
some
hints
for
better
AM
reception.
When receiving weak stations:
When
the
unit
is
tuned
to
a
weak
AM
station,
you
hear
lower
volume
than
when
it
receives
a
strong
one.
If
the
unit
is
used
in
a
concrete
building,
AM
volume
may
be
increased
by
placing
it
by
a
window.
For
best
AM
reception,
you
are
advised
to
install
an
outdoor
AM
antenna.
When hearing AM noise:
AM
noise
can
be
caused
by
one
of
the
following
reasons.
Interference—Interference
causes
an
audible,
high-pitched
beat.
To
avoid
it,
re-align
the
direction
of
the
antenna.
Also
note
that
an
out-
door
antenna
may
also
increase
the
noise
level
of
a
desired
station
by
accidentally
pulling
in
interference
from
other
stations.
Re-alignment
in
this
case
is
also
necessary.
Hum—Booming
hum
noise
is
often
caused
by
the
power
source
and
is
heard
as
60
Hz
(or
50
Hz)
sound.
It
may
be
reduced
by
moving
the
unit
away
from
other
electric
appliances.
Buzz—Buzz
noise
is
caused
by
fluorescent
lamps
and
other
electric
appliances,
or
by
natural
phenomena
such
as
thunder.
Installation
ofa
noise-suppression
device
may
be
effective.
Since
complete
elimination
of
AM
buzz
is
usually
impossible,
it
is
suggested
that
you
make
it
less
audible
with
the
TREBLE
tone
control
on
your
unit.
