‘Following are some hints for better AM reception.
RSE
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.
Note
that
an
outdoor
antenna
may
increase
the
noise
level
of
a
desired
station
by
accidentally
pulling
in
interference
from
other
stations.
Re-
alignment in this case is necessary.
Hum—Booming
hum
noise
is
often
caused
by
the
power
source
and
is
heard
as
60Hz
(or
50Hz)
sound.
It
may
be
reduced
by
moving
the
unit
away
from
other
electric
appliances.
Proper
grounding
may
also
be
effective
in
reducing
hum.
Buzz—Buzz
noise
is
caused
by
fluorescent
lamps
and
other
electric
appliances,
or
by
natural
phenomena
such
as
thunder.
Installation
of
a
noise-suppression
device
may
be
effective.
Since
complete
elimination
of
AM
buzz
is
usually
difficult,
it
is
suggested
that
you
make
it
less
audible
with
the
treble
tone
control
on
your
amplifier.
