Reception Guide; Automatic Noise Limiter; Location; Tuning Scale - Heathkit SW-717 Assembly

When tuning
SSB signals,
tune
to
the
SSB
station and then
alternate
between
the BANDSPREAD
and BFO controls
for
the clearest reception.
AUTOMATIC NOISE LIMITER (ANL}
lf
you
experience impulse
type
noise, such
as
automobile
ignition
radiations, move
the {ANL)
switch on the rear
panel
to
ON.
LOCATION
lf
the
Receiver
is used on
band
A (which
uses
the built-in
antenna)
in
a
house
which
has
aluminum
siding,
or
in
a
steel
framed
building, you may find the
signals
attenuated to
some degree. Placing
the
Receiver near
a window in
the
direction
from which
reception
is
desired
may
improve
reception.
TUNING SCALE
A
scale
for
each
of the
four
bands appears
on the
front
panel
as
shown
in
Figure
4.
Each scale is
calibrated in frequency.
Scale
A
frequencies are
in kilohertz
(thousands of cycles per
second).
The other
three
scales
are
calibrated
in
megahertz
(millions
of
cycles
per
second).
A
"log
scale"
is
also
provided for
convenience
in
recording the pointer setting of
stations
for future
reference,
