Set
your
VTVM
to
read ac
volts on its lowest scale.
4.
Then connect the VTVM
leads to the loudspeaker
terminals. Connect
the
probe
of
the VTVM
to the
white
wire and the common
(ground)
lead of
the
VTVM to the black wire.
(
)
Turn
on the signal
generator
and the VTVM.
Then
allow
5
minutes to
elapse before
you
start
the
alignment
steps.
Align the Receiver
by
performing
the steps
in the
"Alignment
With Instruments Chart."
The
following
numbered
paragraphs
explain
the first
step
in the chart
and
will
serve
as an example of how to
perform
the other steps:
1. Set the
Receiver
BAND SWITCH at
D.
Set
the
signal
generator
at 11
MHz. Adjust it to the
minimum useable signal
level. Be
sure
to turn on the
modulation of the signal
generator.
Set
the MAI N TUNING of the
Receiver so the
pointer
is at 11 MHz.
ALIGNMENT
CHART
Refer to
Figure
2 and
identify
L4
and L7. Then use
the alignment tool and adjust L4
for the loudest
signal
(highest
VTVM reading). lf
you
do not hear the signal
generator
at the
first
setting, tune
the Receiver to each
side of the 11
MHz
setting and
find
the
generator
signal.
Then turn the coil core in the direction which
will move the signal to
the
11
MHz
position
on
the
tuning scale.
Adjust L7 for maximum signal
as heard on
the
loudspeaker and seen on the
VTVM scale.
Note that
small changes in signal strength
are more easily
detected by the meter than by
your
ear.
Perform each step
in the chart
carefully.
Repeat the steps as necessary.
Then disconnect and
shut off the VTVM and
the signal
generator.
