NOTE: In the following
steps you
will
be
directed
to label some of the shielded cables
coming from
the T/R
circuit
board. You can use masking tape or
something similar that
you
can easily write
on. This
will
make it easier for you to identify these cables
later. When
you
connect the free
ends of these ca-
bles,
you can remove the tape, if you desire.
(
)
Label
the
cable
coming from Narrow/Out
"NARROW/OUT."
(
)
Label the cable coming from
Wide/Out "WIDE/
OUT."
(
)
Label the cable coming
from TX/In "TX/OUT."
(
)
Label the cable coming from
INJ/In "INJ/OUT."
(
)
Label the
cable coming from BFO/In "BFO/
OUT."
(
)
Refer
to Detail
3-6A Part B
and use
the follow-
ing procedure
to prepare
the
other end
of the
8-wire
cable:
1. Separate the brown,
red, orange,
yellow,
and green wires
(as a group) from
the
rest of the wires
for a length
of
11-1/2".
Then
shorten these wires
by
3".
Now
separate the five
wires from
each other
for a length
of
1".
2. Separate
the
violet
and gray wires
(as a
pair) from the blue wire
for a length
of
8".
Then shorten this 2-wire
pair
by
5".
Now
separate the two wires
from each
other for a length
of
1".
3. Remove
1/4"
of insulation from
the end
of each wire
at this end of the
cable and
prepare the ends.
)
Set the T/R circuit
board aside temporarily.
)
Cut a
24"
length of 8-wire cable Then refer to
Detail 3-6A Part A (Illustration
Booklet, Page
23)
and use the following procedure
to
prepare
one end
of
the
cable:
1. Separate the brown
and
red wires
(as a
pair)
from
the rest of the wires for
a
length of
9".
Then shorten
these wires
by
8".
Now separate the brown and red
wires from each other for
a
length
of
1".
Save
the cut-off 2-wire cable for use
later.
NOTE:
This end of the
cable will
be referred
to
as
"endB."
Connect
the wires at end A of the
8-wire
cable to
the T/R circuit board
as follows. Solder
each wire
to the foil as you connect it
and cut off
any excess
wire end.
( )
Orange wire to hole +
R.
(
)
Blue wire to hole
KEY.
(
)
Green wire to either hole
9V near the
center
of the circuit
board.
Separate the
orange, yellow, green, and
(
)
Yellow wire to hole YEL.
blue wires from the rest of the wires
and
each other for a length of
2".
NOTE: The other wires
at this end of the
cable and
the wires at end B will
be connected later.
Separate the violet and gray wires from
the other wires
and each other for a
(
)
length of
7-1/4".
Then shorten these
wires
by
6-1/2".
Save the cut-off wires
for
use
later.
Locate the brown-red
2-wire cable
you
set
aside earlier. Separate the wires
at one
end
of
this cable for
1"
and
separate the wires
at the
other
end for
1-1/2".
Then prepare
the ends.
4. Remove
1/4"
of insulation from each
wire at this end of the
cable and prepare
the ends.
NOTE:
This end
of
the cable will
be
referred
to as "end A."
Connect the wires
at the end of the 2-wire
cable that
has
the
wires
separated for
1-1/2"
to
the T/R circuit
board as follows. Solder each wire
to the foil
as you
connect it and cut off any excess wire
end.
