SW1: Refer
to Detail
3-5D and mount the
rot-
ary
switch (#63-1410)
to the
chassis at SWl
as
shown. Use a
thin control
lockwasher, a
control
flat washer,
and a
control nut. Be sure
to
position
the switch as
shown before you
tighten the
hardware (note the
positions of the
lugs).
Also make sure
the switch studs
are per-
pendicular to the
subchassis.
(
)
Set the
chassis
assembly aside
temporarily.
Refer to
Pictorial
3-6
(Illustration
Booklet, Page
22)
for the
following
steps.
(
)
Position the
T/R circuit
board as shown
in the
Pictorial.
NOTES:
1. In
the following
steps you
will be
directed
to prepare
wires and
cables and
connect one
end to the
circuit board. The
other ends
of
these wires
and cables
will be connected
later.
2. When a step
directs you
to prepare a
stranded
wire, first cut
the wire to
the indicated
length
and
remove
1/4"
of insulation
from each
end.
Tightly twist together the wire strands
at
each
end. Then melt a small amount of solder on
these ends to hold the
strands together.
( )
Prepare a
7"
large
red
stranded wire. Then con-
nect
and
solder
one
end of the wire
to
circuit
board hole 12V/IN. Cut off any excess wire
end.
( )
Prepare the following shielded cables. They
are listed in
the
order in which
you
will
use
them. NOTE: To prepare these cables, use the
same procedure
that you used when you pre-
pared shielded
cables for the
T/R
circuit
board.

)
3-1/2"
cable: Inner lead
to
hole ANT, shield
wires
to nearby hole GND.

cable: Inner lead
to
hole NARROW/OUT,
shield wires
to
nearby hole GND.
(
)

cable: Inner lead to hole WIDE/OUT,
shield
wires
to
nearby hole GND.
(
)

cable: Inner lead to hole BFO/IN, shield
wires to nearby hole GND.
(
)
13"
cable: Inner lead to hole TX/IN,
shield
wires to nearby hole GND.
(
)
19-1/2"
cable: Inner lead to hole
INJ/IN,
shield
wires
to nearby hole
GND.
(
)
6"
cable: Inner lead to
hole AUDIO/IN, shield
wires to nearby hole GND.
(
)
8"
cable: Inner lead to
hole
AUDIO/OUT,
shield wires
to
nearby hole GND.
