pieces
approximately
5/8"
from
the
bend.
Measure
from
the
flattened
loop
at
this
end
to
a
point
47"
and
beng
the
remaining
length
back
along
itself.
Tie
«
a
knot
with
these
two
pieces
to
form
a
small
loop.
The
length
of
this
flat-
tened
loop
is
not
critical
--
1/4"
will
suffice.

To
“install
the
dial
string,
place
the
first
loop
over
and
behind
the
pulley
on
the
carrier
to
the
left
of
the
pointer.
There
is
ample
space
between
the
pulley
and
the
carrier
to
accept
this
string.
.
With
the
carrier
in
the
far
right
position,
run
the
dial
string
to
the
left
over
and
around
the
front
pulley
(in
the
upper-left
corner
of
the
subpanel)
back
and
in
the
pulley
on
the
carrier
from
bottom
around
right
side,
off
the
top
to
the
left.
Continue
to
the
top
of
the
rear
pulley,
down
the
left
side
of
the
subpanel,
around
the
lower
brass
spacer
bushing
in
lower
left
corner.
The
rest
of
the
length
runs
to
the
right
to
the
pin
on
the
inductor
shaft.
Pass~the
string
below
the
shaft
and
place
the
loop
over
the
pin
in
the
shaft.
Now
rotate
the
inductor
shaft
counter
clockwise
to
take
up
the
slack
in
the
string.
Turning
in
this
direction
will
cause
the
pointer
mechanism
to
move
to
the
left.
‘Turning:
clock=
wise
will
allow
movement
to
the
right
by
the
pull
of
the
elastic.

To
calibrate
the
slide
rule
dial
with
the
variable
inductor,
rotate
the in-
ductor
shaft
clockwise
until
the
pointer
is
at
the
"30"
position
on
the
scale.
This
the
position
for
minimum
inductance.
Holding
the
inductor
extension
shaft
fixed
(hold
by
gripping
the
flexible
coupler)
adjust
the
variable
in-
ductor
so
that
the
contact
pulley
is
at
the
extreme
rear
position
and
against
the
stop
on
the
coil.
Be
sure
that
the
contact
pulley
groove
straddles
the
coil
wire.
Now
tighten
the
set
screw
in
the
bushing
to
the
inductor
shaft.

1.
Connect
pilot
lamps
with
small
hookup
wire.
All
lamps
are
connected
in
paral-
lel
with
common
chassis
ground.
Jumper
and
solder
a
lead
between
the
termi-
nals
of
sockets
and
a
single
lead
to
the
center
terminal
lug
of
the
12
V
dc
jack
on
the
rear
panel.
Route
along
left
side
of
chassis.

2.
Install
the
three=wire
cable
assembly
between
the
SWR
board
on
the
rear
panel’
and
the
switch
board.
Connect
either
female
connector
to
the
3-position
con-
nector
on
the
SWR
board.
Note
that
there
is
a
tapered
lip
on
one
face
of
the
Cable
connector.
This
engages
the
matching
ridge
on
the
vertical
portion
of
the
connector
on
the
board.
This
provides
proper
polarization
and
locking.
The
other
end
of
this
cable
connects
in
like
fashion
to
the
3-position
con-
nector
left
rear
of
switch
board.
Route
along
left
side
of

solder
the
red
lead
to
the
positive
(+)
meter
terminal
and
the
Orange
lead

wire
between
the
meter
terminals.
Note
that
sponge
pads
have
been
attached
to
the
rear

Assemble
the
lexan
plastic
front
panel
to
the
painted
aluminum
front
panel.
CAUTION:
Carefully
inspect
both
of
these
panels
for
appearance.
Clean
the
painted
front
of
the
aluminum
panel
and
both
sides
of
the
plastic
panel.
Any
smudges
orgrease
marks
(finger
prints,
etc.)
will
be
locked
in
for
the
Ltre
Of
this
unit.“
Use
‘a
soft’
cloth
dry
or
with
soap
or
detergent
that
will
not
attack
the
plastic.
Now
align
these
two
panels
so
that
all
holes
match.
Fasten
together
by
inserting
the
two
bosses
on
the
rear
of
the
plastic
T-T
logo
emblem
through
the
two
holes above
the
"antenna"
switch
shaft.
When
properly
aligned
heat
seal
the
bosses
with
hot
soldering
iron.
This
plastic
softens
at
a
much
lower
temperature
than
the
material
in
the
flexible
coupler.
Proceed
with
caution.
