Now
install

six-turn
compensating
coil
between
terminals
2
and

of
Sl.
(It
will
help
if
you
spread
the
slots
in
these

to
accomodate
this
large
wire
--
use
an

mounts
so
that
its

is
in

We
are
now
up
to
installation
of
the
feed
through
terminals
Tl
through
T4
along
the
upper
edge
of
the
panel.
You
will
find
eight
black
molded
#10
feed
through
insulators.
The
small
stud
on
the
flat
side
of
each
are
pressed
into
the
small
holes
above
and
below
the
large
holes
in
the
panel.
(Check
to
see
that
the
holes
are
free
of
burrs.
If
not,
clear
with
a
knife
point
or
Grill...).
Start
at
T4. Insert
a
10-32
x 1-1/4"
screw
through
the
#10
in-
ternal
tooth
solder
lug
attached
to
the
lead
wire from
terminal
9
on
Sl.
Place
one
insulator
next
on
this
screw
with
the
bevel
side
of the
insulator
toward
the
solder
lug.
Pass
the
screw
through
the
large
hole
T4.
Pass
the
screw through
another
insulator
with
the
flat
side
toward
the
rear
(painted)
side
of
the
panel.
Run
a
10-32
hex
nut
on
the
screw
to
secure.
CAUTION:
Rotate
both insulator
sections
so
that
the
small
studs
are
in
the
small
holes
-- one
in
upper
and
other
in lower.
This
will
center
the
terminal
screw
in
the
large
clearance
hole
in
the
panel.
Tighten
the assembly.
Inspect
below
Sl
and
dress this
lead
wire
so
that
it
is
located
equally
between
the
switch
wafer
and
the panel and
to the
left
of
the hole
in
the rotor
section.
17. Repeat the above installation for the lead wire from ANT 4 connector to
terminal T2.
(Ys 18. Now attach the single leads from the balun coil in like manner to terminals
1 and 3. This coil will later mount parallel and to the right side panel.
Use Tl for the lead that exits from the right side of the coil. The left
exiting lead will go to T3. The center tap leads and their attached lug at-
tach to the rear panel via the hole above S2. CAUTION: Before mounting this
lug, connect the free lead to it from the capacitor to terminal 1 on S82.
Attach this lug with a 6-32 screw (from the outside), lock washer, and hex
nut. Tighten.
REAR PANEL ASSEMBLY INSTALLATION
(LY 1. Re-examine your handy work in assembling and soldering all points on the in-
side surface of the rear panel. Clear any excessive solder "blobs" or drips
and wire ends that may loosen and cause shorts. Resolder any joints that may
appear questionable -- cold soldered, insufficient solder, excessive solder,
etc. by
(4°2. Position the rotors of Sl and $2 as follows and carefully leave in these po-
Sitions to ease later assembly operations. Note that the double flatted
shaft hole in the center of each rotor has a small notch in the middle of one
flat side. Rotate each rotor by inserting a screw driver or other blade in
the hole so that they are in these positions.
1. Notch on Sl between terminals 3 and 4.
2. Notch on S2 between terminals 12 and l.
(W3. Solder one end of a 2-1/2" piece of teflon covered hookup wire to a #6 solder
lug and attach that lug under the hex nut on the rear mounting screw of the
variable capacitor. This lead will attach to the ground terminal lug on the
rear panel. Solder.
