GENERAL.
Because the TD-5 cannot trans-
mit and receive simultaneously,
completely separate installations are
required for the two applications.
The receive unit is mounted inside
the rear of the receiver compartment
in the repeater, and the transmit
unit is mounted inside the exciter
compartment. In both cases, the TD-
5 board is mounted with the dip
switch levers up to allow adjustment.
RECEIVE INSTALLATION.
Attach hookup wires to the TD-5
as in the following table. Connect
the orange wire to the receiver
DISCRIMINATOR output terminal,
and connect the other wires to the
feedthrough capacitors on the com-
partment shield.
Receive Wires for TD-5
TD-5 Repeater Wire
E2 B+ FT Cap. 9" Red
E3 Rcvr Discrim Pad E4 11" Orn
E5 Defeat FT Cap. 8" Brn or Blk *
E6 COS FT Cap. 9¾" Blu
*Also, attach a 5½” brn or blk wire to connect
E7 on COR-5 to the Defeat FT cap at the rear
of the receiver partition.
TRANSMIT INSTALLATION.
Shield Preparation.
The “L” shaped shield for the
transmitter compartment must be
punched or drilled to allow mounting
of the TD-5. Following is a view of
the inside of the right hand side of
the shield, the short section. Match
holes so the TD-5 board mounts flush
with the underside of the flange and
just 1/16 inch from the edge of the
flange as shown. Dimensions are
critical to ensure the fit of the TD-5
(with an electrolytic capacitor at the
bottom) next to the Exciter and with
the capacitor between two Exciter
power wire pads.
MM Caution: TD-5 is static sensitive!
Installing TD-5 Board.
For transmit mode, the TD-5 re-
quires only two wires plus a bus wire
jumper. Install the wires on the
board and check everything over be-
fore mounting the board.
LBe careful not to overtighten the
screws because it is hard to remove the
screws after the repeater is assembled
and the slots will strip out if too much
torque is needed to remove them with the
screwdriver on an angle. It is best to
mount the TD-5 to the partition be-
fore attaching the partition to the
chassis.
a. Install a short jumper of #22
bus wire on the TD-5 board from E12
to E10 in the upper right hand quad-
rant of the board under the area be-
tween the dip switch and the pot.
This switches the board into trans-
mit mode.
b. Install a 4¼” orange wire
from E2 on the TD-5 to the feed-
through capacitor with the orange
wire (orange wire going to the Ex-
citer).
It is best to install the wires coming off
the rear of the board so they tuck down
out of the way of the exciter, under the
TD-5 board.
c. Install a 1¾” black wire from
E7 on the TD-5 to the top lead of a
resistor on the Exciter used as a
terminal.
For the T301 or T304, connect to
E5 (top lead of R37).
For the TA51, connect to R22.

For the TA451, connect to R17.
Check to be sure the resistor was
installed with correct orientation
when the exciter was assembled.
