HOW TO INSTALL WIRING FOR TD-5 IN REP-200 REPEATER HOW TO INSTALL WIRING FOR TD-5 IN REP-200 REPEATER
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.

and connect the other wires to the
feedthrough capacitors on the com-
partment shield.

of the receiver partition.

screws because it is hard to remove 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 b e-
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.
