Inspect the end of each connector. You should see the contact

pressing up against the end as shown in

Figure 27

. If necessary, press the

contact in from the rear until it reaches the end. If you don’t get the
contact pushed all the way in so it locks over the end of the spring, it
will not make reliable contact with the mating connector.

Orient the housings with dimpled side up so that the red and black

housings are over the colors marked on the PCB exactly as shown in
Figure 28. Be sure the housings are oriented as shown. If they are
upside down they will not mate to the connectors on the power cord.

Figure 28. Orienting J7 on the RF PCB.

Look closely at the sides of the housings. Each has a small tongue on

one side and a groove on the other. Slide the two shells together engaging
the tongue in the groove. Be sure they are fully meshed. No roll pin is
needed to lock the shells together.

Bend the copper wire at right angles to the housings so that when

it is placed in the holes on the PCB, the housings lie against the PCB
within their outline as shown in Figure 28. Be sure the red housing is
on the

+

side and the shells are oriented as shown.

Solder the wires in place and cut them as close to the PCB as

possible.

Cut a 3/4” length of the 16 gauge tinned wire.

In the upper left quadrant, solder the wire in the pad marked with

an antenna symbol so that 1/2 inch of the wire sticks up vertically (see
Figure 29). Trim the wire as close as possible to the bottom of the
PCB.

Unwrap the cabinet back panel. That is the panel with a row of

holes for the connectors.

Good electrical contact between all of the chassis parts is

essential for optimum shielding and system noise figure.

Remove paint overspray from the inside surface of the cabinet

back panel in the following locations. Sandpaper is provided for this
purpose.

Around the four screw holes for the

ANT

connector.

Around the two screw holes for the

CONTROL

connector.

Around the four screw holes at the corners of the back panel.
