7-42. Solder the RED wire from "LED1" on the receiver board
to the insulated ANODE (longer) lead of LED1.
7-43. Solder the BLACK wire from "LED1" on the receiver
board to the remaining CATHODE lead of LED1.
7-44. Secure the two long speaker wires at their midpoint
with a cable tie.
7-45. Gather the six wires to "Vcc Batt," "Vcc Ext" and
"AUDIO OUT" and bundle them with a cable tie about 1" from
the "Vcc Batt" connections on the board.
7-46. Attach the last cable tie around the four wires to the
battery shelf assembly and external DC power jack, positioning it
about 1.5" from the cable tie installed in step 7-45.
7-47. If you did not do so already, mount the 1/4" phone jack
on the rear panel, with the flat washer between the panel and
nut.
At this point, all receiver wiring is completed, and you
are ready to make the only final adjustment required, a
careful setting of the R6 regeneration trimmer. Do NOT
mount the battery shelf assembly yet, as it would block
access to the R6 trimmer.
7-48. Use the correct size allen wrench to install all front
panel knobs, if you have not done so already. The alignment of
knob stripes to front panel markings should be very obvious.
Make sure the Main Tuning knob has clearance from the front
panel and does not rub against it.
7-49. Prepare the receiver for testing as follows:
Set DC power switch to OFF: install 8 "C" cells in
battery shelf assembly OR connect 12-15VDC to the
rear panel.
Connect antenna wire to rear panel antenna terminal.
If the antenna feedline is coax, connect the shield
of the feedline to GROUND. If not, it may be necessary
to make an earth ground connection to GROUND in order
to properly evaluate higher-frequency performance.
