Chassis wiring:
Picture 4 shown below shows how the board to chassis wiring should look like. Note that the wires are made long enough so that there is
some slack, but not so long as to be sloppy. Except for the antenna connections, the wires connecting to the real panel are routed along the
side of the board, rather then above and across it.
●
Mount the front panel parts first. Tuning cap, RIT and Volume control and Digital Dial. Bend or remove anti-rotation tabs on pots.
●
The BNC antenna jack wires from the board should be soldered to the board before the board is mounted into the case.
●
You can cut the rest of the wires to length and solder them to the board out side the case, or you can mount the board into the
case and solder the wires on to the board from the top.
●
Wire up the front panel controls. Use the #24 magnet wire between the board and tuning cap.
●
Install the rear panel jacks and wire them up.
●
A ground wire isn't required to the Digital Dial as the cabinet acts as the return path, but one can be added between the two boards
at the “G” pad near L3.
Microphone jack is shown wired so
PTT is tip and mic element is ring.
This allows using straight key or keyer
with standard mono phone plug
attached.
