Side panel drilling dimensions:
Below the dimensions shown in the Y axis are referenced to the bottom of the
board. To this one would have to add the thickness of the board (0.061”) plus the
board mounting spacers and the thickness of the front panel to get the proper Y
distance.
Not knowing the size of the chassis you might use, the dimensions below are
shown from the edge of the board in one axis, and the surface of the board in the
other.
Additional construction note:
There are provisions, as mentioned earlier, concerning J4,5. These are provided
for adding an external speaker, and or, SKC keyer. The mounting holes are
provided for these options in the optional Pacificon Chassis. Mounting instructions
for these additions can be found in the chassis assembly manual. If you exercise
this option, remember to remove the speaker jumper installed earlier. Shown
below are the details for J4,J5 and the optional SKC keyer.
If you are adding the KD1JV SKC Keyer and associated pcb chassis, assemble the
keyer to
Option2 in the keyer instructions. Trim the header plug and wire
assemblies to 5” from the far end of the connector to the ends of the three wires
on each of the two assemblies supplied. Strip and tin about 1/8” of each wire.
Wire the interconnecting pigtails as shown below, and use a piece of the trimmed
pigtail wire to connect the “Function Tone” pad to the speaker jack as shown in
“green”. Mount the main SKC board to the bottom of the chassis where indicated
by the outline, with a piece of two sided foam tape. Secure the speaker jack with
the pins down . Secure the speaker jack and keyer jack to the side pcb using the
threaded rings. Plug the pigtails into the correct header.
