Preparation for Assembly
Overview of the KX1
The KX1 chassis consists of a top and bottom cover (Figure 1). All
components, including controls and connectors, are mounted on a
single printed circuit board (PCB). Only three surface-mount
components are required, and these are pre-mounted to the board.
The top cover is also the front panel. The controls face upward for
convenient operation. The printed circuit board mounts directly behind
the front panel.
The automatic antenna tuner option (KXAT1) plugs into the bottom of
the main PC board at J6, J7 and J8. The optional keyer paddle
(KXPD1) plugs into the Keyer/Paddle jack, J3, at the front edge of the
top cover.
The bottom cover is held in place by two thumbscrews. Two three-cell
AA battery sockets are attached to the bottom cover and are wired in
series to form a six-cell pack. The battery voltage is 7.2 or 9 V
depending on the battery type.
Appendix D provides close-up views of the top and bottom of the
assembled PC board.
