Assembly - Part I
In Part I, the control, display, and audio stages will be assembled and
tested. Later sections cover receiver (Part II) and transmitter (Part III)
assembly and test.

BEFORE YOU START:
1. WEAR A GROUNDED WRIST STRAP or ground
yourself briefly before touching components. You can
discharge static by frequently touching an unpainted,
grounded metal surface.
2. WEAR EYE PROTECTION before trimming any leads.
3. WASH YOUR HANDS after handling solder. Solder is a
toxic substance.
4. PROVIDE VENTILATION and avoid inhaling the fumes
produced by soldering.
If you haven’t done so already, open the bag of components
labeled KX1 MAIN BAG and sort the parts into groups. Many of the
components will be in small paper envelopes. Do not mingle the
contents of one envelope with another. As you are instructed to locate
particular components, use the photographs in the KX1 PCB parts list
in Appendix A to help identify them.

The components pre-installed on the circuit board are
extremely static-sensitive. Wear a wrist strap or ground yourself
before handling the board.
Position the circuit board on your bench so that KX1 is visible in
the upper left corner. This is the side of the board that will be directly
under the front panel when the transceiver is completed. This side will
be referred to the as the top face of the board throughout the assembly
procedure. Components will be installed on both sides of the board.
Turn the circuit board over so the bottom is facing up and orient
it so the outline for J1 is in the upper right corner. Find the outline for
resistor R8 next to the outline for J1.
