Schematics are provided separately as image files in the documentation
package, as well as being incorporated into this manual. It is highly
recommended that you print a couple of copies at 11 X 17 inch format at your
local UPS Store, Staples, etc. As you build, use a highlighter to mark off parts
that have been soldered onto the PCB on one copy. When you think you are
done, you can check that copy to verify that all of the parts have been installed.
It is helpful to acquire the necessary tools and supplies before beginning.
These include:
*Soldering iron
– ESD safe, 20-30W, preferably thermostatically controlled.
*Small diameter
(0.025” recommended) 60/40 or 63/37 rosin core solder
*Wire stripper
*X-Acto type hobby knife (#11 blade best)
*Diagonal cutters (flush-cutting type preferred)
*Needle-nose pliers
*Fine file or emery board
*Phillips screwdriver
*Allen wrench: 1.5mm
– for the pointer knob’s set screw
*Hand drill with 1/8” bit
*Non-metallic alignment tool
*Fine jeweler’s screwdrivers
*Electrical tape
*Clear fingernail polish
*Wood glue
*Clamps or spring clothespins
*Magnifier
*Digital volt-ohm-meter
*Calibrated general coverage receiver, 40M CW receiver, or frequency
counter
Soldering is not hard if the proper procedure is followed. The soldering iron is to
be used to heat up the PC pad and component lead, and the solder applied to
the pad, where it melts and flows into the hole. Do not melt the solder onto the
tip of the iron and then attempt to dab it onto the joint
– a defective connection
will result! After soldering, check the top (component side) of the board, to be
sure the solder has filled the hole completely, and wicked up around the
component lead. Re-heat and apply more solder if necessary.
