all in one unit. As with all RF circuitry, we want to mount the parts AS LOW
AS POSSIBLE to the board. A 1/4" lead length on a resistor not mounted
close to the board can act as an inductor or an antenna causing all sorts of
problems in your circuit. Be aware though that there are stand up
components in your circuit. They don't need to be squished to the board.
Keep the portion of the resistor or capacitor closest to the board mounted
right on the board.
For each part, our word "Install" always means these steps:

1. Pick the correct part value to start with.

2. Insert it into the correct PC board location. Make sure the part is
mounted flush to the PC board unless otherwise noted.

3. Orient it correctly. Follow the PC board drawing and the written
directions for all parts - especially when there's a right way and a wrong
way to solder it in. (Diode bands, electrolytic capacitor polarity, transistor
shapes, dotted or notched ends of IC's, and so forth.)

4. Solder all connections unless directed otherwise. Use enough heat
and solder flow for clean, shiny, completed connections.

Trim or Nip all excess wires extending beyond each solder connection
taking care that wire trimmings do not become lodged in PC-board
solder connections.

WARNING: Use only solder approved for electronics work or
rosin core solder. Using plumbers solder or acid core solder will
destroy your kit and void your warranty.
Let's begin by sorting out our components and cross-checking them against
the parts list to make sure we have received everything.
IMPORTANT NOTE! The surface mount parts in your kit have
been preinstalled for you. Please do not call the factory for your
missing parts; simply look over the board over and you'll find
them already soldered into place.
