"THE RAMSEY LEARN-AS-YOU-BUILD ASSEMBLY STRATEGY"

Take a look at the parts layout diagram. There is quite a lot to the construction of the QAMP30. It's easier than it seems once you get going, especially after you have installed a few of the "landmark" components. Once these "landmark" components are placed, other parts’ positions are referenced to them, and construction goes quite smoothly. This will help in relating from one part to another what specific holes it may require on the board, and that part's orientation. In addition, we will discuss the purpose of most components or groups of components as we go along. This is the Ramsey Learn-As-You- Build kit assembly philosophy. Be sure to read through all the steps, and check the boxes as you go to be sure you didn't miss any important steps. Most of the problems we find here at the factory are due to faulty assembly, no matter how experienced the builder may be: it’s especially tough to tell a 30 year experienced ham that he goofed! Before you run the circuit, check all diodes and polarized capacitors for proper orientation.

TIPS AND NOTES:

Use a good soldering technique - let your soldering iron tip gently heat the traces to which you are soldering. Heat both wires and pads simultaneously. Apply the solder on the iron, lead, and the pad when pad and wire is hot enough to melt the solder. The actual joint should look like a drop of water on paper (somewhat soaked in).

Parts are mounted on the top side of the board. This is the side that has no traces or pads on it.

Part orientation - All parts in this kit are mounted at 90 degree angles, meaning parts are either parallel or perpendicular to the sides of the board.

Part installation - When parts are installed, the part is placed flat to the board, and the leads are bent on the backside of the board to prevent the part from falling out before soldering. The part is then soldered into place, and the spare leads are removed. Make sure lead lengths are as short as possible when dealing with the RF section of this kit.

CONSTRUCTION:

Since you may appreciate some "warm-up" soldering practice as well as a chance to put some "landmarks" on the PC board, we'll first install some "hardware" components.

In all the following instruction steps, our word "INSTALL" means to do the following:

Insert the part, oriented correctly, into its correct holes in the PC board.
