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

As you can see in examining the circuit board and components, there is a bit

more to this kit than just soldering a few parts. So that you don't spend extra

time "troubleshooting" instead of getting on the air, we strongly recommend

that you follow the assembly strategy and step-by-step procedures we pro-

vide.

Our strategy in installing parts on our PC board is to install the larger and

more obvious parts such as the ICs and connectors first. These parts will then

act as "landmarks" so that each additional device installed is seen in relation-

ship to them, or to others previously installed.

In addition, we'll discuss the purpose of most of the components or groups of

components as we go along. If you are new to the idea of building your own

transmitter, perhaps our explanations will help you understand and learn as

we go along. The assembly sequence will follow the circuit flow from input

jacks to antenna as faithfully as is practical, as part of Ramsey's "Learn-As-

You-Build" kit assembly philosophy.

FM25B ASSEMBLY

Use the boxes to check off your progress.

Check all received parts against the Parts list on page 10 and 11. The parts

list describes the various markings that may be found on the kit parts.

Important Note! The surface mount parts in your kit have been prein-

stalled for you. Please don’t call the factory for your “missing” parts;

simply flip the PC board over and you’ll find them soldered into place.

Since you may appreciate some "warm-up" soldering practice as well as a

chance to put some "landmarks" on the FM25B PC board, we'll first install

some "hardware" components, to make the up-down, left-right orientation of

the PC board as clear as possible.

In ALL the following instruction steps, our word "INSTALL" means this:

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

• If helpful, gently BEND the part's wire leads or tabs to hold it in place, with

the body of the part snugly against the top "component side" of the PC

board.

• SOLDER ALL wires or pins of the part, whether the two wires of a resistor

or all pins of an IC socket.
