Since this is a “professional” transmitter, we sincerely hope you put this
together in a professional manner. This project will not work as well as you
wished if you just slap it together without following good assembly techniques
and follow all instructions. No matter how clear we may think our manual is, if
you have any questions give us a call at the factory. We will be happy to help
you with any problems you may run into.
This is a mixed signal project meaning there is digital, audio, and RF circuitry 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 closest to the board mounted right on the board.
For each part, our word "Install" always means these steps:
FM100B ASSEMBLY
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.
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 FM100B have
been preinstalled for you. Please do not call the factory for your
missing parts; simply turn the board over and you’ll find them
soldered into place.
