RAMSEY "Learn-As-You-Build” KIT ASSEMBLY
There are solder connections on the DA25 printed circuit board. Therefore,
PLEASE take us seriously when we say that good soldering is essential to the
proper operation of your discone antenna kit!
• Use a 25-watt soldering pencil with a clean, sharp tip.
• Use only rosin-core solder intended for electronics use.
• Use bright lighting; a magnifying lamp or bench-style magnifier may
be helpful.
We have a two-fold strategy for the order of the following kit assembly steps.
First, we install parts in physical relationship to each other, so there's minimal
chance of inserting wires into wrong holes. Second, whenever possible, we
install in an order that fits our "Learn-As-You Build" Kit building philosophy.
This entails describing the circuit that you are building, instead of just blindly
installing components. We hope that this will not only make assembly of our
kits easier, but help you to understand the circuit you’re constructing.
For each part, our word "Install" always means these steps:
1. Pick the correct component with the proper value to start with.
2. Insert it into the correct PC board location.
3. Orient it correctly, following 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.
4. Solder all connections unless directed otherwise. Use enough heat
and solder flow for clean, shiny, completed connections.
5. Trim or nip the excess component lead wire after soldering.
