Things You'll Need
Instructions
Obtain a radio kit of your choice. Today there are many kits available over the Internet, ranging from low-power transmitters to full-blown combination communications transceivers. You can purchase any kit from Elecraft or you can search using your favorite search engine for a variety of smaller packaged kits. Be sure the kit you choose is geared for your kit-building level.
Follow all of the instructions that come with your kit. Every kit comes with a circuit board, electronics components, instructions and a chassis. The components must be soldered onto the board using a soldering iron and solder--generally a rosin-core base solder. However, some kit manufacturers may recommend a different type of solder, so be sure to obtain the type recommended so your warranty isn't voided.
Place each electronics component onto the circuit board that came with your kit in the order given in the kit's instructions. If you are placing small components onto the board, use a magnifying glass to see where you are placing each component and use a pair of tweezers to set each into place.
Solder each placed component onto the board. You will need to have at least an average skill in using a soldering iron and solder to ensure a good solder connection of each component onto the circuit board. Solder each component into place and allow to cool briefly, for about ten seconds, before moving on to soldering additional components.
Place the circuit board(s) into the chassis mounts as the kit instructions direct. Screw the boards down tightly, connect wires to the rear panel if instructed to do so, and then place the top cover onto your equipment chassis. Plug in your newly built kit and connect any antennas to the transmitter/receiver unit(s). Follow all testing recommendations and adjustments according to the instructions you received for your particular kit.
