PC power supply conversion for ham radio use. Slide show overview showing how convert PC Power supplies to ham radio use presented at the August 2007 FSARC meeting.

The best way to describe a go-box is a complete amateur radio station in a box. An example is described in this article. The project describes building a portable amateur (ham) radio station, known as a "go-box," housed in a durable orange Pelican case. The go-box contains all necessary radio equipment except for external power and antennae, which are carried separately. It includes items like a Yaesu transceiver, power supply, antenna tuner, speaker, and a clock. The case is designed for mobility and visibility, with a vertical layout to allow in-vehicle operation. Future upgrades might include cooling fans, an LED lamp, and built-in antennae for better functionality in various conditions.
