Welcome to QRP Builder

Welcome to my corner of the QRP world. On this site I hope to pass along information, projects, and ideas to the QRP community. The articles will be of a mechanical, or construction nature, as opposed to circuit design.


Be Creative!…  Don’t be a “Passive Consumer” of someone else’s imagination.
