Can We Build George Dobbs’ Signal Generator From Scratch? | Homebrew Ham Radio Podcast

Can We Build George Dobbs’ Signal Generator From Scratch? | Homebrew Ham Radio Podcast

In this episode, we gather around the workbench to look back on our latest homebrew scratch-build project: George Dobbs’ signal generator. Join us as we discuss the design process, parts selection, challenges, lessons learned, and what it took to bring this ham radio project to life from the ground up.

If you enjoy QRP, portable operations, electronics, and building your own gear, this episode is for you. We also announce our next scratch-build project, so be sure to follow along as we continue building, experimenting, and learning together over the coming episodes.

This episode wraps up the signal generator build and kicks off the next project in our ongoing scratch-build series.
