Radio Receiver Projects You — Can Build By Homer L Davidson
If you have even a passing interest in vintage electronics, backyard engineering, or the simple magic of pulling a voice out of thin air, Homer L. Davidson’s Radio Receiver Projects You Can Build is a quiet treasure. First published in the 1990s (and still available used), it feels like a time capsule—but not a dusty one. It’s the kind of book that smells faintly of solder and ambition.
- The Feature: A regeneration control that allows you to listen to SSB (Single Sideband) and CW (Morse Code).
- The Challenge: Regenerative radios can oscillate randomly. Davidson dedicates a full troubleshooting section to "taming the squeal," teaching builders how to shield components and use proper grounding.

Homer Davidson was a prolific technical author who penned over 45 books and 1,000 articles on electronics. His teaching philosophy was rooted in "learning by doing"—he believed that by building your own equipment, you gain a deep understanding of fundamental principles like signal processing and amplification that modern "black-box" devices often hide.

Check your local library's interlibrary loan or search eBay for "TAB 3020" (a common ISBN for the edition). Then, order a grab bag of 2N2222s and a spool of magnet wire. The airwaves are waiting. The Feature: A regeneration control that allows you

Uses a movable ferrite core instead of a variable capacitor to change stations. 2. AM and Shortwave Receivers
"Any luck, Eli?" Marcus asked, looking at the chaotic mess of wires and glowing glass on the workbench. "The wife is freaking out. We don't know if the National Guard is coming or if we’re on our own."
