Radio Receiver Projects You Can Build By Homer L Davidson (2026 Edition)

With just an IC, a tuning coil, and a few capacitors, readers learn to build a pocket-sized radio that rivals commercial units in performance. 4. Shortwave and Specialty Receivers

Reviewers from eBay and Amazon highlight the book's detailed parts lists and its appeal to those interested in "old school" technology. Radio Receiver Projects to Build | PDF | Capacitor - Scribd

: Use modern equivalents if necessary. While germanium diodes (1N34A) are essential for crystal sets, modern silicon transistors can be used in the amplifier stages.

The book typically kicks off with variations of the classic crystal radio. These projects require no batteries or external power supplies.

| Part | Value / Type | |------|---------------| | Q1 | 2N3904, 2N2222, or MPSH10 | | D1 | 1N4148 or 1N34A germanium (better sensitivity) | | L1 | 100 µH RF choke (or 100 turns #28 AWG on T68-2 toroid) | | C1 | 365 pF variable capacitor (AM tuning cap) | | C2, C3 | 0.01 µF, 0.001 µF ceramic | | R1 | 2.2 MΩ (biasing) | | R2 | 100 kΩ | | Earpiece | High-impedance (2 kΩ+) crystal or magnetic type |

Davidson's 33 projects are sequenced progressively, letting the reader's test bench evolve alongside their knowledge. With just an IC, a tuning coil, and

"Simple, robust, and sensitive," Davidson had written in the caption. Elias nodded. "You never let me down, Homer."

When you turn that first dial and pull a station out of the noise—using a circuit you built with your own hands—you will realize that Homer L. Davidson wasn't just teaching you to build a receiver. He was teaching you to listen to the world.

: Provides practical advice on finding parts, making your own PC boards, and troubleshooting non-performing radios. Available Formats and Pricing Radio Receiver Projects to Build | PDF |

Davidson often uses (phenolic board with holes) or Vectorboard .

The book is organized by receiver type, allowing builders to progress from basic to complex designs: Crystal Radio Projects

The tone is warm and no-nonsense, like a favorite shop teacher who stays after school to help you get that oscillator working. Troubleshooting tips are woven throughout. He tells you what to expect: “If you hear a loud hum, reverse the power supply leads.” Real, practical advice.
