Build Your Own Regenerative Receiver Circuits
Find schematics, designs, and construction guides for regenerative receivers, from simple one-transistor builds to advanced multi-tube projects.
Regenerative receivers offer a fascinating path into radio electronics, allowing hams to build sensitive shortwave receivers with relatively few components. These circuits use positive feedback to amplify signals, making them popular for listening to AM, CW, and SSB signals across various bands. Many operators enjoy the hands-on challenge of designing and optimizing these classic circuits, often achieving excellent performance for their simplicity.
This category provides numerous project plans and schematics for regenerative receivers, ranging from simple one-transistor designs suitable for beginners to more complex multi-tube or modern Armstrong variations. Hams can find detailed instructions for building receivers for the AM broadcast band, shortwave listening, and even VHF frequencies. Projects often include practical advice on construction techniques, fine-tuning for SSB-CW reception, and component selection, helping operators understand the nuances of regeneration.

Regenerative receiver for 5 amateur bands : 80 40 20 17 15m by F5LVG -
A 3.5–24 MHz regenerative receiver for amateur bands was recently constructed, inspired by a 1934 design. The project was both challenging and rewarding, requiring precise tuning and high-quality components. The receiver successfully captured QSOs from across the globe, such as New Zealand communicating with Panama. The simplicity of the design and the satisfaction of building a functional, compact wooden box with handmade resonant circuits were highlights. This project demonstrates a meaningful way to reconnect with the roots of amateur radio. -
