A DIY guide to designing and building transistor radios

Create sophisticated transistor radios that are inexpensive yet highly efficient. Build Your Own Transistor Radios: A Hobbyist’s Guide to High-Performance and Low-Powered Radio Circuits offers complete projects with detailed schematics and insights on how the radios were designed. Learn how to choose components, construct the different types of radios, and troubleshoot your work. Digging deeper, this practical resource shows you how to engineer innovative devices by experimenting with and radically improving existing designs.

Build Your Own Transistor Radios covers:

  • Calibration tools and test generators
  • TRF, regenerative, and reflex radios
  • Basic and advanced superheterodyne radios
  • Coil-less and software-defined radios
  • Transistor and differential-pair oscillators
  • Filter and amplifier design techniques
  • Sampling theory and sampling mixers
  • In-phase, quadrature, and AM broadcast signals
  • Resonant, detector, and AVC circuits
  • Image rejection and noise analysis methods

This is the perfect guide for electronics hobbyists and students who want to delve deeper into the topic of radio.

About the author (2012)

Ronald Quan has a BSEE degree from UC Berkeley and is a member of SMPTE, IEEE, and the AES. He has worked as a broadcast engineer for FM and AM radio stations. For over 30 years he has worked for companies related to video and audio equipment (Ampex, Sony, Monster Cable, and Macrovision). His work included the design of wideband FM detectors for an HDTV tape recorder at Sony Corporation and a twice-color subcarrier frequency (7.16 MHz) NTSC vector-scope for measuring differential phase and gain for Macrovision, where he was a Principal Engineer. Currently he holds at least 65 US patents in the areas of analog video processing, low noise audio and video amplifier design, low distortion voltage controlled amplifiers, wide band crystal VCOs, video monitors, audio and video IQ modulation, audio and video scrambling, bar code reader products, audio test equipment, and video copy protection. In 2005 he was a guest speaker at Stanford University's electrical engineering department's graduate seminar, speaking on lower noise and lower distortion voltage controlled amplifier topologies. In November 2010, he presented a paper in amplifier distortion to the Audio Engineering Society's Conference in San Francisco's Moscone Center.
