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 generatorsTRF, regenerative, and reflex radiosBasic and advanced superheterodyne radiosCoil-less and software-defined radiosTransistor and differential-pair oscillatorsFilter and amplifier design techniquesSampling theory and sampling mixersIn-phase, quadrature, and AM broadcast signalsResonant, detector, and AVC circuitsImage 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.

I was naive enough to try to build the TRF radio circuit on page 57 in this book. It did not work. It can't work. The NPN transistors in this circuit need to be supplied with 0.7 volts in order to switch on but receive no volts at all. So the radio cannot work. Ronald: you are selling your books on the false premise they are good for hobbyists. This hobbyist tried your circuit and it did not work. Ronald you might have dozens of patents to your name but have you actually tried to build this radio?
