Build Your Own Transistor Radios

Preface

Ever since the invention of amplitude-modulated (AM) radio during the beginning of the twentieth century, there has been a unique interest on the part of hobbyists to build various types of receivers from the crystal radios of that era in the 1900s to the software-defined radios (SDRs) in the twenty-first century. In between the crystal receivers and SDRs are the tuned radio-frequency, regenerative, reflex, and conventional superheterodyne receivers. This book will cover these types of radios from Chapters 5 through 11. Chapter 12 will illustrate two types of front-end circuits for SDRs using analog and sampling methods to generate I and Q signals.

This book actually has two personalities. The first 12 chapters are organized as a do-it-yourself ...
