About the book:

Hobbyists, technicians, amateur radio operators, and general radio enthusiasts of all skill levels will find this book beneficial; however, the content is designed primarily with the needs of intermediate to advanced radio electronics technicians and experimenters in mind. For successful completion of the projects, some experience is assumed on the part of the experimenter. Project areas covered include RF circuitry and digital techniques. PC board construction is largely used with some surface mount construction where necessary. A few of the projects also use microcontrollers.

This book contains construction details for audio and video transmitters operating at frequencies from 150 kHz to 1300 MHz for Part 15 operation and for Novice Class Amateur use. Included are several low-power AM and FM audio transmitters, from simple, discrete designs to sophisticated PLL-synthesized types.
This book also offers chapters on a frequency-synthesized AM broadcast transmitter for 150-1710 kHz, two FM transmitter designs for 88-108 MHz stereo operation, using PLL synthesis digital readouts and microprocessor control, several low-power (0.5-2 watt) TV transmitters covering the 440, 900, and 1300 MHz amateur bands, a data transmitter and receiver, and a chapter on video reception techniques for the special frequencies used.
