Bridging the gap between theoretical engineering texts and bare-bones service manual, this work covers basic operation, design and troubleshooting aspects of all types of radio-frequency (RF) equipment. Contents include RF amplifier types, frequency mixers and converters, digital tuning for RF voltage amplifiers, procedures for measuring the resonant frequency of LC circuits, the inductance of a coil, transmitter modulation, receiver sensitivity, techniques for localizing trouble in RF circuits, digital tuner troubleshooting and a guide to symptoms and remedies. The book should prove useful to radio technicians, engineers, hobbyists and students.
