The Beginner's Handbook of Amateur Radio / Edition 4

by Clay Laster

Overview

This text provides the reader with the necessary electronics background to begin hamming and to help with preparations for the FCC novice or no-code technician class license exam. The first two chapters provide an introduction to amateur radio, the FCC part 97 rules and regulations and how to prepare for the Novice examinations. The following chapters form the basis of a mini-course in electronics technology with an emphasis on radio communications. It covers the basics of wave propagation, power supplies and electronic circuits. This updated edition coincides with the recent changes in the FCC novice examinations, and has over 250 sample questions and answers.
