Preface
This book is written for anyone who dreams of becoming a licensed Amateur Radio operator in India. Whether you are a student, a scout, a hobbyist, or simply curious about the fascinating world of radio communication, this guide will walk you through everything you need to know to pass the Amateur Station Operator’s Certificate (ASOC) examination — both Restricted and General Grade.
Amateur Radio, popularly known as HAM Radio, is more than just a hobby. It is a service that contributes to emergency communication, scientific experimentation, and international goodwill. Thousands of licensed operators across India and around the world use their skills to connect with people, assist during disasters, and explore the science of radio communication.
This book assumes no prior knowledge of electronics or radio. Every concept is explained from the ground up, with simple language, practical examples, and exercises to test your understanding. The content follows the official syllabus prescribed by the Wireless Planning & Coordination (WPC) Wing of the Ministry of Communications, Government of India.
The book is organised into four parts:
Part I — Radio Theory & Practice — covers the core technical topics required for both Restricted and General Grade examinations, from basic electricity to antennas.
Part II — Additional Topics for General Grade — covers advanced topics such as modulation, power supplies, and space communication that are additionally required for the General Grade exam.
Part III — Radio Regulations — explains the Indian and international rules governing amateur radio operation.
Part IV — Morse Code — introduces the Morse code alphabet, timing, and practice methods required for the General Grade Morse test.
Each chapter includes exercises with answers so you can test your understanding as you learn.
I hope this book makes your journey to obtaining a HAM licence enjoyable, straightforward, and rewarding. See you on the bands!
