How Radio Works
Understand the magic behind every transmission.

RadioBook: How Radio Works demystifies the physics, electronics, and principles that make amateur radio possible. From electromagnetic waves to antenna design, this book explains what is actually happening when you press the transmit button — in plain language anyone can follow.
What This Book Covers
- Electromagnetic Waves — What radio waves are, how they travel, and why frequency matters
- Signals and Modulation — AM, FM, SSB, digital modes, and how information rides on a carrier wave
- Propagation Basics — Ground wave, sky wave, line of sight, and what makes signals go farther than you expect
- Radio Circuits — Oscillators, mixers, filters, amplifiers, and the building blocks of every radio
- Antenna Fundamentals — Dipoles, verticals, Yagis, and how antenna design affects your signal
- Power and Efficiency — Watts, dB, gain, and understanding what your radio is actually doing
- Reading the Bands — How the ionosphere, weather, and time of day affect what you can hear and reach
- Practical Experiments — Hands-on activities and demonstrations you can do at home
Who This Book Is For
- New operators who want to understand why their radio behaves the way it does
- Self-taught hams who learned to operate but missed the theory
- Students preparing for licensing exams who need the concepts, not just the answers
What Makes This Book Different
- No physics degree required — Concepts explained with analogies, diagrams, and everyday examples
- Companion game included — Interactive propagation simulator and circuit explorer reinforce the lessons
- Practical focus — Every theory section connects back to something you can observe on the air
