"Bouncing Signals" dives into the fascinating world of long-distance radio communication using skywaves. These signals bounce off the ionosphere, Earth's invisible layer charged with particles. The book explains how this ionosphere acts like a mirror, reflecting radio waves back to Earth, allowing signals to travel far beyond the horizon. You'll also learn about ionospheric sounding, a technique to understand the ever-changing ionosphere and predict how well your radio signals will bounce. Whether you're a ham radio operator, a radio enthusiast, or just curious about how long-distance radio works, "Bouncing Signals" will guide you through the science and practical applications of skywave propagation.
