From the birth of the thermionic valve to the rise of radiotelephony, a clear history of invention and application. This volume explains how high‑vacuum and gas‑relief valves changed wireless communication, with a practical focus on detectors, amplifiers, and oscillators. You’ll see how researchers and engineers shaped the devices that powered early radio, including the Fleming valve and the three‑electrode valve, through diagrams, tests, and real‑world use.

The book frames the evolution of thermionic devices in accessible terms, showing how each design solved problems of amplification, detection, and generation of oscillations. It describes key concepts, notable circuits, and the movers behind pivotal advances, helping readers understand both the science and the engineering behind early radio.

What you’ll experience
- A historical arc from simple detectors to complex amplifiers and oscillators
- Explanations of valve behavior, vacuum levels, and gas ionization in practical terms
- Descriptions of important valve types and how they were used in radiotelegraphy and radiotelephony
- Insights into the experimental methods and circuits that informed early wireless technology

Ideal for readers of technical history and anyone curious about how early radio came to life, this edition sheds light on the people, ideas, and experiments that built the foundations of modern wireless communication.

Paperback. Zustand: New. Print on Demand. This book delves into the fascinating evolution of wireless communication, tracing its roots back to the pioneering work of scientists like Edison and Hertz. The author, a renowned expert in the field, guides readers through the development of various detection devices, from the early coherers and magnetic detectors to the revolutionary thermionic valve. The narrative unfolds against the backdrop of pivotal scientific discoveries, including the exploration of the Edison Effect and the groundbreaking research on thermionic emission by J.J. Thomson and O.W. Richardson. These advancements paved the way for the invention of the Fleming oscillation valve, a device capable of rectifying high-frequency currents and detecting electromagnetic waves. The book explores the valve's application in radiotelegraphy and telephony, highlighting its ability to amplify signals and generate oscillations. It delves into the technical intricacies of different valve types, including the three-electrode valve and the dynatron, explaining their operation and significance. Readers will gain insights into the challenges and triumphs of early radio technology, including the impact of atmospheric disturbances and the quest for improved selectivity and sensitivity. By illuminating the scientific principles and historical context behind thermionic devices, this book offers a valuable resource for understanding the foundations of modern wireless communication and appreciating the ingenuity of those who made it possible.
