Text-Book on Wireless Telegraphy, Volume II: Valves, Continuous Waves and Radio-Telephony is a classic reference for engineers and students tackling early 20th‑century radio technology.
This edition covers valve technology, high and low frequency amplification, and the rise of radio-telephony, with practical diagrams and explanations.
This volume surveys the principles, designs, and practical applications of vacuum tubes, oscillators, and detectors. It connects theoretical foundations to real-world equipment used in wireless signaling, wave transmission, and reception, offering a detailed look at valve behavior and circuit construction.
- Clear explanations of valve operation, amplification, and rectification in early radio gear.
- Descriptions of receiver and transmitter valves, circuits, and practical design considerations.
- Discussion of continuous waves, radio-telephony development, and earth-current signaling.
- Historical context and evolution of valve technology during the war era.
Ideal for readers of engineering history and practitioners of early wireless technologies who want a grounded, artifact-based understanding of the era’s key components.
