Radio Hook-Ups: A Reference and Record Book of Circuits Used for Connecting Wireless Instruments (Classic Reprint)

Practical circuits for wireless work—clear diagrams, notes on results, and a focus on usefulness.

This edition presents the most practical diagrams for receivers, amplifiers, trans- mitters, oscillators, and measuring apparatus. It emphasizes notes on results and a complete record of the comparative merit of different circuits, helping experimenters track what works best for their setups.

• Hands-on diagrams for crystal and Audion receivers, damped and undamped waves, and various coil and transformer configurations.
• Guidance on tuning, coupling, and adapting circuits to different wavelengths with practical notes.
• Sections that explain how to record results, compare circuit performance, and reproduce successful arrangements.
• A catalog-style listing of circuits and measurement techniques for testing antenna, wavemeter, and transformer behavior.

Ideal for hobbyists, students, and early radio experimenters seeking ready-to-build, tested layouts and a reliable reference.
