Title: Book - Practical Wireless Telegraphy E. E. Bucher (1917)
Product review: In the era this book was written there were NO transistors, tubes were just starting to be used and the only known bands were above the 200 meter band. Most transmissions were in the 600 meter band. "Welding Machines" were transmitters that is a spark with some interesting methods of generating one and tuning circuits were used to more or less (by todays standards mostly less) control the output frequency. The crystal set was king, few if any had the latest and greatest regenerative sets (patent 1914). For the crystal set enthusiast this is a goldmine of ideas and understanding of very early radio.I would reccomend this book to the crystal set enthusiast or anyone with an interest in early radio. The transmitter circuits are Extremely Dangerous as well as illegal.
