Available in PDF, EPUB and Kindle. Book excerpt: This book written by P. A. Kinzie chronicles the fascinating history and development of the crystal detector, including the reasons for its brief dominance of the radio market after the turn of the century. Starting with the discovery of solid-state rectification and then through the development of the crystal detector the reader learns about great inventors such as Pickard, Braun, Dunwoody, and others. Radio fundamentals such as antennas, ground, lightning protection, tuned circuits, and detection are covered for the beginner. The unending compromise between selectivity and sensitivity is discussed for the crystal set designer. Advanced topics such as the use of multi-tuned circuits and wave traps follow for the more experienced experimenter.The crystal set embodies many of the basic concepts upon which modern radio electronics is based. By grasping these basics in their rarest form, the crystal set, the reader can build a powerful foundation for additional learning.

Download or read book Foxhole Radio written by Brian Carusella and published by Canyon Wren Press. This book was released on 2019-08-07 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foxhole Radio is the story of one of the more remarkable pieces of WWII soldier improvisation, a simple crystal radio receiver that used a razor blade for its detector. It is not remarkable for its technology - other radios worked better - but because hidden in its unglamorous amalgamation of scrounged parts is the history of army radio, morale, solid state electronics, field fortifications, and even military grooming. To distract himself for a while from the monotony of sitting in a foxhole and from the sporadic shelling by the enemy, a soldier on the Anzio beachhead made the first foxhole radio to listen to whatever stations might be in range. With no crystal nor cat whisker, he substituted what was on hand, a razor blade and a safety pin.It spread, by word of mouth mostly, across the beachhead, Europe and to the Pacific. Adopted by civilian radio enthusiasts, it became part of the lore of home experimenters and grade school science projects. More than a curious artifact of wartime improvisation, the foxhole radio reveals the story of the military's role in the radio development, and an intertwined tale of army shaving, corporate intrigue, and the evolution of the radio wave detector that led to the first solid state electronics. Foxhole Radio follows the history of army radio from the first experiments in the 1890s, to its coming of age during WWI, and its use for propaganda and morale during WWII. The razor and safety pin detector reveal a conflation of standard, archaic and folk radio wave detectors, the persistence of lore, and the army's battle with facial hair. The name "foxhole radio" itself tells of early field fortifications, words borrowed from across the lines, and the evolution of military jargon. Most importantly, Foxhole Radio tells the stories of the veterans who built these sets, how they built them, what they listened to, and their everyday realities. Though separated by thousands of miles with very different experiences, they were all united by a strange little radio and their desire to hear music and news from home.

Available in PDF, EPUB and Kindle. Book excerpt: Before delving into the mysteries of receiving and sending messages without wires, a word as to the history of the art and its present day applications may be of service. While popular interest in the subject has gone forward by leaps and bounds within the last two or three years, it has been a matter of scientific experiment for more than a quarter of a century. The wireless telegraph was invented by William Marconi, at Bologna, Italy, in 1896, and in his first experiments he sent dot and dash signals to a distance of 200 or 300 feet. The wireless telephone was invented by the author of this book at Narberth, Penn., in 1899, and in his first experiments the human voice was transmitted to a distance of three blocks. The first vital experiments that led up to the invention of the wireless telegraph were made by Heinrich Hertz, of Germany, in 1888 when he showed that the spark of an induction coil set up electric oscillations in an open circuit, and that the energy of these waves was, in turn, sent out in the form of electric waves. He also showed how they could be received at a distance by means of a ring detector, which he called a resonator.
