Foxhole Radio by Brian Carusella Pdf

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.

Rick Brant's Science Projects by John Blaine Pdf

A non-fiction companion volume to the popular Rick Brant Science-Adventure Series. This reprint of a very hard-to-find title includes easy-to-read chapters about codes and ciphers, slingshots and archery, microscopes and radios, tricks and games, and scientific experiments and how to plan a science project. Please Note: These experiments have not been written with the modern reader in mind. Some may be dangerous and should not be undertaken. The Rick Brant series was written pseudonymously under the name John Blaine from 1946-1968 . Many millions of the books were sold. Rick Brant was a high school boy who lived on an island off the coast of New Jersey. His father was a world-famous scientist. Rick's best friend was Donald "Scotty" Scott and together they have adventures all over the globe usually involving a secret science project of some kind. Originally published in 1960.

Microwave Circuit Design Using Linear and Nonlinear Techniques by George D. Vendelin,Anthony M. Pavio,Ulrich L. Rohde Pdf

The ultimate handbook on microwave circuit design with CAD. Full of tips and insights from seasoned industry veterans, Microwave Circuit Design offers practical, proven advice on improving the design quality of microwave passive and active circuits-while cutting costs and time. Covering all levels of microwave circuit design from the elementary to the very advanced, the book systematically presents computer-aided methods for linear and nonlinear designs used in the design and manufacture of microwave amplifiers, oscillators, and mixers. Using the newest CAD tools, the book shows how to design transistor and diode circuits, and also details CAD's usefulness in microwave integrated circuit (MIC) and monolithic microwave integrated circuit (MMIC) technology. Applications of nonlinear SPICE programs, now available for microwave CAD, are described. State-of-the-art coverage includes microwave transistors (HEMTs, MODFETs, MESFETs, HBTs, and more), high-power amplifier design, oscillator design including feedback topologies, phase noise and examples, and more. The techniques presented are illustrated with several MMIC designs, including a wideband amplifier, a low-noise amplifier, and an MMIC mixer. This unique, one-stop handbook also features a major case study of an actual anticollision radar transceiver, which is compared in detail against CAD predictions; examples of actual circuit designs with photographs of completed circuits; and tables of design formulae.

Software Defined Radio by Fouad Sabry Pdf

What Is Software Defined Radio A radio communication system known as software-defined radio (SDR) is one in which components that are typically implemented in hardware are, instead, implemented by means of software on a personal computer or embedded device. Historically, radio components have been implemented in hardware. Although software-defined radio is not a new idea, the constantly advancing capabilities of digital electronics have made it feasible to practically implement many procedures that were previously only conceivable in theory. How You Will Benefit (I) Insights, and validations about the following topics: Chapter 1: Software-defined radio Chapter 2: Amplitude modulation Chapter 3: Modulation Chapter 4: Orthogonal frequency-division multiplexing Chapter 5: Baseband Chapter 6: Frequency-shift keying Chapter 7: Index of electronics articles Chapter 8: Electromagnetic interference Chapter 9: Mixed-signal integrated circuit Chapter 10: Universal Software Radio Peripheral Chapter 11: S meter Chapter 12: Analogue electronics Chapter 13: Direct-conversion receiver Chapter 14: Radio receiver design Chapter 15: Digital down converter Chapter 16: OpenHPSDR Chapter 17: Unified S-band Chapter 18: List of software-defined radios Chapter 19: Red Pitaya (hardware) Chapter 20: RF CMOS Chapter 21: List of amateur radio transceivers (II) Answering the public top questions about software defined radio. (III) Real world examples for the usage of software defined radio in many fields. (IV) 17 appendices to explain, briefly, 266 emerging technologies in each industry to have 360-degree full understanding of software defined radio' technologies. Who This Book Is For Professionals, undergraduate and graduate students, enthusiasts, hobbyists, and those who want to go beyond basic knowledge or information for any kind of software defined radio.
