Download or read book Unidentified written by Robert Salas and published by Career Press. This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1969 the U.S. Air Force issued a statement that read' "No UFO reported, investigated and evaluated by the Air Force was ever an indication of threat to our national security." This statement is patently false. It has been proven untrue by the testimony of many military officers and airmen and documentation of incidents involving UFOs and nuclear weapons, testimonies of which the U.S. Air Force was fully aware. Unidentified details many of these testimonies, some for the first time. As partial justification for its position, the Air Force cites a University of Colorado study that was contracted and paid for by federal funds. Unidentified reveals how this study was actually just another part of the plan to cover up the reality of the UFO phenomenon. For the first time, Unidentified publishes evidence that the investigators for the Colorado study knew about the UFO-related missile shutdown incidents but did not investigate them or include them in their final report.

Download or read book The Electronics of Radio written by David Rutledge and published by Cambridge University Press. This book was released on 1999-08-13 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fascinating book provides a stimulating introduction to analog electronics by analysing the design and construction of a radio transceiver. Essential theoretical background is given along with carefully designed laboratory and homework exercises. The author begins with a thorough description of basic electronic components and simple circuits and goes on to describe the key elements of radio electronics, including filters, amplifiers, oscillators, mixers, and antennas. Laboratory exercises lead the reader through the design, construction, and testing of a popular radio transceiver (the NorCal 40A). A diskette containing the widely known circuit simulation software, Puff, is included in the book. This was the first book to deal with elementary electronics in the context of radio. It can be used as a textbook for introductory analog electronics courses, for more advanced undergraduate classes on radio-frequency electronics, and will also be of great interest to electronics hobbyists and radio enthusiasts.

Download or read book Encounter with Tiber written by Buzz Aldrin and published by Open Road Media. This book was released on 2013-05-28 with total page 802 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Apollo 11 astronaut and the Nebula Award–nominated author of Directive 51 present a novel that “conveys the wonder and promise of space” (Publishers Weekly). Born the year of the Moon landing, Chris Terence spends his life fighting to return humanity to that pinnacle. An engineering student with dreams of spaceflight, he finds upon graduation that the United States no longer has need for astronauts. Years of bureaucratic meddling have reduced the space program to a shell of itself, and it will take the greatest scientific find in history to send humanity skyward once more. After years battling budget hawks, Chris finally gets his chance to walk on the Moon. While there, he finds evidence of an ancient alien civilization, the Tiberians, who visited Earth’s satellite eight thousand years before. Understanding what happened to those long-forgotten travelers will define the lives of Chris and his son, as they fight against all odds to unlock the secrets of the universe. “The collaboration of the first man to pilot a moon lander (Aldrin) with a major voice in contemporary science fiction (Barnes) has produced a fascinating chronicle of man’s first encounter with alien intelligence” (Booklist).

Updated and revised to provide clear answers to questions frequently asked by hobbyists and electronics technicians, Practical Antenna Handbook, Fifth Edition blends theoretical concepts with hands-on experience--requiring only high school mathematics Reorganized to flow logically from broad physical principles to specific antenna design and construction techniques, the book begins by covering the fundamentals. Then the half-wave dipole is discussed both as an excellent antenna in its own right and as a conceptual tool for predicting the performance of other designs. Transmission line impedance matching techniques--and a companion Smith chart tutorial--lead into "must have" accessories for tuning, monitoring, and troubleshooting antenna system performance. Other tools, such as antenna modeling software and network analyzer add-ons for PCs and Macs, are addressed, and concluding chapters offer fresh insights into support structures and installation techniques. NEW TOPICS COVERED INCLUDE: Characteristics of all-driven and parasitic arrays Beverages and small MF/HF receiving loops Top-loaded shunt-fed towers and other verticals Theory and design of Yagi beams Effect of real ground on propagation and antenna patterns, impedance, and efficiency Lightning protection and four kinds of ground systems Zoning and restrictive covenants COVERS A WIDE VARIETY OF ANTENNAS: Dipoles and inverted-Vs Quads, delta, and NVIS loops Wire arrays (bobtail curtain, half-square, rhombic) Verticals and shunt-fed towers Rotatable Yagi beams MF/HF receiving antennas (flag, pennant, K9AY, Beverage) Mobile and portable antennas VHF/UHF/microwave antennas And many more GO TO WWW.MHPROFESSIONAL.COM/CARR5 FOR: * Tables of worldwide geographic coordinates and antenna dimensions vs. frequency * Supplier updates * Author's blog * Additional photographs and schematics * Links to tutorials and specialized calculators
