Available in PDF, EPUB and Kindle. Book excerpt: Your how-to guide to become a ham Ham radio, or amateur radio, is a way to talk with people around the world in real-time, or to send email without any sort of internet connection. It provides a way to keep in touch with friends and family, whether they are across town or across the country. It is also a very important emergency communication system. When cell phones, landlines, the internet, and other systems are down or overloaded, Amateur Radio still gets the message through. Radio amateurs, often called "hams," enjoy radio technology as a hobby, but are often called upon to provide vital service when regular communications systems fail. Ham Radio For Dummies is your guide to everything there is to know about ham radio. Plus, this updated edition provides new and additional information on digital mode operating, as well as use of amateur radio in student science and new operating events. • Set up your radio station • Design your ham shack • Provide support in emergencies and communicate with other hams • Study for the licensing exam and choose your call sign If you're looking to join a college radio club or just want to learn the latest tips and tricks, this book is a helpful reference guide to beginners, or those who have been "hams" for years.

Download or read book Practical Antenna Handbook 5 e written by Joseph Carr and published by McGraw Hill Professional. This book was released on 2011-10-25 with total page 785 pages. Available in PDF, EPUB and Kindle. Book excerpt: THE DEFINITIVE ANTENNA REFERENCE--FULLY REVISED AND EXPANDED! Design and build your own antennas with the help of this unique guide. 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

This read ranks right up there with so many of the ARRL (American Radio Relay League) books and publications. If you enjoyed reading 200 Meters & Down, or The World of Ham Radio, 1901-1950, you will be fascinated with this text. Gary writes as if he is having a conversation with you over a cup of coffee while he explains many lesser-understood topics in such a manner that anyone can understand them. He shares what he has learned in recent years, and explains how ham radio has evolved and lived on amidst smartphones, PCs, and the Internet. The hobby is not dying but instead thriving and actually GROWING! Gary talks about "traditional" ham radio; the stuff hams did and continue to do using HF radios, antenna tuners, wire and/or beam antennas, working DX, QSLing, and contesting. It is about what he remembers from the past, and what is currently happening in the field of ham radio today. You will find bits and pieces of history as well as a little humor blended among many of the various subjects. This transcript is a must read for any inactive radio amateur and the licensee who wants to learn a little bit more than he already knows about this magnificent hobby. As Tim Duffy, K3LR, COO of DX Engineering, wrote in his forward of the book, "Whether you are a long time Ham Radio enthusiast or just getting started, you will find this book hard to put down."
Download or read book Indonesia s Secret War written by Robin Osborne and published by Allen & Unwin Academic. This book was released on 1985 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the historical development of the Irian Jaya guerrilla struggle for independence from Indonesia. The OPM, Organisasi Papua Merdeka, has been fighting Indonesian rule in West New Guinea since 1969; the military presence there was established in 1962. The author believes that the great majority of West Papuans support the OPM. The Indonesian Transmigration programme has forcible alienated clan land and sponsored settlers from Java. As a result of this policy 10,000 Papuans fled Irian Jaya in mid-1984 to seek safety in Papua New Guinea. The exodus was more than 1 per cent of the indigenous population. The OPM has almost no foreign allies. Both Papua New Guinea and Australia emphasize that Irian Jaya is part of Indonesia and thus an internal matter. The author predicts that greater autonomy for Irian Jaya would be more likely to result from political pressure on Jakarta than from a military victory by OPM.
