World's Best Hobby is an unusual title for a memoir, which is exactly what this book is. It's my life in the fascinating hobby of Amateur Radio. Much of my professional life is spent producing documentary and reality programs for television (including more than a few about Ham Radio) where I learned that the purpose of a title is to attract an audience and if it was also true, all the better. The challenge with documentary films is to make them entertaining first and foremost, and informational if possible. I've tried very hard to make this book entertaining, and from feedback I've gotten (from Hams and wannabee Hams who found it posted online as I was writing it) I've succeeded, at least to some extent. I tried to make the book fun because Ham Radio is fun. And Ham Radio has more facets than a cheap diamond, as you'll discover as you dig into World's Best Hobby. Enjoy! PS. Let me know what you think of World's Best Hobby - especially if you like it. 73, Dave Bell, W6AQ
Based on the popular Artech House classic, Digital Communication Systems Engineering with Software-Defined Radio, this book provides a practical approach to quickly learning the software-defined radio (SDR) concepts needed for work in the field. This up-to-date volume guides readers on how to quickly prototype wireless designs using SDR for real-world testing and experimentation. This book explores advanced wireless communication techniques such as OFDM, LTE, WLA, and hardware targeting. Readers will gain an understanding of the core concepts behind wireless hardware, such as the radio frequency front-end, analog-to-digital and digital-to-analog converters, as well as various processing technologies. Moreover, this volume includes chapters on timing estimation, matched filtering, frame synchronization message decoding, and source coding. The orthogonal frequency division multiplexing is explained and details about HDL code generation and deployment are provided. The book concludes with coverage of the WLAN toolbox with OFDM beacon reception and the LTE toolbox with downlink reception. Multiple case studies are provided throughout the book. Both MATLAB and Simulink source code are included to assist readers with their projects in the field.
Filled with tested, hands-on projects that really work, this great reference features single-sided circuit boards that are easy to build and includes detailed circuit-board layouts and extensive parts lists. (Technology)
A shortwave radio, without use of satellites, will receive commercial free foreign government supported English language radio programs from thousands of miles away! Shortwave radios can be built at home in a time period of a few hours to a few weeks. This book contains over one hundred illustrations. Written for both the expert and the novice, it provides information for understanding how the radios work, for obtaining the necessary parts, and for constructing the radios. Shortwave radios were first developed in the 1930s and new designs can be built to resemble radios of that era.

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
