Download or read book Ham Radio For Dummies written by H. Ward Silver and published by John Wiley & Sons. This book was released on 2011-02-25 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: It’s time we cleared the air about ham radio. If you think of it as staticky transmissions sent by people in the middle of nowhere, think again. Today’s ham radio goes beyond wireless to extreme wireless, Operators transmit data and pictures, use the Internet, laser, and microwave transmitters, and travel to places high and low to make contact. In an emergency or natural disaster, ham radio can replace downed traditional communication and save lives. Whether you’re just getting turned on to ham radio or already have your license, Ham Radio for Dummies helps you with the terminology, the technology and the talknology. You discover how to: Decipher the jargon and speak the language Buy or upgrade your equipment, including the all-important antennas Build a ham radio shack, complete with the rig, a computer, mobile/base rig, microphones, keys, headphones, antennas, cables and feedlines Study for your license, master Morse code, take the test and get your call sign Understand the basics of ragchews (conversations), nets (organized on-air meetings) and DX-ing (competing in contacts to make contacts) Keeping logs with the vital statistics, including time (in UTC or World Time), frequency, and call sign Written by Ward Silver, an electrical engineer, Certified Amateur Radio License Examiner, and columnist for QST, a monthly magazine for ham operators, Ham Radio for Dummies gives you the info you need to delve into the science or dive into the conversation. It explains how you can: Tune in to the most common types of signals, including Morse Code (CW), single-sideband (SSB), FM, Radioteletype (RTTY), and data signals Break in, introduce yourself, converse, and say or signal goodbye Communicate while traveling (ham radio goes where mobile phones go dead) Register with an emergency organization such as ARES and RACES Help in emergencies such as earthquakes, wildfires, or severe weather Pursue your special interests, including contacting distant stations, participating in contests, exploring the digital modes, using satellites, transmitting images, and more Complete with a glossary and ten pages of additional suggested resources, Ham Radio for Dummies encourages you to touch that dial and take that mike.

Download or read book Super Multi Band Antennas written by Edward J. Shortridge and published by Dog Ear Publishing. This book was released on 2017-03-29 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two previous books titled “Super-Dipole” and “Super Max-Dipole” Antennas were written by this author, thereby introducing a completely new “Unified Broad-Banding Method”. This method primarily consists of the use of a 1/2 wavelength Dipole, which is fed with a 1/4 (or shorter) wavelength resonant line. The amount of coupling between these two components is greatly reduced and controlled to produce a wide SWR bandwidth. This Broad-Banding method is referred to as “Critically-Coupled Broad-Banding”. This new book, titled “Super Multi-Band Antennas” is a continuation of the previous book, where Broad-Banding is taken to an extreme and Dual-Band antennas can be configured either on an adjacent band or those that might have a much greater 2 to 1 frequency separation. Early chapters of this book reintroduce the “Unified Broad-Banding Method”, presenting Horizontal antennas with superb SWR bandwidths and then showing Dual-Band versions with many different band combinations from 60m on up to 450 MHz, using either wire or tubing. Single band Folded-Dipole configurations using tubing or Ladder-line/Window-line are shown to produce extremely low SWR bandwidths. Inverted “V” Dual-Band antennas, with many band combinations allow for easier antenna mounting. Both Vertical and Horizontal Single-fed, Dual-Band Quad antennas have a limited bandwidth but when each individual 1/2wL section is fed, these antennas are classified as a “Prismatic Polygon” and thereby achieve far greater bandwidth, achieving it in a totally different manner from the “Critically-Coupled” method. There are many versions of Quad, Triangular, Pentagons and Hexagon Polygon antennas and all of their Multi-radiators must be fed. Some can cover from 30 to 10m, while others can cover from 144 to 450 MHz, allowing all services within the bandwidth, including the Amateur Radio services to use these antennas. This book presents large numbers and a variety of antennas and it also provides a path of the evolution from one type of antenna to another, providing detailed performance. Many thanks again to Eugene Belton and Dale Parfitt for their dedicated hard work, which without; these books would not have been possible. Surely you will be pleased with the extent of information provided, which covers important details.
Download or read book Millimeter Wave Low Noise Amplifiers written by Mladen Božanić and published by Springer. This book was released on 2017-11-30 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first standalone book that combines research into low-noise amplifiers (LNAs) with research into millimeter-wave circuits. In compiling this book, the authors have set two research objectives. The first is to bring together the research context behind millimeter-wave circuit operation and the theory of low-noise amplification. The second is to present new research in this multi-disciplinary field by dividing the common LNA configurations and typical specifications into subsystems, which are then optimized separately to suggest improvements in the current state-of-the-art designs. To achieve the second research objective, the state-of-the-art LNA configurations are discussed and the weaknesses of state-of the art configurations are considered, thus identifying research gaps. Such research gaps, among others, point towards optimization – at a systems and microelectronics level. Optimization topics include the influence of short wavelength, layout and crosstalk on LNA performance. Advanced fabrication technologies used to decrease the parasitics of passive and active devices are also explored, together with packaging technologies such as silicon-on-chip and silicon-on-package, which are proposed as alternatives to traditional IC implementation. This research outcome builds through innovation. Innovative ideas for LNA construction are explored, and alternative design methodologies are deployed, including LNA/antenna co-design or utilization of the electronic design automation in the research flow. The book also offers the authors’ proposal for streamlined automated LNA design flow, which focuses on LNA as a collection of highly optimized subsystems.

Read on your PC, Mac, smart phone, or tablet device. Operating a ham radio is fun and most people's interest in amateur radios are driven by the fun aspect of it. Asides the excitement, Amateur radio could be very helpful in emergency situations especially when other services are unavailable. A typical example of an emergency case is the 1992 Hurricane Andrew that hit South Florida. It destroyed the common means of communication, its antennas, utility grid, and its cellular networks were all destroyed leaving victims almost helpless. At that time, amateur radio was the only source of communication and some payphones that were connected with underground lines. They are also used for many other community services Radio Amateurs around the world provide a valuable community service. This book will teach you how to operate one, learn about tuning to the right frequency, when to tune and making consistent contacts and much, much more. Here Is A Preview Of What You'll Read...
