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. CUL. (That’s Morse Code for “see you later.”)

Within a few short years, fiber optics has skyrocketed from an interesting laboratory experiment to a billion-dollar industry. But with such meteoric growth and recent, exciting advances, even references published less than five years ago are already out of date. The Fiber Optics Illustrated Dictionary fills a gap in the literature by providing instructors, hobbyists, and top-level engineers with an accessible, current reference. From the author of the best-selling Telecommunications Illustrated Dictionary, this comprehensive reference includes fundamental physics, basic technical information for fiber splicing, installation, maintenance, and repair, and follow-up information for communications and other professionals using fiber optic components. Well-balanced, well-researched, and extensively cross-referenced, it also includes hundreds of photographs, charts, and diagrams that clarify the more complex ideas and put simpler ideas into their applications context. Fiber optics is a vibrant field, not just in terms of its growth and increasing sophistication, but also in terms of the people, places, and details that make up this challenging and rewarding industry. In addition to furnishing an authoritative, up-to-date resource for relevant industry definitions, this dictionary introduces many exciting recent applications as well as hinting at emerging future technologies.
