The first complete, hands-on VHF guide for recreational boaters The Global Maritime Distress and Safety System (GMDSS) represents a complete overhaul of marine communications, which hadn't changed much since the Morse code system was instituted after the "Titanic sank in 1912. VHF analog radio has long been essential for two-way communcation between boats or between a boat and a shore station within line-of-sight distance of one another. But GMDSS uses VHF radios fitted with digital selective calling (DSC), which allows automated radio calls. A VHF-DSC radio can selectively call another digital radio by call number, just as a telephone does, and in the case of distress, urgency, and safety calls, all vessels and coast stations within receiving distance are alerted; once programmed, the DSC radio will broadcast and repeat your digital ID, your position, and a Mayday message to rescue personnel. Endorsed by the U.S. Coast Guard and written by a VHF-DSC radio trainer, "A Boater's Guide to VHF and GMDSS is a user-friendly guide that gets recreational boaters quickly up to speed on using both analog and digital VHF radiotelephones. Think of it as your on-call radio resource, with step-by-step instructions, illustrations of what the radio displays will look like, and sample transmissions. Sue Fletcher's straightforward explanations are accompanied by highlighted tips, guides to radio "Geek-Speak," and a Quick Reference chart, so you'll easily master what you need to know aboutSelecting and setting up a DSC or analog VHF system VHF radio protocol, including radio regulations, transmission etiquette, and channel allocation Using and getting the most out of your radio, including calls,weather, and port operations A full explanation of GMDSS, including equipment requirements, EPIRBs, SARTs, and Navtex "The U.S.

The definitive engineer's guide to designing and building software-based radios.The first systematic guide to software radio design and implementationMultirate DSP, RF front-ends, direct digital synthesis of modulated waveforms, A/D and D/A conversion, and moreEnhancing performance through smart antennas and other adaptive array algorithmsTechniques for building more flexible, extensible software Radios, once implemented purely in hardware, are increasingly built using programmable digital signal processing (DSP) devices that enhance device flexibility, simplify manufacture, and reduce costs. However, many engineers are unfamiliar with the latest techniques for building software radios for wireless systems and devices. This book fills the gap, introduces the key concepts of software radio design, and covers every issue and technique engineers must understand to successfully utilize DSP in their radio systems and subsystems. Coverage includes: Central role of multirate DSP in software radio design Constructing RF front-ends: utilizing digital processing to overcome key problems in RF designDirect digital synthesis of modulated waveformsA/D and D/A converters and conversion processes: key tradeoffs among resolution, sample rate, and dynamic rangeEnhancing performance through smart antennas and other adaptive array algorithmsPractical techniques for choosing among DSP microprocessors, FPGAs, and ASICsA systematic, object-oriented approach to creating flexible software The book concludes with case studies drawn from the advanced work of the SDR Forum, the leading consortium of companies, universities, and research organizations promoting software radio development.

Digital radio - Digital radio describes radio technologies which carry information as a digital signal. See also software radio for a discussion of radios which use digital signal processing.

Digital television radio - Digital television radio (or DTR) is an informal term which describes the music channels that are provided with a digital television service. In terms of price and musical variety, DTR falls somewhere between regular AM or FM radio, and satellite radio.

Digital Audio Radio Satellite - Digital Audio Radio Satellite or DARS (also as SDARS, for Satellite Digital Audio Radio Service, among many variations) is the FCC term for satellite radio, currently being made popular in the U.S.

Digital Radio Mondiale - Digital Radio Mondiale (DRM) is an international non-profit consortium committed to designing and implementing an open-source platform for digital radio broadcasting around the world, especially on shortwave. Unlike most other DAB systems, DRM uses IBOC technology and can operate in a hybrid mode called Single Channel Simulcast, simulcasting both analog signal and digital signal.
