Vhf Radio Frequency A Boater's Guide to Vhfand Gmdss by Sue Fletcher, 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.
VHF Marine Radio Handbook by Mike Whitehead, Mike Whitehead has written this informative book to help all boaters better understand and use their VHF Marine Radios. Not only does this book give you the correct procedures for any type of radio use but it also supplies valuable information not found in other books. This includes, NOAA Broadcast stations for over 300 areas of the county, Marine Radio Telephone Operator stations nationwide, FCC contact information, along with the rules and regulations that STILL govern the use of all VHF Marine Radios. If you own a boat with a VHF you need this book. If you own a boat without a VHF, get a radio and this book today - before you need both in an emergency.
VHF radio - VHF radio refers to several communications services in the VHF frequency range, including: Marine VHF radio - Marine VHF radio is installed on all large ships and most motorized small craft. It is mainly used for collision avoidance, summoning rescue services and communicating with harbours and marinas, and operates in the VHF frequency range, between 156 to 174 MHz. Basic exchange telecommunications radio service - In telecommunication, a basic exchange telecommunications radio service (BETRS) is a commercial service that can extend telephone service to rural areas by replacing the local loop with radio communications. In the BETRS, non-government ultra high frequency (UHF) and very high frequency (VHF) common carrier and the private radio service frequencies are shared. Very high frequency - Very high frequency (VHF) is the radio frequency range from 30 MHz (wavelength 10 m) to 300 MHz (wavelength 1 m). Frequencies immediately below VHF is HF, and the next higher frequencies are known as Ultra high frequency (UHF). vhfradiofrequency |
