The new Global Maritime Distress and Safety System (GMDSS) is revolutionizing emergency communications and international search and rescue at sea. In recognition of this leap forward, all new marine radios are now equipped with digital selective calling (DSC). The Boatowner's Guide to GMDSS and Marine Radio explains clearly and concisely how this revolutionary maritime 911 equipment works and describes the enormous advantages of digital VHF radio for ordinary communications with fellow boaters. The book comes with an interactive CD-ROM that shows you how to send emergency messages on a Class-D DSC equipped VHF radio, how to communicate with ships you want to avoid or whose assistance you need, how to call specific boats using digital selective calling, and how to set your digital receiver to "ring" so you will be alerted to incoming calls.
