The Oricom MX1000W is a high performance Marine VHF radio, and an essential part of your safety kit when on the water. Rated to IP67 and including class D Digital Selective Calling (DSC), this radio ensures that in an emergency, you are only ever a distress call away from safety. What is DSC? The Digital Selective Calling (DSC) feature on your MX1000 Marine VHF radio uses an arranged digital data message, instead of voice, in order to transmit urgent or important information to another radio. DSC is designed to alert all radios within a predetermined range to a distress message, even if the vessel’s listening watch is not being maintained, as this increases the chance of the signal being heard.
