| What is DSC ? Digital Selective Calling is a component of the international distress and safety system the time, precise location and unique ID of the vessel (MMSI) in trouble is broadcast when the DISTRESS button is pressed. When GMDSS is fully implemented, Channel 16 will be replaced by Channel 70 which is already permanently monitored by rescuing forces, for optimum safety. With DSC, the boater can also send and receive messages digitally. You can efficiently transmit and receive communications, from/to a selected vessel, between a group of vessels or ship-to-shore. To do this, each user is assigned a unique MMSI number which becomes the boat's identification. |
