DSC (Digital Selective Calling)

Digital Selective Calling (DSC) is a communication system used in maritime radio to securely and efficiently send distress signals and routine messages. It allows vessels to quickly contact specific ships or coast stations by selecting a unique identification code, similar to dialing a phone number. When a distress situation arises, DSC automatically sends a coded alert to designated entities, ensuring rapid response. This system enhances safety at sea by streamlining communication, reducing misunderstandings, and enabling precise targeting of messages in emergencies or regular operations.
