HVG MARINE ELECTRIC EQUIPMENT 0081: Class-A VHF DSC Ship Transceiver
DSC (Digital Selective Calling) is a new feature brought to radio communications by the arrival of GMDSS (Global Maritime Distress Safety Systems). This feature is found on VHF and MF/HF GMDSS radio systems. A calling station may direct a call to a specific vessel by entering a MMSI (Maritime Mobile Service Identity) number and initiating a call. The receiving station decodes the number and if there is a match an alert is sounded indicating a communications request has been made. Other information may be embedded in the coded signal indicating nature of the call and operating frequency requested. If the coded signal is of a distress, it will sound an alarm on all receiving stations and indicate the position of the calling station. This allows for vessels in the area to respond and render aid.
