Which of the following is NOT a use of a DSC radio?

A Digital Selective Calling (DSC) radio is primarily designed for maritime communication, particularly for safety and distress situations. One of its key features is the ability to send automated distress alerts and establish contact between vessels and shore stations, which serves to enhance safety and facilitate communication in emergencies.

The process of identifying the location of weather buoys does not fall under the typical uses of a DSC radio. Weather buoys typically relay weather data via other systems, such as satellite or buoyancy-based signals, rather than utilizing the DSC's communication capabilities. Thus, while a DSC radio is invaluable for direct communication or distress signaling, recognizing the location of weather buoys is outside its intended scope of operation.
