Which frequency is designated for On-scene Distress and Safety communications?

The frequency designated for On-scene Distress and Safety communications is 2174.5 kHz. This frequency is specifically allocated for maritime distress and safety communications, allowing vessels and rescue coordination centers to communicate effectively in emergency situations. It operates in the medium frequency band and is uniquely identified for its role in facilitating direct communications during incidents at sea, where immediate and clear communication can be crucial for the safety of life at sea.

Other frequencies mentioned do have specific uses, but they are not designated for On-scene Distress and Safety communications. For instance, 4209.5 kHz and 518.0 kHz are used for different aspects of maritime communication, such as weather broadcasts and maritime safety information, while 490.0 kHz is primarily reserved for the GMDSS’s Digital Selective Calling (DSC) operations. Each frequency serves a specific role, thereby ensuring that communication channels are efficient and tailored to the various needs of maritime safety and navigation.
