What is the frequency 2182 kHz primarily used for?

The frequency 2182 kHz is primarily designated for international distress voice communication. This frequency is recognized globally for emergency situations at sea, allowing vessels to communicate distress calls to nearby ships and shore stations. It serves as a vital lifeline for mariners, enabling them to send distress alerts, seek assistance, and provide critical information during emergencies.

The significance of this frequency is underscored by regulations established by the International Maritime Organization (IMO), which mandates its use for emergency communications. This emphasizes the importance of having a designated frequency for distress situations to ensure that help can be rapidly coordinated.

While the other options suggest various forms of maritime communication such as ship-to-ship and routine navigation, they do not capture the specific and critical function of 2182 kHz as a dedicated channel for emergency and distress traffic. Thus, understanding this distinction is crucial for maritime operators and information systems technicians alike.
