What is the MF radiotelephony calling and distress frequency?

The MF radiotelephony calling and distress frequency is recognized as 2182 kHz. This frequency is specifically designated for maritime distress communications and serves as an international standard for ship-to-ship and ship-to-shore communication in emergency situations. The sole purpose of this frequency is to facilitate urgent and lifesaving communications, ensuring that vessels in distress can reach nearby ships or coastal stations.

Using 2182 kHz for distress calls allows for a unified channel that all maritime operators are aware of, which increases the likelihood of receiving timely assistance. Additionally, this frequency is monitored by coast stations and is established under international regulations, making it critical for safety at sea.

While the other frequencies mentioned relate to different communication needs or are used in different contexts, they do not serve the specific role of a distress calling frequency in the MF band.
