Which frequency is designated as the MF radiotelephony calling and Distress frequency?

• A. 2182 kHz
• B. 2172 kHz
• C. 2200 kHz
• D. 2222 kHz

Answer: (A)

In the MF radiotelephony band, there’s a single channel designated for both calling and distress to ensure quick and clear contact worldwide. That channel is 2182 kHz. It’s monitored by ships and coast stations everywhere, so it’s the default place to initiate a call or to send a voice distress message. When you need to call another station, you identify your vessel and the recipient’s call sign on this frequency. In a distress situation, you begin with Mayday and provide essential details, continuing on that same channel until assistance or contact is established. The other frequencies listed aren’t the standard MF calling or distress channel, so they wouldn’t serve the same universal purpose.
