MF/HF Distress & Calling Frequencies

Voice - mode USB or J3E

The MF/HF distress & calling frequencies should be programmed into the first six channels of your marine MF/HF transceiver.

Select 8291 KHz before switching the radio off so that frequency is the default at power on.

2182 4125  6215 8291 12290 16420 


All ships ceased monitoring the above frequencies in 1999, and very few remaining maritime coast stations monitor them 24/7 today.

For the above reasons, and the complexity involved in operating the equipment during an emergency, a MF/HF transceiver WITHOUT DSC (digital selective calling) capability should NOT be relied upon in an emergency.
