Urgency Message Shape

On the nominated working frequency, the urgency call begins PAN-PAN three times, followed by the called station or ALL STATIONS three times, THIS IS, vessel name three times, call sign or other identification and MMSI if the announcement used DSC. The urgency message follows with position, situation, assistance or advice required, intentions and other useful response facts.

Position and response need are not decoration. A vague report such as 'engine trouble somewhere near the island' forces the receiving station to reconstruct the basics. Give the best verified position available and state uncertainty honestly.

Use OVER when a reply is required, release push to talk and listen. Read back critical instructions, write down medical or operational advice and update material changes. Never use voice on Channel 70; it carries DSC digital signalling only.
