■ Urgency -DSC communications on MF, HF and VHF

      ▶ Transmission of DSC Urgency Alert (Manoverboard/Medical and other urgent cases)

     

      Transmission of urgency messages shall be carried out in two steps.

• announcement of the urgency message
• transmission of the urgency message

      The announcement is carried out by transmission of a DSC urgency call on the DSC distress

      calling channel (4,6,8,12,16mHz on HF, 2187.5kHz on MF, Channel 70 on VHF)

      The urgency message is transmitted on the distress traffic channel(RTF 4,6,8,12,16mHz on HF

      2182.0kHz on MF, Channel 16 on VHF)

      The DSC urgency call may be addressed to all stations at VHF, or a geographic area at MF/HF,

      or to a specific station. The frequency on which the urgency message will be transmitted shall be 

      included in the DSC urgency call

      The transmission of an urgency message is thus carried out as follows;

• tune the transmitter to the DSC distress calling channel(on HF/MF/VHF according to the range from shore)
• select the appropriate calling format on the DSC equipment(all ships(VHF only), geographic area(MF/HF only) or individual);
• transmit DSC urgency alert(call)
• transmit the urgent message as follows;

          - "PAN PAN", repeated 3times

          - "ALL STATIONS" or called station, repeated 3times

          - "this is"

          - the 9-digit identity and the call sign or other identification of own ship

          - the text of the urgency message

 eg.:

         =OCEAN PIONEER=
