What should a GMDSS Radio Operator do if a NAVTEX warning message is received but it contains too many errors to be usable?

🔍 Key Concepts

• NAVTEX message categories (A, B, D, etc.) and what they cover • How repeated and corrected NAVTEX broadcasts are normally handled • Role of NAVAREA coordinator and MSI (Maritime Safety Information)

💭 Think About

• Think about who is responsible for correcting and rebroadcasting faulty NAVTEX messages—individual ships or shore authorities? • Consider whether a GMDSS operator should passively wait, actively request specific categories, or switch to another source of information. • Ask yourself: in an urgent safety situation, what alternate source of Maritime Safety Information would most likely repeat the same warning for mariners in the area?

✅ Before You Answer

• Verify what Category A, B, D, and L NAVTEX messages are intended for and whether a ship normally ‘requests’ them individually. • Check standard GMDSS procedures: does a ship normally call the NAVAREA coordinator directly just because of a garbled broadcast? • Confirm which other GMDSS or national services routinely repeat navigational and weather warnings for your sea area.

Do nothing. Vital NAVTEX messages will be repeated on the next scheduled broadcast.

Contact the NAVAREA coordinator and request a repeat broadcast.

Initiate a request for Category A, B, L and D messages.

Listen to appropriate VHF weather channel for repeat warnings.
