🔍 Key Concepts

• NAVTEX purpose and how it fits into the GMDSS (Global Maritime Distress and Safety System) • The standard international frequency used for English‑language NAVTEX broadcasts • How MF (medium frequency) distress/safety frequencies differ from DSC distress calling and VHF calling channels

💭 Think About

• Ask yourself: Which option is specifically tied to NAVTEX worldwide, rather than general distress or calling? • Look at each frequency and recall: Is this used for DSC distress calling, voice safety traffic, or navigational and meteorological warnings (NAVTEX)? • Think about which GMDSS Sea Area concept is actually relevant to NAVTEX, and which options are mixing systems together.

✅ Before You Answer

• Identify which of the choices is designated as the international NAVTEX MF frequency for MSI (maritime safety information). • Eliminate any frequencies you know are used for DSC distress and safety calling rather than NAVTEX. • Check that the correct choice is not shared with routine voice or DSC calling, but is reserved for NAVTEX broadcasts.
