Which modes could be selected to receive vessel traffic lists from high seas shore stations?

🔍 Key Concepts

• GMDSS (Global Maritime Distress and Safety System) broadcast methods for safety information • Difference between modulation types (AM, FM, SSB) and digital data modes (ARQ, FEC) • Which modes are used for NAVTEX and HF MSI (Maritime Safety Information) like weather and traffic lists

💭 Think About

• Ask yourself: Are vessel traffic lists from high seas shore stations normally sent as voice communications, or as printed/decoded text data? • Which of these options are operating modes/protocols for digital telex-style messages, and which are just radio bands or modulation types? • For HF (high frequency) MSI broadcasts, which specific telex modes are used so that ships can receive messages automatically without operator listening all the time?

✅ Before You Answer

• Identify which options contain actual telex data modes (not just radio bands or modulation types). • Recall that HF high seas coast stations sending safety and traffic lists use NBDP/RTTY-style transmissions—what two modes are commonly paired there? • Eliminate any choices that rely only on voice reception without an automatic printed or stored message capability.
