🔍 Key Concepts

• Sea area A1 definition under GMDSS (Global Maritime Distress and Safety System) • Which frequencies/channels are used for DSC (Digital Selective Calling) vs. traditional aural (voice) watch • Specific purpose of VHF channels 16 and 70 and how GMDSS changed watchkeeping requirements

💭 Think About

• Ask yourself: In sea area A1, what type of coast station coverage is guaranteed, and on what band (VHF/MF/HF)? • Which VHF channel is reserved for DSC-only use, and which is used for voice distress, safety, and calling? • How did GMDSS change the old requirement for listening on 2182 kHz and VHF channel 16?

✅ Before You Answer

• Verify the definition of sea area A1 (hint: it specifically mentions continuous DSC watch by coast stations on a certain VHF channel). • Check which channel/frequency is designated exclusively for DSC in the VHF band (not used for routine voice). • Confirm that 2182 kHz and 8514.5 kHz relate to MF/HF distress arrangements and whether they apply as a mandatory continuous watch in sea area A1.
