🔍 Key Concepts

• SITOR/NBDP modes – difference between ARQ (two-way) and FEC/BFEC (one-way broadcast) • Typical uses of BFEC (Broadcast Forward Error Correction) in GMDSS for safety information and weather • What services use NAVTEX versus HF NBDP (frequency bands and purpose)

💭 Think About

• Ask yourself: Is BFEC mainly for one-way broadcast information, two‑way messaging, or both? • Which of the listed options involves functions that clearly require a return channel (acknowledgment) versus pure broadcast reception? • Which systems normally carry Maritime Safety Information (MSI), and on what bands (MF/HF NAVTEX vs HF NBDP vs VHF)?

✅ Before You Answer

• Identify which answer choices include two‑way sending/receiving and which are receive‑only broadcast functions – that matters for BFEC. • Check which items in the choices are normally provided on HF NBDP (e.g., HF MSI, weather, traffic lists) versus those usually associated with VHF voice or NAVTEX (518/490 kHz). • Verify which mode (ARQ vs FEC/BFEC) is typically used for distress TELEX versus routine/weather/traffic-list broadcasts.
