🔍 Key Concepts

• SELCAL (Selective Calling) format and purpose in maritime radio • Difference between ship station and coast station call numbers • Typical length (number of digits) and structure of a ship station SELCAL

💭 Think About

• Look at the number of digits in each option and recall how long a ship station SELCAL usually is. • Think about which of these look more like an MMSI (Maritime Mobile Service Identity) and which look like a short selective call code. • Ask yourself: for routine ship‑to‑ship or ship‑to‑coast selective calling on HF/MF, what kind of simple numeric code was historically assigned to ship stations?

✅ Before You Answer

• Verify the standard digit length of a ship station SELCAL in the relevant ITU/Radio regs or training material. • Eliminate any option that looks like an MMSI (9 digits) rather than a SELCAL. • Confirm that ship station SELCALs are typically shorter codes, not long identification numbers.
