🔍 Key Concepts

• SELCAL (selective calling) use in ARQ (Automatic Repeat reQuest) radioteletype/telex systems • The typical format and length of a SELCAL code used in maritime telex/ARQ services • Difference between a numeric SELCAL code, a plain-language call sign/text, and a binary data pattern

💭 Think About

• Look at each option and ask: which one looks like an actual selective calling code that a coast station could assign, rather than a description or a data pattern? • Consider what an operator would practically enter or recognize on a maritime telex/ARQ terminal when calling a specific ship. • Decide which choices are descriptions or explanations about how the system works, versus an actual example of a SELCAL in the correct format.

✅ Before You Answer

• Check which option is a simple, specific code that could realistically be printed in a list of ship telex SELCALs. • Eliminate any choices that are not in a realistic SELCAL format (too long, includes words, or just describes binary). • Verify that the remaining option is something you could directly dial or key in as a selective calling code in ARQ communications.
