🔍 Key Concepts

• International Code of Signals (INTERCO) procedures for visual/flash signals • Standard abbreviations used in Morse/flash communications for ‘say again’ or ‘repeat’ • Difference between procedural signal groups (prosigns) and plain language words like REPEAT

💭 Think About

• Which of these options looks like a standard procedural signal group rather than normal text or random letters? • In Morse/flash communications, what short group is commonly used on radio, flags, and flashing light to mean ‘say again’? • Do any of these choices also appear in flag signaling or radio telephony with the same meaning?

✅ Before You Answer

• Verify which group is listed in the International Code of Signals as the signal for ‘repeat the previous transmission’ or ‘repeat back’ • Check that the choice is a short, standard prosign/abbreviation, not a whole English word • Confirm the selected group is used across multiple signaling methods (flash, flag, radio) with the meaning ‘repeat’ or ‘say again’
