Which of the following statements is true?

Question 1 of 29218

Q

Which of the following statements is true?

🔍 Key Concepts

• VHF channel designations: INT (International) vs USA settings and how they affect channel use • Simplex vs duplex operation on VHF marine radios • Which channels are normally used for USCG contact and which for Bridge-to-Bridge (e.g., Ch-13, Ch-16, Ch-22A)

💭 Think About

• Think about which channels are affected when you switch your radio between INT and USA settings. Does this change how certain channels operate (simplex vs duplex)? • Consider what channel the U.S. Coast Guard expects you to call on initially, and what channel they might shift you to afterward. • Ask yourself whether using the INT setting would actually stop you from talking properly on Ch-13 Bridge-to-Bridge when operating in U.S. waters.

✅ Before You Answer

• Verify which VHF channel is the primary calling and distress frequency used to contact the U.S. Coast Guard. • Check which channels change between simplex and duplex when toggling between INT and USA (pay attention to public correspondence / ship-to-shore channels). • Confirm that Ch-13 Bridge-to-Bridge operation requirements and whether they depend on INT vs USA settings.
