🔍 Key Concepts

• FCC Part 80 requirements for ships on international voyages • Difference between a certificate and ITU publication lists • Which documents must be carried on board versus just used as references ashore

💭 Think About

• Ask yourself: Does Part 80 require only proof that your ship complies with SOLAS/GMDSS, or does it also require that you physically carry certain ITU lists on board? • Consider whether the same ITU list number (e.g., List VI) can logically describe both radiodetermination/special service stations AND ship call signs. • Think about the purpose of each item: Which of these would a radio operator actually need at sea to identify other stations and verify their own authorization?

✅ Before You Answer

• Verify in 47 CFR Part 80 Subpart W what documents are explicitly required on board for ships subject to the Safety Convention • Check carefully the correct ITU List number for ship call signs versus radiodetermination and special service stations • Confirm whether the Safety Convention certificate alone satisfies documentation requirements, or if additional ITU lists are also mandated
