🔍 Key Concepts

• Great Lakes Radio Agreement applicability to certain U.S. and foreign vessels on the Great Lakes • Difference between radiotelegraph and radiotelephone qualifications • Hierarchy of FCC radio licenses: high-level vs. limited/entry-level operator permits

💭 Think About

• Is the Great Lakes Radio Agreement mainly about telegraph operations, telephone operations, or both? How does that affect the class of license needed? • Among the choices, which licenses are designed for more complex or long‑range services, and which are for simpler marine VHF/short‑range operations? • Which of these credentials would be considered the minimum qualification, not a higher one than necessary?

✅ Before You Answer

• Verify which FCC license is explicitly linked in study materials to Great Lakes compulsory radio installations. • Check whether the Agreement requires a radiotelegraph capability or only radiotelephone for the covered ships. • Confirm which license type is identified as the minimum operator requirement for vessels subject to the Great Lakes Radio Agreement, not just any vessel with a radio.
