Under the Great Lakes Radio Agreement, what minimum credential must ships have for radio operation?

• A. Commercial Radio License
• B. Amateur Radio License
• C. Marine Radio Operator Permit
• D. No certification required

Answer: (C)

The Great Lakes Radio Agreement requires a Marine Radio Operator Permit as the minimum credential for operating a ship’s radio. This agreement between the U.S. and Canada sets a standard so that anyone handling maritime communications on the Great Lakes is credentialed and understands basic radio procedures, safety, and regulatory rules. The Marine Radio Operator Permit is the FCC-issued credential that specifically covers the operation of a ship’s radio on domestic waters. It’s more limited than a full Commercial Radio Operator License, which is a higher-level credential, and an Amateur Radio License is not valid for operating shipboard commercial radio. No certification isn’t acceptable because the agreement requires a recognized credential to ensure proper and safe radio operation.
