What is a requirement for all marine transmitting apparatus used aboard United States vessels?

• A. All such equipment must be U.S.-made
• B. Equipment may be used if it is certified for Part 90 operations
• C. Only equipment certified by the FCC for Part 80 operations is authorized
• D. Equipment need not be certified if under 5 watts

Answer: (C)

The essential rule is that marine transmitting equipment used on U.S. vessels must be FCC-certified for marine use under Part 80. This certification verifies the gear meets the specific marine service requirements for operating frequencies, power, emission limits, and spurious radiation, ensuring safe and interference-free communication at sea. Certification for another service, like Part 90, doesn’t automatically authorize marine use, and a device’s power rating does not waive the need for certification. The origin of the equipment (US-made or not) isn’t the issue; what matters is the FCC Part 80 certification.
