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

The requirement for all marine transmitting apparatus used aboard United States vessels is that only equipment certified by the FCC for Part 80 operations is authorized. This is essential because Part 80 of the FCC regulations specifically governs the use of radio equipment in the maritime services, which includes radio communications for vessels on waterways.

This certification ensures that the equipment meets safety and technical standards, which contributes to the reliability of communication at sea. Ensuring that maritime vessels communicate using certified equipment helps prevent interference with other services and assures compliance with federal regulations designed to promote safety and efficiency on the water.

In practice, this regulation protects not only the vessels equipped with this gear but also enhances maritime safety by ensuring that all communications operate effectively within the established framework.
