What transmitting equipment is authorized for use by a station in the maritime services?

• A. Any transmitting equipment
• B. Unless specifically excepted, only transmitters certified by the FCC for Part 80
• C. Transmitters certified for Part 90
• D. Transceivers licensed by the ship's owner

Answer: (B)

In the maritime service, the transmitting gear you use must be FCC-certified for Part 80, unless an explicit exception applies. This certification shows the equipment meets the specific maritime rules for operating frequencies, power levels, and emission limits, helping prevent interference and ensure safe, reliable communications at sea. Therefore, you can't use just any transmitter or gear certified for another service; it must have Part 80 certification. Transmitters certified for Part 90 apply to land mobile systems, not maritime use, and ownership of a transceiver by the ship’s operator does not override the certification requirement.
