Study Notes
Marine Transmitting Apparatus
- All marine transmitting devices aboard U.S. vessels must be certified by the FCC for Part 80 operations.
- Equipment is required to be type-accepted by the U.S. Coast Guard for maritime mobile use.
- International Maritime Organization (IMO) certification is not a direct requirement for equipment.
Authorized Transmitting Equipment
- Transmitters approved by the manufacturer for maritime use are authorized, but typically only those certified by the FCC for Part 80 operations are permitted.
- U.S. Coast Guard inspection and approval may apply to certain equipment.
- Compliance with ITU specifications is necessary for transceivers and transmitters in maritime mobile service.
Equipment Requirements for Vessels
- Small passenger vessels sailing 20 to 150 nautical miles from land are required to have an MF-HF SSB Transceiver as additional equipment.
Distress Alert Equipment
- DSC controllers are specifically programmed to initiate distress alerts and calls to individual stations.
Minimum Transmitter Power Levels
- The FCC mandates a minimum of 100 watts for medium-frequency transmitters on vessels that must be equipped.
- The power required to communicate with the nearest public coast station operating on 2182 kHz is also specified.
Shipboard Transmitter Power Limits
- Shipboard transmitters using F3E emission (FM voice) are limited to a maximum carrier power of 25 watts.
Radio Operator Licensing Requirements
- A fixed-tuned ship RADAR station with external controls requires at least a Marine Radio Operator Permit.
- For aircraft communications, a higher license (Marine Radio Operator Permit or above) is needed for operating above 30 MHz allocated to aeronautical mobile services.
Ineligibility for Commercial Licenses
- Individuals unable to communicate in English via telephone may be deemed ineligible for commercial radio operator licenses.
- Restrictions also apply to handicapped persons and foreign maritime operators lacking IMO certification.
Operational Requirements for Passenger Ships
- Passenger ships with GMDSS installations need two operators on board holding appropriate licenses (GMDSS Radio Operator License or Restricted GMDSS Radio Operator License) based on operating areas.
Radio Operator Licensing for Great Lakes
- The minimum requirement for ships under the Great Lakes Radio Agreement is the General Radiotelephone Operator License.
Commercial Operator Duty Requirements
- Every commercial operator in charge of a transmitting system must maintain a copy of their Proof-of-Passing Certificate in the station's records.
