FCC commercial operator rules

The FCC Restricted GMDSS Radio Operator's License (RG) is an entry-level commercial maritime radio license for operators on compulsory ships sailing exclusively within Sea Area A1 (VHF DSC coverage of the coast, about 20-30 NM). Candidates pass two written, multiple-choice elements administered by a COLEM: Element 1, Basic Radio Law and Operating Practice (24 questions, pass 18 of 24, 75%), and Element 7R, Restricted GMDSS Radio Operating Practices (50 questions, pass 38 of 50, 76%). Element 7R covers DSC alerting on VHF Channel 70 (156.525 MHz) with voice follow-up on Channel 16, the nine-digit MMSI, MAYDAY/PAN PAN/SECURITE procedures, false-alert cancellation, distress relays, the 406 MHz EPIRB and COSPAS-SARSAT, the 9 GHz radar-SART, NAVTEX on 518 kHz, and SOLAS Sea Area A1 carriage and watchkeeping. Element 1 covers 47 CFR Part 80 radio law, station and operator licensing, and basic VHF operating practice. The RG is valid for the holder's lifetime and is more limited than the full GMDSS (DO) license.

1The Restricted GMDSS Radio Operator's License (RG) authorizes operation of GMDSS radio installations on compulsory ships sailing exclusively within which sea area?
A.Sea Area A2
B.Sea Area A3
C.Sea Area A1
D.Sea Area A4
Explanation: The RG license is limited to vessels operating exclusively within Sea Area A1, the VHF DSC coverage area extending roughly 20 to 30 nautical miles from a coast station. Full GMDSS Radio Operator licenses are required for A2/A3/A4 voyages.
2Sea Area A1 is defined as the radiotelephone coverage area of at least one VHF coast station in which what service is continuously available?
A.MF DSC alerting
B.VHF DSC alerting
C.HF radiotelex
D.Inmarsat-C EGC
Explanation: Sea Area A1 is an area within the radiotelephone coverage of at least one VHF coast station in which continuous DSC (Channel 70) alerting is available. This is the only sea area in which an RG-licensed operator may sail.
3Which VHF channel is designated for Digital Selective Calling (DSC) for distress, urgency, safety, and routine calling?
A.Channel 16
B.Channel 13
C.Channel 6
D.Channel 70
Explanation: VHF Channel 70 (156.525 MHz) is reserved exclusively for DSC, including distress, urgency, safety and routine alerting. No voice transmissions are permitted on Channel 70.
4After transmitting a DSC distress alert on VHF Channel 70, on which channel should the operator make the subsequent distress voice transmission?
A.Channel 70
B.Channel 16
C.Channel 13
D.Channel 9
Explanation: Once a DSC distress alert is sent on Channel 70, the operator switches to Channel 16 and transmits the distress message by voice, beginning with MAYDAY. Channel 16 is the associated radiotelephone distress and safety frequency for VHF DSC.
5What is the proper procedure to follow upon receipt of a distress alert transmitted by Digital Selective Calling?
A.Immediately retransmit the DSC alert to all stations
B.Set watch on the radiotelephone distress and safety frequency associated with the calling frequency on which the alert was received
C.Acknowledge the alert by DSC immediately to stop the alert
D.Ignore the alert unless your vessel is the nearest ship
Explanation: On receiving a DSC distress alert, the operator sets a watch on the radiotelephone distress and safety frequency (Channel 16 for VHF) associated with the calling frequency on which the alert was received, then listens for the follow-on voice transmission.
6A 406 MHz satellite EPIRB transmits which of the following to the COSPAS-SARSAT system?
A.Continuous voice distress messages
B.NAVTEX safety bulletins
C.A unique digital identification (hex ID), and on some models GPS position data
D.DSC routine calls on Channel 70
Explanation: A 406 MHz EPIRB transmits a unique coded digital identification (hexadecimal ID) registered to the vessel; GPS-equipped models also embed position data, allowing the COSPAS-SARSAT system and RCC to identify and locate the vessel quickly.
7On what frequency does a Search and Rescue Transponder (SART) operate to assist rescuers in locating survivors?
A.121.5 MHz
B.9 GHz (X-band radar frequency)
C.406 MHz
D.156.525 MHz
Explanation: A SART operates in the 9 GHz (X-band, 3 cm) radar frequency band. When interrogated by a ship or aircraft radar, it responds with a series of dots that appear on the radar screen, leading rescuers to the survival craft.
8NAVTEX is an international system for the automatic broadcast of maritime safety information. On what frequency is the international NAVTEX service broadcast?
A.2182 kHz
B.156.8 MHz
C.518 kHz
D.490 kHz
Explanation: The international NAVTEX service is broadcast on 518 kHz in English using narrow-band direct-printing (NBDP). It automatically prints navigational and meteorological warnings and urgent safety information for vessels within coastal range.
9Which one of the following is the correct international procedure (spoken) word that precedes a distress message?
A.PAN PAN
B.SECURITE
C.SEELONCE
D.MAYDAY
Explanation: MAYDAY, spoken three times, indicates grave and imminent danger to a vessel or persons and a request for immediate assistance. It has absolute priority over all other transmissions.
10The spoken word PAN PAN, repeated three times, is used to introduce which category of message?
A.A distress message
B.A safety message
C.An urgency message
D.A routine traffic message
Explanation: PAN PAN (spoken three times) introduces an urgency message concerning the safety of a ship or person, such as a man overboard or a medical emergency, where there is no grave and imminent danger requiring immediate assistance.

About the FCC Restricted GMDSS (RG) Exam

The FCC Restricted GMDSS Radio Operator's License (RG) authorizes an operator to use Global Maritime Distress and Safety System (GMDSS) radio installations aboard compulsorily equipped ships that sail exclusively within Sea Area A1, the VHF Digital Selective Calling coverage area of a coast station (roughly 20-30 nautical miles offshore). It is earned by passing written Element 1 (Basic Radio Law and Operating Practice) and Element 7R (Restricted GMDSS Radio Operating Practices), both administered by FCC-certified COLEMs from public question pools. The RG is a lifetime license and is narrower than the full GMDSS Radio Operator's License (DO), which authorizes operation in all sea areas using MF, HF, and satellite communications.

FCC Restricted GMDSS (RG) Study Tips from Top Performers

1Memorize the passing thresholds: Element 1 requires 18 of 24 correct (75%) and Element 7R requires 38 of 50 correct (76%); aim well above these on practice sets
2Lock down the channel facts: Channel 70 (156.525 MHz) is DSC-only, Channel 16 (156.800 MHz) is the voice distress/calling channel, Channel 13 is bridge-to-bridge at 1 watt, and Channel 22A is the U.S. Coast Guard liaison channel
3Know the device frequencies cold: 406 MHz EPIRB to COSPAS-SARSAT, 9 GHz X-band radar-SART, and NAVTEX on 518 kHz; mixing these up is a common exam mistake
4Understand the distress sequence: send the DSC alert on Channel 70 (with MMSI, position, time and nature of distress), then complete by voice on Channel 16 starting with MAYDAY repeated three times
5Practice the priority order MAYDAY (distress) > PAN PAN (urgency) > SECURITE (safety) > routine, and what SEELONCE MAYDAY and SEELONCE FEENEE mean
6Review Sea Area A1 (VHF DSC, about 20-30 NM) versus A2 (MF), A3 (Inmarsat satellite) and A4 (polar) so you can identify the RG license scope and the minimum SOLAS carriage for A1

Frequently Asked Questions

What does the FCC Restricted GMDSS Radio Operator's License (RG) allow?

The RG authorizes operation of GMDSS radio installations aboard compulsorily equipped ships that sail exclusively within Sea Area A1, the VHF Digital Selective Calling coverage area of a coast station, roughly 20-30 nautical miles from shore. Voyages requiring MF, HF, or satellite communications need the full GMDSS (DO) license.

Which exam elements must I pass for the RG?

You must pass two written elements: Element 1 (Basic Radio Law and Operating Practice), which has 24 questions and requires 18 correct (75%), and Element 7R (Restricted GMDSS Radio Operating Practices), which has 50 questions and requires 38 correct (76%).

Who administers the RG examination?

FCC commercial operator exams are administered by Commercial Operator License Examination Managers (COLEMs), private companies certified by the FCC. COLEMs build the tests from the public FCC question pools and may proctor remotely or in person.

How long is the RG license valid?

Like most FCC commercial radio operator licenses, the Restricted GMDSS Radio Operator's License is issued for the lifetime of the holder and does not require periodic renewal.

What is the difference between Channel 70 and Channel 16?

VHF Channel 70 (156.525 MHz) is reserved exclusively for Digital Selective Calling and carries no voice. After sending a DSC distress alert on Channel 70, the operator switches to Channel 16 (156.800 MHz) to transmit the MAYDAY and distress message by voice.

What should I do if I send a false DSC distress alert?

Immediately cancel the false alert by voice on Channel 16, giving your ship's name, call sign and/or MMSI, your position, and a clear statement that the distress alert was sent in error and is cancelled. Transmitting a false distress is otherwise subject to substantial penalties.

How much does it cost to get the RG?

Expect a $35 FCC application fee plus the COLEM's exam fees, which commonly run about $25-$75 per element. Total cost varies by the COLEM you choose and whether you test the elements together.
