You bought the VHF, wired it to the masthead antenna, connected it to the GPS for DSC, and stuck the MMSI on the mic with a label maker. Everything works. What most owners forget, or quietly ignore, is that the radio itself is licensed, and so is the person pressing the transmit button. In France, that person needs the Certificat Restreint de Radiotéléphoniste, the CRR, more commonly called the SRC when you're talking about the recreational version. Here is who actually needs it, what the exam looks like, and how to keep your station legal once the paperwork is done.

What the SRC actually is

The SRC (Short Range Certificate) is the recreational operator certificate for maritime VHF, aligned with the CEPT harmonised framework and recognised across most European flag states. In France it is issued by the ANFR (Agence nationale des fréquences), and the exam itself is administered by the ANFR or by approved partners. It authorises you to operate a fixed or portable maritime VHF, including DSC (Digital Selective Calling) functions, on any pleasure vessel.

The full commercial equivalent, the CRR, covers the same ground plus a bit more (MF/HF radiotelephony basics, more procedural depth). For a private skipper on a sailing yacht or a motor cruiser working within VHF range of the coast, the SRC is what you want. It is a lifetime certificate. No renewal, no recurrent exam. Lose the paper and the ANFR can reissue it against your file.

Who legally needs one

The rule most people miss : the moment you have a fixed marine VHF installed on board, the station is licensed to the boat, and at least one person aboard needs an operator certificate to use it. That applies whether you use the radio once a year or every weekend. Handheld VHF is where things get murkier, and the answer depends on the type of device.

  • Fixed VHF with or without DSC : operator certificate required. The station is declared, gets a call sign and an MMSI, and appears on your ship's papers.
  • Portable VHF with its own MMSI and DSC : same regime. It is a station in its own right and needs to be declared.
  • Simple handheld VHF, no DSC, no dedicated MMSI : in French practice this is tolerated as a secondary safety device without individual certification, provided a licensed operator is aboard when it is used. Do not treat that tolerance as a workaround. If it is your only radio, you are on thin ice with a controller.

The boat licence (permis plaisance) does not include VHF authority. This trips up a lot of new owners : you can legally drive the boat but not legally key the mic. If you are unsure which ticket covers what, it is worth reading up on what boat licence you actually need to sail at sea alongside the SRC question, because they are two separate regulatory tracks.

For anyone planning to sail beyond French waters, the SRC is also part of the paperwork stack you should carry. The documents you need for cross-border navigation include the operator certificate and the ship station licence, and coastguards in Spain, Italy or Croatia will occasionally ask.

What the exam covers

The SRC exam is a written multiple-choice paper of roughly 30 minutes, plus a short practical on a VHF simulator. The pass mark is high (typically around 70 percent, with an automatic fail on any distress-related error). The syllabus is narrow but strict :

  • VHF channel plan : the 55 international channels, dual-watch, duplex vs simplex, and which channels are for what (16, 70, 13, 6, port operations, marina working channels, ship-to-ship).
  • DSC procedure : how to compose and send a distress alert, urgency and safety alerts, individual and all-ships calls, cancelling a false alarm.
  • Voice procedure : phonetic alphabet, MAYDAY / PAN-PAN / SÉCURITÉ structure, MAYDAY relay, message priorities.
  • Regulatory basics : silence periods, secrecy of correspondence, prohibited transmissions, the role of MRCC and CROSS in France.
  • GMDSS overview : sea areas A1 to A4, EPIRB, SART, NAVTEX, and where VHF fits in the wider distress system.

The DSC and distress sections are where most candidates lose points. Examiners want to see that if a real MAYDAY happens, you know the exact sequence : press the dedicated distress button (usually a red flap you lift and hold three to five seconds), wait for acknowledgement, then follow up on channel 16 with the MAYDAY voice message including position, nature of distress, number of people on board and assistance required. Get that muscle memory right in the simulator and the paper is manageable.

If distress equipment as a whole feels fuzzy, the choice between an EPIRB, a PLB or an AIS beacon is worth reading before the exam. It clarifies why VHF DSC is only your first ring in a layered system, not the whole solution.

How to register and take the exam

The process in France is straightforward but administrative, and the different steps confuse people because they involve different bodies.

  1. Study. Budget 10 to 15 hours of self-study. There are online prep platforms with mock exams that mirror the ANFR question bank closely. A weekend of focused work is realistic if you already know the basics of marine electronics.
  2. Register with the ANFR. You create an account on the ANFR portal, pay the exam fee (around 78 euros at time of writing, check the current tariff), and pick a session. Sessions run regularly in most large coastal cities and increasingly in inland centres.
  3. Sit the exam. Bring ID. The theory is on a computer, the practical is on a bench-mounted VHF simulator with a real DSC controller. You get the result on the spot.
  4. Receive the certificate. The paper certificate arrives by post within a few weeks. Keep it with the ship's papers.

If you want a serious head start and a structured route, the same schools that offer intensive boat licence courses often bundle SRC prep. The logic is the same as when you're trying to get your boat licence quickly : a compressed weekend format works if you commit to the theory beforehand.

Registering your radio station

Passing the exam is only half the job. The radio itself has to be declared. In France this is done through the ANFR, again online, and it produces two things :

  • A ship station licence (licence de station de navire), which is the legal authorisation for the equipment on that specific hull. Keep it on board.
  • An MMSI (Maritime Mobile Service Identity), the nine-digit number you program into the radio for DSC. In France, MMSIs start with 226, 227 or 228. If you change flag, you change MMSI. This is one of the practical costs to keep in mind when people talk about registering under a foreign flag : the whole radio identity moves with the flag.

Two important details. First, the MMSI is tied to the boat, not to you. Sell the boat, transfer the MMSI to the new owner via the ANFR (or, more cleanly, they get their own). Never reuse an MMSI on a different hull. Second, if you add an AIS transponder later, it broadcasts the same MMSI as the VHF. If you have DSC-equipped handhelds with their own MMSI, program them as associated devices, not as duplicates.

The station licence sits alongside your other mandatory paperwork. On a French-flagged boat that means the acte de francisation or the carte de circulation, your insurance certificate, and the safety inventory required under Division 240. If you are still assembling that stack, the Division 240 guide lays out exactly what has to be aboard for each navigation zone, and the VHF appears explicitly on the list once you go beyond 6 miles from shelter.

Using it properly at sea

Once the paperwork is done, the discipline matters more than the certificate. A few habits that separate a clean station from a nuisance one :

  • Keep channel 16 monitored underway. Dual-watch with your working channel is fine, scan mode across everything is usually not.
  • Do a monthly DSC self-test. Most radios have a built-in function that does not transmit. Actual test calls to another station should be pre-arranged, not fired at the coastguard.
  • Check that the MMSI is programmed and that the GPS feed is live. A DSC distress with no position degrades your call to the point of near uselessness.
  • If you accidentally trigger a distress alert, do not switch the radio off. Cancel it on DSC, then make a voice call on 16 stating clearly that it was a false alarm, your vessel name, MMSI and position. CROSS will thank you for the honesty.
  • Learn the local working channels wherever you cruise. Marina channels vary, port control channels vary, and getting it wrong in a busy harbour is a fast way to be noticed for the wrong reasons.

The SRC is one of those tickets that feels bureaucratic until the day you need it, and then you are very glad that pressing the red button is a reflex and not a puzzle. Combined with a properly declared station, a live GPS feed and a crew that knows the MAYDAY structure, your VHF becomes the first and fastest link in the rescue chain. Everything else on board, from the logbook to the engine data your onboard electronics quietly record for you, is there to make what happens next easier to explain.
