Marine Radio Short Range Operator Certificate of Proficiency (SROCP)

The Short Range Operator Certificate of Proficiency (SROCP) is an internationally recognised qualification for using a VHF marine radio. In Australia, the exam is run by the Australian Maritime College's Office of Maritime Communications (OMC). For most recreational sailors who carry a VHF, the SROCP is the qualification to get, especially if you plan to sail overseas or charter abroad.

Who it suits

• Skippers and crew of boats fitted with a VHF radio, fixed or handheld
• Offshore racers and coastal cruisers, often alongside the Safety and Sea Survival Course
• Australians planning to charter or cruise overseas who need an internationally recognised radio qualification
• Anyone who wants to use DSC safely, including the distress button

You must be at least 16 to sit the exam.

What you'll actually do

You can study on your own using the Marine Radio Operators Handbook (the OMC also publishes a shorter VHF-only handbook), or you can attend a course with a training provider. Either way, you sit the exam under a registered invigilator. It's a closed-book, multiple-choice paper lasting half an hour, and the pass mark is 70%. Courses usually include hands-on practice with a VHF/DSC set. Ask your provider how any practical assessment is run. The certificate is a photo card and does not need renewing.

The syllabus covers VHF radiotelephony with digital selective calling (DSC), 406 MHz distress beacons, distress, urgency and safety procedures, basic care of the equipment and the regulations for ship stations.

Key ideas explained

• Channels 16 and 67 in Australia: channel 16 is the international distress and calling channel. You make first contact there, then move to a working channel. According to the ACMA's marine radio procedures, in Australian waters you use channel 16 or 67 for distress transmissions on VHF.
• DSC (digital selective calling): a digital "ring" sent on VHF channel 70. It can call a specific station, all stations, or send a distress alert at the press of a button. If your GPS is connected, the alert includes your position. After a DSC distress alert, follow up with a spoken Mayday on channel 16.
• MMSI: a nine-digit Maritime Mobile Service Identity, which is your radio's "phone number". It must be programmed into a DSC radio before it can send an alert that identifies your boat. In Australia, MMSIs are issued by AMSA.
• Mayday: for grave and imminent danger to a vessel or person that needs immediate help. Say "Mayday" three times, then "this is" and your boat's name three times. Then give "Mayday", the boat's name, position, the problem, the help you need, the number of people on board and any other useful information, and finish with "over".
• Pan-Pan and Sécurité: Pan-Pan (said three times) is an urgent message about the safety of a vessel or person that is not grave and imminent, such as a dismasting with no immediate danger or a medical issue. Sécurité (pronounced "say-cure-ee-tay") is a safety message, such as a navigation hazard or weather warning.
• Radio discipline: listen before you transmit, keep messages short, use standard phrases and the phonetic alphabet, and never make false distress calls.

Where it fits

• Lower level: the ACMA also lists an Australian Waters Qualification (AWQ) for boaters who only use their VHF in Australian waters. The SROCP is the internationally recognised step up.
• Higher level: the Long Range Operator Certificate of Proficiency (LROCP) covers HF as well as VHF, for bluewater and ocean passages.
• Pairs well with: Keelboat Start Skippering, Safety and Sea Survival, and overseas skipper courses such as RYA Day Skipper Practical.

The SROCP is broadly comparable to the RYA's Short Range Certificate. Both are ITU-based VHF/DSC qualifications, but always check what a charter company or foreign authority will accept.

Getting ready

• Get the handbook early and work through the VHF sections and revision questions.
• Practise saying a Mayday and a Pan-Pan out loud, and learn the phonetic alphabet.
• If you own a DSC radio, find out whether an MMSI is programmed in and how to send a test or routine call. Read the manual.
• Ask a course provider whether the exam is included, who the invigilator is, and whether handbook costs are included.

Good to know in Australia

According to the ACMA, everyone who operates a marine radio in Australia needs an appropriate qualification, except for 27 MHz sets. Holding a DSC-equipped radio does not remove that requirement.
