An LRC radio course imparts both the necessary theoretical knowledge and practical skills in operating the equipment. Typically the training is divided into a theoretical classroom part and practical exercises on the radio.

Theory: In the theoretical training you learn all relevant topics of maritime radio for worldwide shipping. These include among others:

• Radio technology and equipment: Fundamentals of the structure and function of maritime radio equipment, aerials and radio waves (VHF, medium wave, short wave).

• Radio procedures & distress calls: International radiotelephone procedures (such as calls, acknowledgements) as well as distress, urgency and safety messages according to the Global Maritime Distress and Safety System (GMDSS). You learn, for example, the correct procedures for Mayday, Pan Pan and Sécuritécalls.

• Regulations & rulebooks: Important international regulations for maritime radio (e.g. ITU regulations, GMDSS provisions) and the legal framework.

• Navigation & weather by radio: Using radio technology for navigational aids (e.g. bearings) and receiving weather reports and navigational warnings (for example via NAVTEX or SafetyNET).

• Satellite communication: How satellite radio systems such as Inmarsat-C work and their integration into GMDSS for worldwide emergency communication.

Practice: In practical training on the radio equipment you apply the theoretical knowledge. Under instruction you learn in particular:

• Equipment operation: Using typical radio installations for VHF (with DSC), medium/high frequency radio (MF/HF) and satellite radio (Inmarsat). You practise, for example, editing a DSC controller, configuring an Inmarsat-C installation and sending digital radio messages.

• Distress and routine radio: Step by step, transmitting a distress call (distress alert) via DSC and sending a Mayday call by voice radio. You also train in sending urgency and safety messages (Pan Pan / safety message) as well as correctly handling general radio traffic (routine calls between ships or with coast radio stations).

• Running through emergency scenarios: Using case studies you learn how to respond to incoming distress calls. You receive distress or urgency messages (usually in English) and initiate appropriate measures, e.g. acknowledging a received distress call or relaying a distress call to other stations. Terminating distress traffic and cancelling false alarms are also practised.

• Satellite and data radio: Specifically for the Inmarsat system you also practise triggering distress calls (Distress) and sending, for example, telex messages. You also learn to receive weather and navigational messages via services such as Navtex/SafetyNET.

A good LRC course places great emphasis on practical exercises – often using genuine radio equipment or simulators, so that you can operate the radio confidently and routinely in an emergency. This ensures you are optimally prepared for the examination tasks.

A Long Range Certificate brings many advantages for ocean sailors – and in certain cases it is even legally required. Here are the main reasons why the LRC radio certificate is worthwhile:

• Legal requirement for certain radio installations: The LRC is mandatory as soon as a medium/high frequency or satellite radio installation is fitted on board. In this case at least one crew member must hold a valid LRC radio certificate. (This typically applies to yachts operating on the high seas and having the relevant radio equipment on board.)

• Worldwide range: With the LRC you can maintain radio contact even far away from the coast. Unlike pure VHF radio (range approx. 30 nm), the LRC enables communication via short/medium wave and satellite over thousands of nautical miles. This way you stay in contact with coast stations, weather services or other ships even on ocean passages – no matter how far away you are.

• Rapid help in emergencies: In the event of serious problems on board (accident, water ingress, dismasting etc.) with the LRC you can immediately send a distress call and alert rescue services – even in the middle of the high seas where no mobile phone coverage exists. This can be life-saving: through the worldwide distress frequency you always reach a coordination centre or a ship nearby.

• Up-to-date information underway: Via short wave and satellite radio you receive important nautical information in real time, e.g. weather reports, gale warnings or navigational warnings for your sea area. Especially on long passages it is essential to receive weather messages early in order to adjust course and sail setting accordingly.

• Internationally recognised certificate: The LRC radio certificate is valid worldwide and is accepted by most countries as an official certificate of competence. So if you charter a boat abroad or sail in foreign territorial waters, the LRC serves as recognised proof of your radio competence. This way you comply with all regulations internationally as well and are on the safe side.

In summary: With the LRC you are equipped for all eventualitiesas soon as you venture beyond coastal range. Often the certificate is not only sensible but indispensable for safe sailing on worldwide trips.

What is the difference between SRC and LRC?

The SRC radio certificate (Short Range Certificate) authorises you for voice radio on VHF in coastal waters – typically up to about 30–35 nautical miles from the coast. The LRC (Long Range Certificate) extends this authorisation and additionally covers short wave and satellite radio in order to communicate across entire oceans. With the LRC you are therefore authorised worldwide (GMDSS maritime radio in sea areas A1 to A4), while the SRC is limited to VHF coastal radio. The LRC automatically includes the SRC; if you hold the LRC you no longer need a separate SRC certificate.

Do I need an SRC to do the LRC?

No, you do not need to already hold the SRC in order to obtain the LRC radio certificate. You can sit the LRC examination directly – in which case the SRC examination is simply taken at the same time, since the LRC builds upon it. However, if you already have an SRC certificate you can often sit a shorter supplementary examination covering only the LRC-specific part. In both cases you receive the full LRC radio certificate (including SRC authorisation) at the end.

How good does my English need to be for the LRC?

You do not need perfect English, but basic English skills are necessary. The general radio language is English – this becomes particularly apparent in the LRC examination, where, for example, a distress call is dictated in English. More important than fluent conversation is mastery of the basic radio phrases (Mayday, Pan Pan, etc.) and the phonetic alphabet. The required vocabulary and phrases in maritime radio are manageable and can be learnt systematically. With solid basic knowledge and a bit of practice you can master the English parts of the examination.

How much does the LRC radio certificate cost?

There are examination fees for the official LRC examination. These comprise the admission fee, the theory and practical examination fee, and the fee for issuing the radio certificate. Overall the examination costs currently amount to around €187 (as of 2025). There may also be course fees if you take an LRC radio course at a sailing school – these vary by provider (an intensive preparation course can cost several hundred euros). At toernfinder.de you can compare the prices and services of various course providers impartially.

How long is the LRC radio certificate valid?

The LRC radio certificate is valid indefinitely. Once passed, you do not need to renew or refresh the certificate – it retains its validity for life. A German LRC is also recognised abroad without time limit. It is of course advisable to keep your radio skills up to date through practice and refresher courses where appropriate, but the document itself does not expire.
