Heading beyond coastal waters? Then the Long Range Certificate (LRC) is your ticket: the general radio operator certificate for worldwide marine communication via shortwave and satellite. This app targets the German LRC theory exam and contains all 76 official questions and answers from the current ELWIS catalogue – the exact pool your exam is assembled from.
Be aware that the app is a German-language product. Since the German exam is based on the German catalogue, all questions, answers and explanations appear in German. English speakers preparing for the LRC in Germany can absolutely use it, but should bring solid German reading comprehension.
Studying is anything but dry flashcard grinding: the traffic-light system sorts questions by how well you know them, each question ships with an explanation, and tricky ones can be flagged for separate review. Progress statistics show you in black and white how close you are to exam readiness. When the date approaches, exam mode puts all 12 official exam sheets in front of you, with the submission timer running at the prescribed exam time. Start with 16 free questions, then unlock the complete catalogue when you are ready to commit.
The app is made for sailors who want more than coastal radio: blue-water cruisers and long-distance crews who need worldwide communication via shortwave and satellite, and SRC holders in Germany upgrading their certificate to the LRC. English-speaking skippers taking the German exam should note that the study material is in German and plan their preparation accordingly.
The LRC (Long Range Certificate) is the general radio operator certificate for worldwide marine radio and extends the SRC with shortwave and satellite communication. In Germany the exam is taken with the examination committees of the DMYV and DSV, and the theory part draws on the official catalogue of 76 questions. The app trains exactly this format with the 12 official exam sheets.
The full official question catalogue for the LRC with all answers, kept current – nothing unexpected will show up on your exam sheet.
Practise with all 12 official ELWIS exam sheets in exam mode, including a submission timer set to the official exam time – real sheets, real time pressure.
Questions, answers and explanations are presented in German, mirroring the official catalogue on which the German LRC exam is based.
Shortwave, satellite communication and operating procedures are explained clearly for each question, so you build genuine understanding instead of memorised answers.
Mark questions that give you trouble and drill them separately, while the traffic-light system moves everything from red to green as you learn.
The entire trainer runs without internet access – on the water, on the train or wherever there is no signal, without using any data.
It is not – the app presents all questions, answers and explanations in German, because it is built on the official German ELWIS catalogue used for the exam. If you cannot read German comfortably, the app will be difficult to use; this English page exists purely to inform you about it.
Anyone planning to communicate beyond VHF range: on long-distance passages, ocean crossings or yachts equipped with shortwave or satellite installations, the LRC is the required general operator certificate. If your radio use stays within coastal waters, the SRC is sufficient.
The SRC is limited to marine VHF and shorter ranges, while the LRC is valid worldwide and includes shortwave and satellite communication – it is effectively the SRC's big sibling for blue-water sailing. If you are starting from zero, we also offer a dedicated SRC app covering that exam's official catalogue.
The usual route runs from SRC to LRC, since the LRC builds on and extends the VHF marine radio content. The exact admission requirements are set by the responsible examination committees, so check with them – in practice, many skippers earn the SRC first and add the LRC once a long voyage becomes concrete.
You can download the app at no cost and work through 16 questions to see whether the learning concept suits you. The complete set of 76 questions and 12 exam sheets is then unlocked via a one-time purchase or a subscription you can cancel anytime.
Very – exam mode uses the 12 official ELWIS exam sheets and runs a submission timer at the officially prescribed exam time. You rehearse with genuine sheets under genuine time pressure, which is the best dress rehearsal you can get before the appointment.
