English version - VHF-simulator

The VHF simulator is designed so you may practice and learn how to use the basic functions on a VHF, and what purpose the VHF radio serves. The goal is that you by practicing, learn how to use DSC functionality and basic distress and speech procedures.

When you perform the tasks given, you get a response from another part, e.g. coastal radio or another vessel. If your answer is wrong, you get a tip on how to answer correctly. Please note that some functions is not available, such as the squelch and volume (which are not to be used in the tasks on the simulator). But remember; the best way to learn how to use a VHF radio, is to actually use one…

The VHF simulator has menus like real VHF-radios. Even though appearance and buttons on the VHF radios differ from each other, the menus should be alike, based on international standards (ETSI standards is partly used when designing the VHF simulator).
