VHF Radio
A communication device that operates on Very High Frequency (VHF) radio waves, used for ship-to-ship, ship-to-shore, and emergency maritime communication.
VHF radios are essential for marine communication, providing a reliable means of contact between vessels, harbours, marinas, and emergency services. They operate on frequencies between 156 and 174 MHz, offering clear, short-range communication that is less affected by atmospheric interference than lower-frequency radios. VHF radios are required by law on many vessels and are a primary tool for safety at sea, allowing mariners to send distress calls, receive weather updates, and coordinate navigation with other boats.
Marine VHF radios have dedicated channels, with Channel 16 being the international distress and calling frequency. Other channels are designated for specific uses, such as port operations, ship movements, and weather broadcasts. Many modern VHF radios include Digital Selective Calling (DSC), which enables automated distress signalling with GPS location data.
Unlike mobile phones, VHF radios provide instant communication without relying on network coverage, making them indispensable for both commercial and recreational boating.
