Nautical VHF radio: frequencies, coverage, and usage
The marine VHF band spans 156–162 MHz and is divided into internationally standardized channels: channel 16 for distress and calling, channel 70 for Digital Selective Calling (DSC), and dedicated channels for port operations and ship-to-ship communications. Coverage is line-of-sight and depends chiefly on antenna height, geography, and equipment quality — a fixed radio with a properly elevated antenna reaches 20–25 nautical miles in open water.
