📻 VHF RADIO FREQUENCY – The Lifeline of Marine Communication

VHF (Very High Frequency) radio is the primary communication tool on every vessel. Understanding its frequency range and key channels is essential for safe navigation and emergency response.

**Frequency Range: 156-174 MHz**
Marine VHF operates in the VHF band between 156 and 174 megahertz. This frequency range provides reliable line-of-sight communication with a typical range of 20-30 nautical miles, depending on antenna height and atmospheric conditions.

**Channel 16 (156.8 MHz) – The Emergency Frequency**
Channel 16 is the international distress, safety, and calling frequency. It's monitored 24/7 by coast guards, rescue services, and all vessels at sea. Any distress call—Mayday, Pan-Pan, or Securité—must be transmitted on Channel 16. It's also used for initial contact before switching to a working channel.

**Channel 13 (156.65 MHz) – Bridge-to-Bridge**
Channel 13 is designated for ship-to-ship navigation safety communications, especially when vessels are in sight of each other. It's used for coordinating passing arrangements, discussing navigation intentions, and preventing collisions in congested waters or narrow channels.

**Channel 6 (156.3 MHz) – Ship-to-Ship**
Channel 6 is the primary inter-ship communication channel for routine operational messages. After initial contact on Channel 16, vessels often switch to Channel 6 for non-urgent conversations to keep the distress frequency clear.

**Why VHF Matters**
VHF provides instant voice communication without relying on satellites or cellular networks. It's simple, reliable, and works in all weather conditions. Every vessel must carry a functioning VHF radio, and crew must know how to use it—especially Channel 16 for emergencies.

ShipSmith ensures your VHF equipment is properly installed, maintained, and compliant with GMDSS requirements.
