What is the output power for Channel 13?

Channel 13, which is used for intership communications on the VHF marine band, has a maximum output power limit of 1 watt for communications. This limitation is put in place to promote safe and effective communication between vessels, particularly in close quarters, to minimize interference with other channels and systems.

When operating on Channel 13, which is often used for navigational purposes, such as bridge communications, the 1 watt output power helps ensure that signals can be transmitted effectively over short distances without causing unnecessary disruption to other users of the radio spectrum.

In contrast, other channels might have higher power options, but for Channel 13, staying within the 1 watt limit is essential for regulatory compliance and maintaining good marine communication practices.
