How many watts is channel 16 typically?

Channel 16, which is the international distress, safety, and calling frequency used in VHF marine radio communications, is typically limited to a maximum output of 25 watts. This wattage allows for effective communication over moderate distances without causing undue interference to other channels or users.

Using 25 watts ensures that vessels can transmit important safety information and alerts, while still adhering to regulations that maintain order within the maritime communication spectrum. The device’s power output is significant as it determines the effective range of communication. Higher wattages are reserved for other uses and can lead to issues such as signal overlap and interference, which is why Channel 16 is standardized to this output for safety and operational efficiency on the water.
