At what wattage should channel 13 be operated?

Channel 13, which is specifically designated for navigational safety, is utilized primarily for communication between vessels and between vessels and shore stations. The operational wattage for this channel is set at 1 watt for most situations, because the intention is to maintain clear and concise communication over short distances without causing interference to other channels or stations.

Using 1 watt ensures that the functions of channel 13, which include ship-to-ship communications, are performed effectively, allowing vessels to communicate their intentions and navigational information in a manner that is efficient and minimizes the risk of overcrowding the channel. This low power level is more than sufficient for the required range of communications typically associated with vessel navigation.

Operating at higher wattages on this channel could lead to unnecessary interference and could complicate communications, which is why 1 watt is the appropriate standard for channel 13.
