What is the recommended power output for transmitting in a harbor?

Choosing a power output of 1 watt or low power for transmitting in a harbor is recommended for several reasons related to safety, interference management, and regulatory compliance.

Harbors are typically busy areas with numerous vessels operating in close proximity, which increases the potential for radio frequency interference. Using lower power reduces the transmission range, minimizing the chance of signal overlap and ensuring clearer communications among vessels without overwhelming them with excessive signal strength.

Additionally, lower power settings help to comply with regulations that often dictate maximum allowable transmission power in congested areas to avoid interference with other communications systems, including those used by harbormasters and emergency services. This conscious effort to limit power output contributes to a safer navigational environment.

In contrast, higher power outputs can create a significant risk of interference, which can disrupt safe operations in such crowded and complex environments. Therefore, using low power in harbor areas is both a best practice for effective communication and a safety measure to prevent disruptions and maintain clear channels for all vessels operating in the vicinity.
