What is the recommended transmission power when transmitting in a harbor?

The recommended transmission power when transmitting in a harbor is 1 watt or low power due to several important reasons. In confined areas like harbors, it's essential to minimize the risk of interference and ensure that communications are clear and focused. Lower power levels help reduce the potential for radio frequency congestion, which is vital in busy maritime environments where multiple vessels and shore stations are operating in close proximity.

Using low power also helps to preserve battery life for handheld or portable radio equipment, which is often used in these conditions. Additionally, broadcasting at lower power minimizes the likelihood of unintentionally transmitting signals that could interfere with other communications or safety systems in the area, thus promoting safer navigation and operation in congested waterways.

This practice aligns with recommended protocols for maritime communication, especially in regions where many vessels are operating simultaneously, making it a standard approach to ensure effective and safe communication.
