Which of the following is NOT a requirement for LHG communication?

The primary focus of LHG (Local Harbor Guidelines) communication is to ensure effective and reliable communication for operations in potentially hazardous maritime environments. Requirements for LHG communication prioritize clarity, reliability, and adaptability in various conditions, which is why the other choices involve essential aspects of successful communication.

The requirement for communication to be effective in all weather conditions ensures that vessels can safely communicate regardless of external factors like storms or fog. This reliability is crucial for navigation and operational safety.

Continuous two-way voice communication emphasizes the need for ongoing dialogue, enabling immediate response and coordination between vessels and shore facilities. This is vital for managing operations and safety protocols in real time.

The requirement for the use of fixed or portable phones facilitates communication flexibility and accessibility, allowing crew members to communicate regardless of their location on a vessel.

In contrast, the use of outdated radio equipment would not support the requirements for effective communication in modern maritime operations. Communication systems need to be current, utilizing technology that meets safety standards and provides clear transmission. Therefore, outdated equipment would not be suitable within this context, making it the correct answer for what is NOT a requirement for LHG communication.
