What occurs immediately after phasing with a Coast Station on an available channel?

• A. The ship station begins transmitting text
• B. The vessel requests the shore station's answerback
• C. The ship transmits a command to the coast radio station
• D. The coast station transmits GA+? and awaits a command

Answer: (D)

When a ship station successfully phases with a coast station on an available channel, the subsequent action involves the coast station transmitting "GA+" and waiting for a command from the ship. This step is crucial for establishing a two-way communication link, confirming that the coast station is ready to receive and process messages from the vessel. The "GA+" signal indicates that the coast station is prepared to receive a specific message or instruction from the ship station, which is essential for coordinated and effective communication during maritime operations. This process is part of the standardized procedures outlined in the Global Maritime Distress and Safety System (GMDSS), which aims to enhance safety and communication at sea. By following this protocol, the vessel can transmit its requests or messages clearly and efficiently, ensuring that communication channels remain open and organized.
