If a chosen frequency is busy, what should you do?

In a maritime communication context, if a chosen frequency is busy, choosing to wait for a clear opportunity to transmit is the most appropriate action. This approach adheres to proper radio etiquette and ensures that communication protocols are respected, which is vital for maintaining safety and avoiding interference with ongoing conversations.

By waiting for a clear moment, you help to prevent overlapping communications that could lead to misunderstandings or missed critical information. The maritime industry operates under strict communication regulations, often influenced by the need for clarity and priority in emergencies or important navigational communication. While the other options might seem like viable choices in a pressing situation, they can cause significant disruption and potentially dangerous situations by adding to the traffic on a busy frequency. Therefore, the correct practice emphasizes patience and respect for the established communication norms.
