What does the term 'OUT' indicate at the end of a transmission?

The term 'OUT' at the end of a transmission signifies that the communication is complete and no further response is expected from the recipient. This term is a standard in radio communication protocols, indicating to the receiver that there is no ongoing dialogue, and the operator is finished conveying their message. By using 'OUT,' the operator clearly communicates a definitive end to the conversation, allowing both parties to understand that they do not need to reply or take further action regarding that particular exchange. This clarity helps to maintain efficient communication, especially in environments where clarity and brevity are crucial, such as during emergencies or coordinating activities on the water.
