What does the term 'OVER' signify in a radio transmission?

The term 'OVER' in a radio transmission indicates that the transmission is complete and the sender is expecting a reply. This word serves as a cue for the recipient that the speaker has finished their message and is awaiting feedback or acknowledgment. The use of 'OVER' helps to promote clarity in communication, avoiding confusion about when one party's message has ended and ensuring that both parties are aware of the state of the conversation.

In radio communications, clear terms are essential since operators often work in noisy or distracting environments. Saying 'OVER' eliminates ambiguity, allowing the receiving party to know that it is their turn to respond. This practice is fundamental for effective two-way communication, especially in emergency situations where miscommunication could have serious consequences.

Using 'OVER' also helps to structure the communication process, making it easier to manage exchanges and maintain orderly conversation in which multiple parties might be involved.
