The use of "over" in radio communications dates back to the early days of Morse code, when it was used to indicate the end of a transmission. It has since been adopted by voice radio communications as well, and is now considered standard practice.
By saying "over," a speaker is essentially saying, "I'm done talking, please respond." It is a way of ensuring that communication is clear and efficient, and helps to avoid misunderstandings.
Here are a few examples of how "over" might be used in a radio conversation:
* Speaker 1: "This is Base Camp to Mountain Team, over."
* Speaker 2: "Mountain Team here, go ahead Base Camp, over."
* Speaker 1: "We have a situation developing here at Base Camp, need assistance, over."
* Speaker 2: "Roger that Base Camp, we're on our way, over."
In this example, "over" is used to indicate the end of each transmission, and to signal to the other person that it is their turn to talk. This helps to keep the conversation organized and flowing smoothly.
By adhering to standard communication practices like using "over," radio users can help to ensure that their messages are received clearly and that communication is effective.
