When should the word 'over' be omitted from a message?

The word 'over' is typically used in radio communication to indicate that a speaker has finished their transmission and is awaiting a response from the receiver. It serves as a cue for the other party to respond. Therefore, in circumstances where a message clearly requires a reply, using the term 'over' is unnecessary because the context implies that the communication requires further interaction.

In contrast, if a message does not require a reply or is a final statement, such as a piece of information being communicated without anticipation of a response, omitting 'over' can be appropriate. Similarly, in the case of relaying information, 'over' may not be relevant if the intention is to provide a transmission without expecting acknowledgment or further dialogue. Thus, the use of 'over' is best reserved for contexts where it clearly signals a need for engagement, making its omission appropriate when a reply is already implied or needed.
