What is the purpose of the "Echo Procedure" in radio transmissions?

The purpose of the "Echo Procedure" in radio transmissions is primarily to verify signal strength and ensure clarity of communication between units. This procedure involves the sender repeating a message after it has been transmitted, allowing the receiving party to confirm that they have accurately received the information. By doing so, it helps identify any potential issues with the transmission, such as interference or degradation of the signal, which can be critical in high-stakes environments like public safety communications.

Using the Echo Procedure ensures that crucial information is conveyed accurately, particularly in situations that require immediate action or response from emergency services. It plays a fundamental role in maintaining the integrity of communication in public safety operations.
