radio check
Signal confirmation request
Radio check is a brief transmission to verify that a radio is working and the signal is being received clearly.
Common in military, aviation, and emergency services, it typically expects a response confirming signal strength and clarity: Radio check, how do you read me?
The reply often uses a scale: I read you five by five or loud and clear.
