When your radio station is off the air temporarily due to technical problems or transmitter issues, you might have an exchange like the one I had with a listener:
Me: (Name of station.)
Listener: Yes, what's wrong with my radio today?
Me: The station is temporarily off the air.
Listener: Oh. It must be the rain.
It wasn't the rain, but I appreciated that the listener cared enough to listen and ask what was wrong. I also appreciated that she didn't ask me to announce on the air that the station was off the air. You'd think that would never happen, but...
