Question for anyone who monitors Barnstable County regularly. I was going through some recordings from 2019. There was a message about Capt. Kenney, may God rest his soul. Can someone explain the chirping sounds.
Those are keying tones that are sent from the dispatch console to the transmitting radio to tell it to key up. Normally, the transmitting radio will filter these tones out so that they don't go over the air.
