Listen to live police and fire calls right here on Scanner 911. You’ll hear the live transmission of emergency service communications from Calaveras, Tuolumne and Amador counties as they happen.
How it Works: Radio scanners rapidly rotate through a bank of pre-programmed frequencies, checking for radio traffic on them. When a channel has traffic, the scanner stops on that channel and plays the audio of the radio transmission. When the radio communication stops, the scanner waits up to 4 seconds for replies. If no further radio transmissions are received on that channel within the 4 second delay period, the scanning of all channels resumes.
