Your scanner can receive transmissions that use these codes. CTCSS and DCS systems all use some form of coded squelch. Coded squelch involves the transmission of a special code signal along with the audio of a radio transmission. A receiver with coded squelch only activates when the received signal has the correct code. This lets many users share a single frequency, and decreases interference caused by distant transmitters on the same channel. In all major metropolitan areas of the United States, every available radio channel is assigned to more than one user. CTCSS TONES The scanner can detect the following 50 CTCSS tones. 67.0Hz 69.3Hz 71.9Hz 74.4Hz 77.0Hz 79.7Hz 82.5Hz 85.4Hz 94.8Hz 97.4Hz 100.0Hz 103.5Hz 107.2Hz 110.9Hz 114.8Hz 118.8Hz 131.8Hz 136.5Hz 141.3Hz 146.2Hz 151.4Hz 156.7Hz 159.8Hz 162.2Hz 171.3Hz 173.8Hz 177.3Hz 179.9Hz 183.5Hz 186.2Hz 189.9Hz 192.8Hz 203.5Hz 206.5Hz 210.7Hz 218.1Hz 225.7Hz 229.1Hz 233.6Hz 241.8Hz 124
