frequency. The stations might even interfere with each
other to the point where it is impossible to clearly receive
any of the stations. A scanner equipped with CTCSS and
DCS (like your scanner) can code each received
frequency with a specific CTCSS or DCS frequency.
Then, when you receive multiple signals, you only hear
the transmission with the CTCSS or DCS tone you
programmed. If you do not receive the correct tone with a
signal, the scanner's squelch remains closed and you
hear nothing.
You can search for the following CTCSS frequencies and
DCS codes.
