Understanding Scanning
18
CTCSS and DCS are also used in areas that receive
interference where there are several stations with
output frequencies close to each other. When this
occurs, you might hear multiple communications on
the same 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.
