FUNCTION- CTCSS & DCS
WHAT IS CTCSS AND DCS?
CTCSS (Continuous Tone-Coded Squelch System) and DCS (Digitally Coded Squelch) modify
the transmission signal to allow multiple users to share the same channel without disturbing each
other. This is an important feature on a radio when there are many radio users in the same area.
CTCSS continuously superimposes any one of about 50 low-pitch audio tones on the transmitted
signal, ranging from 67 to 254 Hz.
DCS was designed as the digital replacement for CTCSS. DCS adds a 134.4 bps (sub-audible)
bit stream to the transmitted audio
CTCSS or DCS is enabled by on the radio through selectable sub channels. When CTCSS or
DCS is enabled, incoming signals must be on the same CTCSS or DCS sub channel as the
receiving radio or they will be filtered out.
NOTE:
The CTCSS and DCS Tone Charts can be found on page 17-19 of this instruction manual.
