CTCSS typically decodes in about 250ms or less. When decoding DCS on very weak signals, the DCS decode threshold can be as much as 2 dB worse than CTCSS. DCS (Digital-Coded Squelch), generically known as CDCSS (Continuous Digital-Coded Squelch System), was designed as the digital replacement for CTCSS. In the same way that a single CTCSS tone would be used on an entire group of radios, the same DCS code is used in a group of radios. CTCSS is used to reduce interference, and to improve spectrum efficiency through channel sharing in commercial networks.

The real name for this method of transmission is Continuous Tone-Coded Squelch System or CTCSS. Most modern FRS and GMRS radios have CTCSS, but most of them don't call it CTCSS. Digital Coded Squelch or DCS is the third type, and it works by adding

Differences between CTCSS and DCS – Retevis. CTCSS & Tone Burst Ham Radio Repeater Access – electronicsnotes CTCSS does not offer any “privacy”, it only filters which transmissions a CB will “un-squelch” for, but everybody in non-CTCSS land can still hear you, whether you want them to or not. CTCSS is a limited aid in sharing channels but the FM capture effect still applies, and the more “powerful” station (either by RF output or proximity) will still win at the end of the day. DCS stands for Digital Coded Squelch and is what you will encounter in the "digital" worldsort of.

However is does have a wide bandwidth from 2 to 300 Hz. Unlike CTCSS (Continuous Tone Coded Squelch System) which uses continuous tones below 300 Hz., DCS uses digital data or code Digital Coded Squelch (DCS) is another application which allows you to ignore (not hear) unwanted calls. It functions the same way as CTCSS. The only differences are the encode/ decode method and the number of selectable codes. For DCS, you can select from 104 different codes. Note: CTCSS/ DCS does not cause your conversation to be private.

However is does have a wide bandwidth from 2 to 300 Hz. Unlike CTCSS (Continuous Tone Coded Squelch System) which uses continuous tones below 300 Hz., DCS uses digital data or code words. DCS is transmitted at a rate of 134.4 bits/s. The DCS waveform directly modulates the FM carrier, with a logic 1 represented by a positive carrier shift and a logic 0 represented by a negative carrier shift. The FM deviation is about the same as CTCSS/PL. CDCSS or Digital Code Squelch (DCS) is a further development of the continuous tone-coded squelch system or CTCSS that uses a slow-speed, binary data stream passed as sub-audible data along with the transmission.
