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.

PL (Private Line) is Motorola's trademarked name for this system. General Electric calls theirs CG (Channel Guard). DCS (Digital-Coded Squelch) uses a 23-bit digital pattern to activate coded receivers.

The generic name is CDCSS (Continuous Digital-Coded Squelch System). CTCSS stands for Continuous Tone Coded Squelch System. Basically what it does is this: it adds a tone into your transmission at a certain frequency. Other radios must have the same CTCSS tone or code set to hear the transmission. It will also be heard if the radio has CTCSS and DCS off.

This data is sub-audible with most of it’s energy below 300Hz. 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.

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.

Nu fungerar det iallafall :) vet inte om det är rätt men på PMR kan jag välja Aurora P60 är en systemradio som stödjer: CTCSS, CCIR, ZVEI,.

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.

Some, but not all, repeaters will transmit a CTCSS Tone back. 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.
