Channel Number Frequency (MHz) 0 199.5 1 67.0 2 71.9 DCS (Digital Coded Squelch) is digital data or code word that is transmitted with the voice audio. 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.

These two systems are also referred to by other names, including CDCSS, PL and DPL, but the official terms are CTCSS and DCS. They both have the same function and work in similar ways. CTCSS stands for Continuous Tone Coded Squelch System. DCS (Digital Coded Squelch) is digital data or code word that is transmitted with the voice audio. This data is sub-audible with most of it's energy below 300Hz.

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.

In CHIRP it is called Tone for transmit Both CTCSS and DCS were designed to ignore other users on a radio frequency Think of them as electronic ear plugs CTCSS is analog (a selection of tones, generally between 67 Hz and 255 Hz) DCS is digital (one 134.4 Hz tone carrying 23 bits of data) Most of the time, we only think in terms of transmitting tones DCS DCS (Digital Coded Squelch) is digital data or code word that is transmitted with the voice audio. 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 words. CTCSS is part of a repeater's receiver that allows only signals with the proper "Tone" to access or open the receiver. This allows distant repeaters using a different CTCSS to co-exist on the same frequency. Some, but not all, repeaters will transmit a CTCSS Tone back.
