Frequency (MHz) 2020-4-27 · Incidentally, there is/was a digital variation of CTCSS developed much later called Digital Controlled Squelch (DCS). Relatively rare, the 83 or 104 ‘tones’ or ‘codes’ that system used were digitally generated using 23-bit group addresses or ‘codewords’ using FSK FM carrier modulation. 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 = Continuous Tone-Coded Squelch System CTCSS brand names: Private-Line (PL), Channel Guard (CG), Quiet Tone (QT) DPL = Motorola Digital Private Line (DPL). Motorola trademarked the DPL name, so other radio manufacturers have to call it something different. Digital Coded Squelch (DCS) appears to be the generic name.

If it does, your radio needs to transmit the matching KEY to enter. 2018-1-9 2016-8-26 2007-11-28 · CTCSS (Continuous Tone-Coded Squelch System) uses sub-audible (below 300 Hz, not necessarily inaudible) tones to activate coded receivers. PL (Private Line) is Motorola's trademarked name for this system. General Electric calls theirs CG (Channel Guard). DCS … CTCSS and DCS. Continuous Tone-Coded Squelch System (CTCSS) CTCSS is a sub-audible tone that can be added to a frequency to help reduce interference from other users of the frequency. In most cases it is used to eliminate interference getting into a repeater system.

It seems they originally intended to create a dPMR based radio standard called NDR, using their own vocoder. dPMR radios with this vocoder could be sold CTCSS codes are functions that reject undesired signals on your channel. You will hear a call only when you receive a signal that contains a matching CTCSS tone or DCS code. If a call containing a different tone or code is received, squelch will not open and you will not hear the call. transmit either CTCSS or DCS signals subaudibly along with the voice information.

In   Jul 20, 2020 Both CTCSS and DCS were designed to ignore other users on a radio frequency.

A poor low frequency response in the transmitter or receiver may not seriously distort a single frequency (tone) signal but may seriously degrade a wide band signal … 2020-9-3 2021-4-9 · According to one commenter on this article, the DRA is a Chinese entity but seems not to have produced anything since 2010. I did some further research (originally for this article) and found out that DRA stands for Digital Radio Association.
