CTCSS is an analog system. A later Digital-Coded Squelch (DCS) system was developed by Motorola under the trademarked name Digital Private Line (DPL). General Electric responded with the same system under the name of Digital Channel Guard (DCG). Codages CTCSS / DCS. Les principes du codage CTCSS. La majorité des fabricants de PMR/LPD proposent un codage CTCSS (Continuous Tone Coded Squelch System). This video explains the basic technical principles behind CTCSS (continuous tone coded squelch system) and DCS (digitally coded squelch) as well as how they DCS (aka DSQ/DPL) provides a slightly larger range of codes to pick from compared to CTCSS. This means less chance that a nearby station will accidentally overlap with yours.

Transmit tone is taken from the Tone column, receive tone from the ToneSql column. DTCS: DTCS/DCS codes are used. Transmit code is taken from the DTCS Code column, receive code from the DTCS Rx Code column. : Indicates that no method is used for this, either transmit or receive. Built-in CTCSS and DCS Encoder/Decoder Circuits The FT-1900R includes both CTCSS and DCS Encoder/Decoder circuitry, with Reverse CTCSS Decoding also available, to mute your receiver when a particular tone is received (instead of opening your squelch).

Group A can hear all groups because no Lock (incoming door is open).

As you see Group A who turned off CTCSS can hear all Tone: CTCSS tones are used. Transmit tone is taken from the Tone column, receive tone from the ToneSql column. DTCS: DTCS/DCS codes are used.

The device supports CTCSS and DCS codes in normal and invert modes. Strömförsörjning: Replaceable 7.4V / 2800mAh battery, the set 

DCS is a digital form of CTCSS. Instead of sending a continuous audio tone however, it transmits a  Jun 8, 2019 TSQL is Chirp's way of specifying a CTCSS tone mode in BOTH transmit you can actually split CTCSS and DCS tones (digital tones) but that  Sep 13, 2017 known formally as continuous tone-coded squelch system, or CTCSS CTCSS systems were joined by digital coded squelch (DCS) systems  FEATURES. – 15 GMRS Channels. – 8 Repeater Channels.

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. 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.
