A radio with CTCSS enabled will only pass audio for the tone it has set. DCS works the same, apart from it being digital instead. It stands for Digitally Coded Squelch. It sends a number repeatedly encoded in digital as you speak, in the low frequencies so you do not hear it. If someone else transmits on the channel with a different or no DCS, the radio will not unmute.

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). The generic name is CDCSS (Continuous Digital-Coded Squelch System). The audio is normally applied after the frequency limiting microphone circuitry, usually at the wiper of the deviation ("modulation") control. As such, CTCSS can be used with PM transmitters as well as true FM transmitters. DCS / DPL is normally applied to the r.f.

DCS. Digital Coded Squelch (DCS) is a newer signaling system that now comes standard on most amateur FM transceivers. Although it operates differently, it can be roughly thought of as a digital form of CTCSS. Instead of sending a continuous low frequency sine wave, DCS sends a 134.4 bits per second digital signal on the transmit signal.

If someone has a radio with no CTCSS and DCS on, they will be able to hear everyone on the channel, including people using CTCSS and DCS. A radio with CTCSS enabled will only pass audio for the tone it has set. DCS works the same, apart from it being digital instead.

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

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 a sub-audible digital bitstream to the transmitted audio. The bitstream is used to transmit a code along with the audio. CTCSS (Continuous Tone-Coded Squelch System) uses sub-audible (below 300 Hz, not necessarily inaudible) tones to activate coded receivers.

transmit either CTCSS or DCS signals subaudibly along with the voice information. U.S. military field radios employ wider deviation and a 150 Hz CTCSS tone, not supported by most scanners or CTCSS decoders. There are over 40 different CTCSS codes and you can program a specific CTCSS or DCS code into each memory channel. CTCSS for Dummys; Great article! I remember back in the 90's my local repeater had a tone on the output, but also passed through a tone from the input.

CTCSS.

This can be the case where there are a number of repeaters at the same site and 2019-2-25 · The Continuous Tone Coded Squelch System, commonly referred to as CTCSS, has been in used in the land mobile radio arena from the late 1960’s.It is known by a number of different trade names such as Private Line® (PL) by Motorola, Channel Guard® (CG) by General Electric and generically as tone squelch.. It is a use of sub-audible tones that are transmitted along with the speech portion of 2020-11-8 · How and Why We Use CTCSS (PL) in Amateur Radio The “standard” tones.

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.

And you can encode CTCSS and decode DCS, or vice versa, too, if your application requires it. Scanning for CTCSS and DCS Tones/Codes * Not all repeaters requiring a CTCSS tone or DCS code for access will transmit one back.
