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. The FM deviation level of DCS data should be in the range of 500 to 800 Hz.Unlike CTCSS, DCS signal spectrum occupies considerable more bandwidth. Let’s talk about CTCSS and DCS today . Specifically, DCS gives you 83 codes, whereas CTCSS gives you somewhere between 26-50 squelch tones depending on the radio -- manufacturers have added extra codes over time. Se hela listan på ailunce.com ciao , i CTCSS e i DCS non sono sottocanali, i canali sono e e basta. I CTCSS sono toni audio di squelch emessi durante la trasmissione , in pratica, consente a due o più corrispondenti radio di comunicare tra loro escludento automaticamente altri segnali radio esterni al loro gruppo; l'apparato trasmittente dotato di CTCSS permette all'utente di impostare uno dei codici CTCSS disponibili ctcss, как и dcs, не является системой шифрования или маскировки радиопередач, поскольку они не затрагивают процесса передачи речи.

DCS (Digital-Coded Squelch) uses a 23-bit digital pattern to activate coded receivers. Digital Coded Squelch (DCS) is somewhat similar, but instead of sending a continuous tone of differing frequency, a Digital data transmission is added to the radio signal. This Digital Code is transmitted at a really low rate, around 134 bits per second (the code is 23 bits long). 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.

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. 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.

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). DCS (aka DSQ/DPL) provides a slightly larger range of codes to pick from compared to CTCSS.

The CTCSS feature also does not offer any security. CTCSS and DCS don’t stop anyone from listening to you, they just stop you from hearing other people. 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. It stands for Digitally Coded Squelch.

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. In that case, you would need to listen on the repeater's input frequency for a station accessing the repeater and identify the tone they are using. ** Due to firmware changes in the UV5R/UV82 over time, this procedure CTCSS and DCS Encode/Decode Built In For easy repeater access, or silent monitoring of busy channels, both CTCSS and DCS (Digital Code Squelch) Encoder/Decoder circuits are built in. CTCSS and DCS configuration data may be stored independently in each memory channel. A “Split Tone” mode also allows operation on systems where CTCSS and DCS CTCSS uses a sub-audible tone transmitted on the signal of the transmitter trying to access the repeater. The amateur radio repeater has a very sharp filter to detect whether the exact tone is present.
