The generic name is CDCSS (Continuous Digital-Coded Squelch System). The use of digital squelch on a channel that has existing tone squelch users precludes the use of the 131.8 and 136.5 Hz tones as the digital bit rate is 134.4 bits per second and the decoders set to those two tones will sense an intermittent signal … See more In telecommunications, Continuous Tone-Coded Squelch System or CTCSS is one type of in-band signaling that is used to reduce the annoyance of listening to other users on a shared two-way radio communication … See more CTCSS tones are standardized by the EIA/TIA. The full list of the tones can be found in their original standard RS-220A, and the most recent EIA/TIA-603-E; the CTCSS tones also … See more In non-critical uses, CTCSS can also be used to hide the presence of interfering signals such as receiver-produced intermodulation. Receivers with poor specifications—such as scanners or low-cost mobile radios—cannot reject the strong signals … See more Radio transmitters using CTCSS always transmit their own tone code whenever the transmit button is pressed. The tone is transmitted at a low level simultaneously with the voice. This is called CTCSS encoding. CTCSS tones range from 67 to 257 See more Some professional systems use a phase-reversal of the CTCSS tone at the end of a transmission to eliminate the squelch crash or squelch … See more • Radiotelephony procedure • Signaling (telecommunications) See more

WebFeb 17, 2014 · CTCSS is an acronym for Continuous Tone-Coded Squelch System and is a system that is used in shared two way radio systems. It is common for a single radio channel to be shared over a number of user groups for frequency use efficiency. CTCSS uses a special tone to identify each group of users, and this tone is used to prevent a group …
WebFeb 14, 2012 · CTCSS employs sub-audible tones — which are below the normal 300 Hz to 3,000 Hz voice range of the radio — and uses 67 Hz to 254 Hz tone modulation placed upon the carrier with the voice traffic. These tones are selected from an industry-wide accepted list of tones (see below) and generally are available in your radio’s programming selection. fda ich q6bWebThis need to filter out the other users on a shared frequency gave birth to CTCSS, or Continuous Tone Coded Squelch System.
