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 channel. It is sometimes referred to as tone squelch. It does this by adding a low frequency … 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 See more In non-critical uses, CTCSS can also be used to hide the presence of interfering signals such as receiver-produced intermodulation. … 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 … 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 tail.
