WebOct 24, 2024 · In radio systems with a mix of CTCSS/PL and DCS/DPL usage, it is recommended to avoid using a CTCSS/PL tone of 136.5Hz due to the DCS/DPL kerchunk problem caused by the 134.4Hz DCS reverse burst. The time required to reliably decode DCS is slightly longer than CTCSS and is about 350ms or less. CTCSS typically …
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 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. This is common with General Electric … See more • Radiotelephony procedure • Signaling (telecommunications) 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 may be listed in manufacturers instruction, maintenance or operational … 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
