Tone squelch, or another form of selective calling, is sometimes used to solve interference problems. Where more than one user is on the same channel (co-channel users), selective calling addresses a subset of all receivers. Instead of turning on the receiver audio for any signal, the audio turns on only in the presence of the correct selective calling code. This is akin to the use of a lock on a door. A carrier squelch is unlocked and will let any signal in. Selective calling locks o… WebMar 12, 2024 · Continuously Tone Coded Squelch System (CTCSS) is a sub-audible tone (below 300 Hz) which controls access to radio systems. CTCSS has other names …
WebWhen the CTCSS tone is mixed with the mike audio prior to the deviation limiter stage, an excessive voice signal will be hard limited along with the CTCSS tone, causing a distorted signal. Once the CTCSS tone is distorted past the point where the tone decoder can recover the tone the decoder shuts off and the audio mutes just like it is ...

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 … See more CTCSS tones are standardized by the EIA/TIA.
