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.
