CTCSS function on walkie-talkies covers a frequency range from 67.0Hz to 250.3Hz. When transmitting in analog sub-tone mode, it transmits by continuously superimposing low-frequency, inaudible signals onto the carrier frequency, ensuring that only receivers receiving the same frequency can interpret the signal. This achieves anti-interference capabilities or allows the receiver to reject signals from other third parties.
