WebFeb 14, 2012 · CTCSS employs sub-audible tones — which are below the normal 300 Hz to 3,000 Hz voice range of the radio — and uses 67 Hz to 254 Hz tone modulation placed upon the carrier with the voice traffic. These tones are selected from an industry-wide accepted list of tones (see below) and generally are available in your radio’s programming selection. WebSep 17, 2024 · CTCSS is an analog system.

BR330T - how to find CTCSS or DCS Tone/code?
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 … WebYou may be able to trick the CTCSS-only radio into receiving transmissions from the DTCS-only radio by selecting a CTCSS tone of 134.4 Hz while sending a DTCS of, shoot, anything I guess; the important thing is that no matter what digital code the DTCS radio is sending, DTCS is sent at 134.4 bps, and those bits might just pulse as a 134.4 Hz tone.
