WebSo, even though your radio may be transmitting and receiving on the correct frequencies for a particular repeater, you won’t be able to access the repeater if you’re not also transmitting the CTCSS tone the repeater has … WebApr 14, 2024 · Turned out I could hear him. However, I could not hear a CTCSS tone on his transmission. The repeater in question uses one (I checked in the local listings and on RepeaterBook) so the person talking through the repeater had to be transmitting one. And according to various references, the tones run (approximately) from 67Hz to 250Hz.
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 …

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 data classification sharepoint onlineWebYou 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. dataclass list of objectsbitlocker usb drive not showingWebApr 21, 2006 · Listing 3 shows the heart of the CTCSS tone-detection algorithm, the Analyze () method.
