WebCTCSS/DCS Tones and encryption Many radios on PMR446 utilise tones, the most common two in usage are CTCSS and DCS. CTCSS CTCSS stands for Continuous Tone-Coded Squelch Systems or CTCSS for short. CTCSS is used to allow two or more groups of people to use the same channel as well as covering static noise/interference.
WebDec 20, 2024 · CTCSS is an analog system. A later Digital-Coded Squelch (DCS) system was developed by Motorola under the trademarked name Digital Private Line (DPL). … WebCTCSS tone and DCS code scanning mode can be accessed with or without a signal being present. The scanning process itself only occurs while a signal is being received. Not all repeaters requiring a CTCSS tone or DCS code for access will transmit one back. In that case, the transmitter of a station that can access the repeater would need to be ...
WebCTCSS stands for continuous, tone-coded squelch system, and is a technique used to allow repeaters—and radios—to receive particular signals and reject others. The signals that a … WebThe DCS and CTCSS code function exactly the same as the GMRS radios privacy codes where your radio on channel 14 (the frequency you're transmitting) is using privacy code 7 (the DCS or CTCSS code) will not be able to hear anything but other radios using channel 14 code 7; although other radios with no privacy code set (like your friends again ...
WebAug 15, 2015 · There are two types of tones that you will deal with during your time as an Amateur Radio Operator.
