WebComTekk Multi Decoder makes use of the computer sound card and software DSP (Digital Signal Processing) techniques to decode and instantly display paging, DTMF, and CTCSS tone-encoded information. ComTekk Multi Decoder will listen for any sustained tone signal and display the frequency or frequencies. 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 tones range from 67 to 257 Hz. The tones are usually referred to as sub-audible tones. In an FM two-way radio system, CTCSS encoder levels are usually set for 15% of system deviation. For example, in a 5 kHz deviation system, the CTCSS tone level woul… flu season deaths statisticshttp://scomcontrollers.com/7330 flu season background
