Serial port control for external relay (bell, lights, etc.), triggered by any 2-tone or DTMF sequence.įor detailed operating instructions, proceed to Using Multi Decoder.Audio recording may be triggered by single or two-tone activation. Now, simply enter the two frequencies into a two-tone alert radio such as the Uniden BCD396T to be alerted any time that tone-out is sent.ĬTCSS, DTMF and any single or dual sequential (1+1) tone format such asĬomTekk 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.ĬomTekk Multi Decoder will listen for any sustained tone signal and display the frequency or frequencies. The tone frequencies are displayed immediately on screen. DTMF tones, most commonly known as "Touch-Tone" (tm AT&T) are used for paging, ANI and remote control over radio, and for dialing on telephone lines. Frequencies below 250 Hz are generally reserved for CTCSS sub-audible tones used to access repeaters and limit interference. Another filter searches for continuous tones, ingoring noise, voice and digital communications. With time and magnitude data, the software first processes each batch of samples by applying a band-pass filter or window, thereby ignoring any frequencies outside the range of 250-5,000 Hz. Receiver audio output is fed into the computer's sound card (via cable or microphone) where an A/D converter reads the signal's instantaneous voltage 11,025 times per second. Read on for complete description.OR see the online User ManualĬomTekk Multi-Decoder utilizes the latest in Digital Signal Processing (DSP) technology to instantly and accurately measure the frequencies of a received two-tone paging signal or "fire dispatch tone out" signal, CTCSS "PL" tones, and DTMF codes. by adding an external relay (we hope to providing this accessory soon).
