How it works:

ComTekk 2-Tone 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.

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. This is the sampling rate. 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 300-5,000 Hz. Another filter searches for continuous tones, ingoring noise, voice and digital communications.

The tone frequencies are displayed immediately on screen. 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.
