The decoder is watching for the correct tones and the correct tone timing so it treats both the first audio page and the second audio page as completely different events. Listen to an actual page. 378.6 Hz / 422.1 Hz with a 1 second / 3 second timing.
Download toneDetect for free. A sequential tone decoder geared towards the type of paging used by Fire/EMS. It is written in Python for portability and has been tested on Windows, Linux and Mac.
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.
The lab experience is based on the integrated PLL tone decoder type NE567 or LMC567. Design the circuit to get a detection range centred on 20 kHz, with bandwidth 10% around the central frequency (maximum bandwidth for this device). Supply voltage: 5 V The tone.

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.
