• Feed scanner or receiver audio directly into computer sound card, or simply place computer microphone close to receiver's speaker.
• Built-in Auto-Calibration system for high accuracy.
• Smart filtering ignores voice audio, noise and data / ANI signals.
• Useful for programming scanners such as the Uniden BCD396T  with a "Fire station tone-out" feature. Read the review on RadioReference.com

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.
