Features & Specifications
ComTekk 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. Audio recording may be triggered by single or two-tone activation.
- Single and 2-tone decoding
- Standard tone sets
- DTMF decoder
- CTCSS decoder
- DCS decoder (v.1.2) Unfiltered audio or discriminator tap required!
- Audio squelch
- Adjustable trigger delay
- VU meter
- Sound card calibration
- Data Hold & Clear
- Data logging (CSV file)
- Built-in log viewer/player
- Tone-activated audio recording
- Serial port control for external relay (bell, lights, etc.), triggered by any 2-tone or DTMF sequence.
