Features & Specifications
1. Features & Tools
ComTekk is a unique, versatile software product designed for radio service, testing, simulation and engineering. Most common audio signaling formats can be produced, with the exception of FSK/AFSK modes, some of which are proprietary and must be licensed.
Utilizing the computer's default sound device, different types of signals may be produced simultaneously, with separate level controls for each generator. A common example would be simulation of a tone-remote console, with CTCSS and 2-tone page signals.
The following tools are available, depending upon version and purchased options:
- Tone generator
- CTCSS Encoder
- Gaussian (white) Noise Generator (V1.2 or later)
- DTMF Encoder
- *Tone paging, All single and 2-tone formats or custom
- *5/6-tone ANI or selective calling / paging
- *Tone remote control (single or dual tone)
- Auto-Calibration (V1.06 or later)
- WAV file recording
- PTT relay activation (compatible with ComTekk Universal Radio Interface)
- Audio Oscilloscope
- Audio Spectrum Analyzer
- *8-bit, 8Kbps recording (special order)
* = Optional features
ComTekk utilizes the computer system's default audio device.
