Opening the Window to Digital Radio Communications
The Digital Suite expands the power of your WiNRADiO receiver with numerous digital processing facilities, including:
* WEFAX (Satellite Weather Fax) * HF Fax *Packet Radio * Aircraft Addressing & Reporting System (ACARS) *Digital Tone Multi-Frequency Signaling (DTMF) *Continuous Tone Coded Squelch System (CTCSS) *Signal Classifier *Audio Oscilloscope and Spectrum Analyzer *Squelch-controlled Audio Recorder and Playback
Upon installation, the Digital Suite will appear as a new menu entry in the WiNRADiO receiver software, and all the above modules can be invoked from there.
Fax Module - The facsimile module enables the reception of orbiting weather satellites and HF fax. Received images are decoded and displayed in real time. Sophisticated decoding and image processing methods are used to display received images with maximum clarity.
Packet Radio - This version of AX.25 standard packet radio decoder implements protocol monitoring of two most common modulation techniques used in the amateur radio packet network: 1200 Baud FM AFSK (used above 30MHz) and 300 Baud FSK, common on amateur HF bands.
Aircraft Addressing and Reporting System (ACARS) - ACARS is an air/ground network which enables aircraft to function as mobile computer terminals, with links to control stations. Although most airliners use this system, only parts of the transmission protocol are standardized or publicly accessible. This implementation of the ACARS decoder allows decoding of common types of messages, while leaving unrecognized parts in plain text form (as received).
DTMF - In radio communications, the Dual Tone Multi-Frequency coding is used in various signaling systems, while radio amateurs utilize this system to control repeaters and other remotely-controlled devices. This implementation of a DTMF decoder contains a logging facility, which allows later inspection of received codes together with time/date information.
CTCSS - CTCSS (Continuous Tone Coded Squelch System, sometimes referred to as PL or Private Line) decoder is useful for monitoring of communication channels with sub-audible tone signaling. This is particularly suitable for scanning purposes, where a particular user, or a desired group of users, can selectively monitored. This decoder also implements recording of transmissions with a specified subcarrier into Windows standard ".wav" files.
Signal Classifier - This module makes it possible to distinguish different types of signals commonly encountered while scanning. By selecting only the desired signal types, scanning can be speeded up quite substantially. The following classification categories are implemented: voice, data, noise or silent channel (unmodulated carrier).
Audio Oscilloscope - This module presents a fully-fledged storage oscilloscope with a scrollable Waveform Grabber. This tool is available for analysis of audio signals from DC to 20kHz, with dynamic range given by the quality of the sound card (usually better than 80 dB).
Audio Spectrum Analyzer - The Audio Spectrum Analyzer uses an advanced FFT algorithm together with optimized CPU machine coding, which allows real time spectrum analysis with a brilliant responsiveness. A user definable set of markers makes it possible to determine frequencies with resolution of a few Hz.
Squelch Controlled Recorder - The WiNRADiO Digital Suite makes it possible to record and playback the received signal, using Windows standard ".wav" files. Recording can be turned on and off automatically depending on the received signal level - this is controlled by the squelch setting of the WiNRADiO receiver.
