Voici c'est caractéristique:
The SDR Cube is a totally self-contained, embedded SDR transceiver for CW & SSB using a Softrock for the RF front end and a pc board implementation of an HF modem. A PC is not needed for using the SDR Cube, as all DSP processing is accomplished by an embedded DSP processor on the three internal pc boards. The Cube is designed to fit into an optional 4” x 4” x 4” pre-cut black powder-coated aluminum enclosure containing all controls, a blue graphic display showing the transceiver settings and an exciting 8 kHz-wide band scope of spectrum signals, and the popular Softrock RXTX v6.3 board. The SDR Cube may also be used with any of the 11,000 other Softrocks in the field today! Sold as a kit or as a fully assembled & tested transceiver, the Cube will be available starting in November. We presented on the SDR Cube at TAPR's annual "Digital Communications Conference" in Portland, Oregon, and the DCC Proceedings containing our paper will soon be available from TAPR. Many details are already presented here on this website, and active email discussion occurs in the SDR-Cube Group in Yahoo Groups
- Standalone SDR transceiver ... no PC, portable, compact

- Demonstration Videos -- We have have a number of short videos that overview the features and demonstrate the SDR Cube in action. Hope you find these helpful in seeing the pre-production transceiver in action. The video segments include: Overview, Tuning a CW station (two clips), Tuning SSB stations, CW QSO with YL2QT, and Tuning an RTTY station.
- Online Interview (audio & transcription) -- I was honored to be interviewed by a popular blogger, Tobias Wellnitz, DH1TW, and he has both the audio podcast and a full transcription of the 1 hour 20 minute discussion online! ... http://www.dh1tw.de/sdr-cube-interview. DH1TW is a technically-capable and very enthusiastic ham who regularly publishes podcasts and articles on his website concerning various aspects of amateur radio, contesting, IT and technology in general. He is a great interviewer and I very much enjoyed my discussion with him. We covered a wide range of issues concerning SDR in general, and our new SDR Cube in specific. Hope you enjoy. And thanks very much to DH1TW for providing this useful reporting.
