Available in February 2004 ~$999.95 The GnuRadio project (http://www.gnu.org/software/gnuradio/) will most certainly support it with free software. WR-G313i Overview The WiNRADiO WR-G313i receiver is a software-defined high-performance HF receiver (9 kHz to 30 MHz, optionally extendable to 180 MHz) on a PCI card. This receiver is intended for government, military, security, surveillance, broadcast monitoring, industrial and demanding consumer applications. The receiver is extremely sensitive, making it possible to comfortably read CW signals under 0.05 µV input levels, yet featuring a very respectable dynamic range making the receiver resistant to strong signal overload. This high sensitivity is also matched by that of the S-meter: The fully calibrated S-meter shows the received signal levels in dBm, µV or S-units, down to ‑140 dBm. The hardware and software package consists of the receiver card, Windows-based software, a start-up antenna and a user's manual. Hardware The PCI card plugs into an available slot of an IBM-compatible PC. Several receivers (as many as there are free PCI slots available) can be controlled by a single PC - an ideal solution for high-performance multi-channel automatic monitoring systems. There is a single SMA antenna connector and an output line audio jack which can be used to connect the receiver output directly to a sound card line-input or an amplified speaker. The receiver has its own on-board DSP, and does not rely on the PC sound card for its performance. As the DSP performs the final stage IF filtering and all demodulation, this receiver is entirely software-defined, which means that additional demodulation or decoding modes can be easily added by a mere software change. No cables or power supplies needed - no clutter on your desk. Every modern desktop computer can be converted into a powerful HF monitoring station with minimum fuss.
