Software Defined Radio

SDR's that are interesting to me.

RFSpace

RFspace has a receiver SDR-14 good for 0-30 Mhz. It uses a USB 2.0 interface to the computer and has a Windows program. It's $1099.

He is also working on a software defined spectrum analyzer. 500-30 Mhz.

The software component called SpectraVue is available separately from MOEtronix

WaveCOM

WaveCOM W61PC is a PCI card. $7400 W61LAN includes a computer.

4 inputs, three 50HZ-25MHz and one 52.5 MHz – 87.5 MHz

This system has an onboard DSP

Seems like a closed box when it comes to software. "Source code material is available only to government authorities or official bodies and needs signing of a special license contract."
