Beauty & speed! How to use on GNU+Linux:
1 of 1 found this helpful See the info image. Essentially you install gqrx-sdr which automatically installs gnuradio--an advanced SDR program where you generate software by dragging around flow-charts and what not. I'm using this SDR to experiment with high-speed data transfer via physical SCPA. I've cut the antenna wire and applied it to RAM pins on running laptops, as well as to the SATA data wires of a busy spinning-disk hard drive. And I see beautiful order in chaos. Recording the I/Q data yields raw files which grow ~10MB per second--in "RAW I/Q" mode. That's plenty of processing for a tiny device like this. In this case, I set the frequency to 1.635GHz for maximum contrast & minimum noise. I will provide more details of files produced using this SDR on github: compromise-evident
