What's the motivator for EE's backing? Assuming it's not just a random crowdfunding campaign they were feeling charitable to. Do they want their own SDR to e.g. do network/ frequency analysis? Or advanced radio R&D?

This is new kid on the block of Software Defined Radio. More to be read about technology: http://rtlsdr.org/ http://rtlsdr.org/ One of the SDR portals: http://www.rtl-sdr.com/ http://www.rtl-sdr.com/ You can buy cheapest SDR for 20USD these days. Great to play, and there is even a marvelous GNU Radio available (http://gnuradio.org/ http://gnuradio.org/) - Yikes :)

  Where can I get a $20 SDR?
  - methurston 10y ago
    The rtl-sdr dongle is available for around $25 on Amazon.

      $8.66, and I'm sure you can go lower. https://www.amazon.com/DVB-T-RTL2832U-RTL-SDR-Receiver-Compatible/dp/B00PDM76ZW https://www.amazon.com/DVB-T-RTL2832U-RTL-SDR-Receiver-Compa... Anything with RTL2832U + R820T will do.

    Here's a page with radios that work for sure: http://www.rtl-sdr.com/buy-rtl-sdr-dvb-t-dongles/ http://www.rtl-sdr.com/buy-rtl-sdr-dvb-t-dongles/ By the way, these are receivers. If you want to transmit using SDR, the hardware is going to be a bit more expensive.
