Finally got around to introducing what I've been working on for the past couple of years (for those who haven't heard about it already). Full post: http://kpreid.livejournal.com/52312.htmlShinySDR
(why yes, I am terrible at naming things) is a software-defined radio receiver application.
Specifically, it is in the same space as Gqrx, SDR#, HDSDR, etc.: a program which runs on your computer (as opposed to embedded in a standalone radio) and uses a peripheral device (rtl-sdr, HackRF, USRP, etc.) for the RF interface. Given such a device, it can be used to listen to or otherwise decode a variety of radio transmissions (including the AM and FM broadcast bands everyone knows, but also shortwave, amateur radio, two-way radios, certain kinds of telemetry including aircraft positions, and more as I get around to it).
ShinySDR is basically my “I want my own one of these” project (the UI still shows signs of “I’ll just do what Gqrx did for now”), but it does have some unique features. Have a look at the README on GitHub for details: https://github.com/kpreid/shinysdr
