About the project

SDRangel is an open-source Qt5/OpenGL SDR and signal analyzer frontend supporting many SDR devices such as Airspy, HackRF, LimeSDR, PlutoSDR, RTL-SDR and SDRplay. It lets you receive and transmit radio signals and analyze the spectrum.

Useful for

Receive and decode radio signals from an RTL-SDR or Airspy dongle
Transmit signals with HackRF, LimeSDR or PlutoSDR hardware
Run a headless SDRangel server and control it remotely via SDRangelcli

Why it’s trending

4 stars so far today, about 10 expected by the end of the day. The usual pace is 3 per day, so that's 3.8× as much.
Over the last two days the pace is 4.2× that of the previous week and a half.
The spike has held for 3 days in a row — not a one-off blip.
GitHub Trending C++ today: #1, +17 stars.

Star trust

Growth looks organic: forks and discussion are in line with active projects, and stars arrive unevenly, the way people give them.

These are heuristics, not a verdict: we judge by the repository’s behavior, not by a list of stargazers.
