SDR-Hub: A New RTL-SDR Scanner and Audio Recorder with Web Interface

Over on GitHub, user shajen has recently released a new open source program called "sdr-hub," which combines his two prior programs, called rtl-sdr-scanner-cpp and sdr-monitor, into one easy-to-launch project. The result is a powerful RTL-SDR scanner and audio recorder, with a web interface. In the past, we posted about rtl-sdr-scanner-cpp when Tech Minds made a video on it.

The scanner feature allows users to scan for active frequencies across a wide spectrum by rapidly retuning the RTL-SDR. If the transmissions are all within the same instantaneous bandwidth, the user can also record the audio.

The web interface then allows users to easily browse any created spectrum graphs and play back any audio recordings.

The software is available as a Docker image, making it easy to install and run.
