HackRF device notes - jketterl/openwebrx GitHub Wiki
Driver installation
To make your HackRF available to OpenWebRX, you need to install soapy_connector and soapy_hackrf.
NOTE: These libraries come pre-installed with the OpenWebRX Raspberry Pi images and the Docker images, so if you're running those, you are already good to go.
After the installation, you should be able to see your device using SoapySDRUtil --probe
