DragonOS: Spectrum Detection and Logging with RTL-SDR, ANTSDR and SDR4space.lite

DragonOS is a ready to use Ubuntu Linux image that comes preinstalled with multiple SDR software packages. The creator Aaron also runs a YouTube channel showing how to use the various packages installed. In his latest video Aaron shows how to use the SDR4space.lite application to automatically log the spectrum with an RTL-SDR, as well as with an ANTSDR (PlutoSDR clone).

This video shows how to setup DragonOS Focal to detect spectrum activity with the SDR4space.lite application, RTLSDR, and ANTSDR/PlutoSDR. I then show how to setup both InfluxDB and Grafana, which are both used to accept and log incoming detected frequencies from the SDR4space.lite application and RTLSDR.

InfluxDB is an open-source time series database and Grafana is the open source analytics & monitoring solution. The two solutions combined allow a user to log activity from as many receivers as they'd like and then near time display incoming results in custom dashboards and panels.

This first video goes over the initial setup, to include creating a cron job for repeated frequency detection surveys, how to link the database and visual front end, and then how to create and customize your first dashboard and panel. Information to populate the database comes from two separate receivers in this demonstration, both from a remote RTLSDR connected to a laptop and from an ANTSDR locally connected to the Intel NUC.

Everything needed to get started is either already included in DragonOS Focal or is easily installed as shown in the video. A key part is the included SDR4space.lite application, however, a newer version with updated features is expected soon.
