DragonOS: Automated Spectrum Analysis with SDR4Space.lite

Over on YouTube Aaron has uploaded a video showing how he is using the SDR4Space.lite package in DragonOS to do some interesting experiments with automated spectrum analysis using a PlutoSDR or RTL-SDR. As a reminder, Aaron is responsible for DragonOS which is a Linux OS with many SDR software programs preinstalled (including SDR4Space.lite).

This video shows how to use the RTLSDR/PlutoSDR with some of the prebuilt SDR4space.lite javascript examples preinstalled in DragonOS Focal.

I start out showing the new IQ recording script w/both the RTLSDR or the PlutoSDR. After a recording is triggered, the saved file can be looked at with inspectrum, SigDigger, etc. The javascript itself can be modified to produce desired results, but by default it's setup to record POCSAG.

The second half of the video shows how to use the wide spectrum analysis javascript to look at 88-108Mhz. The script produces a graphical representation of the RF spectrum along with a spreadsheet containing the corresponding RF information.

Any of these scripts can be modified, new ones can be built, and cron jobs or other scripts could call upon them as needed. I hope to do more videos once I figure out how to take the data and put it into some sort of database.
