DragonOS: Now with RF Propagation and Calculation Tool

DragonOS is a ready to use Ubuntu Linux image that comes preinstalled with multiple SDR software packages. In the recent R14 Preview update, Aaron, the creator of DragonOS has added a new very useful RF propagation and calculation tool. The tool works in conjunction with elevation data to calculate the theoretical signal propagation of a transmitter.

The tool is provided by the open source Signal Server software package, which is based on the original SPLAT! software by John Magliacane (KD2BD). Aaron has also provided a video that demonstrates the software in action, shows how to use it, and explains his future plans for making it easier to use.

This video is a preview of a new RF Propagation and Calculation feature provided by Signal Server. Additionally, custom web server scripts by Dr. Bill Walker, will also be included in DragonOS Focal R14 in the near future. There's a lot of moving parts, but once complete, all you "should" have to do is download, convert, and place the SRTM elevation data for the areas needing coverage calculations in the /usr/src/SDF directory. In the meantime, I'd recommend reading up on all the below material. I've been reading a lot and still don't understand it all!

      A couple additional tools are taking some time to work out, but tomorrow I’ll go ahead make another short “how to” video and upload what’s currently available and working to a temporary Google drive with link. Just know it’ll be replaced with a new ISO once everything is compete. RF propagation and modeling is working, can be exported to KMZ, and for the time being opened in Google Earth.
