https://stream.echo6.co/videos/watch/af71b790-c27e-4110-8cd9-444043307fd0 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! What is Signal Server? Signal Server is a multi-threaded RF coverage calculator based on Splat! https://github.com/N9OZB/Signal-Server What is SPLAT!? SPLAT! is an RF Signal Propagation, Loss, And Terrain analysis tool for the electromagnetic spectrum between 20 MHz and 20 GHz. https://www.qsl.net/kd2bd/splat.html What is SRTM data? https://en.wikipedia.org/wiki/Shuttle_Radar_Topography_Mission One place to get SRTM data from http://www.viewfinderpanoramas.org Big Thanks to Dr. Bill Walker for sharing his work, helping understand how SPLAT! and Signal Server works, and for taking the time to update the SPLAT! Web-server to the faster multi threaded Signal Server application.
