Radio coverage and link planning for amateur radio and beyond. A self-hosted web application written in Go, inspired by Radio Mobile.

• Point-to-point links: terrain profile, path loss, link budget, first Fresnel zone clearance
• Area coverage: link margin raster around a transmitter, rendered on the map
• Propagation: NTIA Irregular Terrain Model (Longley-Rice), ported to Go from the public domain reference; optional tree canopy loss after ITU-R P.833
• Terrain: Copernicus GLO-30 or SRTM tiles from a directory or an S3 bucket
• Runs anywhere: single binary, multi-arch container image, Helm chart

Container images: ghcr.io/radiopath/radiopath

git clone https://github.com/radiopath/radiopath && cd radiopath
make db-up     # PostGIS and Redis via docker compose
make run       # http://localhost:8080

You also need at least one terrain tile, see the README.

AGPL-3.0-or-later. A commercial license is available for running a modified Radiopath as a hosted service without publishing the changes, see COMMERCIAL-LICENSE.md.
