Features
Interactive Map Interface
Click to place TX and RX sites. Pan and zoom to any location. Your map position auto-saves.
- Leaflet/Mapbox-based interactive map
- Click to place transmitter and receiver sites
- Auto-generate RX names (RX-1, RX-2, etc.)
- Marker popups show coordinates and signal strength
- Map position and zoom level auto-save
Propagation Modeling (ITU-R P.368-9)
Ground wave predictions for 0.15–30 MHz. International standard, trusted by broadcasters and engineers worldwide.
- LF/MF/HF frequency range (0.15–30 MHz)
- Ground conductivity adjustment (land, sea, urban, rural)
- Antenna height configuration (TX and RX)
- Terrain diffraction via SRTM elevation
- System loss accounting (cables, feedline)
Coverage Heatmap
Visualize signal strength across your region. Color-coded overlay shows coverage at a glance.
- Grid-based computation (0.5 km cells, 25 km radius)
- Adjustable threshold levels (70/60/50/40 dBµV/m)
- Terrain obstacles and diffraction losses included
- Real-time updates as you change parameters
- Export heatmap to Google Earth (KMZ)
Elevation Data Integration
Accurate terrain modeling for realistic predictions. SRTM preferred; OpenTopography API fallback.
- SRTM (Shuttle Radar Topography) — 90 m resolution, most of world
- OpenTopography API fallback if SRTM unavailable
- Local tile caching for fast re-computation
- Diffraction losses from terrain obstacles
- Fresnel zone clearance analysis
