Interactive map-based tool for planning rover operating positions.
Rovers enter stationary stations they want to work, then click the
map to evaluate candidate operating grids.
Features:
- Add stationary stations by callsign or grid square
- Click map to add operating positions (snaps to Maidenhead grid)
- Async SRTM terrain analysis: each stop computes terrain profile
to every station, shows CLEAR/BLOCKED verdict + diffraction loss
- Terrain lines on map: green=workable, red=blocked, dashed=marginal
- Propagation score and 18-hour forecast sparkline per stop
- Route summary: driving distance, unique grid-station pairs
- Band selector affects range limits and propagation scores
- Numbered waypoint markers with score-colored backgrounds
New files:
- Geo module (shared haversine/bearing, used by PathLive too)
- RoverLive with fullscreen map + sidebar
- RoverMap JS hook with grid overlay, station/stop markers, route line
- Nav links in header and map control panel
LiveView page for analyzing microwave propagation between two points.
Features:
- Source/destination input: callsign (via gridmap.org API) or Maidenhead grid
- Band selector for all 8 microwave bands (10-241 GHz)
- Leaflet map showing path line (reuses ContactMap hook)
- Terrain elevation cross-section (reuses ElevationProfile hook)
- Link summary: distance, bearing, terrain verdict
- Loss budget: FSPL + O2 + H2O + rain + diffraction
- Propagation score with 10-factor breakdown
- Current atmospheric conditions from path-integrated HRRR
New CallsignClient for gridmap.org location lookup.
Navigation links added to main navbar and map control panel.
- Leaflet map on contact detail pages showing both station locations
- SRTM elevation profile with Chart.js: terrain, LOS, Fresnel zone
- Path info: distance, azimuth, elevation angle in both directions
- Compact 4-column grid layout for contact details
- Contact map page with all contacts plotted
- Rename QSOs to Contacts in page header
- Wrap algo page in standard layout
- All menus and UI text now say Contacts instead of QSOs
- Add 68, 122, 134, 241 GHz bands to submit form and validation
- Add info box on submit page explaining why contacts matter
- Larger submit button with icon
- Make HRRR partition migration idempotent for partial re-runs
ML Integration:
- Load trained model at app startup, cache compiled predict fn in persistent_term
- Grid worker uses batched ML prediction (10K chunks) when model loaded,
falls back to algorithm scorer when not
- ML score replaces composite, algorithm factor scores preserved for detail view
- Fix process explosion: single EXLA call per chunk instead of per-grid-point
QSO Features:
- Callsign search (ILIKE on station1/station2) with trigram indexes
- Reciprocal QSO grouping (same pair, same band, same hour)
- Wider layout (max-w-7xl) for data table pages
- QSO Training Data link on map page
Infrastructure:
- Re-enable hourly propagation grid worker in dev
- Track ML model weights in git for Docker builds
- Add btree indexes on qsos (timestamp, band, distance_km)
- Remove nav icons from layout header
- Document Finding 11: regional QSO performance by Maidenhead field
- Explain why regional weight adjustments are not justified
- Fix algo.md table formatting (blank lines before tables for Earmark)
- Change page title from Phoenix Framework to North Texas Microwave Society
Vendor Leaflet 1.9.4 (JS, CSS, marker images) and wire it into
the esbuild/Tailwind asset pipeline. Create MapLive with band
selector buttons, auto-refresh, and a colocated JS hook that
renders propagation scores as color-coded circle markers with a
legend. Stub Propagation context and BandConfig modules provide
the data interface for the scoring pipeline.
Add nav bar with links to Map, QSOs, and Submit pages.
