Adds a boolean is_admin column (default false) and has the
registration changeset auto-set it to true when the email matches
graham@mcintire.me (case-insensitive). The migration also backfills
the flag for an existing row with that email.
Users can now register beacon monitors on the settings page. Each
monitor gets a unique random token the remote program will use to
authenticate its reports. Name is the only user-supplied field for
now; more will be added as the monitor protocol is defined.
Also adds :gen_smtp to deps. Swoosh's SMTP adapter depends on
:mimemail which lives in that package, and production was 500'ing
when trying to send confirmation emails without it.
- Register/Log in (or callsign/Settings/Log out) now live next to
the Map/Path/Rover links in the main header instead of a separate
top menu bar
- Add on_mount in UserAuth to assign current_scope on LiveView mount,
and pass current_scope through to Layouts.app from every LiveView
- Drop the old top <ul> from root.html.heex
- Password minimum lowered from 12 to 8 characters
Generated Accounts context, User schema, and controllers via
phx.gen.auth. Adapted it for password-only login with required
email confirmation:
- Users have callsign (unique, uppercased), name, email, password
- Registration form fields: callsign, name, email, password, confirm
- Magic-link login path removed; login is email + password only
- After register, a confirmation email is sent and login is blocked
until the account is confirmed via the token URL
- Confirmation link logs the user in on first use
- SMTP2GO configured as the outgoing mailer in k8s prod
Extract shared Maidenhead grid overlay into maidenhead_grid.js so both
the main map and rover planner use the same implementation. Wire up the
toggle_grid event and checkbox on the rover page matching the main map.
New BandConfig entries for 902, 1296, 2304, 3456, 5760 MHz:
- All beneficial humidity effect (like 10 GHz)
- Near-zero gaseous absorption and rain attenuation
- Ranges: 902 MHz typical 400 km, 5760 MHz typical 220 km
- Same seasonal curves as 10 GHz (ducting-driven)
BandConfig.band_options/0 generates dropdown options from configs.
All pages (path, rover, submit) use centralized band_options instead
of hardcoded lists. Map page already used BandConfig.all_bands().
10 GHz remains the default on all pages.
- Toggle button for Maidenhead grid overlay (on by default)
- Coverage candidates now at 0.25° resolution (~28 km) instead of
2°×1° Maidenhead grids, matching HRRR propagation grid density
- Coverage rectangles render as 0.25° cells for finer detail
- Grid overlay is separate from coverage coloring
- Extract scoring logic to Microwaveprop.Rover.Coverage for testability
- Two-phase computation: fast pass (distance + propagation) for all grids,
then SRTM terrain analysis for top 20 candidates only
- Cap search radius to 300 km to keep candidate count reasonable
- Run terrain analysis in Task with rescue/fallback for resilience
- Background Task doesn't block LiveView process
- 5 tests covering: ranked results, empty inputs, station details,
band range differences, field presence
- Add explicit "Calculate Coverage" button instead of auto-triggering
- Move coverage computation to background Task so LV stays responsive
(users can keep adding/removing stations while it computes)
- Remove all auto-compute triggers from station add/remove/band change
- URL loading resolves stations but doesn't auto-calculate
- Button shows "Finding best roving locations..." spinner while computing
Rewrites rover planner to automatically color the map after stations
are entered. No manual stop selection needed — the system evaluates
every Maidenhead grid in range and scores them by:
- SRTM terrain analysis to each station (diffraction loss, LOS verdict)
- HRRR propagation forecast (ducting, refractivity, atmospheric conditions)
- Distance to stations vs band range limits
- Propagation boost: good conditions (score 80+) make blocked paths
viable through ducting, matching the app's core beyond-LOS prediction
Coverage score formula: boosted path quality 30% + propagation 30%
+ distance 20% + station count 20%. Colored grid squares on the map
show best (green) to worst (red) operating positions.
Sidebar shows top 10 grids ranked with: workable station count,
propagation score, best operating hour, 18-hour forecast sparkline.
Click a grid for per-station detail: distance, terrain verdict,
diffraction loss.
URL stores stations + band for sharing: /rover?stations=W5ISP,K5TR&band=10000
Switch from getCurrentPosition (which looped via push_patch) to
watchPosition with a 60-second throttle. Break the server-side
request_gps loop by skipping re-request when coords already exist.
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
- "My Location" button with text label (was just an icon)
- Two share buttons after results:
- "Copy Link" — fixed coordinates, exact result
- "Copy Link (use viewer's GPS)" — source=gps, dynamic per viewer
- CopyLink JS hook copies full URL to clipboard with "Copied!" feedback
Bookmarking /path?source=gps&destination=K5TR&band=10000 will use
the viewer's device GPS to resolve the source location on load.
The LocateMe hook handles both button clicks and server-pushed
request_gps events. Once coords are resolved, the URL is updated
with actual lat,lon and calculation runs automatically.
- 18-hour propagation forecast bar chart from grid scores at path midpoint
Shows best/worst score and time, color-coded bars
- URL query params: all form fields reflected in URL, auto-calculates
when source+destination present. Bookmarkable/shareable links.
- phx-change on form updates assigns in real-time as user types
- Removed LiveStash in favor of URL-based state persistence
- TX/RX height in feet (converted to meters for terrain analysis)
- TX power in dBm with mW equivalent display
- TX gain and RX gain (dBi) inputs
- Power budget: TX power + TX gain - feed loss = EIRP - path loss
+ RX gain = RX power vs CW sensitivity = margin
- Loss budget: FSPL + gaseous (O2+H2O) + diffraction + rain
with per-km gas rate detail
- GPS "Locate Me" button using browser geolocation API
- Lat,lon coordinate pairs accepted as input
- Weather displayed in F with C below
- LiveStash preserves form inputs across page reloads
- Terrain cross-section with beam line and Fresnel zone
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.
Enqueues ERA5 fetch jobs for contacts where HRRR is unavailable.
Deduplicates by rounded grid point and hour, skips existing profiles.
Usage: mix era5_backfill [limit]
Contact scoring now uses all HRRR profiles along the path instead of
just pos1. Aggregation strategy:
- Best along path for beneficial factors (refractivity, pressure)
- Worst along path for harmful factors (rain, wind)
- Average for neutral factors (temp, dewpoint, PWAT, BL depth)
Scorer.path_integrated_conditions/2 merges multiple profiles into a
single conditions map. Falls back gracefully to single-profile scoring
when only one profile is available.
Apply 5-point circular moving average to reach_km values before
rendering the boundary polygon. Eliminates sharp spikes caused by
isolated terrain anomalies in SRTM data.
Runs BackfillEnqueueWorker every 30 minutes to pick up contacts with
pending/queued/failed enrichment status and enqueue missing jobs.
Before enqueueing, reconciles terrain contacts stuck in "queued" by
checking the terrain_profiles FK directly.
When ASOS/RAOB/IEMRE APIs return empty data, store a stub record so
dedup checks (has_surface_observations?, has_sounding?, has_iemre_observation?)
see coverage and don't recreate the same jobs on future backfill runs.
Queued contacts just need reconciliation (check if data exists),
while pending contacts need actual HRRR fetches. Process pending
first so real work happens before reconciliation.
Backfill dashboard now has checkboxes to select which enrichment types
to process (HRRR, Weather, Terrain, IEMRE). Prevents weather jobs from
flooding the queue when only HRRR needs work.
The propagation grid stores profiles at 0.125° intervals, so contacts
up to 0.0625° from a grid point would miss with the old 0.05° tolerance.
This caused has_hrrr_profile? and find_nearest_hrrr to fail matching
against existing data, leaving contacts incorrectly stuck as pending.
enqueue_for_contact unconditionally marked contacts as :queued even
when no HRRR jobs were needed (profiles already exist). Workers never
updated contact status to :complete after storing profiles. Contacts
got stuck and were never re-processed.
- Mark :complete when no jobs generated (data already exists)
- Include :queued in backfill enrichable states for reconciliation
- Add ecto_psql_extras for PostgreSQL insights in dashboard
- Add os_mon for OS metrics (CPU, memory, disk)
- Fix progress bars using percentage instead of raw large numbers
- libcluster with Kubernetes IP strategy for pod discovery
- RBAC for pod list/get, POD_IP from downward API, shared cookie
- LiveDashboard at /dashboard for all environments
