Drops the formal "What we're trying to do / The approach / The stack"
scaffolding for a shorter, first-person telling: line-of-sight is
wrong, here's what we're doing about it, here's what's in the box,
here's what's next. Adds a highlighted note that the scoring is
hand-calibrated and not updated in real time, with links to the
algorithm page and the submit page so readers can help close the
loop.
Contacts now carry a user_id FK to users. When a logged-in user
submits a contact (single or CSV upload), the server injects their
user_id and the email from their account into the submission params,
and the visible email input is replaced with a hidden input holding
that value — logged-in users don't have to retype their address.
The submission changeset now requires at least one of user_id or
submitter_email (rather than hard-requiring email), and email format
is only validated when one is actually present.
Reworded the submit-page blurb from "10 GHz to 241 GHz" to "902 MHz
and up" so it matches the actual band coverage of the project.
Per-point ERA5 fetches were tragically slow because every point-hour
triggered its own asynchronous CDS job (submit → poll → assemble →
download). For backfill this meant thousands of independent jobs
queued against Copernicus. The new path groups requests by calendar
month and a 2° × 2° lat/lon tile so one CDS cycle populates ~60k
profiles at once, and Oban uniqueness on (year, month, tile_lat,
tile_lon) collapses every duplicate enqueue.
- Era5BatchClient builds the monthly CDS requests, extracts every
(lat, lon, hour) from the GRIB2 blob with wgrib2, derives
refractivity params, and bulk-inserts in 2k-row chunks with
on_conflict: :nothing. fetch_month_into_db/1 short-circuits when
the month-tile already has any cached profile.
- Era5MonthBatchWorker runs the batch on the :era5 queue with a
generous backoff (10m → 1d) and the uniqueness key above.
- Era5FetchWorker is now a thin router: cache hit → :ok, cache miss
→ enqueue the month-batch for the point's tile-month and return.
No more per-point CDS calls.
- Wgrib2 grows extract_grid_messages/3 which preserves per-message
datetimes by parsing `d=YYYYMMDDHH[MMSS]` from the inventory, so a
single GRIB2 file carrying a whole month decodes correctly.
- The era5_backfill mix task enqueues month-tile batches directly.
Uploads now show a review page with three summary cards (valid,
duplicates, invalid), tables for invalid and duplicate rows, and a
sample of the first 20 valid rows. Nothing is written to the database
until the user clicks "Looks good — submit N contacts".
Duplicate detection treats two rows as the same contact if they share
the same pair of (callsign, grid) tuples (direction-agnostic), the
same band, and timestamps within 60 minutes. Dedup runs against both
existing DB contacts (single band/time-scoped query) and earlier rows
in the same upload, and the preview labels which side matched.
CsvImport grows preview/2 + commit/1; the old import/2 is kept as a
thin backward-compat wrapper that skips dedup. Added 11 new CsvImport
tests and reworked the SubmitLive CSV tests for the two-step flow.
Pruning used to only run at the end of a successful PropagationGridWorker
pass, so a stretch of failed compute jobs (k8s OOM kills, SIGTERM)
stopped prune from running and let the table accumulate ~5h of stale
rows. A dedicated PropagationPruneWorker now runs every 15 minutes on
its own Oban cron, and PropagationGridWorker also calls prune_old_scores
at the start of each run as a second safety net. Bumped the delete
timeout from 2m to 5m so the first catch-up pass has enough headroom.
New PrivacyLive page explains that collected/submitted data is used
only for propagation research and will never be sold, traded, or
disclosed. Layouts.app now renders a small footer with the NTMS
attribution and a Privacy link on every page that uses it, so the
full-screen map pages are untouched. The duplicate NTMS credit on
the About page is removed since it now lives in the shared footer.
OSM's tile usage policy requires a Referer header identifying the site.
strict-origin-when-cross-origin is the current browser default and sends
the origin on HTTPS→HTTPS cross-origin requests; pinning it explicitly
prevents silently losing the header if a browser default ever changes.
- Beacon map defaults to just the marker at zoom 11. A daisyUI toggle
switch shows/hides the estimated-coverage cell layer; the coverage
info line and tier legend are hidden unless the toggle is on.
- Beacon detail list replaced with a compact dl grid (2-4 columns).
Lat/lon rounded to 5 decimals, power/height/beamwidth formatted via
Beacon.format_mw/1 so no more "2.5e3" scientific notation or "280.0".
format_mw/1 hoisted onto the schema so index and show share it.
- About page no longer uses prose classes (this project doesn't load
@tailwindcss/typography). Headings, lists, and paragraphs now use
explicit utility classes so they render as intended.
Beacons can now record a directional bearing ("omni" or 0-360 degrees)
and a beamwidth in degrees. The keying list grows from {on_off, fsk}
to include FM Voice, WSPR, and the full Q65A/B/C/D/E × 15/30/60/120
family, grouped via optgroups in the submission form.
- /map now centers on the visitor's Cloudflare geolocation when the
cf-iplatitude/cf-iplongitude headers are present, falling back to DFW.
Initial HRRR score bounds track the chosen center.
- Added /about link to the /map side navigation.
- Renamed "Propagation Map" label to "Propagation Prediction Map" in
the /map page title, sidebars, and the /weather back-link.
- Populated /about with mission, approach, stack, roadmap, and a live
stat grid fed from DB counts (estimates via pg_class.reltuples for
the multi-million-row tables).
- Anonymous users can submit beacons (held pending admin approval)
- Added notes field to beacons (textarea on form, shown on detail page)
- Added Beacons link to /map sidebar nav (mobile + desktop),
removed stale Rover Planner link
- Moved /backfill to /admin/backfill under the admin live_session
- Beacon detail map zooms in two extra levels after fitBounds
The Era5FetchWorker now declares an Oban unique constraint on
{lat, lon, valid_time} for any job in available/scheduled/executing/
retryable, so two backfill runs targeting the same contact grid point
can no longer spawn parallel CDS requests for the same hour.
Because Oban OSS insert_all doesn't honor unique, ERA5 jobs are now
routed through Oban.insert/1 from ContactWeatherEnqueueWorker and the
era5_backfill mix task. Other worker types still use insert_all.
Non-admin users can now submit beacons but they are held in an
unapproved state until an admin approves them. Only approved beacons
appear in the public list; pending submissions are shown in a separate
admin-only section on /beacons with Approve and Delete actions. The
show page surfaces a pending badge and an admin-only Approve button
when viewing an unapproved beacon.
Also formats EIRP (mW) on the index page without scientific notation.
Replace the idealised concentric-circle range rings with a realistic
per-HRRR-grid-cell reception map. For every 0.125° grid point within
the band's exceptional range, the estimator computes great-circle
distance, FSPL + atmospheric loss, and applies a cell-specific score
adjustment of (50 - score) * 0.3 dB — score 100 gives a 15 dB ducting
boost, score 0 a 15 dB penalty. Cells below the -145 dBm detection
floor are dropped.
The beacon map hook now renders each surviving cell as a 0.125°
filled rectangle with a tooltip showing tier, Rx dBm, distance, and
HRRR score, so the coverage footprint bulges where ducting conditions
are good and cuts off where they aren't, instead of being a perfect
circle. Falls back to score 50 for cells that don't have HRRR data
yet, so the plot is always useful.
Also fixes the prior all-grey-tiles regression by restoring an
explicit setView() at map creation and adding a post-mount
invalidateSize() for when the map is placed inside a flex container.
The power_mw field represents the beacon's effective radiated power,
not just transmitter output. Relabel it as "TX power (EIRP)" on the
form and detail list, "EIRP (mW)" in the index, and drop the now-
meaningless tx_gain_dbi constant in RangeEstimate since the stored
value already includes antenna gain.
- Add on_the_air boolean to beacons (default true); surfaced as a
checkbox on the form, a badge on the index, and in the detail list.
- Render a Leaflet map on the beacon show page with a marker at the
beacon's lat/lon tooltipped with callsign + frequency. Marker is
green when on air, gray when off.
- Compute and draw a reception-range estimate as concentric signal-
strength rings. New Microwaveprop.Beacons.RangeEstimate solves a
link budget (FSPL + O2/H2O absorption from BandConfig) at five RX
thresholds (-100 to -145 dBm), then scales by 0.5 + score/100 from
the latest Propagation.point_detail at the beacon's grid square, so
current HRRR conditions shift the rings in or out.
- Re-enable the hourly PropagationGridWorker cron and freshness
monitor in dev.exs so dev actually has HRRR-backed scores to feed
the new estimator.
- Rename beacons.height_m to height_ft; migration converts existing
values (m * 3.28084). Form/list/show labels updated.
- Beacon changeset now fills lat/lon from the grid when they're blank
(previously only the reverse worked). Lat/lon and grid inputs are no
longer marked required in the form — enter one side and the other
populates on blur via phx-change.
- Rename beacons.power_watts to power_mw (migration multiplies existing
values by 1000); form/list/show all relabeled to "Power (mW)"
- Fix Add-monitor button alignment on /users/settings by rendering the
label above and putting the input and button in a plain flex row so
the input wrapper margin no longer offsets the button
- Extend the settings page re-auth window from 10 minutes to 24 hours
- Move controls (band selector, grid toggle, nav links) to a docked
right sidebar on desktop, keep floating overlay on mobile
- Point detail panel floats over the map bottom-left instead of inside
the narrow sidebar
- Add collapse/expand toggle for the sidebar
- Add auth links (login/logout/settings) to sidebar
- Wrap public live routes in live_session with UserAuth on_mount
- Use daisyUI menu lists for sidebar navigation

Beacons:
- Scaffolded with phx.gen.live then reworked so reads are public
and mutations go through a live_session gated by the new
:require_admin on_mount hook in UserAuth
- Beacon schema stores frequency (MHz), callsign, grid, lat/lon,
power (W), and height above ground (m); grid auto-derives from
lat/lon when left blank via Maidenhead.from_latlon
- Adds Maidenhead.from_latlon/3 so we can compute grids locally
instead of hitting an external API
Users admin page:
- /users and /users/:id/edit (admin-only) for listing, editing
(callsign/name/email/is_admin), and deleting other users
- Adds Accounts.list_users, admin_update_user, delete_user, and
a dedicated admin_changeset on the User schema
- Nav gains a "Users" link for admins and a "Beacons" link for
everyone
