- Add belongs_to :user on Beacon schema, preload in get_beacon!/1
- Show "Submitted by {callsign}" on beacon detail page
- Add NTMS donation link on the about page
- Change grid preference text to 8 characters (e.g. EM12kp37)
Parse ADIF tagged-data format with fuzzy frequency-to-band matching
(nearest microwave band for any freq >= 900 MHz). Supports STATION_CALLSIGN,
OPERATOR, CALL, GRIDSQUARE, MY_GRIDSQUARE, FREQ, BAND, QSO_DATE, TIME_ON.
Same dedup and preview/commit flow as CSV upload.
Also fix select dropdown text alignment in daisyUI.
Backfill page now sums child partition stats for partitioned tables
like hrrr_profiles (relkind 'p') which were excluded by the relkind
'r' filter. Contacts map defers Leaflet init to requestAnimationFrame
so the flex container has dimensions before map initialization.
Replace the JS-built Leaflet control panel with a server-side
sidebar (desktop) and mobile floating controls. Band checkboxes,
callsign filter, and nav links now match the main propagation map
layout. Filter state managed by LiveView, pushed to JS via events.
Registered users can suggest edits to any contact's core fields
(callsigns, grids, band, mode, timestamp). Edits enter an admin
approval queue with field-by-field diff view. On approve, changes
are applied and enrichment re-enqueued if grids/band changed.
Users receive email notification on approve or reject.
Also updates dependabot.yml for mix ecosystem.
- Callsign input filters contacts where either station matches
(case-insensitive substring match, debounced 300ms)
- Band checkboxes now show per-band count of visible contacts
- All/None buttons for quick band selection
- Header count updates dynamically with filters
- Complete rewrite: rebuilds map on any filter change instead of
toggling individual layers (simpler, handles cross-filter correctly)
The sidebar and mobile floating controls overlay the dark map tiles
but inherited light theme colors, making dropdowns, inputs, and
menus invisible (white-on-white). Adding data-theme="dark" forces
all daisyUI components within these containers to use dark variants
regardless of the page's theme setting.
When clicking a grid point, fetches the latest NEXRAD composite
reflectivity and identifies rain cells within 300 km that could
enable rain scatter contacts. Shows:
- Scatter classification (excellent/good/marginal/none)
- Top 3 cells with dBZ, distance, bearing, and relative signal
- Colored circle markers on the map at rain cell locations
- Markers sized by reflectivity, colored by intensity
Uses simplified bistatic radar equation accounting for reflectivity,
frequency-dependent scattering (Rayleigh/Mie), and R^4 path loss.
NEXRAD cells sampled every ~5 km within bounding box for efficiency.
Terrain elevations now include the earth bulge correction, so the
profile visually humps up in the middle relative to the straight
LOS beam — showing how the curved earth rises into the signal path.
Uses actual k-factor from HRRR refractivity when available, otherwise
standard 4/3. For a 300 km path at k=4/3, the midpoint bulge is
~2,650 m (8,700 ft).
- Round grid-derived lat/lon in maybe_fill_latlon changeset step
- Format lat/lon to 6 decimal places on index table
- Migrate existing beacon data to 6 decimal precision
- Add comma separators to EIRP mW display (e.g. 10,000 mW)
- Extract shared add_commas helper for format_freq and format_mw
Height in feet doesn't need decimal precision. Migrates the DB
column, updates schema type, and strips trailing .0 from form
input so the integer cast succeeds.
- Add CommaNumber JS hook for live comma formatting while typing
frequency MHz in the beacon form
- Strip commas server-side before changeset validation
- Order beacon list by most recently added (desc inserted_at)
- Round lat/lon to 6 decimal places in changeset and display
- Round height_ft to integer in changeset and display
- Display coords at 6 decimal places on show page
When a contact is linked to a logged-in user account, display that
user's callsign in the Submitted column instead of a generic "Yes".
Anonymous submissions still show "Yes"; scraped contacts show an em
dash.
Add a per-entry progress bar (with cancel) while a CSV streams in, and
replace the small post-commit alert with a prominent "X contacts
submitted" confirmation card.
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.
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.
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.
- 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
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
- 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
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.
