The US 9cm amateur allocation was cut from 3300-3500 to 3300-3450 MHz
in 2020, so 3456 (the legacy weak-signal calling frequency) is no
longer in-band. Move the canonical key to 3400, migrate existing
contacts, and keep 3456 input resolving to 3400 via the
nearest-band snap so historical ADIF/CSV logs still import cleanly.
Expands submittable-contact bands to include 6m, 2m, 1.25m, and 70cm
(as 432 rather than the old 440 placeholder). Each new band gets an
explicit allocation window in BandResolver.nearest_band so ADIF FREQ
fields near the amateur allocations resolve correctly while 60-900 MHz
frequencies outside those windows are still rejected. Microwave
(>= 900 MHz) snapping is unchanged — nearest-band match across the
full @allowed_bands list.
Also adds BandConfig entries for 50 and 222 (tropo-only config, same
pattern as 144/432). Sporadic-E / F2 / meteor scatter modeling is not
yet in scope — ionosphere data is only used to compute an Es readout
on /path for 50/144/222/432.
Profile page:
* New MicrowavepropWeb.UserProfileLive at /u/:callsign is a public
page showing a user's contacts and beacons. Resolves case-
insensitively so /u/w5isp and /u/W5ISP are the same thing; unknown
callsigns redirect to /. Uses daisyUI card / stats / table
components with an avatar-placeholder initial and hero icons.
* Accounts.get_user_by_callsign/1 (case-insensitive) plus
Radio.list_contacts_for_user/1 and Beacons.list_beacons_for_user/1
back the page. Beacons list includes both approved and pending so
owners see their drafts.
* The top nav bar and the three LiveView sidebars (MapLive,
WeatherMapLive, ContactMapLive) now render the logged-in callsign
as a navigate link to /u/:callsign instead of a static label.
* Nine new tests cover the lookup, the LiveView render, and the
ownership-scoped queries.
Flexible band input:
* New Microwaveprop.Radio.BandResolver module converts any of:
ADIF wavelength labels ("33cm", "1.25cm", "6mm", case/whitespace
insensitive), numeric frequency strings ("903.100", "10368.000"),
and canonical MHz integers into the one of the site's known bands.
Returns the nearest allowed band for numeric inputs >= 900 MHz,
nil otherwise.
* 902 MHz is added to Contact.@allowed_bands, ContactEdit.@allowed_bands,
AdifImport.@allowed_bands, and the BandResolver list so "33cm"
round-trips end-to-end.
* AdifImport and CsvImport now delegate band resolution to
BandResolver, and Radio.create_contact/2 normalizes the :band attr
on the way in so the manual form and any API callers benefit too.
CsvImport's "invalid band" tests previously used 99999 MHz which
the new resolver snaps to the nearest allowed band; swapped to
"notaband" which is truly unresolvable.
Contacts and beacons list UX:
* Remove the "Submitted" column from /contacts — it duplicated info
already visible on the detail page and was pushing the real
columns off narrow viewports. submitted_cell/1 and its three
column-specific tests go with it.
* Hide the Lat / Lon columns from /beacons — six decimal places of
coordinates weren't useful next to the grid square and took a
disproportionate amount of row width.
