Contacts can be marked private at submit time (single form, CSV
import, ADIF import) and edit time. Private contacts are hidden
from the public map, the public /u/callsign profile, and the
browse table for anonymous and non-owning viewers. The original
submitter and admins see them inline on the browse table with a
"Yes" badge, and the detail page shows a lock icon. Non-authorized
viewers get a 404 on the detail page.
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.
- Add contacts_inserted_at_desc_id_desc_idx so /contacts list runs as an
Index Scan (~0.4ms) instead of a Seq Scan + top-N heapsort (~77ms on
58k rows)
- Add Microwaveprop.Cache: tiny ETS-backed TTL cache for memoizing
expensive-but-stale-tolerant values
- Cache total_entries for unsearched /contacts page loads (30s TTL,
invalidated on insert)
- Cache the entire /contacts/map payload (pre-encoded JSON + band list),
moving load_contacts into Radio.contact_map_payload; invalidated on
new contact insert. Mount goes from ~150-300ms to ~5ms.
- Fix /map overlay blinking on load: reuse the Leaflet GridLayer across
renderScores calls and just redraw() against the updated ScoreGrid,
instead of removeLayer + new layer which flashed between tile regens
- Make mode optional on submission: schema change (null: true),
submission_changeset no longer requires it, blank strings normalise to
nil, CSV import accepts 6-column (no mode) or 7-column layouts
- core_components .input adds a red asterisk to labels when required,
giving users a visual cue for which fields must be filled on /submit
Rename all modules, functions, variables, routes, and UI text from
qso/qsos to contact/contacts. Database table stays as "qsos" to avoid
migration. Add /qsos -> /contacts redirects for old URLs.
