Settings → General, beside the language. An operator reading 2026-07-30 as the
7th of the 30th month is reading their own log wrongly, and that is a display
problem.
Storage stays ISO/ADIF, deliberately and permanently: it is what ADIF
specifies, it sorts correctly as text, and a stored format that followed a UI
preference would make the log unreadable the day the preference changed. Exports
and uploads are untouched.
Two details that decide whether it actually works:
- The columns are rebuilt when the format changes. The formatters are captured
inside AG-Grid's column definitions, so nothing else would notice and the
table would keep the old format until something forced a rebuild.
- main.tsx re-reads the choice after the portable prefs are pulled from the
database. The module reads localStorage at import time, which is BEFORE that
sync — so a copied data/ folder would have shown ISO until the next launch.
UTC is not part of the choice and never will be: a logbook is kept in UTC, and
showing local time would make the display disagree with the QSO's own record
twice a year.
Two white-screen reports are open — one after logging a 10 GHz QSO, one on
starting a DVK auto-call — and neither could be investigated, for the same
reason: a render error emptied the window and left NOTHING. No line in
opslog.log, no dialog, nothing the operator could send but the words "white
screen". A fault the user cannot report is a fault that cannot be fixed.
So before hunting either trigger, the reporting path:
- An error boundary catches a render throw, writes the error and component
stack to the app log through the new LogUIError binding, and shows it on
screen — selectable, with Copy and Reload.
- Global handlers catch what a boundary cannot: throws from timers, event
handlers and rejected promises. An auto-call loop lives entirely in
callbacks, which is exactly where the second report came from, and those
leave no trace at all today.
It deliberately does not try to resume: React cannot promise sane state after a
render throw, and a half-working logger would be worse than a clear stop.
This does not fix either crash. It makes the next occurrence arrive with its
cause attached, which is the step that has been missing.
Backend (Go 1.25 / Wails v2):
- QSO storage on SQLite (modernc) with embedded migrations (0001..0005)
- Streaming ADIF import (batch insert) + WorkedBefore per callsign and DXCC
- Callsign lookup with QRZ.com + HamQTH providers (primary/failsafe routing)
and SQLite-backed TTL cache
- DXCC resolver from cty.dat (auto-download, longest-prefix-match)
- Multi-profile operator identities (home/portable/SOTA/contest) — every
QSO stamps MY_* from the active profile
- CAT control via OmniRig COM on a single OS-locked goroutine, with
bidirectional sync (freq/mode/band/split/VFOs) and Rig1/Rig2 hot-swap
- Settings store (key/value), CAT debug log at %APPDATA%/HamLog/cat.log
Frontend (React 18 + TypeScript + Tailwind v4 + shadcn-style):
- Single-row entry strip with CAT-aware band/mode/freq, RST, Start/End
UTC, per-field locks (band/mode/freq/start/end) for backdated QSOs
- Topbar: live freq (MHz.kHz.Hz dotted), live UTC, band/mode/SPLIT badges,
CAT pill with rig selector and clickable Azimuth pill (rotor TODO)
- Settings tree: Profiles (Log4OM-style manager), Station Information
(edits the active profile), unified Callsign Lookup with Test buttons,
Bands/Modes lists, CAT
- Worked-before matrix (band × mode × class) with new-DXCC highlighting
- ADIF import from menu + Maintenance > Refresh cty.dat
