Reported on an IC-9100: the MOX button does not transmit, it sets split. The
source sends the PTT command (0x1C 0x00) and nowhere sends the split one (0x0F),
so the discrepancy is between what OpsLog sends and what the rig acts on — and
that link has already been shown, in the same operator's log, to lose frame sync.
Rather than guess from the command table, this adds what settled the WinKeyer
bug in one line: the actual bytes. Settings → CAT → Log the CI-V protocol writes
every frame in both directions as hex. RX is traced BEFORE framing, since the
bytes as they arrived are what reveals a lost boundary — a decoded view would
hide exactly the fault being hunted.
Session-only, like the keyer trace: it is a diagnostic, and a log full of hex
helps nobody who forgot it was on.
I am not claiming a cause yet. The last time I inferred one from a protocol
document rather than from evidence, I inverted a digit and broke the case that
worked.
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
