An ERC (Easy Rotor Control, incl. ERC Mini) emulates Yaesu GS-232A/B, which is
exactly what the backend written for the microHAM ARCO already speaks — azimuth
out (Maaa), azimuth in (C), stop (S), which is the whole of what was asked for.
So this is two small gaps rather than a new backend:
- Serial speed was hardcoded to 9600. An ARCO's virtual COM ignores it, but an
ERC runs at whatever its own configuration sets, and a mismatch reads as a
dead rotator. It is now selectable beside the COM port.
- The entry was called "microHAM ARCO", so an ERC owner would never have found
it. It is named after the PROTOCOL now: "GS-232A controller (microHAM ARCO,
ERC…)".
The help text states the condition plainly in both languages, because it is the
one thing that will otherwise waste an evening: an ERC left on Hy-Gain DCU-1
speaks a different command set and simply will not answer.
Untested on hardware — I have no ERC here, and the GS-232 path itself is proven
on a real ARCO.
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
