Reported by an operator whose node sends little: nothing for two minutes, then a
reconnect — losing the login, the filters, and any spot that arrived during the
gap.
The read had a 120 s deadline and ANY error ended the session, a timeout
included. That reads a silence as a verdict on the link. It is not: a cluster on
a dead band legitimately says nothing for minutes.
Only a real error ends a session now. A genuinely dead peer is still caught, and
by the mechanism meant for it — TCP keepalive probes an idle connection and its
failure surfaces as an error on Read, not as a timeout. The dialer sets it
explicitly rather than inheriting a default, since it is now what the design
depends on.
One trap the advice this came from did not mention: ReadString returns the bytes
it HAD read along with the timeout. Discarding them would lose the first half of
any spot line straddling a deadline, so the partial is carried over.
Tested: a listener that goes silent past the deadline and then sends a spot —
the spot arrives on the ORIGINAL connection, and the listener never accepts a
second one. The tick is a var so that test runs in four seconds instead of
sixty; a slow test is a test that gets skipped.
Reported on 3 cm. cat.BandFromHz stopped at 23 cm, so a 10 GHz frequency came
back EMPTY — and an empty band is not cosmetic: the QSO is logged without one,
counts in no award slot, and exports with no BAND field. The low end was short
too (2190m / 630m / 560m).
Four band tables had to be extended because four exist: the CAT one, the award
plan in app.go, the cluster spot classifier, and the frontend's. Plus the places
that LIST bands — the QSO editor and award-definition pickers (you could not set
3 cm by hand either), the statistics axis, and the award band ORDER, where a
missing band sorts to the end instead of in frequency order.
Ranges and names are ADIF 3.1.7, which is what an export has to carry.
A test now pins one frequency per band across the Go tables and asserts they
agree — that is what was missing, four hand-maintained copies with nothing
checking them. It also pins that an out-of-band frequency stays empty rather
than snapping to the nearest band, which would file a QSO under a band the
operator never used.
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
