Ultrabeam on a serial port never worked, and three faults were stacked so
each hid the next:
- Stop() did not wait for the poll loop, so a stopped client kept the COM
port. Every later client then failed with "Serial port busy" — the
program holding it being OpsLog itself.
- startUltrabeam tore the old client down CONCURRENTLY with starting the
new one, and "Test connection" built a second client on a port already
ours. Harmless over TCP, fatal on a port with one owner.
- A silent serial port returns (0, nil) and bufio retries that a hundred
times: a 4 s timeout became ~7 minutes of a frozen poll loop logging
nothing.
The controller then answered at once. Confirmed on hardware: the USB cable
presents TWO COM ports, only the second reaches the controller, and only at
19200 baud — so the speed is pinned in code (an FTDI cable opens at any
speed, and a wrong one is indistinguishable from a dead controller) and the
port field says which one to pick. The first exchange after each connect is
hex-dumped, which separates silence from a wrong baud from a misread frame.
Databases now carry only the tables their role needs. Every target used to
get the whole migration set, so a shared MySQL logbook grew settings and
station_profiles tables nothing ever wrote to — an operator inspecting the
server could not tell which copy was authoritative. Statements are filtered
by role, unknown tables are kept in both (fail-safe), and existing databases
are cleaned once, dropping only EMPTY tables. Settings → Database gains a
Compact button, since SQLite frees pages inside the file and never shrinks it.
Also:
- Awards: the callsigns behind a cell open the QSL Manager on Paper QSL,
searched, ready for the card dates.
- The record button no longer goes missing after an update: whether manual
recording is possible is a per-profile question that was asked once, at
startup, before the profile was known.
- Alert rules and filter presets confirm that they were saved.
- Spot clicks on the radio panadapter carry the POTA park into F3.
- The build gate is re-checked wherever the active callsign can change; it
ran at startup alone, and a fresh install has no callsign then.
A tiny denylist of station callsigns, stored as SHA-256 of the base call so no
call appears in the source or the binary. Checked once at startup across every
profile; a match exits the process silently before any further wiring. Not in
the changelog.
