Grid: RI0FA transmitted QN35 all evening and was logged with its licence
holder's home square. WSJT-X's logged ADIF usually carries no GRIDSQUARE, so
the lookup was the only source left — and QRZ/HamQTH describe where an operator
LIVES, which for an expedition is the wrong side of the planet.
The square heard on the air is now applied before the lookup runs, so
refineGrid has something to defend. It still upgrades a 4-character square to a
6-character one from the same field, and still refuses a finer square from a
different field.
SPE: decodeCSV marks the client connected on every frame it parses, and the
poll goroutine can be mid-read while PowerOff runs. The frame from a second ago
landed after PowerOff had marked the amp offline and put it straight back,
which is why OFF had to be pressed twice.
Frames are ignored for three seconds after the off key goes out — the window is
opened before the key is sent, so nothing already travelling can beat it. Time
bounded rather than latched: an amp switched back on at its own front panel has
to reappear without being told.
Switching an SPE amp off left the already-open connection reading as connected
(the amp stops answering once off, but the stale open handle kept the status at
"connected"), so the panel never showed OFF and PowerOn — which only wakes a
DISCONNECTED amp, and must NOT pulse RTS/DTR on a running one — did nothing
until the operator restarted OpsLog. PowerOff now drops the connection and marks
the amp offline, exactly as a fresh start would; the poll's plain reopen never
wakes a switched-off amp, so it stays off until the ON button's RTS/DTR edge.
Implements the SPE Application Programmer's Guide protocol: packets
0x55 0x55 0x55|CNT|DATA|CHK (sum%256), OPERATE key 0x0D (toggles STANDBY/OPERATE)
and STATUS request 0x90 whose 0xAA-framed reply is a 19-field CSV (mode, RX/TX,
band, power level, output W, SWR, V/I, temp, warnings, alarms). internal/spe
polls status ~1/s over USB serial (go.bug.st/serial, 8N1) or TCP (RS232-to-
Ethernet bridge) — same codec, different transport.
Wired via startPGXL (starts the SPE client for spe* types), bindings GetSPEStatus
/ SPESetOperate, and a live status card + OPERATE/STANDBY toggle in the Amplifier
settings panel. Only the two example-anchored commands are sent (safe); other
keystroke codes were ambiguous in the guide's table. Untested on hardware.
