fix(maps): zooming stays centred on the grid and decode maps

The hard maxBounds added for the single-world look fought the zoom: with
the world smaller than the window the clamp dragged every zoom step into
a corner. The noWrap tiles already guarantee one world on their own, so
the bounds go — on both maps.

-TCI (Transceiver Control Interface) is a network interface for control, data transfer and
+A modern, fast ham-radio logger for Windows — single-strip entry, real-time CAT
-synchronization between transceiver/receiver, contest loggers, digital mode software, skimmers
+for **OmniRig**, native **FlexRadio/SmartSDR**, native **Icom CI-V** (USB **and**
-and other software, as well as external power amplifiers, bandpass filter units, antenna switches,
+remote-over-internet, replacing RS-BA1) and **TCI** (SunSDR / Expert Electronics),
-radio controllers and other devices.
+DX cluster with spot alerts, awards tracking, maps, contest logging, QSL
+management and a QSL-card designer. Built with **Wails v2** (Go backend +
+React/TypeScript frontend), **pure Go** (no CGO): SQLite for configuration,
+optional **shared MySQL** for the logbook so several operators can run one log.
+Fully themeable and bilingual (English / French).
 
-TCI was created as a modern alternative to the outdated COM port and audio cable
+Developed by **F4BPO**.
-interfaces, it uses a full duplex web socket protocol that runs on top of a TCP connection and
-serves for server-client communications, providing cross-platform connectivity. Transceiver works
-as a server, all other software and devices as clients. The server and clients can be inside the
-same computer (program-server, hardware log, etc.-clients) and/or in separate physical devices
-connected through the local network (classical transceiver, power amplifier, antenna switch, FFT
-unit, etc.).
 
-The TCI interface contains basic transceiver control commands (analog of CAT system),
+---
-receives CW macros from clients and broadcasts them, outputs transceiver IQ stream to clients,
-receives spots from skimmers and Internet clusters, receives/outputs audio signal to work in
-digital modes.
 
-The TCI uses an extensible architecture and can be supplemented with new functions and
+## Building / developing
-commands, while keeping the old ones operational. Thus, the TCI interface can be extended and
-supplemented to meet the specific needs of any software manufacturer and/or device
-manufacturer (receivers, transceivers, power amplifiers, switches, etc.). The presence of a device
-identifier allows the manufacturers of transceivers and receivers to switch to the TCI interface
-while maintaining the device model designation. The extensibility of the TCI interface allows you
-to create an individual set of commands and functions for each device model, while maintaining
-the basic command set inherent to all transceivers.
 
-Our company advocates universal unification of data exchange between devices and
+- **Dev:** `wails dev` (Vite hot-reload; Go methods reachable at http://localhost:34115).
-software by creating the TCI interface for this purpose. Modern transceivers and software must
+- **Build:** `wails build` (use the project's wails v2.11 — `~/go/bin/wails.exe`).
-communicate using one protocol - the TCI protocol.
+- **Regenerate Go↔TS bindings** after changing exported `App` methods:
+  `wails generate module`.
+- **Release:** `.vscode/release.ps1` (Ctrl+Shift+P → *Tasks: Run Task* →
+  *Release OpsLog*) — bumps the version, pushes source to Gitea, builds the exe
+  and publishes it to Gitea + GitHub releases.
 
-## Interface description
+---
 
-Any command represents an ASCII string that contains a command name and a list of
+## Logging
-arguments corresponding to this command. There are reserved characters that cannot be
-included in the command name and command arguments.
 
-List of reserved characters: «:», «,», «;».
+- **Single-strip entry:** callsign, RST tx/rx, name/QTH/grid, band/mode,
+  TX/RX frequency (split), start/end time, comment/note. The contacted entity's
+  **flag** is shown large next to the RST fields.
+- **Callsign lookup** (QRZ.com / HamQTH) with photo, auto-fill of name/QTH/grid
+  and the QRZ.com tab.
+- **Offline DXCC** resolution from `cty.dat` (country, CQ/ITU zones, continent),
+  with `/MM` `/AM` `/B` (beacon) and call-area (`/8`, `/W6`) handling, plus
+  ClubLog DXpedition date overrides.
+- **Editable lists** for bands, modes (with their default RST) and **satellites**
+  — the satellite name on the entry form is offered as a dropdown, because
+  SAT_NAME is compared character for character by the awards and by LoTW.
+- **Recent QSOs**, **Worked-before** matrix (per band/mode slot), bulk re-resolve
+  from cty/QRZ/ClubLog, bulk send to QSL services. A live **selection count**, a
+  **Select all / Unselect all** toggle, and a row limit that keeps the full log
+  fast **but is lifted while a filter is active** (every match is shown, not just
+  the first page).
+- **Advanced QSO filter builder** (field / operator / value, AND / OR, saved
+  presets) with filtered- and selected-row **ADIF export**.
+- **Find duplicates** (Tools) — groups QSOs by same call + band + mode (optionally
+  same day / minute) and lets you pick which to delete.
+- **ADIF 3.1.7 compliant** import/export: a full field dictionary, 30 promoted
+  columns, a generic "extra fields" editor and standard/all export modes.
+- **Profiles:** every setting is per-profile; each profile can point its logbook
+  at the local SQLite file or a **shared MySQL** database (multi-operator).
 
-Command structure:
+## Maps & antenna
-1. Name of the command;
-2. Separating character between command name and arguments «:»;
-3. Separating character between arguments «,»;
-4. End of the command character «;».
 
-If a command has no arguments, an end of command symbol is placed after the command
+- **Main view = two configurable panes** (per profile, Settings → General →
-name. If the command is invalid, it is ignored. The case of letters does not matter.
+  *Main view*): great-circle map, locator (street) map, the cluster grid, the
+  worked-before grid, recent QSOs, the **FT decodes**, or any of the radio
+  consoles — **FlexRadio**, **Icom**, **Yaesu**, **Elecraft K3/K4**, **SunSDR
+  (TCI)** — and the **Net control** panel. Up to four panes, in columns or a
+  quadrant.
+- **Great-circle map** with short/long-path distance & azimuth, selectable
+  basemaps (Light / Topo / Street / Satellite — Esri tiles, key-free and
+  labelled) and the **antenna beam lobe(s)** drawn from the rotor azimuth.
+- **Rotor compass** (azimuthal-equidistant, click-to-turn) driven by
+  **PstRotator** (UDP), a **4O3A Rotator Genius** (native TCP) or a **microHAM
+  ARCO** controlled natively — no PstRotator needed — over the **LAN** or **USB**
+  using its Yaesu GS-232A protocol.
+- **Ultrabeam** support (Normal / 180° reverse / Bidirectional): the radiating
+  direction is shown in green and the **mechanical boom** in grey, on both the
+  compass and the map, so you never lose track of where the antenna points.
 
-The ExpertSDR3 program acts as a server, which can have several client connections at
+## DX Cluster
-the same time, they will be synchronized with each other by the server. When connecting to the
-ExpertSDR3, the client receives the current status of the ExpertSDR3, first sending initialization
-commands, then parameters to set the status, such as frequency, modulation, etc.
 
-When a parameter change occurs in the ExpertSDR3 (server) program, the server notifies

+  **digital modes count as one** (DXCC-style) for the new/new-slot colouring and
+  the worked-before matrix badges (Settings → General).
+- **POTA** spots are tagged with their park reference (via `api.pota.app`).
+- **Spot alerts:** rules on call / country / band / mode /
+  spotter, with sound, visual and e-mail notification (Tools → *Alert
+  management*).
 
-The TCI protocol implements the transmission of receiver IQ stream to clients, which is

+  mode / split, UDP discovery, and **panadapter spots** (cluster spots pushed to
+  the Flex display; a click fills the call and **tunes the rig to the right
+  frequency AND mode**).
+- **Icom CI-V** — native, over the radio's **USB** port *or* over the internet
+  via the radio's **built-in LAN server** (see *Remote Icom* below). No RS-BA1 or
+  Remote Utility needed.
+- **Kenwood / Elecraft** — native ASCII CAT over USB or an RS232-to-Ethernet
+  bridge, for the K3 / K4 and the Kenwood dialect they share.
+- **Yaesu** — native ASCII CAT (FA/FB/MD/VS…), which replaces OmniRig for an
+  FTDX and gives the Yaesu console below.
+- **TCI** (WebSocket) — SunSDR / ExpertSDR3 and any TCI-compatible server:
+  freq / mode / PTT / split, panorama spots, **audio in both directions** and a
+  full console. See *TCI audio* below.
+
+**CAT sharing:** OpsLog can hand the radio on to other programs while it holds
+the port — a **Hamlib NET rigctl** server (WSJT-X, JTDX, MSHV, fldigi…) or a
+**TCI** server. One or the other, on a port you choose.
+
+Mode is taken from the radio; the digital sub-mode (FT4 vs FT8) is inferred from
+the frequency. **Per-band Flex RX/TX antennas** can be configured and are applied
+automatically on band change.
+
+### FlexRadio control tab (SmartSDR-style)
+
+Shown only when the CAT backend is a FlexRadio:
+
+- **Transmit:** RF power, tune power, TUNE, MOX, speech processor (NOR/DX/DX+),
+  VOX (+ level + delay), monitor (+ level), mic gain.
+- **Receive (active slice):** RX/TX **antenna** selectors and a **DAX** toggle
+  (TX audio through DAX, for WSJT-X & co), AGC mode/threshold, audio level,
+  NB / WNB / NR / ANF, and — on **SmartSDR v4** radios (8000 / Aurora series) —
+  the extra DSP tools **NRL, NRS, NRF** (with level) plus **RNN** (AI noise
+  reduction) and **ANFT** (FFT auto-notch), shown automatically when the radio
+  supports them. **RIT / XIT** with wheel / ± tuning.
+- **Antenna tuner (ATU):** tune / bypass / memories.
+- **Amplifier:** the amp card follows whichever amplifier is configured, with a
+  dropdown to pick it when **several amplifiers** are set up (e.g. two SPEs run
+  in parallel). See *Amplifiers & switches* below.
+- **Live meters** over the UDP VITA-49 stream: S-meter (S-units), forward power
+  (W), SWR, ALC, PA temperature, voltage, plus the amplifier's meters.
+
+### Elecraft K3 / K4 control tab
+
+Shown for the Elecraft and Kenwood backends: power, AF/RF gain, mic gain,
+squelch, preamp/attenuator, NB/NR/AGC, filter widths (200 Hz to 4.0 kHz, the
+K3 maximum and the one FT8 wants), antenna selection, MOX and the ATU
+(tap to tune, hold for in/out), RIT/XIT with ±10 / ±100 steps, key speed, and
+live S / power / SWR meters. The SWR is read from the radio's own `SW;`.
+
+### Yaesu control tab
+
+Shown for the Yaesu backend: power, mic gain, AGC, NB/NR, preamp/attenuator,
+filter width, RIT/XIT and the meters — the same shape as the others, driven by
+the FTDX's own CAT set.
+
+### SunSDR console (TCI)
+
+Shown for the TCI backend. Drive and tune drive, mic gain, TUNE, power and SWR
+while transmitting, volume, mute, squelch and its threshold, NB / NR / ANF,
+APF in CW, AGC speed, filter widths **offered per mode**, RIT and XIT, and the
+VFO lock. Levels can be dragged, scrolled, stepped or typed. The S-meter reads
+real dBm, so its S-units are arithmetic rather than a calibration guess.
+
+It costs nothing to keep open: TCI **pushes** every setting as it changes —
+including changes made in the radio's own window, which the console follows
+without asking anything.
+
+### Icom control tab
+
+Shown when the CAT backend is Icom (USB or network). A full RS-BA1-style console:
+
+- **Twin VFO readout** (MAIN / SUB) with the big tabular frequency, mode badge,
+  band and RIT/ΔTX offset, and a **mode-button row** (SSB / CW / RTTY / PSK /
+  AM / FM).
+- **Spectrum scope + waterfall** (panadapter): ON/OFF, CTR/FIX, double-click to
+  tune, and **◀ ⊙ ▶** buttons to centre the scope on the current frequency
+  (±50 kHz) and pan left/right.
+- **Live meters** always visible: S-meter (click → fill RST), power in watts, SWR.
+- **Receive DSP:** AF / RF gain, squelch, AGC, preamp, attenuator, filter
+  (FIL1/2/3), NB, NR, ANF and — **on CW only** — the **APF** (audio peak filter).
+- **Passband / notch:** Twin PBT (inner / outer), manual notch + position.
+- **Transmit:** RF power, MOX, TUNE, **split with an automatic offset**
+  (+5 kHz on SSB, +1 kHz on CW), and monitor. On **voice modes only**: mic gain,
+  speech compressor, VOX (+ gain + anti-VOX). Controls that don't apply to the
+  current mode are hidden automatically.
+- **Bands & antenna:** one-touch band buttons and ANT1/ANT2 selection.
+- **Clarifiers:** RIT and ΔTX with wheel / ± tuning (Ctrl+←/→ nudges RIT).
+- **Power ON / OFF** buttons (manual by design — the app never wakes the rig on
+  connect).
+- **CW keying** can run through the radio's own keyer (see *Keyers* below).
+
+### Remote Icom (over the internet, no RS-BA1)
+
+OpsLog speaks the IC-7610's built-in network protocol directly — it **replaces
+both the Icom Remote Utility and RS-BA1**. Enter the radio's IP, the Network
+User1 name/password and the CI-V address, and the whole Icom console works over
+the LAN/internet: login + token (auto-renewed), CI-V tunnel, receive-side
+retransmit for a rock-solid link even with the panadapter streaming, and manual
+power ON/OFF. (Audio is out of scope — use the radio in USB + a voice link such
+as Mumble.)
+
+## Keyers & audio
+
+- **CW keyer** with macros and F-key macros. The keyer engine is selectable:
+  **WinKeyer** (K1EL WK1/2/3 over a COM port), **FlexRadio CWX** (the radio's
+  built-in keyer over the SmartSDR API — type-ahead and backspace, no WinKeyer or
+  SmartCAT needed), **Icom** (the radio's own keyer over CI-V — no extra hardware,
+  works over the remote link too) or **TCI**.
+- **Digital Voice Keyer** (DVK): record F1–F6 voice messages and transmit them.
+- **QSO audio recording:** continuous rolling capture; on *Log QSO* the contact
+  is saved to a per-QSO WAV (`CALL_YYYYMMDD_HHMMSS.wav`); mixes RX + mic.
+
+### TCI audio — no virtual cable
+
+A SunSDR carries its audio on the same WebSocket as its commands, so OpsLog can
+take it directly. Pick **Radio (TCI network audio)** as the *From radio* or
+*To radio* device and the QSO recorder and the voice keyer work with no virtual
+audio cable, no second sound card and nothing to set in the Windows mixer.
+
+Transmit needs no setting up in ExpertSDR3 either: the audio source is named on
+each key-down, so it works in SSB as well as the digital modes, and the
+microphone stays the source for every transmission that is not a voice message.
+
+## Amplifiers & switches
+
+- **Amplifiers** — configure **one or several** amps (Settings → Amplifier is a
+  list; e.g. two SPEs run in parallel for more power). Each amp's control card
+  appears on the FlexRadio tab and in **Station Control**, with a dropdown to
+  choose which one it shows; the bottom status bar carries **one clickable chip
+  per amp** (green = OPERATE, orange = STANDBY, red = offline). Supported:
+  - **PowerGenius XL** (4O3A) over direct TCP — operate/standby, fan-mode
+    selector and fault display.
+  - **SPE Expert** (1.3K-FA / 1.5K-FA / 2K-FA) over **USB** (virtual COM) or the
+    **network** (RS232-to-Ethernet bridge) — operate/standby, ON/OFF,
+    Low / Mid / High output level, an output-power bar and live status (band,
+    SWR, PA current, temperature, warnings/alarms).
+  - **Acom** (500S / 600S / 700S / 1200S / 2020S) over **USB** or the **network**
+    (RS232-to-Ethernet bridge) — operate/standby/off and live telemetry (forward
+    & reflected power, SWR, PA temperature, band, fan, faults). Power-ON works
+    over a serial cable that wires the DTR/RTS lines.
+  - **Elecraft KPA500 / KPA1500** over **USB** (serial) or — on the KPA1500 —
+    over the **network**. Operate/standby, on/off, forward power, SWR,
+    temperature, supply voltage and current, the band, and faults named in plain
+    words rather than as a code. The amplifier follows the radio's band by
+    itself, on the link already open — it has a band command of its own, so no
+    second serial port is involved.
+
+  An amplifier that takes its band from a transceiver instead (Acom, SPE) can be
+  followed a second way: OpsLog answers its frequency polls as a Kenwood rig on
+  a **second COM port**, independent of the control link.
+- **Antenna Genius** (4O3A) antenna switch over TCP/GSCP — a docked A/B
+  antenna-switch widget, and an option to write the **selected antenna into
+  MY_ANTENNA** under the name the switch itself carries.
+- **Tuner Genius XL** (4O3A) over TCP — SWR and power, TUNE / BYPASS / OPERATE.
+- **Station Control** panel (dockable, drag-to-reorder widgets): the **rotator**,
+  **Ultrabeam** element control and **relay boards** — WebSwitch 1216H, KMTronic,
+  **Denkovi** USB (FT245 D2XX bit-bang, 4 or 8 relays) and generic USB-serial
+  (CH340 / LCUS, A0 protocol) — for station power, antennas and accessories.
+- **Relay auto-control** (Settings): switch Station-Control relays automatically
+  from the rig frequency / band (like PstRotator) — per relay, a frequency window
+  or a set of bands.
+
+## QSL & awards
+
+- **Awards engine:** built-in + custom award definitions (shared **globally**
+  across profiles) — DXCC, WAS / WAZ / WAC, WPX, IOTA / POTA / SOTA / WWFF,
+  **DDFM**, worked/confirmed/validated by band & mode, OR rules and manual
+  reference assignment, live reference detection on call entry, **reference-list
+  import** for totals/names, and a **Rescan** that re-pulls the logbook (picks up
+  fresh LoTW/QRZ confirmations).
+- **Award statistics** by band and by mode class, with the **DXCC Challenge**
+  worked out where it can be compared to LoTW's own figure — it counts confirmed
+  band-slots on ten bands, and 60 m is not one of them, which is the whole of the
+  usual discrepancy. The band columns follow the bands you actually have contacts
+  on, up to and beyond 23 cm.
+- **Russian districts (RDA):** an offline district database that knows where a
+  callsign was **on the day of the contact**, a bulk fill for existing QSOs, and
+  a comparison against the district an imported log carries — each disagreement
+  settled on its own row, with the choice written into the contact.
+- **QSL services:** ClubLog (batched ADIF upload), LoTW, QRZ.com, eQSL,
+  **Cloudlog / Wavelog** and **HAMLOG.online** — upload and **confirmation
+  download** (which auto-refreshes the award stats).
+- **QSL Card Designer** (see below).
+- **E-mail eQSL:** right-click a QSO → *Send eQSL by e-mail* via the configured
+  SMTP account. (Outlook/Hotmail disable basic-auth SMTP — use Gmail with an app
+  password, or a Microsoft app password.)
+
+## Contest logging
+
+- **Contest tab:** pick a contest (built-in ADIF `CONTEST_ID` list) and an
+  exchange (running serial or a fixed exchange). OpsLog auto-fills `CONTEST_ID`
+  and the sent/received serials (`STX` / `SRX`), enforces a window start/end,
+  flags dupes and keeps a live scoreboard.
+
+## Statistics
+
+- **Logbook statistics dashboard:** headline tiles (QSOs, unique callsigns, DXCC
+  entities, continents, % confirmed) plus charts — QSOs **by mode**, a per-band
+  **CW / phone / data** split, **activity over time** (rolling day / 7-day /
+  30-day / 12-month views), by operator and by continent. Date-range, per-operator
+  and per-contest filters, and a **Table** view that mirrors every chart.
+
+## Multi-operator live status (special events)
+
+For a multi-op special-event call on a shared MySQL logbook (e.g. **TM74TFR**),
+publishing is **automatic** — no setting to turn on. Each OpsLog instance
+heartbeats its current activity (operator call, band, frequency, mode) into a
+`live_status` table every ~15 s, and drops back to *off air* automatically 5 min
+after the last logged QSO. A small PHP renderer
+([`docs/livestatus/tm74-status.php`](docs/livestatus/tm74-status.php)) on your
+own web server reads that table and produces a live page/image you can embed on
+the station's **QRZ.com** bio (`<img src="…/tm74-status.php?img=1">`). OpsLog
+only writes to the DB — it is not a web server.
+
+## Net control
+
+- **Directed-net logging** (Tools → Net): a global roster (`nets.json`) plus an
+  in-memory active session — check stations in, then log them individually or the
+  whole net at once (**Log everyone**) using the CAT frequency. **Drag & drop**
+  between the two lists (roster → on-air starts a QSO, on-air → roster logs it),
+  and after each log the next on-air station is selected automatically so you can
+  chain contacts.
+
+## Appearance & language
+
+- **Themes:** four complete themes (Warm light, Warm dark, Graphite dark, High
+  contrast) plus **Auto** (follows the OS light/dark preference), selectable in
+  Settings → General. Every panel and every AG-Grid table follows the theme.
+- **Bilingual:** full **English / French** UI, with a first-run flag chooser and
+  a switcher in Settings → General.
+
+## Security
+
+- **Secret vault:** opt-in passphrase encryption of the stored passwords
+  (AES-GCM + PBKDF2). Encrypted values are portable; a single unlock prompt at
+  launch decrypts them for the session.
+
+## Integrations (outbound)
+
+- **UDP emitters:** push the current frequency to **PstRotator**, radio info in
+  **N1MM `RadioInfo`** format, or an **ADIF record on each logged QSO** — so
+  external tools (rotator control, digital apps, other loggers) stay in sync.
+- **CAT sharing:** a **Hamlib NET rigctl** or **TCI** server, so WSJT-X, JTDX,
+  MSHV, fldigi and the rest still reach the radio while OpsLog holds the port.
+- **WSJT-X / JTDX / MSHV** decodes over UDP: the heard stations feed the band
+  map, the alerts and — on a FlexRadio — the panadapter.
+
+## Other
+
+- **Autostart:** launch external programs (WSJT-X, JTAlert, rotator control…) at
+  OpsLog startup, skipping any already running.
+- **Backup:** optional database + ADIF backup at shutdown.
+- **Update check** at startup and every 5 minutes (and on opening Help → About),
+  with a toast (toggleable), plus a **What's new** dialog that shows the changelog
+  (English / French) on the first launch after an update — reopenable any time
+  from the Help menu.
+- **Anonymous usage telemetry** (a once-a-day heartbeat: random install ID +
+  version + OS — no callsign or QSO data; opt-out in Preferences).
+
+---
+
+## QSL Card Designer
+
+Tools → *QSL Card Designer…* turns a few photos into a polished eQSL card:
+
+1. Pick 1–6 photos (jpeg/png). OpsLog analyzes them offline (detail/luminance
+   grid) and proposes **3 designs** — callsign in the calmest zone of the best
+   photo, operator name, CQ/ITU zones + locator line, country flag, the other
+   photos as bordered inserts, and a per-QSO confirmation box.
+2. Pick a proposal and fine-tune it: click an element to select, drag to move,
+   change font / style preset (gel gold, gel silver, classic white outline,
+   script, flat) and per-preset knobs in the right panel.
+3. Save the template (photos are copied into `data/qsl/templates/<id>/`, so the
+   originals can move). One template can be the default per profile.
+
+Sending: right-click a QSO → *Send eQSL by e-mail*. The card is rendered with
+that QSO's data, rasterized to a ≤ 800 KB JPEG, archived in `data/qsl/outbox/`
+and sent through the configured SMTP account to the address found by the
+QRZ/HamQTH lookup. On success the QSO is stamped `EQSL_SENT=Y` (ADIF). The
+e-mail subject/body templates live in the designer
+(`{CALL} {DATE} {BAND} {MODE} {MYCALL}` variables).
+
+Fonts: Archivo Black, Lilita One, Baloo 2, Oswald, Great Vibes, Allura (all
+OFL, embedded — licenses in `internal/qslcard/assets/fonts/`); Cooper Black is
+offered when MS Office installed it. Flags: flag-icons (MIT), embedded for the
+commonly-worked DXCC entities.
+
+---
+
+## Importing a log
+

+// Package kpa talks to the Elecraft KPA500 and KPA1500 amplifiers.
+//
+// One package for both: they share the Elecraft command set — ASCII, a caret
+// prefix, a semicolon terminator, case-insensitive on the way in and upper case
+// on the way back — which is the same family as the K3/K4 panel in
+// internal/cat. What differs between the two models is the transport and which
+// commands exist, not the grammar.
+//
+// # Transports
+//
+// KPA500: serial only.
+//
+// KPA1500: serial, and a network server. Four things may be connected AT ONCE,
+// which is unusual enough to design around — the Host PC USB port, the XCVR
+// SERIAL connector when repurposed as a second host, ONE TCP client, and any
+// number of UDP clients:
+//
+//   - TCP on port 1500 (changed with ^CP). Single client. If the operator
+//     already has the Elecraft utility or another program on TCP, OpsLog will
+//     not get in, and the failure is a refused connection rather than anything
+//     the amplifier says.
+//   - UDP on the same port. Many clients, one command per packet and at most
+//     one response, and packets may be dropped under congestion — so it is the
+//     right choice for sharing the amplifier and the wrong one for a command
+//     that must not be missed.
+//
+// # Pacing
+//
+// There is NO flow control. The reference is explicit: pace commands by waiting
+// for the response to the previous one. So this client is strictly
+// question-and-answer on one connection, like the ACOM and SPE clients, rather
+// than firing a poll cycle and sorting out the replies afterwards.
+//
+// # Serial speed
+//
+// 4800 to 230400, 8N1, set on the amplifier (^BR / SERIAL SPEED HOST) and not
+// negotiated. Elecraft's own utility finds it by sending bare semicolons at
+// each speed until something answers — worth copying if operators turn up with
+// amplifiers whose speed they do not know.
+//
+// # What is settled, and how
+//
+// From the KPA1500 Programming Reference:
+//
+//   - ^SW is the SWR IN TENTHS. "123 is 12.3:1", so ^SW015 is 1.5:1. This was
+//     first taken from Hamlib's backend and is now confirmed by the document,
+//     which matters more than it sounds: a wrongly scaled SWR bar reports a
+//     good match on a bad antenna.
+//   - ^WS returns forward power AND SWR together, ^VI returns PA voltage AND
+//     current together. Two round trips instead of four on the link the display
+//     depends on while the operator is transmitting.
+//   - ^SF returns the fault log: index, fault code, a short name in quotes, a
+//     timestamp, and fault-specific values. ^FC describes the codes.
+//
+// # Not touched
+//
+// ^TX simulates a KEY IN — it makes the amplifier transmit from software — and
+// ^ON0 switches the main supplies off. Neither belongs on a poll loop or behind
+// a button that can be pressed by accident.
