chore: release v0.23.1

The 0.22.7/0.22.8 breakage came from a Xiegu-reported fault being fixed
inside the Yaesu and Kenwood backends. The lesson is structural: nothing
a backend does may be steered by another backend's report or another
backend's setting.

The lower-lines checkbox introduced for 0.22.9 was still one shared key
applied to both Yaesu and Kenwood — the same reflex in miniature. It is
now cat.yaesu.low_dtr_rts and cat.kenwood.low_dtr_rts, each checkbox in
its backend's own settings block, each wired only to its backend. The
shared key never shipped, so nothing needs migrating.

+# ACOM built-in ATU — what we know, and why OpsLog does not drive it
+
+Session of 2026-08-02 on F4BPO's friend's **ACOM 500S**, serial link, telemetry
+trace. Written down so nobody repeats the work. **Conclusion first: the tuner
+cannot be started over the serial link, and the attempt to work around that was
+abandoned.**
+
+## The tuner is PA state 8
+
+Frame byte 3's high nibble is the PA status. ACOM's own list (recovered by the
+ACOM-Controller project) has no entry for 8; it is the antenna tuner. Confirmed
+twice, front-panel TUNE, with the byte-level trace running:
+
+```
+14:47:20.745  state 8 step 0   ← TUNE pressed. err=FF
+14:47:22.588  operator keys a carrier (FT-891, FM, 31 W, 3.6358 MHz)
+14:47:24.006  state 8 step 2
+14:47:25.201  state 8 step 4
+14:47:27.457  state 8 step 5
+14:47:30.092  state 5 STANDBY  ← accord finished
+```
+
+Byte 3's **low** nibble is a step counter through the accord: `0 → 2 → 4 → 5`.
+Step 0 means *armed, waiting for RF* — in the first of the two runs the
+amplifier sat there **30 seconds** untouched before the operator transmitted.
+
+`paStatusNames[8] = "TUNE"` in acom.go is the only thing kept from all of this.
+
+## The command does not exist in the state-command family
+
+Every action byte of `55 81 08 02 00 XX 00 CHK` was tried, each one from a
+**verified** STANDBY (an earlier sweep was worthless because its second code
+parked the amp in SERVICE, where it silently refuses everything — 17 false
+negatives). Result:
+
+| byte | effect |
+|------|--------|
+| 0x01, 0x02 | **reboot the amplifier** — it prints `AMPLIFIER: ACOM 500S / HELLO ME…` |
+| 0x04 | → SERVICE (state 4) |
+| 0x05 | → STANDBY (state 5) |
+| 0x06 | → OPERATE (state 6) |
+| 0x0A | → OFF (state 10) |
+| 0x03, 0x07..0x09, 0x0B..0x18 | nothing, state unchanged |
+
+The action byte **is** the target PA state — four independent confirmations.
+Which makes 0x08 the obvious candidate for TUNE. **It was tried, from a verified
+STANDBY, and does nothing.** State 8 is reachable from the front panel only.
+
+Going further would mean varying the other bytes of the frame. That is a large
+space, and 0x01/0x02 prove that bad values reboot a 500 W amplifier. Not worth
+it.
+
+## The workaround that was built and removed
+
+Since the amp waits, armed, for a carrier, OpsLog could watch for state 8 and
+supply one: memorise the mode, drop the power, switch to FM, key the PTT, wait
+for state 8 to clear, unkey, restore. It was implemented (`acomtune.go`, opt-in,
+Settings → Amplifier) and **removed** after the first hardware test:
+
+- the power change did not take effect, and
+- **the PTT was not released when the tune finished.**
+
+A logger that can leave a transceiver keyed is not acceptable, and the whole
+thing was scaffolding around a protocol we do not actually control. Removed at
+the operator's request: *"je veux qu'OpsLog soit solide et ça c'est de la
+bidouille."*
+
+If it is ever revisited, the unexplained part is why the tune-finished detection
+did not fire — `anyAcomTuning()` polled `StateRaw == 8` every 200 ms and should
+have seen the drop to STANDBY. Suspect the status snapshot, not the amplifier.
+
+## Loose ends worth knowing
+
+- **Frame byte 6 is a multiplexer.** The tail of the frame changes meaning with
+  it: `0x93` = bytes 48/49 carry the TX frequency in kHz (`62 1B` = 7010 while
+  the rig was on 7.010 MHz), `0x9D` = something else. Byte 70 looked like a
+  tuner flag for a while purely because of this — it toggles on its own several
+  times a minute. Do not read tail bytes without checking byte 6.
+- **Byte 5 bit 0x80 alternates frame to frame.** It is a sequence/parity bit,
+  not a command acknowledgement.
+- **Byte 66 (the error code) shows 0x14 / 0x8E / 0x69 / 0x0F during a normal
+  tune and during transmission.** `errText` renders those as "ERROR — see
+  display" and "Remove drive power", so an ACOM operator probably sees a false
+  alarm. This was never confirmed with the amplifier in OPERATE (it was in
+  STANDBY throughout, where drive genuinely is an error) — worth a look with a
+  clean log before touching the table.

+# Kenwood and Xiegu (native CAT)
+
+## Kenwood (USB, network)
+
+A native backend talks straight to a **TS-590 / TS-890 / TS-990 / TS-2000**
+over its serial port — frequency, mode, VFO, split and PTT, no OmniRig in
+between. **Elecraft K3/K4** speak the same dialect. Pick **Kenwood (USB,
+network)** in Settings → CAT.
+
+- **Serial**: COM port + baud.
+- **Network**: give a `host:port` instead — for a serial bridge (ser2net, an
+  Ethernet-serial adapter). *Not* the radio's own RJ45, which speaks Kenwood's
+  KNS/ARCP protocol.
+- Split is detected from FR/FT when the radio omits it from its status frame.
+- The backend was tested end-to-end against a TS-2000 emulator and reports
+  useful errors: a port that opens but stays silent is distinguished from one
+  sending data that never answers (the error quotes what arrived).
+
+## Xiegu (G90, X6100, X6200, X5105)
+
+These radios speak CI-V but with a **reduced command set** (no scope, no DSP
+block, no data mode), so they have their own backend — pick **Xiegu (USB)** in
+Settings → CAT. Frequency, mode, split and PTT.
+
+### PTT on a G90 — read this
+
+A **G90 ignores the CI-V PTT command**. That has three consequences:
+
+1. In the Xiegu settings, choose **how the rig is keyed**: CI-V command, RTS or
+   DTR — pick the hardware line your interface wires to PTT.
+2. WSJT-X & co transmit through OpsLog's **shared CAT link** (Hamlib NET rigctl
+   `127.0.0.1:4532` — see [[CAT Control]]): OpsLog converts the PTT request
+   into the hardware line. This is the supported path and it works.
+3. **WSJT-X + OmniRig will NOT transmit** a G90: OmniRig sends PTT as a CI-V
+   command, which the radio ignores. Either use the native Xiegu backend +
+   rigctl sharing, or configure the PTT line (RTS/DTR) inside OmniRig itself.
+
+### Keying on connect
+
+Behind an interface that carries PTT on a modem line (e.g. a DE-19), a G90 used
+to go **straight into transmit when OpsLog connected** — Windows raises DTR and
+RTS when a serial port opens. The Xiegu backend now drops both lines on
+connect, then drives only the line you selected for keying.
+
+## Notes
+
+- Both backends refuse a CI-V/CAT frame read at the wrong offset, so a garbled
+  answer can no longer turn into a phantom frequency.
+- The protocol trace (Settings → CAT) covers both — see [[CAT Control]].

+- **"Serial port busy" in the log** — another program holds the COM port
+  (WSJT-X, MSHV, another logger configured for direct CAT). Only one program
+  can own the port: let OpsLog hold it and point the others at **Hamlib NET
+  rigctl 127.0.0.1:4532** (Settings → CAT → Share CAT). Two masters on one
+  CI-V bus also cause garbled frames and erratic behaviour.
+- **The radio transmits as soon as OpsLog connects** — your interface reads DTR
+  or RTS as PTT. Xiegu drops the lines automatically; on Yaesu and Kenwood
+  enable the *lower DTR/RTS on connect* option. (It is off by default because
+  other interfaces stop transmitting with the lines low.)
+- **WSJT-X won't key a Xiegu G90 through OmniRig** — a G90 ignores the CI-V PTT
+  command. Use the native Xiegu backend (which keys RTS/DTR) + rigctl sharing,
+  or set the PTT line inside OmniRig. See [[Kenwood and Xiegu]].
+- **OmniRig frequency frozen / wrong VFO** — set **VFO to read** (A or B) in
+  the OmniRig backend settings; some rig files declare the wrong VFO.
+- **"OmniRig not found" with OmniRig running** — one of the two runs as
+  administrator and the other doesn't. Start both the same way.
+- **Icom: no CAT at all over USB** — the CI-V address must match the radio;

+# Yaesu (native CAT)
+
+A native backend talks to an **FTDX10 / FTDX101** (and close relatives) directly
+over the rig's USB/serial port — no OmniRig. Pick **Yaesu (USB)** in
+Settings → CAT: COM port + baud (FTDX10/101 default 38400).
+
+Frequency, mode, VFO A/B (MAIN/SUB on the 101), split and PTT are covered, and
+OpsLog **follows the VFO you are actually on** — the displayed frequency, the
+logged frequency and the VFO a cluster spot tunes. Split is worked out from
+which VFO transmits, so simplex on the SUB receiver is not shown as split.
+
+## The Yaesu console
+
+With the native backend connected, a console tab (and a Main-view pane) gives:
+
+- **S / PO / SWR meters** — power in watts on a curve measured against the rig's
+  own display, SWR as the ratio itself, with peak-hold so they stay readable
+  between CW words or SSB syllables.
+- **Band and mode buttons** — CW, RTTY, DIGI and PSK show their sideband; click
+  the active button again to switch it.
+- AF / RF / squelch, AGC, IPO–AMP1–AMP2, 6/12/18 dB attenuator, NB, DNR, narrow
+  filter, power, mic gain, VOX, split and **ATU tune**.
+- **SPLIT** places the transmit VFO up 1 kHz on CW/data, up 5 kHz on phone.
+- In CW the mic gain and VOX give way to a **CW card**: keyer speed, break-in
+  and ZIN (zero-in).
+
+Sliders only respond to the mouse wheel after you click them, so scrolling the
+panel can't change the transmit power by accident.
+
+## CW with the rig's own keyer
+
+A CW engine sends your macros with the radio's internal keyer (CAT `KY`) — no
+WinKeyer, no second cable. Pick **Yaesu (rig keyer)** in Settings → CW keyer.
+
+- Works on the **FTDX101 / FT-991A / FT-710** family.
+- An **FTDX10 does not accept it** (`KY` is refused, `DAKY` doesn't help) —
+  OpsLog says so and points to the **serial DTR keyer** on the rig's second COM
+  port (the *Serial port* CW engine), which works. See [[Audio and Keyers]].
+- CW speed is one setting everywhere: the console slider, the CW panel and the
+  rig's front panel stay in agreement.
+
+## Notes
+
+- A Yaesu that is switched off is reported as such (opening the port is not
+  "connected").
+- If your interface goes into transmit the moment OpsLog connects, enable the
+  **lower DTR/RTS on connect** option — see [[CAT Control]].
