ew8bakandClaude Opus 4.8 432c0285f0 feat: QO-100 NB transponder bandplan overlay on spectrum
Add a thin colored strip along the bottom of the spectrum (above the
ruler) showing the QO-100 narrow-band transponder bandplan: mode
segments (CW ONLY / NB DIGI / DIGI / SSB / MIXED MODES) plus the three
beacons (CW / PSK / EXP) as muted-red cells at their ranges.

- New unit BandPlanOverlay.pas (TBandPlanOverlay), modelled on
  VfoOverlay: content rendered once into a cache bitmap, per-frame cost
  is just a constant-alpha composite (CPU) / one textured quad (GL).
  Cache invalidates only on view change (center/span/width) so it idles
  while the QO-100 downlink display is static.
- Wired into both render paths: SpectrumView (CPU composite) and
  SpectrumViewOpengl (texture, re-uploaded only when dirty).
- MainForm: SetView fed from SyncSpecViewFreq; visibility gated by
  InQO100 (Pluto + full-duplex transponder), like RX MUTE / BEACON.
- DPI-robust: strip height scales with Screen.PixelsPerInch and the font
  height is tied to the strip height (not point size), so labels always
  fit at any Windows scaling.
- Segment/beacon frequencies and colors are a single editable table.

ew8bakandClaude Opus 4.8 3f0e4204c2 fix: unify beacon decoder filter marker (CPU matches GL)
The narrow beacon decoder filter marker rendered differently in the two
spectrum views: CPU drew a translucent filled band (BlendBand) plus a centre
line, while OpenGL drew three plain vertical lines (both edges + centre), so
it looked like one band on CPU and "two parts" on GL.

Make the CPU path draw the same three lines as GL — consistent look and
cheaper (drops the per-frame per-pixel alpha blend for this marker; BlendBand
is kept for the RX/TX passband shading).

ew8bakandClaude Opus 4.8 c063d7a197 feat: QO-100 central beacon BPSK decoder (Milestone 1 — stable demod)
Декодер центрального маяка QO-100 (10489.750, AO-40 BPSK 400 бод): фронтенд
до мягких символов + констелляция, с устойчивым захватом несущей/символа.

Цепочка (BeaconDecoder.pas): NCO-снос смещения → boxcar-децим до 9600 →
RRC матч-фильтр → AGC-нормировка → Gardner timing → Costas BPSK с frequency
offload в пред-RRC NCO. squaring-FFT оставлена индикатором несущей (prom).

Ключевые решения по итогам эфирной отладки:
- invert=True для тракта QO-100 (LNB+трансвертер зеркалит спектр).
- Декодер развязан от beacon-lock (тот ретюнил железо, рвал IQ).
- AGC-нормировка петель: сигнал ~-60 dBFS замораживал Costas/Gardner.
- Frequency offload: накопл. снос Costas стекает в FResidInc (без потолка
  ±π/символ) → держит ошибку наведения (1пкс≈300Гц) + дрейф LNB.

Интеграция: тап IQ в WDSPEngine.PushIQItemToDSP; RadioController владеет
декодером, клик-наведение (ПКМ BEACON + ЛКМ/Shift+ЛКМ по спектру); узкий
фильтр-маркер в SpectrumView/GL; окно констелляции BeaconScopeForm; файловый
лог HOME/ewsdr_beacon.log для диагностики.

Milestone 2 (далее): FEC — Viterbi k=7 + RS(160,128) + интерливер + дескремблер.

ew8bakandClaude Opus 4.8 4728e02459 feat: QO-100 beacon lock — robustness, persistence, FT8-aware UI
Builds on the beacon-lock baseline: keeps the proven display-FFT control
path (hardware-LO trim folded into the active transverter LOError), and
hardens it. The narrowband NCO/FLL scaffold (BeaconLock.pas) is removed —
it was never in the control path.

- RadioController:
  * Persist live: each correction folds straight into the active xvtr
    LOError (visible in Settings, survives restart as LNB calibration);
    disk writes throttled. FBeaconLockHz is now only a session indicator.
  * Robust tracking vs nearby signals: narrow ±2 kHz gate while locked
    (±6 kHz only for acquisition), slew-rate outlier rejection (a sudden
    centroid jump = interferer, not slow LNB drift → ignored), and lobe
    shape validation in MeasureBeaconFFT (width + power symmetry) so a CW
    carrier / one-sided neighbour isn't mistaken for the BPSK beacon.
    Prominence measured over the in-window noise floor (gate-width robust).
  * Fast convergence: feed-forward (predict post-retune position so the
    window follows the beacon through the jump) + near-deadbeat correction
    on the manual click → one click locks instead of repeated tapping.
  * Single central BPSK beacon (10489.750); dead CoarseBeaconOffset and
    unused throttle counters removed; stale NCO/FLL/4 Hz comments fixed.
- WDSPEngine: drop the per-sample TBeaconTracker RX-IQ tap (tracker gone).
- MainForm: BEACON is now a plain button, shown only on Pluto in a
  transverter. Lock status (off / click / search / LOCK + correction +
  prominence) moves to status-bar field 7 in place of PLL on Pluto;
  openHPSDR keeps PLL there.
- SettingsForm/StatusBar: widen LO Error field to ±10 MHz (QO-100 LNBs
  drift hundreds of kHz) and widen status field 7 for the beacon text.

ew8bakandClaude Opus 4.8 42610b304e feat: QO-100 beacon lock — stabilise LNB drift to NB transponder beacon
Click the beacon on the spectrum; the controller tracks it and continuously
trims the transverter LO so the whole downlink stays put as the LNB drifts.

- BeaconLock.pas: TBeaconTracker scaffold (narrowband NCO/FLL) — kept but no
  longer in the control path (FLL diverged on the suppressed-carrier BPSK
  beacon + Pluto DC offset). Measurement now uses the proven display-FFT path.
- RadioController: FBeaconLockHz folded into XvtrTranslate (on top of LOError).
  MeasureBeaconFFT finds the beacon by POWER-WEIGHTED CENTROID of the lobe
  (BPSK has a suppressed carrier → broad symmetric ~2.4 kHz lobe, not a line;
  a peak-finder jitters, the centroid sits on the carrier). Track position in
  ABSOLUTE display Hz (FBeaconTrackHz) so scrolling the waterfall/centre never
  moves the search window off the beacon. Closed loop: e = tracked - ref,
  d(e)/d(LockHz) = -1 -> LockHz += gain*e; settle cooldown after each correction
  (display-FFT lags the LO retune -> avoids overshoot); deadband 75 Hz +
  centroid/prominence smoothing + lock hysteresis for a steady lock.
  Correction applied only after the user clicks (manual seed), so a crowded
  band can't pull a neighbour to the reference.
- WDSPEngine: SetBeaconTracker + RX-IQ tap (tracker idle now, ~1 check/sample).
- SpectrumView + GL: beacon markers — green = reference (10489.750), orange =
  tracked centroid.
- MainForm: BEACON button (RX block, XVTR-only). Flow: BEACON -> "CLICK BCN"
  -> click beacon -> "L<corr> /<prom>". ServiceBeaconLock driven by MeterTimer.

Reference defaults to the middle BPSK beacon 10489.750. Tested on-air against
Es'hail-2: locks and holds, survives waterfall drag.

Uladzimir KarpenkaandClaude Opus 4.8 655d242d02 Add Spectrum gradient fill toggle in settings
Mirror the existing Wideband gradient fill option for the main spectrum:
a "Spectrum gradient fill" checkbox on the Display settings tab gates the
under-curve gradient in TSpectrumView.DrawSpectrum. The curve, grid,
filter band and VFO markers always draw; only the gradient is optional.

Persisted as spectrum_fill in settings JSON (default True, preserving
current appearance). Wired through Settings -> SettingsForm visibility
event -> MainForm -> TSpectrumView.FillSpectrum, same path as
WidebandFill.

Uladzimir KarpenkaandClaude Opus 4.8 c3a8a14110 Drop per-frame alpha-restore pass on macOS spectrum
On Cocoa the full-bitmap alpha-restore pass is unnecessary: Canvas
operations keep alpha at $FF and the cached grid background is opaque,
so removing it cuts a full-frame O(W*H) pass per spectrum frame with no
visual change (verified on macOS).

Kept under {$IFNDEF DARWIN} for Qt6/win32 (different drawing backends
may zero alpha on antialiased edges) until visually verified there.

Uladzimir KarpenkaandClaude Opus 4.8 55d5bf01cf Optimize CPU waterfall/spectrum rendering
WaterfallView: drop per-frame TLazIntfImage + LoadFromIntfImage (device
bitmap recreation + full pixel-format conversion every frame). Write
pixels directly into the bitmap via BeginUpdate/ScanLine like
SpectrumView already does, with platform-native byte order (ARGB on
Cocoa, BGRA elsewhere).

Replace per-pixel float colorization with a 512-entry dB->color LUT
rebuilt only when WfLow/WfHigh/theme change beyond a small threshold.

Turn the bitmap itself into a ring buffer: each frame builds a single
new row and writes one ScanLine; scrolling is done at paint time via two
CopyRect calls. Removes both full-frame passes per frame (image memmove
+ buffer->bitmap copy), cutting per-frame cost from O(W*H) to O(W). TX
mode preserved by leaving out-of-span columns untouched in the row buf.

SpectrumView: rewrite the per-frame alpha-restore pass from a strided
per-byte loop to a sequential per-dword OR with the alpha mask
(bit-identical output, sequential memory access).

Uladzimir Karpenka a02d35fcce Fix macOS pixel format: use ARGB byte order in all raw ScanLine blending
On macOS Cocoa, TBitmap.pf32bit stores pixels in ARGB order
   (byte0=A, byte1=R, byte2=G, byte3=B) rather than BGRA used on
   Linux/Windows. All raw ScanLine pixel blending and channel mapping
   is now guarded with { DARWIN} to use the correct offsets.

   Also fix PortAudio library discovery on macOS: probe .dylib names
   (including Homebrew paths) before falling through to .so/.dll.

ew8bakandClaude Sonnet 4.6 3bfd9adf0d Fix spectrum invisible on win32 and mask WDSP FPU exceptions
SpectrumView: rewrite DrawSpectrumGradient to blend directly into
FSpectrumBitmap via ScanLine instead of TLazIntfImage+BitBlt (stale DC
on win32). Add alpha=$FF fixup pass so pf32bit Canvas.Draw renders via
StretchBlt not AlphaBlend. Remove FSpecGradImg/FSpecGradBmp fields.

MainForm: mask exZeroDivide/exInvalidOp in FormCreate so WDSP DLL
divide-by-zero does not crash the DSP thread on win32 (Qt6 already
masks FPU exceptions globally).

ew8bakandClaude Sonnet 4.6 7b4ea733a2 Align spectrum grid and ruler to FM tuning step
When FM mode is active, vertical grid lines and frequency labels snap to
FM channel boundaries (FM_STEP_HZ) instead of the fixed 8-division layout.
Grid and label density auto-adapt: lines thinner than 4px are thinned,
labels are spaced so they never overlap (short tick shown between labeled
lines). Grid cache invalidates on center-freq, step, or span changes.

- DUP: локальный режим отображения, при TX данные RX1, поверх рисуется
  TX-фильтр. Кнопка на левой панели рядом с CTUN. Аппаратной командой
  не является. Отдельный SetDisplaySourceTX в WDSPEngine, разделение
  TXMode (data) и TXOverlay (filter band) в SpectrumView.
- ATT on TX: 0..31 dB, default 31 (Thetis-style). UI на вкладке Transmit
  в группе Microphone. Передаётся в DUC Specific bytes 57/58/59
  (StepAtten0/1/2). Перепосылается при изменении.
2026-05-06 15:51:33 +03:00
ew8bakandClaude Opus 4.7 96d7e0c759 TX: фиксированный sample rate, per-device grid, CTUN-aware overlay, alpha-blend filter bands
Декаплинг TX от RX sample rate (как в Thetis):
- WDSPEngine.pas: константа TX_SAMPLE_RATE=192000, поля FTXSampleRate/FTXOutBufSize.
  TXA OpenChannel теперь использует FTXSampleRate как out_rate, TX-анализатор
  через SetDisplaySampleRate(TX_DISP_ID, FTXSampleRate). ProcessTXBlock работает
  с FTXOutBufSize вместо FBufSize. Public TXSampleRate для MainForm.
- MainForm.SendDUCSpecificFromSettings: DUC0Rate теперь берётся из
  FDSPEngine.TXSampleRate, а не из RX-настроек — TX всегда 192k независимо от
  выбранного RX-rate (48/96/192/384k).

DUC Specific cache + keepalive resend (HPSDRNetwork.pas):
- FCachedDUCSpec/FCachedDUCValid параллельно DDC-кэшу.
- KeepAlive thread в первые 5s после Run=1 переотправляет и DDC, и DUC
  Specific — устраняет гонку, когда DUC настройки терялись железом.
- Disconnect сбрасывает оба valid-флага.

Per-device TX grid settings (Thetis-style):
- Settings.pas: TXSpecRefLevel/TXSpecRange/TXSpecGridStep в TTXSettings
  (defaults 0.0/80.0/10.0). LoadTX/SaveTX — ключи tx_spec_ref_level/range/grid_step.
- SettingsForm.pas: новая группа \"TX Grid\" во вкладке Transmit
  (RefLevel edit, Range edit, GridStep combo). CollectTXFromUI читает значения,
  LoadTXSettings заполняет UI.
- MainForm.pas: поля FTXSpecRefLevel/Range/GridStep, ApplySpecViewGridFromState
  пушит в FSpecView либо TX, либо RX параметры в зависимости от FTransmitting.
  ApplyGridParams (RX-путь) уважает FTransmitting и не перебивает TX-grid.
  OnTXSettingsChange при активном TX моментально применяет новый grid.

TX-aware spectrum/waterfall с CTUN-выравниванием (SpectrumView.pas):
- Поля FTXMode/FTXFreq/FTXSpanHz/FTXVfoIndex. TXSpanHz=192000 при создании.
- DrawSpectrum/DrawWaterfall в FTXMode мапят данные TX-анализатора (192k вокруг
  FTXFreq) в RX-координаты FCenterFreq/FSpanHz. Формула:
    freq = FCenterFreq - FSpanHz/2 + x*FSpanHz/W
    idx  = (freq-FTXFreq + TXSpanHz/2)/TXSpanHz * (SrcCount-1)
  Вне диапазона — спектр уходит в -200 dB; водопад копирует пиксель из
  предыдущей строки (FWfPixels[X+W]) — вместо чёрной полосы продолжает
  скроллиться старая RX-картинка.
- Эффект: при CTUN ON TX-сигнал рисуется на полосе фильтра (на VFO), а не в
  центре. При RX rate ≠ 192k частотная сетка совпадает между RX и TX
  автоматически (ruler всегда в RX-координатах).
- MainForm.SyncSpecViewFreq/ApplyMOX обновляют TXFreq/TXVfoIndex/TXMode при
  каждом PTT и смене VFO; учитывается split (FSplitTxB → TXVfoIndex=1).

Alpha-blended filter bands (визуальный feedback TX/RX):
- SpectrumView: PixelFormat:=pf32bit, процедура BlendBand через ScanLine[Y]
  внутри BeginUpdate/EndUpdate. Альфа-смешение по формуле
  (a*src + (255-a)*dst) / 255 для каждого канала BGR.
- В FTXMode полоса фильтра становится полупрозрачно красной. Если split
  (FTXVfoIndex<>FActiveVfo): на RX-частоте полоса зелёная, на TX-частоте —
  красная (CalcFilterBandX вычисляет границы для произвольной VFO-freq).
- При FTXMode=False — старое поведение (сплошная заливка SpecFilter).

Build: lazbuild --ws=qt6 ewsdr.lpi — clean, 0 errors.

- WDSPEngine: ActiveDisplayID switches RX/TX in UpdateSpectrum
- WDSPEngine: RX audio muted while TX active to avoid local feedback
- WDSPEngine: default EQ frequencies in Create (zero freqs broke TX chain)

- AudioInput: Available counter for non-blocking pull
- MainForm: PullSoundCardMic, BuildMicLineSelectByte, SendDUCSpecific
  with mic bias/boost/line/PTT bits, OnTXSettingsChange
- MainForm: auto-switch MicSource on TX device select, TX diagnostic
  in StatusBar panel [5]
- SettingsForm: new Transmit nav page with Microphone, Filter, Dynamic
  processing, EQ, AM/FM/CTCSS, TX Display sections
