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.

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.

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.

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).

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.
- Remove ResizeSMeter (Pango font measurement + multiple SetBounds) from 60 Hz timer tick;
it is still called on actual resize events
- Throttle UpdateAGCLines WDSP API calls from 60 Hz to ~10 Hz (every 6 ticks)
- Optimize spectrum alpha-fix loop: write-only byte access instead of read-modify-write DWORD

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).

TSpectrumView remains the public facade for MainForm; waterfall, S-meter,
and ruler rendering are now in isolated units. Dead code removed.

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.

Power bar: minor ticks every 5% (between 0/25/50/75/100% main marks)
SWR bar: minor ticks at integer values 2,3,4,6,7,8,9 (between 1/2.5/5/10)
Applied to both desktop (SpectrumView) and web (paintTXMeter JS)

- S-meter panel switches to TX mode when transmitting: single bar splits
into two sub-bars (power top, SWR bottom) at the same position/size
- Power bar: 0..PAMaxPower W, green; SWR bar: 1..10, amber/red past 2.5
- SWR > 2.5: red border, red label, "SWR High" warning text
- Remove PWR/SWR bars and labels from TX panel (left column)
- Remove FWD/SWR from status bar; remove frequency from RUNNING status

- Settings > Display: new "VFO Display" control to select max frequency
range (999 MHz / 9.999 GHz / 99.999 GHz), persisted as freq_mhz_digits
- FreqDisplay: extend digit map [0..10] to support up to 11 digit positions;
keyboard navigation adapts to MinMhzDigits dynamically
- MainForm/LayoutTopVfoBlock: VFO panel width scales automatically with
selected digit count using dynamic text measurement
- Web VFO: fix broken HTML (class attr not closed before data-s — wheel and
hover were completely non-functional); rewrite fmtVfo to use variable MHz
digit count synced from server state; fix missing </span> for .vfo-hz
- WebServer: publish freq_mhz_digits in state JSON; updated from
ApplyFreqMhzDigits so desktop and web stay in sync
- Fix Int32 overflow on frequencies above ~2.15 GHz: CATEngine.Pad V param
Int64, FormatFreq/FormatFreqSV Mhz var Int64 (Mhz*1000000 overflowed)

- 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.
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.

Empty waterfall now fills with FTheme.Panel (same color as PanelRight)
instead of FTheme.BG, so there's no visible seam before stream starts.
Correct TColor→BGRA conversion (R/B swap) applied.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Add FRulerLastSpan to ruler cache — previously only FCenterFreq
and ActiveVfoFreq were tracked, so span changes left the ruler
showing stale frequency step marks.

- New unit SpectrumView.pas (TSpectrumView): encapsulates all
spectrum, waterfall, ruler and S-meter rendering; ~900 lines
removed from MainForm.pas
- Fix marker bug: FMarkerActive/FMarkerX were duplicated in
MainForm and TSpectrumView — mouse handlers now write directly
to FSpecView, stale MainForm fields removed
- Fix filter band and ruler not following VFO: add SyncSpecViewFreq
helper called at every draw site and at top of SpectrumTimerTick
- Remove dead code: WFALL_PALETTE (34 lines), FSplitter, LblAGC,
LblVol, WinFirewall/IntfGraphics/FPImage from uses
- Fix pre-existing bug: SidetoneFreqLo := 600 overflowed Byte,
replaced with Hi(600)/Lo(600)
