- ApplyChannel now sets TrkDrive from Ch.Power; saves pre-channel level in
FPreChannelPower (works around TrkDriveChange clearing the field on assignment)
- Power is restored when tuning away from channel (CheckChannelActive) or on
first VFO movement after returning to band with no active channel (ApplyVfoA)
- Manual drive slider move clears FPreChannelPower so restore is skipped

- New ChannelStore.pas: TChannel record + JSON persistence (channels.json)
- New ChannelsForm.pas: full channel editor (list + fields, pre-fills from current radio state)
- CH button in RX block: left-click opens dropdown, right-click opens editor
- Active channel: button highlights with channel name, deactivates on VFO move
- ApplyChannel: auto-switches XVTR/HF band based on channel frequency; saves old
band state before switching to prevent cache corruption
- SaveCurrentBand: skip save when VFO > 61 MHz (prevents HF cache corruption
from VHF channel application without XVTR)
- DeactivateXvtr: save full XVTR state (was only saving LastFreq)
- CTCSS/RPT from channel marked as auto: cleared automatically when tuning away
from channel frequency; survives band switches via FXvtrSettings auto-flags
- TXvtrEntry: add LastCTCSSAutoActive, LastFMRptAutoActive fields

- Add PanelRXBlock between TX and Band with CTUN, VOL, NR/NB/SNB/ANF/MUTE
- Move AGC panel to sit directly below RX block for logical RX grouping
- Move DUP button into TX panel below MOX/TUN
- Rename PanelRX → PanelAGC to match its content
- Standardize block label top (2px) and first-control top (16px) across all

- Fix left panel width restore after hide: save actual DPI-scaled width before
zeroing instead of hardcoding 232, preventing panel truncation on Win32 with
display scaling enabled

Extract helpers out of MainForm into structured modules:
- BoardUtils: BoardTypeName, FreqToBandIdx (removes duplication with DeviceForm)
- WisdomBuilder: TWisdomBuildThread + TWisdomProgressDialog
- UISync: TDeviceFoundSync/TStatusUISync/TDDCSeqSync via callbacks
- PlatformUtils: HasOpenGLSpectrumSwitch, CurrentScreenDPI
Minor cleanup: unused local constants, stale comments in AudioOutput.
Replaces TProgressBar in TWisdomProgressDialog with TFlatProgressBar,
drawn entirely via Canvas (plain rectangle, no native widget styling).
Dialog now receives the active TAppTheme so both dark and light themes
are applied consistently to background, label, and progress bar.

- LFM: Position = poDesigned (was poScreenCenter, overriding our restore)
- RestoreWindowBounds: remove position scaling (L,T invariant across DPI);
scale size correctly per backend: LCLWin32 uses CurDPI/SavedDPI (physical px),
Qt6/GTK/Cocoa use SavedDPI/CurDPI (logical px, inverse); fix min-size
inflation on Qt6 (was MulDiv(900,DPI,96) which exceeds logical screen width
at 150%+ scale, forcing window to 0,0)
- SaveWindowBounds moved from FormDestroy to FormClose while window is still
stable; add guard for bogus RestoredLeft/Top values on Qt6 when maximized
- RestoreWindowBounds stores FRestoreL/T and re-applies position in AfterShowTick
(200ms after show) when WM frame extents are already known to Qt, fixing the
systematic right/down drift caused by unknown frame extents at FormCreate time
- Save and restore WindowState (maximized flag); skip AfterShowTick position
re-apply when window is maximized

SpectrumView: rewrite DrawSpectrumGradient to blend directly into
FSpectrumBitmap via ScanLine instead of TLazIntfImage+BitBlt (stale DC

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

Gives 44ms jitter margin for WiFi connections. Sound card mic path
is unaffected — StallCount never increments when FOnPullMic fills
the ring every tick.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Pre-roll bug: when MIC_PREROLL_SAMP is an exact multiple of OPUS_FRAME_SAMP
(1920/960=2), the N<=Want branch filled the buffer but never flushed it,
losing the first 40ms of audio and leaving the ring empty long enough for
silence blocks to be injected into WDSP.
StallCount threshold raised from 2 to 4 (~43ms) to cover OS scheduler
jitter of up to 22ms, preventing false silence injection when an Opus
frame arrives slightly late relative to the DSP tick.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Opus decodes 960 samples per frame; the TX DSP thread consumes
512-sample blocks. 960 mod 512 = 448, so the ring always kept a
sub-threshold tail, causing TTXDSPThread to skip ticks and starve
the DUC hardware every ~20 ms.
FlushMicToCallback accumulates samples in FMicStageBuf and calls
FOnWebMic only when a full 512-sample block is ready. The remainder
stays in the buffer until the next Opus frame arrives. This ensures
FTXMicRing always receives data in multiples of 512, eliminating
the 0 < Avail < 512 dead-zone entirely.
FMicStageLen is reset together with FMicPreRollPos on new TX session
to prevent stale samples from a previous session mixing in.

- Remove manual "Mic Source" (Radio/SoundCard) setting from UI and storage;
source is now determined automatically in ApplyMOX: HW PTT → txmsRadio,
MOX button/CAT → txmsSoundCard if audio device configured, else txmsRadio
- Replace "Line in" checkbox with "Mic jack" combo (Mic In / Line In);
when Line In is selected, Mic Boost is hidden and Line In Gain (-34.5..+12 dB,
step 1.5 dB) is shown and sent as DUC Specific byte 51
- Add Tip/Ring connector selector (Orion/OrionMkII boards 4/5 only, byte 50 bit 3);
control is hidden for other board types
- Fix byte 50 bit 1 (Mic Boost) suppressed when Line In is active
- Fix byte 51 comment polarity (was reversed: 0=+12dB; correct: 0=-34.5dB)
- New JSON fields: mic_line_in, mic_tip_ring, line_in_gain_db; mic_source removed
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
WebPageHtml.pas:
- Add MIC gain slider (0..300%) with localStorage persistence; inserts
Web Audio GainNode between MediaStreamSource and Opus encoder.
- Disable autoGainControl in getUserMedia so the manual gain actually works.
- Pre-create+resume AudioContext synchronously inside the MOX click handler
(before any await) so user-gesture context isn't lost during getUserMedia
on macOS/Android.
- Call startTXMic() from the click handler too — the call from applyState
runs in a WS-message context which mobile browsers reject.
- Re-resume txMicACtx on every MOX→TX (Android can suspend it between
cycles) and reuse the existing context instead of recreating per session.
- stopTXMic now a no-op: the previous flag reset created a race that spun
up duplicate pipelines on rapid RX→TX toggles.
WebServer.pas:
- Pre-roll cushion: hold first 40ms of decoded mic samples before flushing
to FTXMicRing, raising steady-state ring depth from ~9ms to ~50ms so
WiFi jitter no longer drains the buffer into silence ("robotic" voice).
- Wall-clock-based Opus PLC: synthesize up to 5 frames via
opus_decode_float(NULL) when packet gap exceeds expected 20ms cadence.
- A gap > 200ms is treated as a new TX session: pre-roll resets, PLC
is skipped (no useful decoder state).
- Local (non-web) mic paths are untouched — they bypass WebOnMic entirely.

PA calibration per band (HF and VHF):
- Add VHFBandCal[0..7] in TGlobalSettings (saved as vhf_cal_0..7 in JSON)
- Default HF cal updated to Thetis HERMES defaults (38.8-41.3 dB per band)
- Default VHF cal = 56.2 dB (Thetis HERMES XVTR default)
- SettingsForm: second group in PA tab "VHF Calibration (Transverters)" with
8 spinboxes VHF0..VHF7; labels dynamically show XVTR slot ButtonText
when LoadXvtrSettings is called (e.g. "VHF0 (2m):")
TX drive formula (CalcDriveByte) rewritten to match Thetis exactly:
drive_byte = min(sqrt(10^((10*log10(pwr_W*1000) - Cal)/10) * 0.05) / 0.8, 1.0) * 1.02 * 255
Cal = PA gain in dB (not a percentage); matches Thetis verified output
(Cal=63.1 + slider=100% + PAMax=100W → drive_byte=16, verified against Thetis)
Old formula Pos/100*Cal/100*255 was wrong: treated dB gain as linear percent
Fix stale FDriveLevel not updated on band/XVTR switch:
- Startup: FCurrentBand must be set before CalcDriveByte (was reversed)
- RestoreBand: recalculate FDriveLevel before ApplyVfoA network update
- ActivateXvtrBand: recalculate after FCurrentXvtr changes
- ApplyVfoA: recalculate when VFO crosses HF band boundary
- FreqDispBChanged: same for VFO-B band changes
- ApplyMOX(True): safety recalculate at PTT engage time

Web UI: stepSel.onchange now sends fm_step command to server when in FM
mode; option values stay in Hz so tuneStep works unchanged.
WebServer: add fm_step command handler and OnFMStep callback.
MainForm: wire WebOnFMStep -> SyncWebFMStep -> SetFMStep + SaveCurrentBand.
Web spectrum/ruler: vertical FM-step grid lines in drawSpec; FM-aligned
ticks and labels in drawRuler with auto label-density (short ticks between

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.

- WebServer: expose fmstep_idx in state JSON so web clients sync the
FM step from desktop state
- WebPageHtml: swap stepSel options to FM steps (6.25k/12.5k/20k/25k)
when mode=FM, restore HF steps when leaving FM; syncs fmstep_idx

- Add FM squelch panel (SQL toggle + slider 0..100, per-band save/restore)
with WDSP SetRXAFMSQRun/SetRXAFMSQThreshold (threshold = level/200.0)
- Add CTCSS panel with on/off toggle and custom flat-button tone picker popup

XVTR RF (xvtr_rf in Thetis) is dead code — GetXVTRRF() is never called.
Remove the field, UI column, save/load from TXvtrEntry. UseDDCIn is now

- Separate FPTTActive from FIsTransmitting so PTT bit in HP packet
can be sent as a second packet after Alex bit27 (T/R relay) is set,
matching Thetis behaviour: relay switches first, then PTT=1
- On TX stop: PTT=0 first, then Alex switches back to RX
- Add SendPTT(Active) method to THPSDRNetwork
- Reset FSeqHP to 0 in SetRunAndFreq(Run=True) to eliminate HP SEQ
ERROR caused by intermediate SendFullHP calls before Run=1 packet
- RebuildXvtrButtons: use dynamic BtnH/RowH/MaxBottom instead of
hardcoded px values so XVTR buttons scale correctly on HiDPI

gen1 (TXA PostGen) sits after all modulators and the bandpass filter,

Add 'dup' field to state JSON (FDisplayDuplex). In CTUN+non-DUP TX,

Track wheelActiveTs on each wheel tick; suppress server center_hz
overwrites for 300ms after last wheel event so localCenter stays at

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Click on spectrum/waterfall no longer sets localCenter immediately.
The filter passband now appears exactly at the clicked pixel instead of
jumping to screen center. Server's center_hz (arrives ~200ms later)
naturally re-centers the display once fresh spectrum data is ready.
VFO display wheel (vDispA/vDispB) now updates localCenter when tuning
the active VFO. Previously localCenter lagged behind, causing applyState
to teleport the filter back to center every 200ms (the "passes through
center" oscillation).
Spectrum canvas wheel (doWheel) is unchanged: user expects the spectrum
to scroll when wheel-scrolling over it, filter stays at center — correct.

Причина щелчков (особенно слышных в TUN с непрерывной несущей):
TX-поток ждал FTXMicSem с таймаутом PeriodMs (auto-reset event), а
PushTXMicSamples* сигналили семафор каждый push. PullSoundCardMic
зовётся из самого TX-потока → сем сигналится → следующий WaitFor
возвращается немедленно. Плюс bottom-check всегда фигачил silence-блок,
если Avail<BufSize (а это всегда так после inner loop).
В итоге на один реальный период радио (≈21мс @ 1024/48k):
Wake1 (timeout): pull → voice block + silence block
Wake2 (immediate, sem был set): pull N=0 → silence block
= 3 блока IQ × 4096 пар = 12288 пар вместо 4096. На 192k DUC это
≈585k sps вместо 192k → FIFO радио переполняется → щелчки.
Фикс:
- PushTXMicSamples* больше не сигналят семафор (TX-поток сам себя
будил через них). Сем оставлен только для будилки на shutdown.
- TX-поток тикает строго по таймеру, ProcessedAny-флаг гарантирует
silence-блок только когда в этом тике ни одного реального не было.
Per-tick теперь: ровно 1 блок IQ — точно соответствует темпу радио.

Два источника искажений при передаче с микрофона компьютера:
1. SoundCard mic путь в TX-потоке (WDSPEngine.pas) при неполном блоке
подменял голосовой хвост в кольце тишиной. PortAudio отдаёт по 128
сэмплов, в кольце часто < FAudioBufSize → ProcessTXBlock уходил в
else-ветку и слал блок нулей, оставляя голос на следующий тик.
Результат: чередование «голос/тишина» = треск ≈50–100 Гц.
Теперь подмена тишиной только при Avail=0; иначе ждём следующий тик.
Добавлен PushTXMicSamplesD — батч-пуш с одной будилкой семафора.
2. DUC IQ packetizer (MainForm.pas/OnTXIQReady) добивал последний
неполный пакет нулями. FTXOutBufSize не кратен 240 (4096 mod 240=16),
из-за чего в каждом TX-блоке возникал провал ≈1.16 мс каждые ≈21 мс
≈ 47 Гц гул. Теперь хвост переносится в следующий вызов через
FDUCPendingI/Q/Count; шлются только полные пакеты по 240 пар.
Дополнительно: ScaleIQ24 клампит результат в [-2^23, 2^23-1] чтобы
пики от EQ/компрессора (V чуть >1.0) не оборачивались через 24-bit
wrap → щелчки на громких сэмплах.

- SWR: было 1+sqrt(Pr/Pf) — теперь (1+ρ)/(1-ρ). Считается только при
FwdW>=1W и HPS_PTT=1, иначе 1.0. Cap 9.9.
- На RX FwdW=0 (ADC даёт шум).
- EMA-сглаживание (α=0.30/0.20/0.05) в DoUpdateStatus на UI-потоке.
- LblFwdPwr/LblSWRVal и StatusBar Supply/FWD/SWR обновляются из
MeterTimerTick (10 Гц), а не на rate HP Status (~150/с).
- PbFwdPower/PbSWR теперь Invalidate в таймере — бары двигаются.
- BtnTUN рядом с MOX. Включает SetTXAPostGenRun(TXA, 1) с тоном
(mode=0, mag=1.0, freq из настроек) и активирует MOX. PTT/HW
игнорируются во время tune.
- Drive в режиме TUN использует FTXSettings.TUNLevel вместо слайдера,
per-band калибровка FPABandCal применяется одинаково.
- Settings → Transmit → Tune (TUN): TUNLevel 0..100% (def 10),
TUNFreq 100..5000 Hz (def 750). Live-обновление во время tune.
- 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.

- Settings: TTXSettings record + LoadTX/SaveTX, JSON section "tx" per MAC
- WDSPEngine: separate TX_DISP_ID analyzer with own FFT/Window/Det/Avg
parameters, ApplyTXAnalyzerSettings + setters
- WDSPEngine: full TX chain setters (Filter/Compressor/Leveler/ALC/
PhaseRot/EQ/AMCarrier/FM/CTCSS) + ApplyTXChainSettings
- WDSPEngine: ProcessTXBlock now feeds TX analyzer in DISPLAY_BLOCK_SIZE
chunks (was passing whole FTXOut → analyzer ignored most of it)
- 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)
- WDSPEngine: PushTXMicSampleD + OnPullMicSamples for sound-card path
- 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
NOT YET WORKING: sound-card mic produces ring activity but signal still
not visible on TX spectrum/waterfall — needs further investigation.

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.
