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

FM modulation:
- Replace 10 generic FM filter buttons with NFM (2.5kHz dev/11kHz BW) and FM
(5.0kHz dev/16kHz BW); deviation applied to both RX and TX via WDSP
- 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
(38 standard tones 67.0..250.3 Hz, default 67.0); tone selection and enable
state saved per band via SetTXACTCSS*
- FM panels (SQL, CTCSS) shown only in FM mode, layout via RelayoutBelowBands
- PanelFilter height shrinks in FM mode so panels sit tight below filters
- FlatButton: handle CMTextChanged to invalidate on Caption change
ADC settings (Dither/Random):
- Add DitherEnabled/RandomEnabled to TGlobalSettings (default true)
- Pass as bitmask to ConfigureDDCs DDC Specific packet bytes 5/6
- Exposed in Settings → Advanced tab with live apply via ApplyADCSettings
Web server settings:
- Add TWebSettings (enabled, port, bind_addr, user, pass) stored globally
- WebServer: configurable port/bind IP via ParseIPv4; Reconfigure method
- Exposed in Settings → Advanced tab with live apply via ApplyWebSettings

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
always True when in XVTR mode (previous default behaviour, XVTRRF=False).
Byte 1400 bit 0 (XVTR Enable / VHF T/R relay output) now follows Thetis:
- XVTR mode: set only when DisablePA=True (external T/R relay needed)
- HF mode: set when Alex.EnableXvtrHf is checked (Antenna tab)

CalcAlex0: Alex.RxOnly[band]=3 (XVTR checkbox in Antenna tab) now sets
XVTR DDC In only when XvtrActive=True (FXvtrEnable). Matches Thetis
Alex.cs behaviour: "do not use XVTR ant port if not using transverter".

- 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

- Add freq_a command: sets VFO A regardless of active VFO; fixes A=B and
SWAP when VFO B is active (prev. sent freq_b which overwrote wrong VFO)
- Add pend("freq") to B=A / A=B / SWAP to guard local display during round-trip
- RX step attenuator: HPSDRNetwork.SetStepAtten → bytes 1442/1443 in HP packet;
WebServer attn command; MainForm FAtten + SyncWebAttn; attSel.onchange in JS
- TUN mode: set_tun WebSocket command wired to ApplyTUN(); toneBtn toggles
with on/off highlight and pending protection; tuning field in state JSON
- FNP button opens semi-transparent filter overlay (10 buttons, 5×2 grid)
with mode-appropriate widths (SSB/CW/AM/FM); active filter highlighted;
cur.filter_bw updated immediately on click so passband redraws within 50ms

В non-DUP при MOX/TUN на возврате слышен и виден на водопаде хвост
своего сигнала. Во время TX RX-IQ оседал в RXA pipeline / FFT-истории
RX-анализатора и «выстреливал» при открытии гейта.
- WDSPEngine: KeepRXDuringTX (DUP-флаг). В non-DUP TX PushIQItemToDSP
дропает пакеты на входе DSP-потока — RXA и анализатор не кормятся.
- Windows-only post-TX hold (250 мс): дропаем И входящие RX-IQ, И аудио
в окне после MOX-off, чтобы скрыть «хвост» от FPGA TX-buffer/PA
slew-down радио. На Linux код-путь не активируется (буфер OS мелкий).
- Network: ClearDUCIQQueue + IsTransmitting guard в DUC sender thread,
чтобы недопереданные TX-IQ пакеты не уходили после MOX-off.

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.

The emulator (and real hardware) creates ddc_specific_thread (port 1025),
duc_specific_thread (port 1026), and rx_thread[0..3] (ports 1035+) only
after receiving HP Run=1. Previously ConfigureDDCs and SendDUCSpecific
were sent before SetRunAndFreq(True), so both packets arrived at closed
ports and were silently dropped — ddcenable remained -1, rx_thread slept
forever, no IQ data ever arrived, and the 5-second timeout fired Run=0.
Fix: reorder DoConnectDevice to send Run=1 first, then DDC/DUC Specific.
Also add keepalive resend of the cached DDC Specific packet every 500 ms
for the first 5 seconds after start, to handle thread-startup races on
real hardware over the network.
