- Status bar / web now show Pluto/LibreSDR model + serial instead of
"Unknown Board" (BoardDisplayName in controller; UI just renders it).
- Field 3 shows AD936x chip temperature + RX RSSI for Pluto (no PA →
Supply only for openHPSDR). Polled via backend.ReadTelemetry (~2 Hz),
filtered for sensor glitches (plausibility window + slew-limit, with
anti-stick) — fixes rare bogus -15°C readings.
- Add libiio binding iio_channel_attr_read_double.
- Remove stale root pluto_integration.MD (superseded by
doc/PLUTO_INTEGRATION_PLAN.md).

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.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
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.

CTun position was lost on band restore / restart, and VHF/UHF bands were
never saved on Pluto.
- SaveCurrentBand: the >61 MHz guard (HPSDR HF-only) skipped saving native
Pluto VHF/UHF bands → 2m/70cm reverted to defaults. Now HPSDR-only; Pluto
saves VU-plan bands (FreqToBandIdx guards cross-band pollution).
- Persist DDC center for CTun: new TBandSettings.CenterHz (+ JSON center_hz)
and TXvtrEntry.LastCenterHz (+ last_center_hz). RestoreBand / ActivateXvtr
restore the saved center when CTun is on and the offset fits the span,
instead of forcing center := VFO (which re-centered the receiver).
- UpdateFreqDisplayMax: freq-display upper bound from active transverter's
FreqEnd (lets QO-100 show 10 GHz past the 6 GHz Pluto cap).
- QO-100 transverter template (slot 2, disabled): downlink 10489.5–10490.0,
LO 9750. MigrateXvtrTemplate injects it into the first free slot for
devices that already have a saved xvtr config (template was otherwise
masked by the loaded slots).

- RX hw-gain (Pluto/AD936x): backend SetRxGain(ModeIdx, GainDb) — gain_control_mode
(manual/fast_attack/slow_attack/hybrid) + hardwaregain. Controller FRxGainMode/
FRxGainDb, commands SetRxGainMode/SetRxGain/RxGainBy, rfRxGain event, snapshot,
applied in StartRunning. Persisted per-device (rx_gain_mode/rx_gain_db). HPSDR
unaffected (backend no-op).
- UI: separate "RF AGC" panel below the (unchanged) WDSP AGC block, shown only for
Pluto — FAST/SLOW/HYB/MAN mode buttons + manual GAIN slider. LayoutLeftPanel
reflows lower panels via RelayoutBelowBands; no layout shift on HPSDR.
- Cold-init fix: direct sampling_frequency write doesn't load the AD9361 FIR
decimation filter, so a cold-booted Pluto showed a wide centre spike that didn't
track tuning (worked only after SDR Console pre-initialised it). Add optional
libad9361 binding (dynamic) and call ad9361_set_bb_rate() in ApplySampleRate,
which configures BBPLL + loads the FIR; falls back to direct write if absent.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Add ADALM-Pluto / AD9361 support as a second hardware backend alongside
openHPSDR, sharing the WDSP DSP pipeline and the existing controller API
(UI stays decoupled from logic).
- RadioBackend.pas: abstract TRadioBackend + TBackendCaps + TRadioDevice
(Kind/URI/Serial). THPSDRNetwork now derives from it (state via virtual
getters); TRadioController.FNetwork is the base type.
- IIOBindings.pas: dynamic libiio loader (runs without libiio present).
- PlutoBackend.pas: scan/probe-by-URI, connect, LO/rate/bandwidth/gain
control, RX streaming thread (int16->24bit BE -> OnDDCIQ), Q conjugated
to match WDSP IQ convention. Verified on LibreSDR (AD9361) over network.
- Unified discovery: TDiscoverThread scans both backends; network Plutos
found via direct ProbeURI (no mDNS needed). ConnectDevice dispatches by
Dev.Kind (EnsureBackend swaps backend, preserving callbacks).
- DeviceStore/DeviceForm: persist Kind/URI/Serial; save Pluto via
AddSavedPluto so saved/autostart devices reconnect across restarts.
- VHF/UHF band plan (BoardUtils, kind-aware): 6m..ADS-B for Pluto; fixes
HF clamps (band detect, mouse-wheel 60 MHz cap, freq-display max).
- SampleRateOverlay: configurable presets (Pluto 576k..5760k, >520 ksps),
auto-width to fit.

FLastSMeter is sourced from WDSP (GetSMeterDBm), not the network HP-status,
so only the GUI timer (MainForm) ever updated it. In headless mode nothing
did, leaving PushState to send web clients a frozen -130 dBm. Refresh it in
the daemon Run loop before each PushState, mirroring the GUI timer.

1. StartRunning applied AGC mode via a raw enum cast (TWDSPAGCMode(FAGCMode))
instead of the index→enum table, inverting Fast↔Off on every connect/go-live
(GUI and daemon). Now uses ApplyAGCToEngine like the rest of the unit.
2. SetFilterIdx indexed the per-mode BW/deviation tables with an unchecked Idx
(FM tables hold only 2 entries) — out-of-bounds when driven from CAT/web.
Now clamps Idx per mode (EnsureRange).
3. ConnectDevice loaded FActiveVfo / FCurrentBand straight from config without
range validation; a corrupt/old blob could leave FCurrentBand invalid and
make later SetMode/SetFilterIdx write past FBandCache. Both now clamped.
4. VfoSwap did not run the bandstack DSP restore that SetActiveVfo does, so a
swap to a VFO on another band kept the old mode/filter/AGC while the band
button highlighted the new band. Now mirrors SetActiveVfo.

- 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
panels: AGC, SQL, CTCSS, STEP were inconsistent
- 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
masks FPU exceptions globally).

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.

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

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

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

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

Was 72px, causing VFO to disappear while there was still visible space
between it and the S-meter. Now 8px — just enough visual breathing room.

- RelayoutBelowBands: replace hardcoded Inc(Y,76) with actual panel
heights so Mode/Filter/RX panels don't overlap at scaled DPI
- ResizeSpectrumPanels, SplitterMouseMove/Up: make RULER_H dynamic
via MulDiv(18, Screen.PixelsPerInch, 96) so frequency ruler is tall
enough to fit text at 125%/150% DPI
- LayoutTopVfoBlock: use BtnTopVfoASelect.Width / BtnTopVfoBSelect.Width
instead of constant VFO_BTN_W so FreqDisp doesn't clip the A/TX buttons

Replaced the WF AGC and WF NF toggle buttons in the main panel with
"Waterfall AGC" and "Waterfall NF" checkboxes in the Settings form
Waterfall tab (AGC & Noise Floor group). Settings are global, defaults
remain AGC=on, NF=off.

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)

- WebServer: add fwd_w, swr, pa_max_power to state JSON and PushSpectrum
- MainForm: pass FLastFwdW, FLastSWR, FPAMaxPower to PushSpectrum
- Web UI: paintSM switches to paintTXMeter when transmitting/tuning;
same layout as desktop — two sub-bars at 44-58% height, power ticks
above, SWR ticks below, SWR>2.5 turns red with "SWR High" label

- 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)
