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.

Add a per-operator toggle to hear your own downlink off the satellite
while transmitting (full-duplex self-monitor), and restrict QO-100-only
controls to the QO-100 mode.
- WDSPEngine: new MonitorRXDuringTX flag; audio gate becomes
`not FTXActive or (FKeepRXDuringTX and FMonitorRXDuringTX)` so RX audio
can pass to speakers during TX in full-duplex.
- Controller: FRxMuteOnTx (default True = mute RX on TX), SetRxMuteOnTx/
ApplyRxMuteToEngine, rfRxMuteOnTx notify; new InQO100 predicate
(Pluto + full-duplex XVTR slot) as the single gate for QO-100 UI.
- Settings: global RxMuteOnTx (rx_mute_on_tx, default True), persisted.
- MainForm: new RX MUTE button in TX panel next to DUP, visible only in
QO-100; BEACON button visibility tightened from "any transverter" to
InQO100 so it no longer shows in plain VHF/UHF modes.
- doc: plan updated (RF-AGC done, two temps, TX/RX locked split,
self-monitor, phase 6 done; remaining TODOs incl. web wiring).
Web intentionally left unchanged for now.

Pluto exposes two temperature sensors: the AD9361 transceiver
(ad9361-phy temp0/input, milli-°C) and the Zynq SoC/FPGA (xadc temp0,
raw+offset+scale → C = (raw+offset)*scale/1000). Only the former was
read. Now both are read and shown as "Temp 37/53C" (chip/SoC) in the
desktop status bar and web UI.
- ReadTelemetry gains an out SocTempC param (base + Pluto override);
Pluto reads xadc via the IIO context.
- Controller stores FLastPlutoSocTempC; SoC temp validated with a
plausibility window (no slew-limit — stable local sensor, unlike the
AD9361 sensor that spikes during mid-conversion).
- Status formatting handles one or both temps in MainForm and WebAdapter.
- Widen desktop status-bar field 3 (150→190) so both temps + RSSI fit;
web layout unchanged.

The PLL column (also used for QO-100 beacon status on Pluto) was
minmax(70px,90px), clipping "BCN LOCK 105Hz /7dB". Widen to
minmax(120px,185px), matching the desktop field-7 width. Frontend only.

Replace the single tracked-beacon line with a filter band spanning the
beacon width, split into two halves (left/right Manchester lobes at
±400 Hz) with a central divider (carrier null) and band edges at
±450 Hz, matching the desktop dec-marker width. Reference frequency is
now a green dashed line. Frontend only (WebPageHtml).

Mirror the desktop QO-100 beacon lock into the web interface and make it
work in the headless daemon.
Backend:
- WebServer: set_beacon/beacon_seed commands (+OnBeacon/OnBeaconSeed
events), beacon state fields, SetBeaconStatus, and beacon_visible/on/
text/ref_hz/track_hz in BuildStateJson. beacon_seed carries 'frac'
(0..1 click position); absolute Hz is computed controller-side from
live FCenterFreq/FSpanHz (mirrors desktop PixelToFreq).
- WebAdapter: OnBeacon->SetBeaconLock, OnBeaconSeed->BeaconSeedAtHz;
PushState mirrors compact status (matches MainForm.BeaconStatusText)
into the PLL status cell when visible (Pluto + active XVTR).
- MainForm/ewsdrd: wire the two callbacks.
- ewsdrd: call ServiceBeaconLock in the main loop @~10Hz (FRunning+
FWDSPReady gated). Without this the lock loop never ran headless.
Frontend (WebPageHtml):
- BCN button (visible only on Pluto+XVTR), highlighted while locked.
- Seed-on-mousedown with immediate return (like desktop FormMouseDown):
no drag/set_center so the gesture never moves the center / tears IQ.
Armed (first click after BCN) or Shift, mirroring desktop arm/Shift.
- PLL status cell shows beacon status (field-7 parity with desktop).
- Ref (green) + tracked (orange) beacon markers on spectrum/waterfall.
Known issue (unresolved): after lock the beacon can slowly drift off and
drop to "BCN sync". Suspected residual-sign anti-drift or retune-timing
on the web/daemon path; needs on-air diagnostics. See memory
project_web_beacon for the investigation state.

The headless daemon never set the web server's FreqMhzDigits, so it
stayed at the constructor default (3 = up to 999 MHz) and VHF/UHF/SHF
frequencies didn't fit the web VFO display. The GUI mirrors this per-
device setting in ApplyFreqMhzDigits; the daemon now does the same on
connect (rfDevice) via PushFreqDigits, reading the value the controller
loaded into FLoadedGlobal.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Fix: dragging/wheeling the spectrum in the web UI clamped frequency to a
hardcoded HF ceiling (vfoMax=60 MHz), so on Pluto VHF/UHF it snapped down
to 60 MHz and couldn't pan up (only the VFO wheel worked, via a different
limit). Push the backend's tuning range (BackendCaps.MinFreqHz/MaxFreqHz)
to the web alongside the band plan; JS vfoMin/vfoMax use freq_min/freq_max
from state. The transverter branch (XVTR_CUR>=0) is unchanged — it keeps
the wide-open range since the displayed RF freq is translated to IF and
clamped server-side.
Dead-code cleanup (audit of this session's work):
- SampleRateMode/TSampleRateMode: orphaned when the sample-rate
unification replaced the srmContinuous branch in ApplyBackendCapsToUI;
no readers left. Removed (+ now-unused PLUTO_MAX_SR).
- Pre-existing write-only/unused: TBackendCaps.MaxSampleRate,
SampleRateOverlay.SPAN_NAMES, MainForm.BAND_FREQ.

Web band selector was hardcoded to the HF plan, so on Pluto it showed
160m..6m instead of the VHF/UHF plan and highlighted the wrong entry
(band switching itself already worked: web sends idx, controller maps it
via the IsPluto plan). Mirror the sample-rate unification.
Single source of truth = BoardUtils -> controller:
- BoardUtils: TBandInfo/TBandPlanArray + BuildBandPlan(Pluto).
- TRadioController.BandPlan returns BuildBandPlan(IsPluto).
Both UIs derive from it:
- Desktop already plan-aware (RelabelBands + RestoreBand) - unchanged.
- Web: WebServer.SetBands + "bands" in state JSON; hosts push
BandPlan on connect/startup; JS builds the band selector from
state.bands (BAND_N/BAND_F now dynamic).

Sample-rate (span) presets were duplicated in three places and none was
authoritative: HPSDR set hardcoded in the desktop overlay (SPAN_RATES),
Pluto set in backend caps, and a separate hardcoded list in the web JS.
The web showed HPSDR rates even on Pluto, and the web adapter silently
dropped any rate outside a hardcoded HPSDR whitelist (so Pluto-only rates
like 960k/2304k never switched).
Single source of truth = backend caps -> controller:
- HPSDRNetwork.Caps now fills RatePresets [48k..1536k] (was nil).
- RadioBackend: named type TBackendRateArray.
- TRadioController.SampleRatePresets returns BackendCaps.RatePresets.
Both UIs derive from it:
- Desktop: ApplyBackendCapsToUI always feeds the overlay from
SampleRatePresets (overlay no longer owns the HPSDR list).
- Web: WebServer.SetRatePresets + rate_presets in state JSON; hosts
(daemon OnState/startup, GUI ApplyBackendCapsToUI/startup) push
SampleRatePresets; JS builds span buttons dynamically from it.
- WebAdapter.SyncSpan validates against SampleRatePresets instead of a
hardcoded whitelist, so any backend rate is accepted.

The headless daemon (ewsdrd) only ever built HPSDR devices, so Pluto
could not be used: backend is chosen by Dev.Kind and Pluto opens by URI,
neither of which the daemon propagated. Also local audio played on the
host and web Discover never probed network Plutos.
Shared, backend-agnostic helpers in TRadioController (used by GUI + daemon):
- ResolveDevice(IP): discovered->saved lookup restoring Kind/URI/Serial/
BoardType/MAC. MainForm.ResolveDevice now delegates here.
- AddSavedDevice(name, addr): web dev_add saves Pluto when addr has a URI
scheme (ip:/usb:/local:), else HPSDR. Both web hosts use it.
- SeedPlutoProbeFromSaved: seed network-probe URIs from saved Plutos
(no mDNS -> a network Pluto is only found by direct URI probe).
- LocalAudioEnabled flag (GUI=True): when False the local sound card is
neither opened nor written; RX audio goes only to web (OnAudioConsume).
DeviceStore.AutoStartDevice(out Dev): full autostart record (Kind/URI/
Serial) so a saved Pluto (URI-addressed, empty IPAddress on USB) can
autostart.
Daemon (ewsdrd.lpr): LocalAudioEnabled:=False; SyncConnect via
ResolveDevice; autostart via AutoStartDevice; SyncDiscover seeds probe
URIs then Discover; SyncDevAdd via AddSavedDevice.

Expose the QO-100 slot's LOError (Hz) on the QO-100 settings page,
placed right after LNB LO. Maps to Entries[QO100_SLOT].LOError — the
live LNB-drift calibration that the beacon lock folds its correction
into. Group height extended to 8 rows and the info label shifted down.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Replace the display-FFT centroid beacon lock with a decoder-based loop that
trims the active transverter's LOError from the beacon decoder's precise NCO
carrier estimate, compensating LNB drift so the whole downlink (incl. FT8)
stays put. Single BEACON button (lock = decoder). Also unifies the beacon
decoder filter marker between the CPU and OpenGL spectrum renderers.
Verified on air: lock holds, FT8 decodes cleanly.
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).

Replace the display-FFT centroid beacon lock with a decoder-based loop.
The beacon decoder already tracks the carrier precisely via its NCO
(squaring-FFT acquisition + Costas offload); its residual ResidHz+CarFreqHz
is an exact measurement of the beacon's offset from the aim point. Feed that
into LOError of the active transverter so the LO retunes to compensate LNB
drift — the whole downlink stays put, calibration persists.
RadioController:
- Remove MeasureBeaconFFT and all display-FFT lock state/constants
(lobe/search/track/slew/sym/shape/seed-gain/prom), fields
FBeaconManualSeed/FBeaconPromDB/FBeaconDecOn, methods
SetBeaconDecode/SetBeaconDecodeAtHz/BeaconDecodeEnabled.
- SetBeaconLock is now the master switch (lock = decoder); BeaconSeedAtHz
aims the decoder; ServiceBeaconLock measures beacon freq from the decoder
scope and trims LOError (gain 0.5, deadband 20 Hz, step clamp 400 Hz,
settle 8 ticks). Feed-forward of the aim keeps the decoder locked through
the retune (net baseband ~0). Lock/SNR now come from the decoder.
MainForm: single BEACON button — left-click toggles lock (+ opens the
constellation/bulletin scope, arms the spectrum click for aiming),
right-click shows/hides the scope. Spectrum click (armed or Shift) aims via
BeaconSeedAtHz. Simplified status field and markers.
Both targets build (lazbuild --ws=qt6 + build-ewsdrd.sh). Not yet verified
on air. Risk: BEACON_RESID_SIGN=+1.0 — flip to -1.0 if the loop runs away.

After successful on-air validation, drop the temporary diagnostics:
- IQ baseband dump to ~/ewsdr_beacon_iq.f32 (FDbgStream/DbgWrite2).
- BeaconLog file logger (~/ewsdr_beacon.log) and per-second STATE / AIM lines.
- Dead Gardner timing fields (FMidI/FMidQ/FHalf/FPrevI/FPrevQ), superseded by
the ML signal×slope TED.

Decode and show the AO-40 frame payload as text in the beacon scope window.
- RadioController.GetBeaconFrame exposes the latest 256-byte frame.
- BeaconScopeForm: poll the frame counter; on each new frame, parse the
payload (drop trailing 2-byte CRC, printable ASCII, 64-char lines, as in
gr-satellites qo100.parse) and append to a scrolling read-only memo.
- Window widened/heightened; constellation size capped to leave room.
Frame format verified offline against a real on-air capture: the decoder
produces the live QO-100 AMSAT bulletin text (RS errors=0).

Full chain now decodes the QO-100 central beacon to 256-byte AO-40 frames
on-air (frames>0, RS errors=0). Builds on M1 (stable BPSK demod).
FEC backend (BeaconFEC.pas, TBeaconFEC):
- AO-40 FEC: distributed sync (65 bit, step 80) -> 80x65 deinterleave ->
Viterbi r=1/2 k=7 -> CCSDS descramble -> 2x RS(160,128). Links system
libfec (Karn) load-time (libfec.so/.dll/.dylib). Viterbi AO-40 [0x4F,-0x6D]
remapped to libfec [0x6D,0x4F]. Validated against gr-satellites reference
vectors (fectest2: exact 256-byte frame, 0 mismatches).
DBPSK Manchester frontend (BeaconDecoder.pas):
- Chip-rate (800) processing: RRC matched filter -> ML signal-times-slope
timing recovery -> Costas -> Manchester combine (block phase select) ->
differential decode -> soft symbols to FEC.
- Carrier acquisition: squaring-FFT estimates the residual (carrier at +-pi/chip
defeats decision-directed Costas), one-shot pulls it to DC via residual NCO.
- Costas frequency offload into pre-RRC NCO (with deadband) tracks LNB drift
without hitting the +-pi Costas clamp.
- ML TED replaces Gardner, which degenerates on the Manchester chip stream.
Temporary on-air diagnostics retained (IQ dump + STATE log) pending wider
signal validation; to be removed before final cleanup.

The DUP toggle wrote FDisplayDuplex directly, bypassing the controller's
SetDuplex (which also sets KeepRXDuringTX live and fires rfDuplex). And
MainForm had no rfDuplex render case, so QO-100 auto-enabling duplex
(ActivateXvtr → SetDuplex) left the button unlit while FDisplayDuplex=True
— pressing DUP then turned it OFF when the user expected ON.
Single path now: ApplyDUP just calls SetDuplex; a new rfDuplex render case
styles the button and (when transmitting) switches the display source.
Both the button and QO-100 auto-enable go through it, so the button always
reflects state and KeepRXDuringTX stays in sync.

Document the TX-path work landed this session:
- §4.6: polyphase FIR interpolator + sample-rate-scaled TX buffer +
SoapyPlutoSDR confirmation of 32768 full-scale.
- §4.8 (new): power-linear drive→atten mapping, full WDSP digital level,
TX LO powerdown gated by PTT.
- Phase 4 status updated.
- Related fixes: per-band FM settings (SQL/CTCSS/step/repeater) restore on
startup — was dropped by LoadDevice; affects all backends.

TX LO (altvoltage1) is now powered down on RX and enabled on PTT, instead
of staying on continuously. Removes the TX carrier leakage that showed up
at the VFO frequency in the RX spectrum (and persisted after MOX), and
stops idle TX-LO radiation. ApplyTxLO sets powerdown from FTransmitting,
which also recovers the LO if external software (e.g. SDR Console) left it
powered down. RX LO (altvoltage0) is kept on — receive is continuous; QO-100
full-duplex still works (RX LO separate).
Trade-off: re-enabling the TX LO re-runs the AD9361 synth calibration
(a few ms), so the first syllable on SSB may be slightly clipped.

LoadDevice (bulk startup band loader) parsed only freq/mode/filter/AGC/
CTun/center/span and skipped the FM fields, while SaveBand writes them and
LoadBand reads them. So FM squelch, CTCSS, step and repeater shift were
saved on exit but reset to defaults on the next start (band switching kept
working — that path goes through the in-memory band cache, not disk).
Added the missing fmsq_on/fmsq_level/ctcss_on/ctcss_idx/fmstep_on/
fmstep_idx/fmrpt_dir/fmrpt_offset reads to LoadDevice, mirroring LoadBand.
Affects all backends, not just Pluto.

TUN produced no tone: TUNLevel default 10% mapped via the old dB-linear
attenuation curve (−89.75..ceiling) to −81.8 dB → effectively off. Now
power-linear: dB = ceiling + 20*log10(pct/100), so 10%→−30, 50%→−16,
100%→ceiling — usable across the whole slider.
Also keep WDSP digital level at full-scale for Pluto (ApplyWDSPDrive):
power is set once via hardware attenuation, not by scaling the WDSP path.
HPSDR unchanged (drive byte still drives the radio PA).
Note: at a given slider position Pluto TX is now much hotter than before
(50%: −49.9→−16 dB). Ceiling stays PlutoTxMaxAttDb (default −10 dB).

Replaced linear interpolation upsampling (192k→device-rate) with a
polyphase FIR interpolator ×L. Prototype: windowed-sinc lowpass (Blackman,
~-58 dB sidelobes), TAPS*L long, cutoff TX_FIR_CUT=40k, normalized to unity
per-phase DC gain (loudness unchanged). Images at multiples of 192k are now
suppressed ~-58 dB instead of only sinc², cleaning up the uplink spectrum.
BuildTxResampler designs coefficients per FTxRatio in StartTX; FTxDlI/Q
delay line persists across SendDUCIQ calls, reset on StartTX/ClearDUCIQQueue.
Removed FTxPrevI/Q.

Fixed 4096-pair TX buffer was too small for full-duplex above ~1 Msps
("not enough ... samples getting dropped" per SoapyPlutoSDR), causing
clicks/dropouts. Now sized as round(rate/60) rounded up to a power of 2,
clamped [4096..65536] (576k→16384, 1536k→32768). FIFO cushion (~4 buffers)
resizes to match in StartTX.

QO-100 reuses the transverter path (VFO/band-stack/beacon-lock untouched)
with a split LO for the geostationary transponder:
- TXvtrEntry += FullDuplexTx + TxLOOffset (persisted). Reserve the last
XVTR slot (QO100_SLOT) for QO-100; migration restores the template when
the slot is unset or has empty offsets (fixes old configs showing zeros).
- XvtrTranslateTX: TX LO = visible - TxLOOffset (no LNB LOError) for QO-100;
identical to RX translate for normal transverters. Switched all TX-side
translate calls (controller + MainForm).
- SetDuplex wired (live KeepRXDuringTX); auto display-duplex on QO-100 entry.
- New "QO-100" settings page (LNB LO / transponder offset / downlink edges /
RX gain / TX ceiling + live RX-IF/TX readout); QO slot hidden from the
transverter table. Reuses OnXvtrChange — no MainForm wiring needed.
- doc/PLUTO_INTEGRATION_PLAN.md: phase 5 done.
Builds clean (headless + qt6 GUI). Not yet verified on hardware.

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.

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.

Add ADALM-Pluto / AD9361 support as a second hardware backend alongside
openHPSDR, sharing the WDSP DSP pipeline and the existing controller API

- 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.

Three runtime fixes found testing the daemon on real hardware:
- WDSP opened in ~47s (vs <1s GUI): WDSPEngine.Open never imports FFTW wisdom;
the GUI does it separately in EnsureWDSPWisdom before Open. Daemon now calls
WDSPwisdom(GetAppCfgDir) before Open (imports the existing wdspWisdom00 in ms;
builds it once if absent). Verified: open is now instant.
- Web waterfall/spectrum filled only the left ~6%: the analyzer's pixel width
defaults to DISPLAY_BLOCK_SIZE (64). The GUI calls SetSpectrumWidth(panel) every
tick; headless never did, so only 64 of the 1024 web buffer points had data.
Daemon now calls SetSpectrumWidth(1024) after Open (== SPECTRUM_PIXELS / web
buffer). FLastSpectrumW survives channel recreation.
- SIGINT during the (blocking) autostart connect was lost because Run set
FRunning:=True *after* the connect, overwriting RequestStop. Set FRunning:=True
before autostart so a stop during connect exits the loop.

GetAppConfigDir derives the dir from ApplicationName, which defaulted to the
binary name 'ewsdrd' -> a separate empty ~/.config/ewsdrd/. With no per-device
settings the daemon never configured WDSP's FFT/spectrum/waterfall display (web
showed a white waterfall and no spectrum), never resolved a saved board type
(Board=0), and -- critically -- found no FFTW wisdom, so WDSP recomputed it from
scratch on Open (~48s vs <1s in the GUI). Set OnGetApplicationName := 'EWSDR'
(matching the GUI's Application.Title) before constructing the controller, so the
daemon reads the same ~/.config/EWSDR/ (settings, saved devices, wdspWisdom00).

ewsdrd.lpr — a console daemon that runs TRadioController + TWebAdapter WITHOUT
TMainForm/LCL, proving the Phase-5 goal: web-only headless operation. THeadlessHost
wires the data-path callbacks to the controller, the web command handlers to the
adapter (lifecycle ones marshalled to the main thread via FCtrl.Invoke =
TThread.Synchronize), opens WDSP synchronously, autostarts the saved device, and
runs a CheckSynchronize + periodic PushState loop. SIGINT/SIGTERM → graceful
StopAndDisconnect (persist + Run=0).
To keep the controller graph truly LCL-free, PlatformUtils now guards its only
Forms dependency (Screen.PixelsPerInch in CurrentScreenDPI) behind {$IFNDEF
HEADLESS}; the GUI build is byte-identical (HEADLESS undefined). build-ewsdrd.sh
compiles the headless graph from source with -Mobjfpc (nested comments) -dHEADLESS
into a separate lib-headless/ output dir, untouching the GUI .ppu.
Verified: builds clean; runs headless, web server up (HTTP 401 = serving), no LCL;
SIGINT shuts down gracefully. Radio-connect + web round-trip need hardware to test.

ConnectAndRun (ConnectDevice + RestoreBand + XVTR restore + active-VFO retune +
StartRunning) and StopAndDisconnect (StopRunning + settings persist + Disconnect)
move into TRadioController, making the full connect/disconnect lifecycle callable
headless. MainForm.DoConnectDevice/DoStopAndDisconnect become thin wrappers that
only add UI-extras (status strings, AGCTop mirror, spectrum reset/resize,
offline status, A-VFO highlight). Behavior-preserving: status/highlight now run
after bring-up, consistent with the batch-29 precedent (no packets yet, safe).

OnSpectrumReady/OnWaterfallReady move into TRadioController. The controller now
owns the last spectrum/waterfall frame (FSpectrumBuf/FWaterfallBuf) for the web
mirror and emits raw pixels via OnSpectrumData/OnWaterfallData. MainForm
subscribes for FSpecView rendering (+ waterfall scroll decimation, a UI concern).
TWebAdapter.PushState now reads the frame from the controller (no buffer params).
Behavior-preserving; removes the last spectrum/waterfall data-path coupling.

OnAudioReady moves from MainForm into TRadioController (radio-speaker push +
local AudioOut). The web steal becomes a route hook: controller fires
OnAudioConsume; TWebAdapter.AudioConsume mixes to mono and pushes to the web
client, returning True to skip local AudioOut. Behavior-preserving; removes the
last audio-path coupling to MainForm.

CAT becomes a peer adapter over the controller, alongside WebAdapter. TCATAdapter
owns the CAT engine + serial/TCP transports and builds the TCATContext: getters
read FController directly (CAT thread), setters/commands call controller commands
marshaled via FController.Invoke. No MainForm or WebAdapter dependency — the
historical CAT->WebAdapter.OnXxx coupling (Mode/AGC/Band/etc.) is gone; CAT talks
only to the controller.
MainForm keeps CAT *settings* (FCATLastGlobal + OnCATSettingsChange + SettingsForm
wiring), now calling FCATAdapter.ApplySettings on change/connect. Removed
InitCATEngine, CATApplySettings, all CATGet*/CATSet*/CATDo*/SyncCAT* and the
FCATEngine/FCATSerial/FCATTcp/FCATSyncFreq fields.
Fixes a latent bug: CATSetFilterIdx routed a filter index through the web BW handler
as a negative-encoded value, but that branch was dead since batch 21 — CAT now calls
FController.SetFilterIdx directly. Adds StoreVfoA (store VFO A without retune when B
is active) and uses the now-real SetBand/BandUp/BandDown/TuneActiveBy commands.

SetBand was a skeleton (FCurrentBand := Idx + Changed), leaving BandUp/BandDown
non-functional. Fill it with the band-change logic (XVTR-exit + persist + restore)
that WebAdapter.SyncBand had inline; SyncBand now just calls FController.SetBand.
Gives CAT band up/down/by-index a controller command to call (Phase 4) instead of
routing through the web adapter.
