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.

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.

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.

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.
