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.

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
labeled lines, measureText-based labelMult to prevent overlap).

- Add LastCTun, LastAGCMode, LastAGCTop to TXvtrEntry; SaveCurrentBand
now captures all three in the XVTR branch; ActivateXvtrBand restores
them on slot switch/startup (previously CTun was always reset to False
and AGC was never saved/restored for XVTR)
- 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
from server on connect and mode change

- Fix web spectrum scroll resetting freq to XVTR minimum (same root
cause as desktop: hardcoded 60 MHz clamp; now delegates to server)
- Save/restore FM mode, NFM/WFM filter, squelch, CTCSS per XVTR slot
and per HF band (CTCSSOn/ToneIdx added to TBandSettings; full state
added to TXvtrEntry; ActivateXvtrBand restores all on slot switch)
- Fix UpdateFilterButtons always resetting NFM/WFM to default on
mode restore; now preserves saved filter index
- Add FM Step tuning: panel with STEP toggle + 6.25/12.5/20/25 kHz
selector (popup); mouse wheel uses selected step in FM mode;
state saved per band and XVTR slot

- LSB/USB: 5.0k–1.0k (unchanged)
- DSB: split into own group 16k–2.4k (was sharing AM filters)
- CWL/CWU: 1.0k 800 600 500 400 250 150 100 50 25 (removed 750, added 150)
- AM/SAM: 20k–5.0k (new wider range)
- Web FNP FM: now shows NFM/FM only (11k/16k), matching desktop
- Fix SyncWebFilter: FM array out-of-bounds; FFMDeviation now set on web filter select
- VfoOverlay: DSB separated from SSB with own quick-select values

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)
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- 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

- 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)

- Browser: AudioWorklet accumulates 960-sample frames, AudioEncoder encodes
to Opus, sends binary WS frame 'M' + raw Opus packet
- Server: opcode $02 handler decodes Opus via libopus, calls OnWebMic callback
- MainForm: WebOnMic converts PSingle→Double, pushes to PushTXMicSamplesD;
ApplyMOX switches mic source to txmsWeb when web client active, restores on TX-off
- WDSPEngine: added txmsWeb to TTXMicSource enum

Deadlock: BroadcastBinary held FClientLock during blocking SockSend;
slow/stalled client caused Stop() to wait forever. Fix: set SO_SNDTIMEO=1s
on each accepted socket so SockSend returns error instead of hanging,
mark client wsClosed on send failure so subsequent ticks skip it.
Mobile: move TONE/TX-slider/MOX to front of toolbar via CSS order so
they are immediately visible without horizontal scroll on phones.

Change filter passband fill from blue/white to semi-transparent red
on both spectrum and waterfall when transmitting or tuning, matching
the desktop behaviour.

Add 'dup' field to state JSON (FDisplayDuplex). In CTUN+non-DUP TX,
use vfo_a_hz as spectrum center so the TX signal renders at the VFO
position instead of the display center. In CTUN+DUP TX, keep center_hz
so the RX spectrum stays correctly positioned at the filter.

Track wheelActiveTs on each wheel tick; suppress server center_hz
overwrites for 300ms after last wheel event so localCenter stays at
the current VFO position instead of snapping back to screen center.
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.

- 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
