Fix wrong VIS codes for PD90 (96→99), PD120 (93→95), PD180 (95→97),
PD240 (113→96), and ScottieDX (55→76). This caused PD180 to be detected
as PD90 and PD120 to fail entirely.
Replace batch Goertzel pixel decoding with analytic signal (Hilbert
transform) FM demodulation. The Goertzel approach used 96-sample windows
with ~500 Hz resolution — wider than the 800 Hz pixel frequency range —
making accurate pixel decoding impossible for fast modes like Martin2
and Scottie2. The Hilbert method computes per-sample instantaneous
frequency, matching the approach used by QSSTV and other professional
SSTV decoders.

Tolerate intermittent ambiguous windows during leader detection (up to
3 consecutive misses), use energy-based break detection when tone
classification fails at leader-break boundary, and add single-bit VIS
error correction for parity-bit and data-bit corruption on noisy HF.

The box-drawing character filter was dropping ANY line containing │ or ─,
including dsd-fme data lines that use these as column separators (e.g.
"DMR BS │ Slot 1 │ TG: 12345 │ SRC: 67890"). Now only filters lines
that are purely decorative (no alphanumeric content).
Also adds -J /dev/stderr so dsd-fme writes its event log to stderr
where we capture it, and debug logging of raw stderr lines.

-fd means D-STAR in dsd-fme, not DMR — causing sync detection
(shared C4FM modulation) but no decoded data. DMR Simplex is -fs.
Also fix -o - (invalid in dsd-fme) to -o null for headless servers,
add D-STAR flag mapping, and handle TGT/SRC output format in parser.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
dsd-fme remapped several flags from classic DSD: -fp is ProVoice (not
P25), -fi is NXDN48 (not D-Star), -fv doesn't exist. This caused P25
to trigger ProVoice decoding and D-Star to trigger NXDN48. Corrected
flag table and added C4FM modulation hints for better sync reliability.
Also fixes: device panel showing "DMR" regardless of protocol, signal
activity status flip-flopping between LISTENING and IDLE, and rtl_fm
squelch chopping the bitstream mid-frame. Adds PPM correction and
relax CRC controls for fine-tuning on marginal signals.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The _DSD_FME_PROTOCOL_FLAGS dictionary had every protocol flag wrong,
causing dsd-fme (the preferred binary) to receive invalid or mismatched
-f flags. Also fix orphaned process leak on startup failure and add
centralized input validation for frequency/gain/device.

Remove all GSM cellular intelligence features including tower scanning,
signal monitoring, rogue detection, crowd density analysis, and
OpenCellID integration across routes, templates, utils, tests, and
build configuration.

The EGSM900 band table had start=925e6 but ARFCNs 0-124 use downlink
frequencies starting at 935 MHz (DL = 935 + 0.2*ARFCN). The 925 MHz
value is the E-GSM extension band (ARFCNs 975-1023).
This caused grgsm_livemon to tune 10 MHz too low — ARFCN 22 tuned to
929.4 MHz instead of 939.4 MHz, receiving no GSM frames and producing
zero GSMTAP packets for tshark to capture.
Also adds EGSM900_EXT band (ARFCNs 975-1023, DL 925.2-934.8 MHz)
and diagnostic logging in the monitor thread to track raw tshark
line counts vs parsed packets.

- /lookup_cell and /detect_rogue rejected CID=0 towers because
`all([..., cid])` is falsy when cid=0; use `is not None` checks
- can_use_api() now returns False when GSM_OPENCELLID_API_KEY is empty,
preventing the geocoding worker from wasting daily quota on doomed calls
- /lookup_cell returns 503 with clear message when API key not configured
- parse_tshark_output uses rstrip('\n\r') instead of strip() to preserve
leading empty tab-separated fields (strip() ate leading tabs, shifting
all columns when the first field was empty)

CID=0 with valid MCC/MNC means the scanner found the cell but didn't
decode System Information 3/4 (which carries the Cell ID). These are
still valid towers worth displaying. Only filter when MCC=0 AND MNC=0
(truly unidentified signals).
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Backend:
- Filter out CID=0 and MCC=0 entries (ARFCNs with no decoded cell identity)
Frontend:
- Move stats update before coordinate check so towers always counted
- Fix signal_strength display using null check instead of || (0 is falsy)
- Show operator name, frequency, and status in tower detail panel
- Show "Located" indicator in tower list for geocoded towers
- Fix selectTower crash when tower has no coordinates
- Update placeholder text to "Select a tower from the list"
- Add try/catch to selectTower for error resilience
Tests:
- Add tests for CID=0 and MCC=0 filtering

Parser expected pipe-delimited table rows but grgsm_scanner outputs
comma-separated key-value pairs like:
ARFCN: 975, Freq: 925.2M, CID: 13522, LAC: 38722, MCC: 262, MNC: 1, Pwr: -58
This was the root cause of no data appearing in GSM Spy.

Replace the batch rtl_power SSE pipeline with continuous I/Q streaming
via WebSocket for smooth ~25fps waterfall display. The server captures
raw I/Q samples (rtl_sdr/rx_sdr), computes Hann-windowed FFT, and
sends compact binary frames (1035 bytes vs ~15KB JSON, 93% reduction).
Client falls back to existing SSE path if WebSocket is unavailable.

The DSD stderr parser had regex ordering bugs that swallowed voice and
call events as bare slot events, and only matched classic dsd output
format (not dsd-fme). Unmatched lines were silently dropped, leaving
the signal activity panel with nothing to display.
- Reorder regex checks: TG/Src before voice before slot
- Support dsd-fme comma-separated format (TG: x, Src: y)
- Make bare slot regex strict (only standalone "Slot N" lines)
- Forward unmatched DSD lines as raw events for diagnostics
- Add LISTENING state to signal activity panel for raw output
- Show raw decoder output text below synthesizer canvas
- Fix test mocks for find_dsd() tuple return value

slowrx is a GTK GUI app that doesn't support CLI usage, so the SSTV
decoder was silently failing. This replaces it with a pure Python
implementation using numpy and Pillow that supports Robot36/72,
Martin1/2, Scottie1/2, and PD120/180 modes via VIS header auto-detection.
Key implementation details:
- Generalized Goertzel (DTFT) for exact-frequency tone detection
- Vectorized batch Goertzel for real-time pixel decoding performance
- Overlapping analysis windows for short-window frequency estimation
- VIS header detection state machine with parity validation
- Per-line sync re-synchronization for drift tolerance

Introduces an 'optionals' dependency group in pyproject.toml. There was a discrepancy because they had been added to requirements.txt at some point during the last few commits but not to .toml. Update on test_requirements.py to include and validate these optional dependencies. Enhances test logic to ensure all main, dev, and optional dependencies are checked for environment consistency.
Add support for connecting to Meshtastic LoRa mesh devices via USB/Serial.
