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

- Send all existing towers on SSE connect (fixes data loss on reconnect)
- Fix tower.signal -> tower.signal_strength field name in frontend
- Fix TypeError crash in selectTower when tower has no coordinates
- Add Connection: keep-alive header to SSE response
- Add comprehensive console.log debugging for SSE data flow
- Handle error/disconnected SSE event types in frontend

grgsm_scanner is a Python/GNU Radio script, so stdbuf has no effect.
Setting PYTHONUNBUFFERED=1 in the subprocess env forces Python to
flush stdout on every write, enabling real-time scan output.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
grgsm_scanner fully buffers stdout when piped, so scan results never
reach Python until the buffer fills or process exits. Wrapping with
stdbuf -oL forces line-buffered output for real-time data streaming.
Also increased scan timeout from 120s to 300s since scanning 4 bands
legitimately takes 2-3 minutes.

The ptrkrysik/gr-gsm repo uses SWIG which is incompatible with
GNU Radio 3.10+. The bkerler fork supports modern GNU Radio and
builds successfully on current Ubuntu/Debian systems.
Updated all references in Dockerfile, setup.sh, dependencies.py,
and error messages.

apt-packaged gr-gsm aborts with SIGABRT (-6) due to duplicate FSM
registration in libosmocore. Setting this env var suppresses the
fatal assertion, allowing grgsm_scanner to run normally.
Applied to both scanner and livemon subprocess spawns.

grgsm_scanner exits in <300ms with osmo_fsm assertion error due to
libosmocore incompatibility. Added crash detection: if process exits
in <5s with non-zero code, counts as crash. After 3 crashes, stops
retrying and sends error to SSE stream so the UI can display it.
Also drains remaining queue items after process exits and logs exit
code and scan duration for diagnostics.

Global LOG_LEVEL defaults to WARNING, silencing all INFO/DEBUG logs.
GSM Spy needs verbose logging for scanner diagnostics. Override the
module logger level to DEBUG so scanner output is always visible.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
gsm_spy.py used logging.getLogger() directly which returns a bare
logger with no handler. The parent 'intercept' logger has
propagate=False, so all GSM Spy logs were silently dropped.
Now uses utils.logging.get_logger() which adds a stderr handler
and sets the log level, matching all other route modules.

grgsm_scanner (like many GNU Radio tools) writes scan results to
stderr, not stdout. The stderr reader was only logging at debug
level and discarding lines. Now feeds stderr into the parse queue.
Also added info-level logging for all scanner output lines to aid
debugging.

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.

stop_scanner() cleared gsm_spy_active_device without calling
release_sdr_device(), so the device stayed claimed in the registry.
The scanner thread's finally block then saw None and skipped release.

GSM Spy was failing with FileNotFoundError because grgsm_scanner
wasn't installed. These tools are now installed automatically by
setup.sh (both Debian and macOS) and included in the Dockerfile,
matching how other tools like multimon-ng and ffmpeg are handled.
- setup.sh: Remove ask_yes_no prompts for gr-gsm and tshark, install
unconditionally; add check_recommended tier for final summary
- Dockerfile: Add tshark to apt layer, add gr-gsm RUN layer with
apt-then-source-build fallback, preseed debconf for tshark
- gsm_spy.py: Add shutil.which pre-check in start_scanner route,
catch FileNotFoundError in scanner_thread to stop retry loop

- kill_all() now resets gsm_spy_scanner_running and related state so
the scanner thread stops after killall
- scanner_thread sets flag to False instead of None on exit
- Restore alert_rules, alert_events, recording_sessions tables and
wifi_clients column removed by PR in database.py
- Escape all server-sourced values in analysis modals with escapeHtml()
- Reset gsm_towers_found/gsm_devices_tracked on stop to prevent
counter drift across sessions
- Replace raw terminate/kill with safe_terminate() in scanner_thread

Move waterfall controls from the sidebar into a function-strip bar inside
#listeningPostVisuals so they sit directly above the waterfall canvas.
Also fix the "SDR device in use" error when clicking a waterfall frequency
to listen — the WebSocket waterfall's device claim wasn't being released
before the audio start request because the backend cleanup hadn't finished.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Zooming caused "I/Q capture process exited immediately" because the client
closed the WebSocket and opened a new one, racing with the old rtl_sdr
process releasing the USB device. Now zoom/retune sends a start command on
the existing WebSocket, and the server adds a USB release delay plus retry
loop when restarting capture within the same connection.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
After a WebSocket handler exits, flask-sock returns a Response to
Werkzeug which writes "HTTP/1.1 200 OK..." on the still-open socket.
Browsers see these HTTP bytes as a malformed WebSocket frame, causing
"Invalid frame header".
Now the handler explicitly closes the raw TCP socket after the
WebSocket close handshake, so Werkzeug's write harmlessly fails.
Applied to both waterfall and audio WebSocket handlers.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
simple-websocket 1.1.0's receive(timeout=N) returns None on timeout
instead of raising TimeoutError. The handler treated None as
"connection closed" and broke out of the loop, causing Werkzeug to
write its HTTP 200 response on the still-open WebSocket socket.
The browser saw those HTTP bytes as an invalid WebSocket frame.
Now checks ws.connected to distinguish timeout (None + connected)
from actual close (None + not connected).

agents.js syncLocalModeStates() expects these endpoints to check
whether each mode is running locally. Both were missing, causing

The fft_reader thread was calling ws.send() concurrently with
ws.receive() in the main loop. simple-websocket is not thread-safe
for simultaneous read/write, corrupting frame headers. Now the reader
thread enqueues frames and only the main loop touches the WebSocket.

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.

Reverts IQ pipeline and removes syncWaterfallToFrequency calls from
pager, sensor, rtlamr, DMR, SSTV, and SSTV general modes. Waterfall

Replace rtl_fm/rtl_433 with rtl_sdr for raw IQ capture when available,
enabling a Python IQ processor to compute FFT for the waterfall while
simultaneously feeding decoded data to multimon-ng (pager) or rtl_433
(sensor). Falls back to the legacy pipeline when rtl_sdr is unavailable.

1. utils/weather_sat.py — Added delete_all_images() method that globs for *.png, *.jpg, *.jpeg in the output dir, unlinks each, clears _images list, and returns the
count.
2. routes/weather_sat.py — Added DELETE /weather-sat/images route that calls decoder.delete_all_images() and returns {'status': 'ok', 'deleted': count}.
3. static/js/modes/weather-satellite.js:
- Added currentModalFilename state variable
- renderGallery() now sorts images by timestamp descending, groups by date using toLocaleDateString(), renders date headers spanning the grid, and adds a delete
overlay button on each card
- showImage() accepts a filename param, stores it in currentModalFilename, and creates a modal toolbar with a delete button
- Added deleteImage(filename) — confirm dialog → DELETE /weather-sat/images/{filename} → filter from array → re-render + close modal
- Added deleteAllImages() — confirm dialog → DELETE /weather-sat/images → clear array → re-render
- Exposed deleteImage, deleteAllImages, and _getModalFilename in public API
4. static/css/modes/weather-satellite.css:
- Added position: relative to .wxsat-image-card
- .wxsat-image-actions — absolute top-right overlay, hidden by default, appears on card hover
- .wxsat-image-actions button — dark background, turns red on hover
- .wxsat-date-header — full-grid-width date separator with dimmed uppercase text
- .wxsat-modal-toolbar — absolute top-left in modal for the delete button
- .wxsat-modal-btn.delete — turns red on hover
- .wxsat-gallery-clear-btn — subtle icon button, pushed right via margin-left: auto, turns red on hover
- Updated .wxsat-gallery-header from justify-content: space-between to gap: 8px for proper 3-child layout
5. templates/index.html — Added clear-all trash button with SVG icon in the gallery header, wired to WeatherSat.deleteAllImages().
Merges upstream changes into fork while preserving weather satellite
(NOAA APT/Meteor LRPT via SatDump), rtlamr, multi-arch build, and
decoder console features from our branch.

- Kill audio pipeline when startup produces no data instead of leaving
zombie processes running
- Skip unnecessary 1s USB release delay when no processes were active

Stream threads for sensor, pager, acars, rtlamr, dmr, and dsc modes
never called release_sdr_device() when their SDR process crashed,
leaving devices permanently locked in the registry. Also fixes orphaned
companion processes (rtl_fm, rtl_tcp) not being killed on crash, start
path failures leaking processes, DMR stop handler missing lock, and
listening post/audio websocket pkill nuking all system-wide rtl_fm
processes. Wires up register_process()/unregister_process() so the
atexit/signal cleanup safety net actually works, and adds rtl_tcp,
rtl_power, rtlamr, ffmpeg to the killall endpoint.

The dmrRawOutput div was rendering garbled box-drawing characters from
the dsd-fme ASCII art banner below the signal activity canvas. Remove
the div and filter banner lines (box-drawing chars, version info) in
the parser so they never become events.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The stream thread used a blocking readline() with no timeout, so once
DSD finished outputting its startup banner there were no more events
until actual signal activity. The frontend decayed to zero and appeared
dead. If DSD crashed, the synthesizer state never transitioned to
'stopped' so there was no visual or textual indication of failure.
- Use select() with 1s timeout on DSD stderr to avoid indefinite block
- Send heartbeat events every 3s while decoder is alive but idle
- Detect DSD crashes: capture exit code and remaining stderr, send as
'crashed' status with details and show notification to user
- Frontend properly transitions synthesizer to 'stopped' on process
death (was only happening on user-initiated stop)
- Increase idle breathing amplitude so LISTENING state is clearly
visible (0.12 +/- 0.06 vs old 0.05 +/- 0.035)
- Release device reservation on crash, not just user stop

DMR was missing checkDeviceAvailability/reserveDevice/releaseDevice
calls that other modes (SSTV, listening post) use, so the device
dropdown showed device 0 as available even when another process held
it. Also detect USB claim errors from rtl_fm and surface a clear
message telling the user to pick a different device.

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

The APRS route called app_module.reserve_sdr_device() which does not
exist, causing an AttributeError that Flask returned as an HTML error
page. The frontend then failed to parse it as JSON, showing
"Unexpected token '<'" to the user. Fixed to use claim_sdr_device()
which is the correct function used by all other modes.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
SSTV was not claiming/releasing SDR devices through the centralized
registry, so the device state panel always showed the device as idle
during SSTV use. Added claim_sdr_device/release_sdr_device on the
backend and reserveDevice/releaseDevice on the frontend, matching the
pattern used by all other modes.

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

rtl_fm stderr was sent to DEVNULL, hiding the actual failure reason

Use -o - (stdout) instead of -o /dev/null for audio output, as

dsd-fme uses different protocol flags than classic dsd (e.g. -fs for
DMR instead of -fd, -f1 for P25 instead of -fp). Add -N flag to
