- Fix XSS: escape ASCII output in innerHTML via escapeHtml()
- Fix deadlock: use put_nowait() for queue ops under ook_lock
- Fix SSE leak: add ook to moduleDestroyMap so switching modes
closes the EventSource
- Fix RSSI: explicit null check preserves valid zero values in
JSON export

memory growth on busy bands
- Validate timing params: wrap int() casts in try/except, return
400 instead of 500 on invalid input
- Fix PWM hint: correct to short=0/long=1 matching rtl_433
OOK_PWM convention (UI, JS hints, and cheat sheet)

- Timing presets: five quick-fill buttons (300/600, 300/900, 400/800, 500/1500, 500 MC)
that populate all six pulse-timing fields at once — maps to CTF flag timing profiles
- RSSI per frame: add -M level to rtl_433 command; parse snr/rssi/level from JSON;
display dB SNR inline with each frame; include rssi_db column in CSV export
- Auto bit-order suggest: "Suggest" button counts printable chars across all stored
frames for MSB vs LSB, selects the winner, shows count — no decoder restart needed
- Pattern filter: live hex/ASCII filter input above the frame log; hides non-matching
frames and highlights matches in green; respects current bit order
- TSCM integration: "Decode (OOK)" button in RF signal device details panel switches
to OOK mode and pre-fills frequency — frontend-only, no backend changes needed

Several modes didn't pass sdr_type to claim_sdr_device(), defaulting to
'rtlsdr' and triggering an rtl_test USB probe that fails for HackRF with
a confusing "check that the RTL-SDR is connected" message.
- Add sdr_type to frontend start requests for rtlamr, weather-sat, sstv-general
- Read sdr_type in backend routes and pass to claim/release_sdr_device()
- Add early guard returning clear "not yet supported" error for non-RTL-SDR
hardware in modes that are hardcoded to RTL-SDR tools
- Make probe_rtlsdr_device error message device-type-agnostic

When the /devices fetch hasn't completed or fails, parseInt on an empty
select returns NaN which JSON-serializes to null. The backend then calls
int(None) and raises TypeError. Fix both layers: frontend falls back to
0 on NaN, backend uses `or` defaults so null values don't bypass the
fallback.
Also adds a short TTL cache to detect_all_devices() so multiple
concurrent callers on the same page load don't each spawn blocking
subprocess probes.

Add dropout tolerance (2 blocks ~40ms) to bridge brief signal gaps that

Stock rtl-sdr packages don't support the -T bias-tee flag (only
RTL-SDR Blog builds do). Passing -T to stock rtl_sdr causes an
immediate exit, breaking meteor scatter and waterfall modes.
Now probes the tool's --help output before adding -T, with a regex
that avoids false-matching "DVB-T" in the description text.

Full-stack meteor scatter monitoring mode that captures IQ data from
an RTL-SDR, computes FFT waterfall frames via WebSocket, and runs a
real-time detection engine to identify transient VHF reflections from
meteor ionization trails (e.g. GRAVES radar at 143.050 MHz).
Backend: MeteorDetector with EMA noise floor, SNR threshold state
machine (IDLE/DETECTING/ACTIVE/COOLDOWN), hysteresis, and CSV/JSON
export. WebSocket at /ws/meteor for binary waterfall frames, SSE at
/meteor/stream for detection events and stats.
Frontend: spectrum + waterfall + timeline canvases, event table with
SNR/duration/confidence, stats strip, turbo colour LUT. Uses shared
SDR device selection panel with conflict tracking.

SSE EventSource connections for AIS, ACARS, VDL2, and radiosonde were
not closed when switching modes, causing fd exhaustion after repeated
switches. Also fixes socket leaks on exception paths in AIS/ADS-B
stream parsers, closes subprocess pipes in safe_terminate/cleanup, and
caches skyfield timescale at module level to avoid per-request fd churn.

sqlite3.connect() opens read-only files without error — the failure
only surfaces on the first write (INSERT). Add an upfront os.access()
check on both the directory and file, with a clear error showing the
owner and the exact chown command to fix it.

When start.sh runs via sudo, chown instance/ and data/ back to the
invoking user so the SQLite DB stays accessible without sudo. Also
adds a clear error message in get_connection() when the DB can't be
opened due to permissions.

Extends the rtl_tcp support (added in c1339b6 for APRS, Morse, DSC) to
the weather satellite mode. When a remote SDR host is provided, SatDump
uses --source rtltcp instead of --source rtlsdr, local device claiming
is skipped, and the frontend sends rtl_tcp params via getRemoteSDRConfig().

The custom SIGINT/SIGTERM handler in utils/process.py overrode
gunicorn's own signal management, causing KeyboardInterrupt to fire
inside the gevent worker on Ctrl+C instead of allowing gunicorn's
graceful shutdown. Now detects if another signal manager (gunicorn)
has already installed handlers and defers to it.

Re-implements envelope detection on top of the rewritten Morse decoder.
Addresses PR #160 review feedback:
- Rebase: rebuilt on current upstream/main (lifecycle state machine)
- Gap thresholds: 2.0/5.0 for envelope only; goertzel keeps 2.6/6.0
- Frequency validation: max_mhz=1766 for envelope, 30 for goertzel
- Tests: EnvelopeDetector unit tests + envelope-mode decoder test
- Envelope uses direct magnitude threshold (no SNR/noise ref)
- Goertzel path completely unchanged

rtl_test opens the USB device during probing. After killing the
process, the kernel may not release the USB interface immediately.
dump1090 then fails with usb_claim_interface error -6. Add a 0.5s
delay after probe cleanup to allow the kernel to fully release the
device before the actual decoder opens it.

rtl_test -t often exits non-zero after finding a device (e.g.
"No E4000 tuner found, aborting" with R820T tuners). The return
code fallback was firing even when the "Found N device(s)" success
message had already been matched. Track device_found separately
and only use return code as fallback when no success was seen.

The success check ('Found' in line and 'device' in line) matched
"No supported devices found" since both keywords appear. Add a
pre-check for negative device messages, a return code fallback,
and a clearer error message.

- Pass config file path (not directory) to auto_rx -c flag
- Use absolute paths in generated station.cfg since auto_rx runs
with cwd set to its install directory
- Teach dependency checker about auto_rx.py at /opt install path

Move adsb_active_device/sdr_type assignment to immediately after
claim_sdr_device so stop_adsb() can always release the device, even
during startup. Sync sdr_type_str after SDRType fallback to prevent
claim/release key mismatch. Clear active device on all error paths.
Replace blind 3s sleep for dump1090 readiness with port-polling loop
(100ms intervals, 3s max). Replace subprocess.run() in rtl_test probe
with Popen + select-based early termination on success/error detection.

Guard checkStatus() against in-flight stop to prevent status poller
from overriding stopping state and reconnecting SSE. Lower SNR floor
from 1.3 to 1.15 to accommodate weaker CW signals. Add SNR/noise_ref
to scope events and metrics for real-time threshold debugging.

Widen noise detector offset from ±100Hz to ±200Hz to reduce spectral
leakage into the noise reference, and scale threshold_multiplier for
SNR space (2.8 → 1.54) so real CW signals reliably trigger tone
detection instead of producing all-E's at 60 WPM.
Fix misleading "decoder startup" timeout message on stop requests and
increase stop timeout from 2.2s to 5s.

The previous magnitude-based threshold couldn't distinguish CW tone from
AGC-amplified inter-element silence — the Goertzel level stayed above
threshold permanently, preventing any tone OFF transitions and thus zero
character decodes.
Switch tone detection to use SNR (tone_mag / adjacent_band_noise_ref).
Both bands are equally amplified by AGC, so the ratio is gain-invariant.
Also replace the conditional noise_ref guard with unconditional blending
so the noise floor tracks actual ambient levels continuously.

Filter decoder-thread 'stopped' status events that race with the route
lifecycle, causing the frontend to drop back to idle on first start.
Pull noise floor upward using adjacent-frequency Goertzel reference when
warmup calibration runs before AGC converges, preventing permanent
tone-on with zero character decodes.

BufferedReader.read(n) on non-interactive streams (Python 3.14) blocks
until the full n bytes accumulate, starving the decoder of real-time
PCM data. Use os.read() on the raw file descriptor instead, which
returns as soon as any data is available. Falls back to .read() for
file-like objects without fileno() (e.g. BytesIO in tests).

Replace select.select()+os.read() with a blocking reader thread feeding

rtl_fm prints device info, tuning, and errors to stderr but the morse
route only logged these server-side. Now stderr lines are forwarded to
the morse queue as info events, displayed in a compact diagnostic log
below the scope canvas. After 10s with no audio data, the scope text
escalates to prompt the user to check the SDR log.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Replace blocking rtl_stdout.read() with select()+os.read() so the
decoder thread emits diagnostic heartbeat scope events when rtl_fm
produces no PCM data (common in direct sampling mode). Add waiting-state
rendering in the scope canvas and hide the generic placeholder/status
bar for morse mode.

Add automatic gain control (AGC) before Goertzel processing to normalize
quiet audio from direct sampling mode where the -g gain flag has no effect.
