- 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

- 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

Three issues caused POCSAG messages to be incorrectly hidden or
misclassified in the Device Intelligence panel:
1. detectEncryption used a narrow character class ([a-zA-Z0-9\s.,!?-])
to measure "printable ratio". Messages containing common printable
ASCII characters like : = / + @ fell below the 0.8 threshold and
returned null ("Unknown") instead of false ("Plaintext"). Simplified
to check all printable ASCII (\x20-\x7E) which correctly classifies
base64, structured data, and punctuation-heavy content.
2. The default hideToneOnly filter was true, hiding all address-only
(Tone) pager messages. When RF conditions cause multimon-ng to decode
the address but not the message content, the resulting Tone card was
silently filtered. Changed default to false so users see all traffic
and can opt-in to filtering.
3. The multimon-ng output parser only recognized "Alpha" and "Numeric"
content type labels. Added a catch-all pattern to capture any
additional content type labels that future multimon-ng versions or
forks might emit, rather than dropping them to raw output.

Radiosonde route now runs a quick import check before launching the full
subprocess, catching missing Python dependencies immediately with a clear
message instead of a truncated traceback. Error messages are context-aware:
import errors suggest re-running setup.sh rather than checking SDR connections.
Increased stderr truncation limit from 200 to 500 chars and added full stderr
logging via logger.error() across all affected routes (radiosonde, ais, aprs,
acars, vdl2) for easier debugging.
Closes#173

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.

Backend: Add /prefetch-images endpoint that warms the image cache in

Frontend: Trigger prefetch on mode init so images load instantly.
Replace per-request Date.now() cache-bust with a 5-minute rotating
key to allow browser caching aligned with backend max-age.

When navigating from another mode (e.g. pager) to the ADS-B dashboard,
the old process could still hold the USB device. Two fixes:
1. routes/adsb.py: If dump1090 starts but SBS port never comes up,
kill the process and return a DEVICE_BUSY error instead of silently
claiming success with no data.
2. templates/adsb_dashboard.html: Pre-flight conflict check in
toggleTracking() queries /devices/status and auto-stops any
conflicting mode before starting ADS-B, with a 1.5s USB release
delay.

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.

SSTV mode was slow to populate next-pass countdown and ISS location map
due to uncached skyfield computation and sequential JS API calls.
- Cache ISS position (10s TTL) and schedule (15min TTL, keyed by rounded lat/lon)
- Cache skyfield timescale object (expensive to create on every request)
- Reduce external API timeouts from 5s to 3s
- Fire checkStatus, loadImages, loadIssSchedule, updateIssPosition in parallel via Promise.all

The /space-weather/data endpoint made 13 sequential HTTP requests, each

ThreadPoolExecutor to fetch all sources concurrently, reducing worst-case

Reverts the incorrect assumption from f8e5d61 that -c expects a

Passing the directory caused "Config file ... does not exist!" on start.

Running via sudo creates data/radiosonde/ as root. On next run the
config write fails with an unhandled OSError, Flask returns an HTML 500,
and the frontend shows a cryptic JSON parse error.
Three-layer fix:
- start.sh: pre-create known data dirs before chown, add certs/ to the
list, export INTERCEPT_SUDO_UID/GID for runtime use
- generate_station_cfg: catch OSError with actionable message, chown
newly created files to the real user via _fix_data_ownership()
- start_radiosonde: wrap config generation in try/except so it returns
JSON instead of letting Flask emit an HTML error page
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The -c flag expects a directory containing station.cfg, but we were
passing the full file path, so auto_rx could never find its config.

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.

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().
Closes#166

Closes#164. Only pager and sensor routes supported rtl_tcp connections.
Now aprs, morse, and dsc routes follow the same pattern: extract
rtl_tcp_host/port from the request, skip local device claiming for
remote connections, and use SDRFactory.create_network_device(). DSC also
refactored from manual rtl_fm command building to use SDRFactory's
builder abstraction. Frontend wired up for all three modes.

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

The registry used plain int keys (device index), so HackRF at index 0
