Meteor: onopen callback used closure variable _ws instead of `this`,
so a double-click during CONNECTING state sent on the wrong socket.
Also clean up any in-progress connection on re-start, not just running ones.
Setup: make apt-get update non-fatal so third-party repo errors
(e.g. stale PPAs on Debian) don't abort the entire install.

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

Reusable SVG bar waveform (SignalWaveform.Live) that animates in response
to incoming SSE data — idle breathing when stopped, active oscillation
proportional to telemetry update frequency, smooth decay on signal loss.
Integrated into radiosonde Status section with ping() on each balloon
message and stop() on tracking stop. Also hardens the fetch error path
to show a readable message instead of a JSON parse error when the server
returns HTML.

Extends the rtl_tcp support (added in 13be720 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.

- Change 'already_running' to 'already_scanning' status in bluetooth_v2
so frontend recognizes the response and connects the SSE stream
- Hide pagerScopePanel and sensorScopePanel in switchMode() to prevent
audio waveform bars leaking into other modes
- Clear devices Map, pendingDeviceIds Set, and UI in BluetoothMode.destroy()
to prevent memory accumulation on repeated mode switches

Mode modules were leaking EventSource connections, setInterval timers,
and setTimeout timers on every mode switch, causing progressive browser
sluggishness. Added destroy() to 8 modules missing it (meshtastic,
bluetooth, wifi, bt_locate, sstv, sstv-general, websdr, spy-stations)
and centralized all destroy calls in switchMode() via a moduleDestroyMap
that cleanly tears down only the previous mode.

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 globe wasn't rendering because initGlobe() used setTimeout(100)
which can race with the display:none removal by switchMode(). Both
GPS and WebSDR modes use requestAnimationFrame to wait for the browser
to compute layout before initializing Globe.gl.
- Replace setTimeout with RAF-based retry loop (up to 8 frames)
- Add try-catch around Globe() init with fallback message
- Match the proven pattern from GPS and WebSDR modes
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Fix globe destroyed on re-render by preserving canvas DOM node across
renderLocationCard() calls instead of recreating from scratch
- Reduce globe.gl camera minDistance (180->120) so globe is visible in
200px container
- Clear stale globeInstance ref when canvas is gone
- Enlarge CPU gauge (90->110px), percentage label (18->22px), core bars
(24->48px height), and detail text (11->12px)
- JS fetchLocation() now supplements server response with client-side
ObserverLocation.getShared() from localStorage when server returns
'default' or 'none', picking up manual coordinates from settings modal
- Location priority: GPS > config env vars > manual (localStorage) > default

- Add third location fallback to utils/constants (London 51.5074/-0.1278)
so location always resolves even without GPS or env vars configured
- Remove min-height from sys-card to eliminate wasted space
- Switch System Info to vertical key-value layout filling the card
- Clean up OS string (strip glibc suffix), use locale date for boot time
- Bump info grid font size from 11px to 12px for readability

Replace broken app.gps_state lookup with utils.gps.get_current_position()

The satellite dropdown had no change listener, so selecting a different

When the stop POST timed out (5s), lifecycle was set to 'idle' on error,
allowing checkStatus to see running=true and reconnect SSE. Now:
- stop .then() stays in 'stopping' on timeout/error instead of going idle
- checkStatus skips reconnect when lifecycle is 'stopping' post-timeout
but still transitions to idle when server confirms running=false
- LOCAL_STOP_TIMEOUT_MS raised from 5s to 12s to match server cleanup time
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The previous stopPromise guard only prevented new polls from being
dispatched. Polls already in-flight before stop was clicked could still
return with running=true and override the stopping lifecycle, causing
SSE reconnection and an apparent restart loop. Add a second guard in
the .then() handler to check stopPromise/lifecycle before acting.

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.

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.

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.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Enable direct sampling (-D 2) for RTL-SDR at HF frequencies below 24 MHz
so rtl_fm can actually receive CW signals. Add startup health check to
detect immediate rtl_fm failures. Push stopped status event from decoder
thread on EOF so the frontend auto-resets. Add frequency placeholder and
help text. Fix stop button silently swallowing errors.

Resolved conflict in static/js/modes/weather-satellite.js:
- Kept allPasses state variable and applyPassFilter() for satellite pass filtering

Fix "What's New" section shifting up/down on smaller screens (#157) by
isolating the logo pulse animation to its own compositing layer, stabilizing

Morse mode improvements: relocate scope and decoded output panels to the

When an error occurred with an out-of-range span (e.g. 30 MHz on

command builders to support custom install locations
