Satellite QSOs uploaded with BAND=SAT, which is not a legal ADIF Band
enumeration value (the legal values are concrete bands: 160M/80M/.../
2M/70CM/23CM...). Loggers that fail to parse an unknown band fall back
to a default — observed as QSOs landing in 160m. SAT is only legal as
PROP_MODE (propagation mode), which is already sent for v1.
Changes (WaveLogApi):
- bandFromHz(): map TX frequency to the real ADIF band (2M for VHF,
70CM for UHF, etc.)
- satModeFrom(): derive the ADIF SAT_MODE convention string from TX/RX
bands ("V/U" = VHF up / UHF down, "U/V", "V/S", "U/S"...; empty for
same-band links)
- v2 JSON: band=<real band>, add sat_mode when non-empty
- v1 ADIF: <band:> real band, add <sat_mode:> when non-empty;
PROP_MODE=SAT kept
Verification:
- New tests: SO-50 (145.850 up / 436.795 down) -> band 2M, sat_mode V/U;
AO-73 (435.150 up / 145.950 down) -> band 70CM, sat_mode U/V;
same-band -> empty sat_mode; satellite freqs never map to 160M.
- All wavelog payload tests + full domain suite green.
The fldigi port ran a fixed 600 Hz NCO, so any real signal not inside
600±75 Hz (the 150 Hz filter passband) decoded nothing — the decode rate
was effectively zero unless the tone happened to be on frequency. This
mirrors the behaviour of the removed channelTracker: a sliding spectral
peak detector now steers the NCO to the strongest tone.
Changes:
- Collect raw input, run a 512-pt Hann-windowed FFT every frame, find
the strongest bin in 300..1500 Hz (CW range), smooth-track it.
- First strong peak locks immediately (no RX reset, so the triggering
element survives); later large jumps (>120 Hz) retune and reset the
fldigi state machine; small drifts are eased at 20%.
- Absolute energy floor (peak < 30) so silence/noise never steers.
- estimatedPitch now reflects the tracked tone frequency.
Verification:
- New unit test: 900 Hz "CQ" with decoder initialized at 600 Hz decodes
correctly and pitch moves to ~900 Hz.
- All 9 decoder tests pass; full domain/cw/radar test suites green.
Background:
The CW decoder previously shipped a decompiled copy of the proprietary
Morse Expert 1.15 (com/ve3nea/morse_expert + obfuscated classes,
libnativedecoderjni.so, suncompat black-magic) — a copyright liability.
This removes all of it and reimplements the decoder on the open-source
fldigi (GPL v3) CW engine as a faithful pure-Kotlin port with no JNI.
Changes:
- Delete all Morse Expert reverse-engineered code: MainActivity,
obfuscated packages (B/B0/D/E2/...), suncompat/, pas/nativedecoder,
armeabi-v7a libnativedecoderjni.so, and the original View-based layouts
(activity_main, cw_panel_main, options_menu).
- Add a full fldigi CW pipeline in core/domain/cw:
- CwFldigiDsp: NCO down-conversion, FFT filter, movavg constants
- CwFftFilt: overlap-add FFT band-pass filter (fftfilt port)
- MorseTable + SomTable: full Morse code table + SOM codebook
- CwFldigiDecoder: decode_stream AGC + hysteresis, state machine,
adaptive speed tracking (5-55 WPM), SOM winner/normalize matching
- Rewrite CwDecodeScreen as pure Compose (DeepCW-style waterfall,
live decode line, history, status cards) and CwSettingsDialog
(speed/bandwidth/SOM) with no View interop.
- Replace the Morse Expert panel in TransceiversPage with a Compose
panel driving the same decoder; mic capture at 8000 Hz.
- Drop the forced armeabi-v7a abiFilters now that no native lib exists.
Verification:
- 8 unit tests pass (CQ/HELLO at 18-20 wpm, A-J at 30 wpm with
adaptive tracking, dot/dash/Farnsworth edge cases) — all decode
correctly from synthesized CW.
- :feature:cw and :feature:radar compile; app assembleDebug succeeds.
- APK contains no ve3nea/nativedecoder/morse_expert classes.
WavelogQueue serialized and deserialized every field except
gridsquare: updateGridsquare() wrote it, but save() skipped
put("gridsquare") and all() never read it back, so the QRZ-backfilled
grid was always empty at upload time (GRIDSQUARE never made it into
the ADIF). Add both directions.
WaveLog's parse_frequency() (Logbook_model.php) treats integer input
as Hz but reads string suffixes ("145.852038M" -> 145852038 Hz).
The bare-integer freq/freq_rx values in the v2 JSON envelope could be
misread as MHz by older WaveLog versions, corrupting the band
derivation (145.852 MHz showed up as 160m). ADIF string (v1/v2) was
already correct; now the extra fields match the same semantics.
- Replace HTML parsing with the official AMSAT Satellite Status API v1
(catalog.php + reports.php, JSON): AmSatApiClient (pure JVM, hand
rolled ISO-8601/epoch parsing for minSdk 24) + rewritten
AmSatRepository (satellite list from catalog, reports slotted into
6 days x 12 two-hour slots, status colors per report value)
- Fix edge-to-edge: status bar / navigation bar insets on the status
page (refresh button and update time were unreachable)
- Version 4.5.5 (455), What's new in all 5 locales
All Chinese comments (//, /* */, KDoc) across core/app/feature/build-
logic translated to English (550 lines, 73 files after FT8 rollback).
Code logic untouched - comment text only. Verified: all modules
compileDebugKotlin BUILD SUCCESSFUL.
User-prioritized WaveLog fixes (4.5.5, commit-only per instruction):
- QRZ 对方网格爬虫: QrzGridClient (domain, pure JVM) fetches
https://www.qrz.com/db/{call} with user-supplied cookies (parses
EditThisCookie JSON or raw "k=v; k=v"), extracts Grid Square from
the Detail table. Cookies NEVER built in - entered in settings.
- Settings: WaveLog card top-right gear opens QRZ cookie dialog with
test query button (detects logged-in callsign from cookie, looks up
its grid, shows result or failure in the dialog).
- LogTab: on Enter, async lookup of the other station's grid ->
queue.updateGridsquare -> uploaded with QSO (postQso gridsquare).
- LoTW satellite list: 112 names embedded (lotw.arrl.org config.tq6),
normalizeSatName maps Celestrak TLE names to LoTW names (SAUDISAT-1C
-> SO-50, FUNCUBE-1 -> AO-73, DIWATA-2B -> PO-101, ZARYA/ARISS ->
ARISS); "Update sats" button in WaveLog card downloads the live list
(LotwSatellitesRepo, SharedPreferences persisted, never in build).
- RST: rst_sent/rst_rcvd = 59/59 in both v1 ADIF and v2 JSON.
- Grid mismatch dialog kept (cloud station grid vs station QTH);
QSO gridsquare no longer uses station grid.
- New strings in 5 locales; check_strings 9 files OK.
Verified: core:domain/data + feature:settings/radar + app
compileDebugKotlin BUILD SUCCESSFUL.
New feature/status module: fetches https://amsat.org/status/ and
renders a live status grid in the official site colors:
- Parser (AmSatParser): 47 satellites x 6 days x 12 two-hour slots,
official colors (blue=Active, orange=TLM/Beacon, pink=Not Heard,
deep-orange=Conflicting, gray=none); 598+ report details extracted
from inline JS tooltips (callsign/date/time/grid)
- Three-level viz: color grid -> report count -> tap day cell opens
report list dialog
- Manual refresh with spin animation + last-updated timestamp +
legend row; loading/error states
- New "AMSAT" entry in the More menu (Screen.AmSat), integrated with
page-order / hide-page settings (SettingsScreen screens list,
defaultSubMenuOrder, allNavItems, migration for existing users)
- AmSatRepository via IRemoteSource.getStatusHtml() (UA header);
shared remoteSource promoted to a lazy class property in MainContainer
Radar page Log tab: local entries now grouped by pass session with a
thick divider + satellite label between groups (matches the log page).
What's new updated in EN/ZH/TR/IN/ID. Version bumped to 4.5.3/453.
Not released (user gates all releases).
User request: logs should be separated by satellite/pass. Each pass
session gets an ID = satellite name + AOS timestamp (the second the
elevation hits 0, from OrbitalPass.aosTime), e.g.
"ASRTU-1-20260804-2014". Log page groups entries by session:
group title (satellite - local time) + thick divider line between
groups (md --- style); legacy entries without sessionId fall into
"Ungrouped" at the end.
- WavelogQso: +sessionId (persisted in queue JSON)
- LogTab: sessionId built from satelliteName + aosTimeMs (radar page
passes currentPass.aosTime)
- WavelogLogScreen: grouped rendering + wavelog_ungrouped string (4 locales)
- sessionId UTC yyyyMMdd-HHmm; display converts to local time
Verified: check_strings OK (9 files); :app:compileDebugKotlin
BUILD SUCCESSFUL. Not released (batched).
Official code issues found during review (user-reported):
1. GPS "success" was shown instantly even when no fix was obtained:
- setStationPosition() always returned true (permissions exception
swallowed, async requestLocationUpdates without waiting)
- now: suspend + LocationManagerCompat.getCurrentLocation (GPS
first, network fallback), permission check upfront, 15s timeout,
success only when onLocationChanged fires; SettingsRepo takes
Context for the permission check; ViewModel waits for the real
result and shows "Unable to get location - check permission and
GPS/network signal" on failure (4 locales)
2. Data update faked success on total failure:
- updateFromRemote now counts successful sources; 0 success throws
IOException -> timestamp NOT refreshed, Toast "Update failed -
check your network" (4 locales, new IShowToast resId overload)
- OkHttp timeouts widened: connect 15s / read 20s / write 20s
Verified: check_strings OK; all modules compile.
Release intentionally NOT triggered (user: fix everything first, then
one release).
Background: user's WaveLog server has NO v2 API (all /api/v2/* return
404; /api/qso v1 works - verified with curl). First fix only tried v2
paths, so uploads still failed with 404. Also: Log tab frequencies did
not match the Doppler panel, linear transponders showed a single
frequency instead of the passband range, and errors were toast-only
(no copy).
Changes:
- WaveLogApi: full v1 support with auto fallback
- v2 first (Bearer header + JSON fields), on 404 fall back to v1
(key inside JSON body + ADIF string) - both with and without
index.php prefix
- test connection: v2 GET api/v2/token -> v1 POST
api/get_contacts_adif (validates key + station id)
- station gridsquare is v2-only; on v1 the uploader falls back to
the user's QTH grid (grid check skipped/equal)
- v1 ADIF: call/band=SAT/mode/freq+freq_rx (MHz)/qso_date/time_on
(UTC, compact)/gridsquare(4)/sat_name/prop_mode=SAT, byte-length
field prefixes
- 409 duplicate counts as success in both versions
- Error dialog with copy: test/upload failures now open an AlertDialog
with the full error (incl. actual URL + HTTP code), Copy button
(ClipboardManager) and Cancel; uploader collects the first failure
message
- Log tab frequency sync: LogTab receives txBaseFrequencyHz from the
radar page (the tuned frequency shown in the transceiver panel);
RX is computed through the same Doppler mapping as the Doppler
panel; linear transponders show the full uplink/downlink range
(Doppler-corrected low-high) instead of a single frequency
- Restored uploadWavelogQueue (lost in an earlier patch)
Verified: check_strings.py OK (8 files, 452/4.5.2);
:app:compileDebugKotlin BUILD SUCCESSFUL.
Background: user tested 4.5.2 and reported 4 issues. Same-version
overwrite per user (4.5.2 exists solely for the logbook system).
Fixes:
1. Upload 404 — root cause: user server URL ending in /index.php was
concatenated again (/index.php/index.php/api/v2/...) -> 404. Now:
- normalizeUrl strips trailing /index.php
- every request tries the index.php path first, falls back to the
rewritten path on 404
- 409 conflict (duplicate QSO) counts as success (moves out of queue)
- failure messages include the actual URL + HTTP code for debugging
2. Swipe-to-delete was dead: rowWidth was never measured (0) so the
75% threshold was 0 and the drag was clamped to 0. Now measured via
onSizeChanged + smooth spring/tween snap-back animation.
3. Transponder picker: long card list replaced with an
ExposedDropdownMenuBox dropdown (scrollable menu, pick one).
4. New Log page under the More menu: table view (time / frequency /
satellite / callsign / uploaded checkmark). WavelogQso gains
uploaded flag; uploader marks instead of removing; queue keeps
uploaded entries (500 cap). Old persisted subMenuOrder gets
WavelogLog appended (migration).
Verified: check_strings.py OK (8 files, 452/4.5.2);
:app:compileDebugKotlin BUILD SUCCESSFUL.
Background: satellite operators want to log QSOs during a pass while
watching live frequencies. 4.5.2 adds WaveLog (logbook server) API v2
integration: log from the radar page, upload to a self-hosted WaveLog
instance with grid-mismatch protection.
Changes:
- Radar page: new third tab "Log" between Transceivers and SSTV
- pick a transponder, watch live TX/RX Doppler-corrected frequencies
- enter callsign, Enter stores locally (UTC time + that second's
frequencies sampled together)
- local entry list shows time/frequency/callsign only (no upload
status, per user: proves the entry was saved)
- swipe-to-delete: yellow trash while swiping, turns into Undo at
75%, 5s countdown before auto-delete (custom gesture, no
SwipeToDismissBox)
- Settings: new WaveLog card (server URL / API key / station ID /
auto-upload switch / test connection / upload now buttons) matching
the user's reference screenshot layout
- Upload pipeline: POST /index.php/api/v2/qso with required fields
(station_profile_id, call, band=SAT, mode, qso_date, time_on UTC)
plus freq/freq_rx (Hz), gridsquare (from station profile via
GET /api/v2/station/{id}), sat_name; RST omitted per user
- Grid check: station gridsquare (first 4) vs user QTH (first 4);
mismatch shows a confirm dialog (ignore & upload / cancel)
- Auto upload: 10-minute in-app retry loop (only when switch on);
manual upload button; local queue capped at 500, all entries stored
locally regardless of switch
- Fixed: subMenuOrder was never persisted (4.5.1 regression)
- core/domain: compileOnly org.json (runtime uses Android's)
- Version 4.5.2 (452)
Verified: check_strings.py OK (8 files, 452/4.5.2);
:app:compileDebugKotlin BUILD SUCCESSFUL locally.
Background: 8 bottom-nav items squeeze long English labels on narrow
screens. 4.5.1 introduces the 5+N pattern: 5 main tabs plus a fixed
6th "More" button that pops a second-level menu (spring bounce) with
the remaining pages.
Changes:
- MainScreen: nav split into main (<=5, screenOrder-driven) + more
(subMenuOrder); More button with popup panel + spring animation;
BackHandler closes the menu before navigating back
- MoreMenuPopup: bottom-end card, current page highlighted, scrim
click to dismiss
- UI Settings: page order card now has two zones (main menu, max 5,
Settings locked last with no drag handle / more menu); move buttons
between zones, drag-to-reorder within zones; new subMenuOrder pref
- Defaults: main = Satellites/Passes/Radar/Map/Settings,
more = Mutual/Roaming/CwDecode; old screenOrder migrates by
classifying pages against the default sub menu
- Hard-coded UI strings localized (Tracking/Lat/Lon/Qth/Connect/
Track/Stop/CW permission prompts) into EN/ZH/TR
- NEW Indonesian locale (values-in, 181 strings + cw module strings)
- user rule: every future release must update EN/ZH/TR/IN
- Version 4.5.1 (451)
Verified: check_strings.py OK (8 files, no bare apostrophes);
:app:compileDebugKotlin BUILD SUCCESSFUL locally.
Users can now change the bottom navigation order (previously fixed):
- New "Page order" section under the Settings toggle in the UI
Settings card: vertical list of all 7 pages, each with a drag
handle (new ic_drag drawable, Material drag_indicator glyph) on
the right.
- Drag a handle up/down: the item follows the finger with live
swap + animateItem() placement animation; on release the order is
persisted (OtherSettings.screenOrder, comma-separated in prefs so
order survives; StringSet would not).
- "Reset order" button restores the default order
(Satellites/Passes/Radar/Mutual/Roaming/Map/Settings).
- MainScreen now sorts navItems by screenOrder (empty = default,
stable sort keeps the canonical order); hiddenScreens filtering
unchanged; Settings entry always visible.
- New strings prefs_ui_order_title / prefs_ui_order_reset in
en/zh/tr; What's-new updated in all three locales.
Version stays 4.4.9 (覆盖 per user). Verified: core:data tests
pass, settings + app compile.
Two changes per user request:
1. Data source toggles default OFF with legacy-URL migration
(continuation of the 4.4.8 fix, now also in the dialog): old
example.com placeholder URLs are replaced by the real defaults and
the custom toggles stay off, so the online update never points at a
dead source after upgrading.
2. New "UI Settings" card between Other Settings and Credits:
one switch per bottom-navigation page (卫星/过境/雷达/匹配/漫游/地图/设置
in fixed order). Turning a page off removes it from the nav bar and
the remaining items close up automatically; order is never
rearranged. The Settings entry is always visible (switch disabled)
so the user can never lose access to settings. Persisted via
OtherSettings.hiddenScreens (StringSet of Screen.screenId; screenId
added to the Screen sealed class - simpleName is unsafe under R8).
Version bump per fork convention: 4.4.8 -> 4.4.9, versionCode 449.
What's-new updated in en/zh/tr.
Verified: core:data + core:domain tests pass, all modules compile.
The "Custom URL" dialog's two URL fields now control the default
source used by the online update, per the user's intent (one-time
setup, no extra steps per update):
- Defaults are real URLs now: TLE = Celestrak "All" (active group
CSV), transceivers = SatNOGS API. The example.com placeholders are
gone.
- updateFromRemote(): the "All" TLE entry and the "SatNOGS" entry are
replaced by the user's URLs when the corresponding custom toggle is
ON and the URL is non-blank; otherwise the real defaults are used.
The old "Other" appended-source logic is removed - the toggle now
means "use my URL for this source" instead of "download an extra
source". Each source (TLE / transceivers) is independent.
- Each URL field gained a reset (loop) icon button on the right that
restores the default URL text (new ic_reset drawable, Autorenew
vector). Strings added in en/zh/tr.
Test updated: custom TLE URL data now lands under the "All" type
instead of "Other". Verified: core:data tests pass, settings + app
compile. Version stays 4.4.8 (覆盖 per user).
Reverts the auto-update machinery after review — the page now simply mirrors the station position (站位) from the shared settingsRepo.stationPosition StateFlow, exactly what the Settings page shows:
- RoamingScreen: removed the LocationManager listeners, the 30s re-request loop, the provider filter and the location-disabled hint. No polling, no auto-updates; coordinates are whatever the station GPS says.
- Settings: removed the '漫游位置实时更新' toggle (stateOfRoamingLive, key, action, strings en/zh/tr) that caused the 'Other' card to overflow — the sixth unlabeled switch clipped past the card's rounded bottom edge was that row overflowing a fixed-height card. Card height back to 268.dp, five rows fit again.
Verified: core:domain tests, roaming/settings/app compile clean; zero references to RoamingLive remain.
Rework the Roaming page after user review. It is now a faithful port of the QTH定位器 location panel, not a loose re-skin:
UI (matching the reference layout):
- GPS status dot (real: green when a fresh fix exists, outline when stale/missing) + date + time header
- Lat/Lon rows with DMS and 5-decimal display, big 8-char locator centered below
- 3x3 grid of neighboring 4-char squares with the reference proportions: center column ~2.6x wider (21.4% : 56.2% : 21.4%) and center row the tallest (31.5% : 35.9% : 31.7%); red position marker now placed at the fractional position of the fix inside the center cell (was fixed center)
- No oversized GPS button: live updating is now a Settings toggle '漫游位置实时更新' (stateOfRoamingLive, default on) that drives periodic location refresh
Style & night-mode safety:
- All colors come from MaterialTheme.colorScheme (surfaceVariant/secondaryContainer/error) — no hardcoded cyan/blue from the original app. The red night filter (ColorMatrix keeping only the R channel) blanked the old hardcoded palette; theme colors survive it.
- Chinese nav label '漫游' added to values-zh (was missing, showing English 'Roaming')
Settings:
- OtherSettings.stateOfRoamingLive persisted (default true), toggle row in Other card, height adjusted
Verified: feature:roaming, feature:settings, app compile clean.
Ports the QTH定位器 (com.us1pm.gridsquarelocator) location panel into Look4Sat as a new 'Roaming' page, restyled with the app's own look.
UI (top to bottom):
- Info header: GPS status dot, big 8-char locator, Lat/Lon rows with DMS + 5-decimal display, and a GPS 定位 button
- 3x3 grid panel: the current 4-char Maidenhead square (e.g. OL42) centered, surrounded by its 8 neighbors (OL33..OL51), with a red position marker in the center cell
Logic:
- QthConverter gains qthNeighbors(square) building the 3x3 grid with field/square carry at boundaries (AA00 wraps to RR99, IO91 crosses into J field), and qthToSquare(locator) extracting the 4-char square
- Verified against the decompiled app algorithm and the reference screenshot (OL42 grid matches exactly); 9 unit tests cover normal, boundary and field-wrap cases
Navigation:
- New bottom-nav item 'Roaming' between Match and Settings, with a crosshair icon
- New feature:roaming module (ViewModel + Compose screen) registered in the app
Build config:
- Lowered Gradle JVM heap from -Xmx6g to 768m: the 2GB build server froze on the old value; heavy release builds stay on GitHub Actions
Station lat/lon was stored rounded to 4 decimals (~11 m). Bump to 5 decimals (~1.1 m), slightly better than GPS hardware accuracy without showing noise.
- SettingsRepo.setStationPosition: round(4) -> round(5)
- QthConverter.qthToPosition: round(4) -> round(6) so 10-char locators fully roundtrip
- Update QthConverterTest expected values to 6-decimal precision
Port the 8-char (4-pair) Maidenhead grid algorithm from the
"QTH定位器 2.0" app (com.us1pm.gridsquarelocator) into QthConverter
so locator precision matches common grid tools instead of being
truncated to 6 chars.
Previously positionToQth() emitted only 6-char locators and
qthToPosition() discarded everything past the 6th character via
take(6), losing the finer 30" x 15" resolution carried by 8-char
grid squares.
What changed:
- positionToQth(lat, lon, precision = 8) now emits 8-char locators
by default; precision = 6 / 10 available for backwards
compatibility and maximum resolution (1.25" x 0.625").
- qthToPosition() parses 6/8/10-char locators and returns the center
of the finest encoded cell (30" x 15" for 8-char, 1.25" x 0.625"
for 10-char) instead of the 6-char cell center.
- Locator validation regex tightened: 6/8/10 chars accepted,
4-char strings like "JN58" are now rejected as invalid.
- Boundary clamping added so lat = 90 / lon = 180 no longer overflow
the A-R / 0-9 / a-x alphabet (previously produced invalid chars).
Also fixed a pre-existing compile error in RadarView.kt: a delegated
property was assigned after declaration ("by" on an already declared
val). Converted the sweep angle to an if/else expression.
Verification:
- QthConverterTest extended to 5 test cases covering 6/8/10-char
roundtrips, invalid input, boundary coordinates and roundtrip
stability.
- Cross-checked against a Python reference model of the decompiled
APK algorithm: 20k random roundtrips at 8 and 10 chars, 0 failures.
- :core:domain:test green; :app:compileDebugKotlin passes.
- MutualViewModel is Activity-scoped, so returning from Radar keeps query results
- TrackSampleData gains time field for live cut-off
- Removed standalone mutual card from radar page
- RadarViewCompose draws optional dashed station-B track + current dot
- RadarScreen builds trackB from mutual data up to current time
- MutualPass now carries TrackSample (azimuth/elevation for both stations)
- New MutualRadarView: polar plot with elevation rings (30/60/90),
cardinal spokes, solid A-track vs dashed B-track, AOS/LOS markers
- Shown in expanded mutual pass card and radar page mutual card
- Fix cubic Bezier control points (proper Catmull-Rom to Bezier conversion)
- Refine AOS/LOS more robustly by walking from edge into the pass window
- Still 5s sampling for smooth curves
- Add newColumnCount tracking to CwSpectrogram
- CwDecoder now processes each new column individually for timing
- Each column = 8ms at 8000 Hz sample rate
- Proper per-column iteration through spectrogram history
Complete rewrite inspired by Morse Expert / CW Skimmer (VE3NEA):
- CwFFT: radix-2 FFT (256-point) for time-frequency analysis
- CwSpectrogram: sliding-window waterfall (40 cols x 33 bins, 8ms resolution)
- CwBayesianDecoder: Gaussian probability replaces hard dit/dash thresholds
- CwChannelTracker: multi-channel peak detection (up to 3 signals)
- CwDecoder: integrates all components, monitors 200-1200 Hz simultaneously
Key advantages over v2 (ggmorse):
- Frequency-agnostic: full spectrum monitored, not locked to one tone
- Multi-channel: tracks multiple signals in parallel
- Bayesian: probability-based decisions, not hard ratios
- Doppler tolerant: frequency drift just moves energy between bins
- After initial pitch lock, re-scan every ~8 seconds in a narrow
±100 Hz window around the current pitch estimate
- Only re-lock if pitch change > 20 Hz (avoids jitter)
- Helps maintain lock when Doppler tracking has residual error
- Add CwDsp with FIR bandpass filter, envelope detection, Goertzel tone detector
- Add CwDecoder with real-time Morse timing analysis and character lookup
- Add CW state/actions to RadarState, wire into RadarViewModel
- Add collapsible CW decoder panel to transceivers page
- 19 unit tests covering DSP, Morse table, and decoder state
- Shares IAudioCapture with SSTV, auto-stops SSTV when CW starts
- Add DopplerFrequencyCalculator utility with passband mapping + Doppler correction
- Add MHz input UI with real-time 1Hz refresh during pass
- Add kHz offset for downlink frequency correction
- TX/RX fields on same row for compact layout
- 40 unit tests covering linear/FM/inverted transponders
