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
I was setting the Tx frequency only when we were
in Tx mode, but the Icom 705 will accept the
command to set the Tx frequency even when in Rx mode, so
there is no need to check the PTT state before sending the command.
- Added support for Icom IC-705 radio model with split mode functionality.
- Updated RadioTrackingService to handle single-radio split mode and dual-radio configurations.
- Modified MainContainer to provide appropriate radio controllers based on selected model.
- Enhanced SettingsRepo to include split mode preference in radio control settings.
- Updated UI in SettingsDialog to allow toggling of split mode for IC-705 and adjust device selection accordingly.
- Improved handling of baud rates based on selected radio model.
- Added extended operations in IRadioController for IC-705 specific commands.
