LogTab read the QRZ cookie straight out of SharedPreferences through LocalContext,
inside composition, on every submission - disk access in a composable, around the
repository layer, with the client referenced by fully-qualified name inline. And it
did `if (grid != null)`, so a lookup that failed for any reason left the QSO without
a grid and told the operator nothing.
IQrzGridLookup lives in core:domain, QrzGridLookup in core:data owns the cookie read,
and the view model exposes lookupGrid. The composable now takes a callback and handles
each outcome: a locator is attached, no locator on file passes quietly because nothing
is wrong, an expired cookie says to paste a fresh one, and an unreachable QRZ says so.
That is what the four-outcome QrzGrid type from ce68f487 was for - until now nothing
consumed it and the old nullable client was still the one being called.
Note for anyone extending RadarScreen: the local holding the view model cannot be
referenced as `viewModel` inside a lambda, because that name also resolves to the
composable factory function. Hence the explicitly typed local.
The old QrzGridClient is now unused here but left in place; removing it belongs with
the settings screen, which still calls it to validate a pasted cookie.
`submit()` opened with `if (call.length < 3) return`. During a pass the operator typed
a callsign, pressed done, and nothing happened - no entry, no message, no way to tell
the app had decided against them. None of the logging software surveyed for this work
- N1MM+, DXLog, PoLo, HAMRS - discards a submission silently.
Validation is deliberately loose, because strictness costs more than it saves. Checked
against 28 real callsigns, a typical strict pattern rejects 16 of them: W1AW/4, 2E0ABC,
9A1CCY and SV2ASP/A among others. A pattern permissive enough to accept those also
accepts a Maidenhead locator as a callsign. There is no regex that catches typos without
throwing away legitimate calls, so CallsignEntry rejects only what cannot be a callsign
- empty, one character, illegal characters, all digits, all letters - and reports doubt
as a warning that still logs the contact.
Two warnings exist. A six-character grid-shaped entry says so, because grid and callsign
are exchanged together on FM satellites and the fields sit side by side. A station already
worked this pass says so too, without blocking: the same station on a later pass is a
legitimate new contact, and contest loggers default to working duplicates - DXLog
describes refusing them as an outdated habit.
That warning also replaces the duplicate suppression, which was a 300ms window comparing
the last callsign, admitted in its own comment to be a workaround. It could silently
discard a real second contact, and a set of calls worked this pass is both honest and
more useful. It survives configuration changes via rememberSaveable.
Not addressed here: the QRZ grid backfill still reads the cookie out of SharedPreferences
from inside a composable through LocalContext, and still reports nothing when a lookup
fails. IQrzGridLookup is added for that, but wiring it needs the container, the view model
and the UI to change together.
LoTW refuses a QSO whose SAT_NAME is not spelled as its accepted list has it - its
own help page gives AO7 against AO-7 as a rejection - so the name we upload decides
whether a contact can ever be confirmed. The old code derived it with
substringBefore('('), which returns the descriptive half of a TLE name rather than
the OSCAR designator: measured against live Celestrak amateur data, 0 of 96
satellites resolved to something LoTW accepts. ASRTU-1 went up as ASRTU-1 where
LoTW wants AO-123.
Keying on the name cannot be made to work, because the sources disagree. Of the 49
satellites carried by both Celestrak amateur and AMSAT nasabare, 33 are named
differently - 43017 is RADFXSAT (FOX-1B) in one and AO-91 in the other, 43700 is
ES'HAIL 2 against QO-100 - so which name a QSO got depended on where the operator
fetched their TLE. The catalogue number is identical everywhere, so the table is
keyed on it and OrbitalPass.catNum is now threaded through to the QSO and persisted.
The name path stays as a fallback for contacts logged before the number was
recorded, and got two fixes of its own: it tries either side of the parentheses
rather than assuming the designator is on the left, and tolerates a differing
separator so RADIO ROSTO (RS15) reaches RS-15. Resolution now returns the list's own
spelling, so Arsene is not uploaded as ARSENE and rejected the same way AO7 would be.
Measured on the same data: 3 names resolved before, 20 by name alone now, 30 with
the catalogue number, and no satellite that used to resolve stopped resolving.
The table gained the nine TEVEL-2 satellites after an audit found them missing.
Every source writes those TEVEL2-N while LoTW has TEV2-N, which stripping separators
does not bridge - TEVEL21 is not TEV21 - so they resolved to nothing at all. They
launched in 2025 and are workable now. Their numbering is not sequential: 63217 is
TEVEL2-1 while 63213 is TEVEL2-4.
All 38 entries were cross-checked two independent ways: every catalogue number
appears in the app's own configured sources under a name consistent with the LoTW
spelling, and ARRL's startDate for each name agrees with the launch year in the
TLE international designator - which is what would catch a number pointing at the
wrong object, since a name can match by luck. Nothing here was typed from memory;
an early hand-written draft had AO-123 as 62690 when it is 61781.
Without key(entry.id), Compose reuses component state by position.
When the list reorders mid-countdown (new QSO inserted at index 0,
or QRZ grid backfill triggers refreshTick++), the pending deletion
transfers to a different record and removes the wrong one.
Affected screens: LogTab and WavelogLogScreen.

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).
Previous fix added the content-layer background OUTSIDE the offset
modifier, so the background stayed at the original position and
permanently covered the swipe-reveal area - the yellow trash icon,
75% undo button and 5s countdown were invisible while swiping.
Moved the background INSIDE the offset (background follows the
content): idle = fully covered (no bleed into Sent column), swiping
= yellow trash / undo countdown revealed as before.
Verified: :feature:radar:compileDebugKotlin BUILD SUCCESSFUL.
Not released (batched with pending fixes).
User-test fixes:
1. Log tab frequency now refreshes every second with the transponder
panel (multi-Doppler): selectedRadio derived by uuid from the
per-second transceivers list instead of a remembered stale
reference; display and upload use radio.uplinkLow/downlinkLow
(the same doppler-corrected values the transceiver panel shows).
2. SwipeDeleteRow: content layer now has an opaque background so the
trash icon only appears while swiping (was bleeding through into
the "Sent" column).
3. Settings page order: More-menu items can now move back into the
main menu - button always visible; when the main menu is full (5),
the last non-Settings item is automatically swapped into More.
Verified: check_strings OK (8 files); :app:compileDebugKotlin
BUILD SUCCESSFUL.
User-test fixes (3rd overwrite, version stays 4.5.2/452):
1. Log page was invisible everywhere outside the radar tab:
- allNavItems in MainScreen.kt was missing Screen.WavelogLog ->
not in bottom nav, not in More menu
- SettingsScreen UI-order lists were missing the WavelogLog row ->
not in page order settings either
Now the Log page appears in the More menu (default sub menu tail,
migration appends it) AND in UI settings page-order lists.
2. Frequency display: formatFrequency was MHz.kHz.Hz (145.900.000);
now MHz.kHz (145.900) per request. Applies to transceiver panel
and Log page alike (shared formatter).
3. Log tab frequency: now extracts the exact numbers shown in the
transceiver panel (txBaseFrequencyHz for TX, uplinkLow/uplinkHigh
range for linear) - no re-computation, no extra decimals. Upload
uses the same tuned frequency (Hz precision kept internally).
4. Log page (More menu) table: date+time column (MM-dd HH:mm),
row separators (table lines), uploaded checkmark kept.
Verified: check_strings OK (8 files); :app:compileDebugKotlin
BUILD SUCCESSFUL (includes upstream merge 1a552417).
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);

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

:app:compileDebugKotlin BUILD SUCCESSFUL locally.
Background: the transponder panel CW decoder (added by the upstream
fork author) used a lightweight Kotlin Bayesian engine (core/domain/cw,
kept untouched as a fallback). This change makes the panel use the
Morse Expert engine ported in 4.5.0, so both CW entry points share the
same decoder with a live waterfall.
Changes:
- New mini layout cw_panel_main.xml (waterfall 80dp + decoded text,
status line hidden but ID kept for controller lookup)
- MainActivity.onCreate overload with applyImmersive flag; panel binds
with false so the host window system bars are not touched
- CwDecoderPanel now embeds the mini layout via AndroidView and drives
the MainActivity controller: start/stop/reset map to the engine,
lifecycle follows panel expand (start) / collapse (release mic)
- radar module now depends on feature:cw (+ constraintlayout 2.2.1,
same as cw) for layout + controller reuse
- What's new rewritten in EN/TR/ZH for this release only

Merge upstream commit 2298d8ee 'feat: add mutual radar overlay arrows'. Clean auto-merge: upstream changed RadarView.kt arrow drawing, our sweep optimization stayed intact. No conflicts.
First v4.4.5 was built from c3444aed; this release rebuilds from the merged tree.
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.
- Radar pager now defaults to Transceivers tab (initialPage=0)
- Transceivers don't auto-expand (selectedUuid defaults to null)
- Mutual page default minElev changed from settings value to 0.0
- Display filters out portions below the minElev threshold
- Elevation ring labels were inverted (90/60/30 from outer to inner);
now 30/60/90 correctly from outer ring to center
- Split track paths at the 0/360° azimuth wrap in both MutualRadarView
and main RadarView, so passes crossing due north no longer draw a
line straight across the plot
Track line is no longer time-limited (always shows the whole mutual
arc). The station-B live position is drawn separately on the line
using the same pulsing-dot mode as the local station.
- 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 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
