Removes the CW decoder entirely. The feature/cw module was a verbatim
decompilation of Morse Expert 1.15 (VE3NEA, a paid Play Store app),
shipped without licence or attribution, and restricted to the armeabi-v7a
ABI only -- which blocks Google Play distribution (64-bit required since
2019-08).
Deleted:
- feature/cw: 11,519 lines of obfuscated decompiled Java,
libnativedecoderjni.so, layouts and resources
- core/domain/cw: 998 lines of unreachable Kotlin DSP plus its 300-line
test (CwStartListening and friends were never dispatched by any UI)
Cleaned up in feature/radar:
- Removed CwDecoderPanel, CwSubState, CwStatus and 6 CW actions
- Removed the CW branches and decoder plumbing from RadarViewModel
- Dropped now-unused dependencies: :feature:cw, :feature:mutual (was
declared but never imported), androidx.constraintlayout
- Removed radar_cw_* strings from en and zh
Kept deliberately: IAudioCapture, audioCapture and the RECORD_AUDIO
permission -- these are shared with SSTV and must not be removed.
CW decoding is gone until it is rewritten. See branch for the deleted
implementation if you need to reference it.
Replace the radar page calendar action with the map icon and route the action through the Passes map flow so the Passes navigation item remains selected.
When adjusting RX in passband mode (via +/- buttons or slider), the old
code used TransponderMapper.mapDownlinkToUplink (pure passband mapping
without Doppler compensation), producing ~10kHz error at LEO velocities.
Fix: use DopplerFrequencyCalculator.computeUplinkFromDownlinkWithOffset
for the full TX-from-RX round-trip, matching the RX→PASSBAND button
onClick logic. Also fixed frame mismatch: position now uses txLow/txRange
(Doppler-shifted frame) consistently.
Store the offset (kHz) per NORAD catalog id in SharedPreferences so
each satellite's last entered offset is restored when reopening the
frequency calculator.
- isNamedLinearTransponder: match ' Lin' prefix (AO-7 style) and
add fallback branch (hasLinearName && hasLinearMode) for entries
with 'Linear'/'Lin' but no 'transponder' word (AO-7, AO-73)
- add deduplicateTransponders: merge entries sharing the same
uplink/downlink frequency range, preferring non-CW entry
(AO-7 Mode A had separate SSB and CW entries; JO-97 had
separate CW and SSB Transponder entries)
- apply dedup in CalculatorPage filter chain
- 6 new tests, 23 total, all passing
- 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
- 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
