mckero 9b0d543f12 refactor(cw)!: replace legacy CW engine with DeepCW in both entry points
DeepCW 成为唯一 CW 解码内核, 不保留旧引擎作兜底 (用户决定: 完全移植)。

删除旧内核 (1298 行):
- CwDecoder.kt / CwBayesianDecoder.kt / CwChannelTracker.kt / CwSpectrogram.kt
- CwDsp / CwFFT / CwSTFFT / CwGoertzel / CwFilter / CwResampler.kt
- CwDecoderTest.kt
旧内核的自动定频与 squelch 门控由 DeepCW 的 400-1200Hz 固定频窗替代 ——
模型自带定频, 不再需要频谱峰值跟踪和噪声门。

两个 CW 入口都改接 DeepCW:
1. feature:cw 独立整页 CwDecodeScreen.kt 重写为纯 Compose (瀑布图 -> 实时行
   -> 历史区), 移除 AndroidView/LayoutInflater 和被删的 activity_main 布局;
   删除 CwSettingsDialog.kt (旧引擎的手动音调/带宽面板, DeepCW 全自动无需)
2. feature:radar 内嵌可折叠面板改走 ViewModel 的 CW state/action, 移除
   Morse Expert 控制器与 cw_panel_main 布局
   (该面板此前注释写明 "no longer feeds it", ViewModel 里的 CW 通路是死代码)

新增 CwWaterfall.kt: 复用 CwDeepSpectrogram 绘制瀑布图, 显示的正是模型
分析的 400-1200Hz 频段与同一批幅值。

接口接线:
- IMainContainer.provideCwDecoder() 提供 ICwDecoder (实现需 Context 读 assets)
- RadarViewModel 构造新增 cwDecoderFactory, onCleared() 中 close() 释放
  OrtSession 避免原生内存泄漏
- 删除已无调用方的 RadarAction.CwSetToneFreq (DeepCW 定频固定, 无参数可调);
  CwSubState.cwToneFreq 语义改为只读显示检测到的音调

依赖清理:
- feature:radar 不再依赖 feature:cw 与 constraintlayout
- feature:cw 不再依赖 constraintlayout

字符串: feature:cw 清理 Morse Expert 遗留串 (premium/rate/help/
tap_back_again_to_close/purple_500), 按 en/zh/tr/in/id 五语补全新串;
core:presentation 补 radar_cw_tone / radar_cw_waiting 五语。

验证:
./gradlew :core:domain:test => 4 个测试类全绿
./gradlew :feature:cw:compileDebugKotlin => BUILD SUCCESSFUL
./gradlew :feature:radar:compileDebugKotlin => BUILD SUCCESSFUL
./gradlew :core:data:compileDebugKotlin => BUILD SUCCESSFUL

Look4Sat: Satellite tracker

Look4Sat CI

Get it on Google Play Get it on F-Droid

Radio satellite tracker and pass predictor for Android, inspired by Gpredict

Track satellite passes with ease!

Thanks to Celestrak and SatNOGS you have access to over 9000 active satellites.
You can search the entire database by NORAD Catalog Number or the satellite's name.

Orbital positions and passes are calculated relative to your location.
To get reliable data make sure to set the station position via the app Settings.

The application is built using Kotlin, Coroutines, Jetpack Compose and Navigation.
It is now and always will be completely ad-free and open-source.

Main features:

  • Predicting satellite positions and passes for up to 10 days
  • Showing the list of currently active and upcoming satellite passes
  • Showing the active pass progress, polar trajectory and transceivers info
  • Showing the satellite positional data, footprint and ground track on the map
  • Custom TLE satellite data import is available via Three Line Element .txt files
  • Offline first: calculations are made offline. Weekly TLE data update is recommended.
