  "description_en": "Qt graphical digital signal analyzer by Gonzalo José Carracedo Carballal, built on his Suscan and Sigutils libraries; its user manual names reverse engineering of radio signals with unknown parameters as the main use. It receives from SoapySDR-supported SDRs or plays back recorded I/Q and WAV files, shows spectrum and waterfall views, and lets analysts measure captured stretches in a time window with carrier recovery, transforms and symbol sampling. Inspector tabs run user-tunable PSK, FSK and ASK demodulators with parameter estimation and can forward demodulated samples; it also decodes analog video and previews AM, FM and SSB audio.",

    "Reviewed at master commit 70f688b (2026-02-11); the README says SigDigger, SuWidgets, Suscan and Sigutils all keep their latest working changes on master. The last stable release is v0.3.0 (2022-07-05, with an x86-64 Linux AppImage and a macOS DMG); a rolling pre-release tagged latest, rebuilt on 2025-04-08, provides a 0.3.0 Linux AppImage and a Windows zip. The bundled user manual is version 0.3.0, dated 2022-06-27, and calls itself a draft.",
    "The README targets GNU/Linux and macOS: Linux users can run the AppImage (the manual asks for glibc 2.27 or newer), macOS DMGs are made on request, and the README says reproducible Windows builds with all DLL dependencies are not currently possible, leaving Windows users to build from source. Source builds install Sigutils and Suscan (CMake), then SuWidgets and SigDigger (qmake with Qt 5.9+ or Qt 6), in that order; SigDigger.pro also links FFTW through pkg-config. The README also offers the author's blsd script, which builds everything in a local directory.",
    "Live analysis needs an SDR receiver supported by SoapySDR; without one, recorded RF/IF data can be loaded from WAV or raw complex-float I/Q files. The repository commits no signal recordings. Plugins such as AmateurDSN, APTPlugin, AntSDRPlugin and ZeroMQPlugin live in separate repositories.",
    "LGPL-3.0 (LICENSE); the README says the spectrum widget is Gqrx's plotter with modifications. The manual describes symbol decision as human-guided, so recovered symbols and any protocol interpretation remain the analyst's work."

    "审阅对象为 master 分支提交 70f688b（2026-02-11）；README 说明 SigDigger、SuWidgets、Suscan 和 Sigutils 都把最新可用的改动保存在 master 分支。最近的稳定版为 v0.3.0（2022-07-05，提供 x86-64 Linux AppImage 和 macOS DMG）；标签为 latest 的滚动预发布版于 2025-04-08 重新构建，提供 0.3.0 版 Linux AppImage 和 Windows 压缩包。仓库附带的用户手册为 0.3.0 版，日期为 2022-06-27，并自称仍是草稿。",
    "README 面向 GNU/Linux 和 macOS：Linux 用户可直接运行 AppImage（手册要求 glibc 2.27 或更新版本），macOS DMG 按需制作；README 称目前无法以可复现的方式制作包含全部 DLL 依赖的 Windows 构建，Windows 用户需自行从源码构建。从源码构建须依次安装 Sigutils 和 Suscan（CMake），再构建 SuWidgets 和 SigDigger（qmake，需 Qt 5.9+ 或 Qt 6）；SigDigger.pro 还通过 pkg-config 链接 FFTW。README 另外提供作者的 blsd 脚本，可在本地目录中完成全部构建。",
    "实时分析需要 SoapySDR 支持的 SDR 接收设备；没有设备时，可从 WAV 或原始复数浮点 I/Q 文件载入录制的射频/中频数据。仓库没有提交任何信号录制文件。AmateurDSN、APTPlugin、AntSDRPlugin 和 ZeroMQPlugin 等插件位于单独的仓库。",
    "采用 LGPL-3.0（LICENSE）；README 说明其频谱控件是经过修改的 Gqrx 绘图控件。手册指出符号判决需由人工引导，因此恢复出的符号及其协议含义仍需分析人员自行判断。"
