While NanoVNA-QT is an excellent tool, it's important to be aware of its current state. The last major official release (20200507) is dated, and the software uses Qt5, with no official update to Qt6 as of late 2025. This has led to it being removed from some Linux distribution repositories. However, the version available on GitHub remains fully functional on Windows and as a self-contained AppImage on Linux.
: While the handheld S-A-A-2 unit may be limited to 201 sweep points, the NanoVNA-QT software allows for up to 1,024 points per sweep, providing much finer resolution for complex filter or antenna tuning.
