Open Tuner: Open-source Windows Client for BATC Minitiouner DATV

Open Tuner is an open-source Windows client developed in C# for communicating directly with the BATC Minitiouner over USB. It is designed for DATV experiments, including QO-100 and terrestrial applications. The project ports significant code from Heather Lomond's Longmynd project and aims to utilize both tuners and demodulators within the NIM module. Version 0.7 (2023/04/27) introduced proof-of-concept dual tuner functionality. For BATC V2 Minitiouners, simple modifications enable dual output, while Minitiouner Pro variants with two USB ports are ready for dual tuner use. Version 0.9 (2024/02/11) introduced support for the Raspberry Pico as an alternative to the FTDI module, using Colin (G4EML)'s PicoTuner firmware, offering cost and availability advantages, and enabling dual tuner functionality with a single USB cable. The code is open-sourced on GitHub, developed with Visual Studio 2019/2022 and .NET Framework 4.7.2, requiring Nuget packages (VLC/Websocket) and an ffmpeg folder.
