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

Version 0.7 of Open Tuner, released on April 27, 2023, marked a significant milestone by introducing proof-of-concept dual tuner functionality for the BATC Minitiouner. This C# client, inspired by Heather Lomond's Longmynd project, aims to leverage both tuners and demodulators within the NIM module, a capability crucial for advanced Digital Amateur Television (DATV) operations on QO-100 and terrestrial links. My own experience with DATV often involves juggling multiple receive paths, so a unified client like this simplifies the workflow considerably.

Further enhancing its utility, version 0.9 (February 11, 2024) integrated support for the Raspberry Pico, utilizing Colin (G4EML)'s PicoTuner firmware. This offers a more accessible and cost-effective alternative to the traditional FTDI module, streamlining dual tuner setups with a single USB cable. The project's evolution reflects a practical approach to overcoming hardware availability challenges.

The software is developed using Visual Studio 2019/2022 and .NET Framework 4.7.2, requiring specific Nuget packages like VLC/Websocket and an ffmpeg folder for full operation. It's an active, community-driven effort, with the source code openly available on GitHub for contributions and bug reporting, embodying the collaborative spirit of amateur radio development.
