jopohl/urh ? reverse-engineered prompt

Build me a desktop app for investigating wireless protocols from raw radio signals.

I want to be able to connect common software defined radios, capture signals, visualize them, and easily turn the noisy waveform into bits and messages. The app should help me figure out modulation settings automatically, let me tweak decoding steps, and then organize the recovered protocol into fields and message types. It should also have a way to infer likely packet structure on its own, plus tools for fuzzing simple stateless messages and simulating stateful ones.

Make it feel like a proper cross platform app that runs on Windows, Linux, and macOS, with a clean GUI and support for saving and reopening projects. If you need to check current device support or build details, look up the latest docs online. Please keep the workflow focused on reverse engineering and analysis, not on general radio playback.
