Description

Can someone please confirm whether Windows version has PSK working as it should for interpretation window?

Expected Behavior

interpretation window to show values underneath as phase changes

Actual Behavior

showing as either all zeroes or all ones

Steps To Reproduce

Took capture from a PSK device directly in to URH from the capture window. saved signal and went to interpretation window set parameters as required tried with both autodetect and manually setting with the same end result

Research direction
The issue reports that PSK interpretation shows all zeros or ones on Windows. Start by examining the PSK demodulation logic in the URH codebase, likely in the signal processing or interpretation modules. Check if there are any Windows specific file path or encoding issues that affect reading captured signals. Also review comments in the issue for any additional user provided information or attempted workarounds.
