3 years ago Looks like an issue with audio on Windows. I never used GNU Radio on Windows so I cannot help here. If you are mainly interested in RDS (and not in audio), just replace the audio source with a null source or similar.
Hello, I tried the rds tx example with GNU 3.7, Windows 10 and a HackRF but it is not working. Do I have to configure something special? This is my console output:
