Hi everyone, first off: Awesome project! I really appreciate your work. My hobby is rf engineering & fm broadcasting and I'm currently trying to build a link receiver and mpx (RDS+stereo) encoder on a Raspberry Pi 2 W or Orange Pi Zero 3.
Now the issue I faced: Your RDS encoder is not working. Tried it on a Linux Mint 12 desktop with a VCO-PLL-tx by PCS Electronics. My 384kHz Realtek sound card is not the issue as it works perfectly fine on the same system using Stereo Tool.
Edit: I'm outputting the generated MPX to the sound card. It's definetely set to 192kHz.
Same on a Win10 machine with Airomate: The sound card does generate proper stereo & RDS.
Tried the branch for GnuRadio 3.9 as well as the new version for GnuRadio 3.10 - no luck. QT Frequency FFT shows a correctly generated 57kHz-RDS-subcarrier & 19kHz stereo pilot. Also, I get a sound output on that sound card in GnuRadio - but no RDS.
Checked everything using my Tef6686 - the RDS flag doesn't light up. When using StereoTool or Airomate, it does immediately.
Do you know what's the issue here? Maybe I made a mistake.
