Hello,
It would be fine to add sendspin support at Muse Radio device. I made a fork of RASPIAUDIO/muse-radio-voice-satellite : GitHub - afer92/muse-radio-voice-satellite at sendspin · GitHub
I also added some preset radio chanels : muse-radio-voice-satellite/raspiaudio/radios.yaml at sendspin · afer92/muse-radio-voice-satellite · GitHub
Regards
