I tried, unfortunately, I wasn’t able to get recognizable sounds out of the “images”. However, it seems perhaps some music SSTV image generator could be made. I found this image that makes interesting and for SSTV unusual sounds: https://files.catbox.moe/vr9yjw.png
Image passed a few times over Robot 36, Robot 72 and PD 50 from speaker to microphone at lowest volume in a room with other noise.
So the capture of RF out is closest, since it’s actually analog modes meant for ham radio use. The noise is just not from RF but audio.
I can hear your neighbors fucking upstairs in this image.
