    I’m unsure if that’s a filter, a capture of RF out, or just an OLED smartphone screen after a year of use.

      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.
