Via a recording with many, many playbacks trying to tune it in.
ZZ Top started playing at 0346, then an ID by an OM at 0349 and three similar waterfall images at 0350. And it was gone.
35452. Why "2"? Because even tuning down to 0.001, it was never quite tuned-in. I think that the broadcast had some inherent distortion.
No idea what the images were. A flower, maybe? A bug? A stylized balloon?
