QEUQIAO (China's lunar relay satellite) at the Earth-Moon L2 point revealing that one can hear data signals from the distance of the Moon and beyond. I tune the audio passband in and out of the data side-band so you can hear the difference.
@coastal8049 That is so very cool! Is it the data signal when you move it to the left?
Btw, to fix your typo, the satellite is named QUEQIAO, and it means Bridge (Qiao) of Magpie (Que), a bridge of love formed by magpies in a Chinese legend.
@kemuri Thanks, I guess I typed it wrong into the log file for the display 🙄
All I can say about hearing the data signal is follow how I move the passband on the waterfall.
@coastal8049 Ahhh I see, the higher pitch sound when you move the band off the tiny bump on the frequency visualization is static noise, and the lower pitch almost waterfall like sound is the signal.
@kemuri this is a type of 'pink' noise kinda. When I move the passband you can hear the pitch change. This signal is decodable at these SNRs.
