My https://uplink.satcom-70.com/ has changed.
Now playing a sound, and asking for a code.

Calibration, huh? Where’s Garrus when you need him?
Pretty sure we’re supposed to run that sound through something, but I don’t have any audio editing software whatsoever on my machine.
facepalm
lol
Here we go! 
I was hearing a loud musical boom. Like something metal being dropped in an empty cave. Creating an echo. Now not hearing anything. Hmmm. Now hearing just empty white noise. Like on the waking titan background wind.
I wonder if the noise I heard was timed to the satellite passing overhead. What does anyone else think?

Realised that in our day and age you don’t have to have audio editing software installed, since there’s a web-app for just about anything. Took a peek at the spectrograph, but nothing immediately apparent there. Would have been too easy, I guess.
Unfortunately I can’t upload MP3 to the forum, so you’ll have to convert it yourself. Here’s a short instruction on how to get the audio from an MP4 with VLC:

And here’s a spectral analyzer, in case anybody wants to have a look for himself:

I’ve extracted the sound to a WAV file. I’m fooling with it now. Sounds a bit like speech, heavily pitch-shifted.

Is it reversed? Could be something very simple? I dunno. The satellite moved further south from my location so maybe that’s why the sound dimmed for my uplink mid play.

If you pick a logarythmic scale, there’s letters and numbers in the spectrograph. Very difficult to make out though, might just be an artifact.
Edit: After some more staring, I’m pretty convinced those are just artifacts that happen to look like occasional numbers or letters. Not an unusual thing in a spectrograph…

The video has “no-signal.mp4” in it. Does it mean we need to enter a code when the satellite is near us so the video will change?

Yeah, the sound in the uplink app just changed to no-signal for me too. Interesting! Trying to correlate to the satelites position.

thank you for posting. The pitch is too low to be picked up by my sorry phone speakers, lol.

That wasn’t the sound I heard I’m sure I heard more of a sound at the start on my uplink attempt. I wonder if I have to wait until the satellite passes close to my location again to hear it more clearly. I had no idea how to record the thing. Sorry!
It might be the sound I did hear but it is now very very VERY faint. I’ll have to wait for the next satellite pass for it to increase in volume. Perhaps someone under the satellite can hear it more clearly?
I can confirm that the satelite was moving away from my location when the signal was lost. It wasn’t very close to begin with, so it can’t be too sensitive.
It might be we’ll be getting different sounds for our respective proximity to the satelite, and that we’ll only be able to make out what we need in the soundfiles at close to max signal strength. Anybody having a close pass anytime soon?
To break the fourth wall for a moment, methinks our “synchronisation” last week was to test how close we could get to not make this too easy or difficult.

I’m now hearing a different sound. Clearly it changes. Satellite is a LONG way from me right now.

When I heard the sound clearly. Or at least at its clearest the satellite would have been above my location about five minutes before at 21:45. That explains why the sound faded so quickly, it was heading south. You’re right I think @jedidia

Ok, let’s look at this pragmaticaly (which I hope won’t be considered cheating):
The soundfiles are in a public AWS S3 bucket, and it seems they’re handed out without signed URLs (i.e. they won’t expire. Personally, I’d have handed out signed links with a ttl of no more than 5 minutes for this, but nobody’s perfect). They are accessible once we have the links. So post the links to the videos you get, and the approximate distance to the satelite. Somebody can collect them so we know when we get which signal.
I’ll start (also make sure you preformat your link, so we can see their names):

Didn’t pay attention to distance at the time, but from backtracking the satelites ground track, I’d say it was received somewhere within 2000 km.

Get the link!! 
Also, how far is the satelite from you right now?
Huh… You in australia somewhere?
