Hi Greg.
The transponder was on during the last pass over Europe. As far as I know the team in The Emirates have left the satellite in a mode where the transponder is on in eclipse.
So, it should be on for tonight's passes over North and South America.
The signal every 5 seconds should show up as 2 lines lasting 700mS. The telemetry data is transmitted for 4.3 seconds between each burst of tones. (but it sounds just like noise.)
All reports appreciated. And videos ! Thanks PY5LF

Oh, wait...
Just ran Fabricio's recording through fldigi, and I see TWO lines (tones) during the 1 second pulses, each looking about like what I saw. So, the modulation is really wide, compared to what I am used to seeing. Didn't catch that during my pass. Will check again next time.

Perfect! Thanks for the explanation of what the telemetry sounds like. That matches what I hear.
Will give the transponder a try... Next pass 8:40pm local, 40 degrees.
