Baseband recording (cut with SDRAngel using FileSink)
When modulated, it looks like Orbcomm mobile telephony, but in that case the data bursts happen more often and there’s no visible carrier.
I also didn’t find anything corresponding in the Happysat’s Deadsat list.
What could it be? Zombie Orbcomm satellite or something else?
I just realised you already said it looks like the Orbcomm signal in the post, sorry about that! I completely missed it when I made my comment.
