What could this satellite be? Seen on 2023-08-26T09:43:04Z in Slovakia at 137.71MHz. Bandwidth when modulated is 8kHz. Signal lasted a little over 4 min. (Full waterfall, baseband recording in post.)

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?
