Looks like NORBY-2 is alive; don’t know if that’s the first to be heard from or not.

Very faint 9k6-looking signals seen around 436.99 on this first (low) pass over the U.S.
Right place / right time for Cubebel-2, but will need more elevation on future passes to decode.

We demodulated an audio file - this is Cubebel-2

Hi @alkysamara and @igor_lomaka welcome in the community!
I’ve added SamSat-ION and scheduled some observations for the first 12h.
I see you use the radio amateur UHF band frequency. Is this frequency coordinated with IARU?
Congratulations! Also the TLE is pretty accurate.
Any idea which satellite is the one next to Cubebel-2? Maybe Nanozond-1, AHMAT-1 or KuzGTU-1.
