Congratulations,

I tried for many passes without success this side.

From SatPc32 with nasabare TLE it is now at 345Km altitude, but my experience following birds decaying is that TLE are not reliable during re-entry thus using a OMNi antenna (and manual frequency adjust) has proven to be more reliable.

Would be interesting to know who will capture the last signal (agonizing whisper) of SO-121. The race is open but also this data may be interesting for the SO-121 team.

Hello, DE JI1IZR/Masahiro.

I listened to HADES-D(SO-121) from 13:32 to 13:42UTC today, October 27th.

I caught the signal but I could not decode on real time. I tried to decode after the pass with the recorded sound, and succeeded to get the result as below. I send to share the informtation here.

The time is revised as JST (UTC+9) when the every signal ended.
