@CitGardens I don't know why I was able to receive suspected to be image data transmission at 7:06 UTC, which resulted the final data transmission ended with Elv. of only 2°. Also, due to the satellite's rotation, the signal was weakened and could not be decoded data.
@CitGardens
Sakura's strong signal was received, but since it was a non-standard AX.25 signal, soundmondem could not display the raw data properly.
The satellite signal is received using a 15ele yagi antenna and the receiver is RTL-SDR
