Hello, Sanada-san --
Delfi has no batteries on board; it works entirely from its solar panels. It appears that at present it sometimes gets in an attitude, or position, where its panels do not generate sufficient voltage (or current?) and it shuts down. In addition, sometimes the audio quality of the BPSK transmission degrades; I've assumed that this is a related problem.
Often, it will restart half a minute later, so keep listening to the pass.
I believe that this is a problem the control team understands and is going to try to address, but naturally they are being very cautious.
A longer pass helps a great deal with getting used to tuning the signal. Start by tuning for the strongest signal on your s-meter, then tweak it from there. Don't keep moving the tuning around, because RASCAL needs some time to get a lock.

Hello, everyone,
I watched DEFLI-C3 just now, listen to it and try to decode with RASCAL.
During this pass, the sound suddenly went out about 11:27UTC.
The LOS was about 11:32UTC.
I could not decode any data.
What happened?
