The power budget of the satellite is not able to sustain both the digipeater and the PSK31 transponder throughout all parts of the orbit. When the battery voltage drops below a certain threshold, the secondary mission of the satellite, the digipeater, is shut off. The primary mission, the PSK31 transponder, remains operational.
When the eclipse percentage of the orbit drops, one of the command stations will turn the digipeater on again.

NO-84 seems to have its ears turned off for the few days. Anyone know what's happening there?
