VO-52 without signal

Since yesterday, February 28, none of the reporting radio amateurs has caught a signal from the VO-52 satellite. The VO-52 transponder is among the favorites, because it is characterized by good sensitivity and strong signals on the downlink. It would be a shame if he stopped talking, because sometimes only the veteran AO-7 works in the same linear mode (70cm uplink/2 downlink). However, the latter is dependent on the lighting of solar panels and operation is more difficult.
