PSAT digipeater has been turned off. The spacecraft has entered safe mode now several times due to low power. So we will keep it off until conditions improve. Do not use the PSK31 transponder either.
We were so accustomed to excess power during the previous full sun period that we had evertyhign on… 95 miunte orbit 100% always in the sun.
But now we are in a maximum eclipse period with only 59 minutes in the sun and 36 minutes in the dark. Cleary that is only 61% of the power we had before!
The times of lowest power of course are just before dawn.

Heard a few packets from NO-84 in latest pass (~2315 over EM79) but nothing strong enough to decode. Max elevation was 61 degrees and I would normally decode at least a few packets on a pass like that.

7 is up and running!
It looks like the illumination will get better for NO-84 by late August.
