15:30 UTC, 17:05 UTC, 18:40 UTC nothing heard 🙁

John, KE5JTG: We had set the clock, that goes for today too. We will be trying again about 19:30 UTC tomorrow. Radio should be back on about 03:45 UTC tomorrow (the 12th) in case you can pick it up again tomorrow.
Last check had us down to less than 230 km, we dropped about 3.5 km yesterday or the day before and the rate is picking up.
