I tried to catch the 1005 UTC pass of AO-85 this morning for data collection. I figured with an 88 degree elevation I couldn't miss. It's perfect for my eggbeater antenna. But, using HDSDR and Foxtelem, I only saw about 3 or 4 short transmissions spread out over the whole pass. I didn't decode any data.
Does AO-85 only transmit slow DUV when there are voice transmissions? Were the short transmissions that I saw the "fast data" stream? Was anyone on voice on AO-85 this morning?
Thanks for your help!

Steve,
Sometimes everybody sleeps in, and you will see only the periodic, short beacons, which does include DUV telemetry. Part of the energy management system. My station was running while I was sleeping, and did capture a few blocks, but I have beams, etc.
