This is very likely the explanation for my lack of data decoding. If it's only sending two frames at a time, the likelihood of missing data during a transmission is much higher than when the satellite is sending dozens of frames in a transmission.
Thank you.

Hi Steve.
It will send 2 frames every 2 minutes unless the transponder has been activated.
When the transponder is activated you get data while it's in use and for about 30 seconds after the last person finishes speaking
- Same story here in the UK. Lots of passes before dawn, but nobody transmitting- So that usually get me about 12 - 16 frames of data compared to 80 - 110 for a really nice pass.

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!
