Hi all:
Just for information.
SWL report of AO-85 during its orbit #456 + 11mins at 09:39 UTC
Location: IN80CP.
Max. elevation during the pass: 7º
RXing with 9 element yagi + mast preamp, horizontal polarization.
No telemetry heard. No beacon heard. Is sat still on COR mode? Usual dificulties to be repeated by the sat. Usual fading. But clear audio (My feeling that much clearer than when the sat is in the standard modes) Very good signal strength (Same feeling... Is this COR mode providing more power than in the standard modes?)

That's a bit weird, isn't it? VK5HI reported telemetry at 6:25 UTC today:

I coincide in the opinion that the audio is clearer without DUV telemetry.

Indeed it seems that AO-85 was in COR mode as it passed over Europe about 11:10 UTC. Listened in SUWS websdr. Several Spanish stations on the transponder, as today is holiday in some parts of Spain.

Just to clear up any confusion about why I uploaded telemetry at 0625utc. AO-85 and AO-73 are currently passing over VK at similar times. My prime focus is the capture of AO-73 telemetry. I had a reasonable capture of AO-85 off the back of my beam on my IQ file. So I replayed two passes around 0625utc, for a total of 35 frames of telemetry. 73 Colin VK5HI

Oh, I assumed that the timestamps on the telemetry where the timestamps when the packet was actually transmitted by the satellite, not when it was eventually decoded and uploaded.
Is there any way of knowing when the satellite transmitted the packet? It seems that one could perhaps use the satellite uptime and number of resets.
Then it seems that the last telemetry uploaded realtime was at Sun, 08 Nov 2015 23:30:36 UTC by VK5KJP (uptime=22007).

Your telemetry has uptime=22211, so it was transmitted by the satellite some minutes later.
The passes *Monday November 9, 00:05 through 00:25 UTC* *Monday November 9, 01:45 through 02:10 UTC* over NA were when presumably the IHU was to be turned on again, so I'm not so sure what happened.
