By the way, John--a handy place to spot check power levels at various dates is here:
http://www.amsat.dk/oz7sat/tlm/view.php?sat=ao51 Just put in the dates you want to see.
And the full telemetry archive is on the AMSAT FTP server, so folks can grab, decode, and and analyze anything they want, for any telemetry that's been collected.

Hi John,
Have you looked to see what power levels we were running at the comparision times? Maybe that's part of it...
The orientation should be "back to the way it was" before the flip experiments. What might be differnet is power budget and therefore signal strength.
Anyhow, it's good to ask and compare notes!

It has been about a month now since AO-51 was commanded back to its normal orientation. But many are reporting that they are having more trouble hearing it now than they did before the first re-orientation.
It does seem to me that some stations that usually hear very well are not hearing that well now. This morning's pass (9Feb2010 1045z) of AO-51 seemed to bear that out. AF6RF, KB1RVT, KE3LB, WD0X?, KJ4CBC, K5QXJ, WB2IOL and YF6BFE were on the pass and with a few exceptions, all were not able to hear at some point during the pass. There are also a few noisy uplink transmissions as well.
The recording can be downloaded at: http://www.papays.com/AO-51_09Feb2010_104452za.mp3 (there are no signals in the first minute of the recording)
Is anyone else having trouble hearing AO-51 as well as they heard it before the flip experiment?
