Tried to work the 1201Z 06AUG2011 pass of ARRISSat-1 from FM26 this morning without much luck. I have been successfully working the FM birds for a while but this is my first attempt with a linear bird. I was wandering if someone with a similar setup could verify my settings?
Is it possible as the analog transponder that multiple signals on the uplink reduce the downlink signal up to a point where we are unable to hear anything? As some are reporting using very low power i guess they where probably alone when they made their transmission through the transponder?

I recorded the transponder downlink band on my funcube dongle while testing the transponder, and had a chance to listen to the result several times. It doesn't seem that the telem or FM signals are measurably less powerful at the times when a bunch of us got through on the transponder.
I can make the HDSDR data file available to whoever would like to look over it.
