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?

Equipment as follows:

Icom IC-910H
Gulf Alpha  2M/70cm dual band yagi.  2M->6 element 70cm->8 element antenna

LVB tracker box connected to a Yaesu G-5500 Az/El Rotator controlled by 
Ham Radio Deluxe.

In HRD I set the following:

Rx - Center of 145.930 USB
Tx - Center of 435.750 LSB

I set it to control doppler on *both* freqs.
I am pulling the keps from Celestrak now.

This morning's pass was to North->South and to the West of my 
location(FM26au).  I noticed that the Rx was always being set lower than 
the center freq, and the Tx was lower before max elev and higher after 
Max elev.  I had about a 9min window.  About a 1/3 of the way into the 
pass I thought I heard some garbled voice.  In the last 1/4 of the pass 
I definitely was hearing some CW.  I can post the recorded .wav file if 

Would greatly appreciate any help.
