[amsat-bb] Odd Satellite problem

I am having a problem hearing the downlink of any SSB satellites on 440.  

I've been off the Sats for a couple of years, two or so.  I just rebuilt my
station PC and reinstalled all the apps, specifically, SatPC32, and ARSWIN
and my controller to my G-5500 and 12 element 2-meter and 17 element 440
beams.  I use two SSB pre-amps, one each for 144 and 440, both appear to
work perfectly.  When I click the Pre-amp button on the ICOM-910, I hear the
background noise level increase, telling me the pre-amp is operating.  The
440 receiver appears to otherwise work ok.  

I was able to work VO-52 where 440 was the uplink and was able to get on the
air for one pass of an FM bird, AO-51, where the downlink was 440.  I am no
longer able to hear the usual passband noise of the Sat when as it comes

It is 21:10 UTC and I just finished trying to work FO-29 from CN87 (20:59 to
21:17), and again no luck.  I sent my call out on 145.950, but nothing back.
Checked the ARRL satellite tracking site and it appears I have the correct
keps installed.  I went outside and checked the bearing of the antenna.
Seems ok.  

Anyone have any ideas?  I am stumped.

Doing what I try to do every vacation which is try to spend a little time
back on the birds. I've yet to have a QSO on HO-68. I hear the beacon just
fine. But I just finished my 2nd pass from NJ and was unable to hear any
signals let alone myself coming back on any mode. Did I misread the
operating schedule or am I doing something wrong? MacDoppler told me there
was a good pass to this part of the world are around 21:30 my time. Great
beacon strength but nobody else was home.
