Well, I just finished the 03:00z pass, setting due North through the trees.  
I did manage to make one contact (thanks WA6FWF!), but man, I've got work to 

S-band downlink was pretty crummy.  Lots of QSB - more than I remember on 
other modes, and more than I would have expected given my AO-40-capable, 
circular polarized 24x30 inch grill with preamp and all that.  I know I've 
had better results in VS before.  But the big surprise is that my shiny new 
18 turn helix seems to perform much worse than the thrown-together 9-element 
quagi I had up for LU on field day.  No full quieting, and real spotty when 
I did get in.  I guess the only good news is that I was able to work the 
bird a lot lower in elevation than on LU for some reason.  Go figure.

Next pass in about an hour, out to the west.  Will give it another shot.

Good downlink but no other stations heard
on the last pass (2154Z - 2202Z)  of AO-51
as it passed south to north up the middle of
the Atlantic at max elevation of 3 degrees.

10w from IC910H to 4 x 9 turn (WIMO) Helix.
BBQ dish and K5GNA downconverter.
