I found that from my QTH in Nebraska, I had to turn the beam north to work 
a Texas station at one point in the contest. That had to be scatter. There 
were others that seemed to be off the short path, but that one stands out.

>A couple of explanations occurred to me:
>-- In this contest, people expect to be able to hear and work weak signals,
>so off-the-side QSOs happen all the time.
>-- Backscatter can enhance sigs in non-favored directions.
>Anyone got any better ideas?  I'm just curious.
