[CQ-Contest] RBN question

[David Gilbert]

I'll say it again ... the number of contacts has almost nothing to do 
with the number of RBN spots.  The RBN spots for UA9YBA are a function 
of who heard him ... nothing else.  It's the number of people who heard 
him that counts, not the number of stations he worked.
