[CQ-Contest] IARU HF zones

I don't believe that the precise ITU zone borders are what the contest 
sponsors expect you to use.  If they were, I would be in zone 10, not 
zone 6.  Besides, how could anyone actually know what zone they are in 
if they were close to a line that didn't follow a political border?  
I've seen some pretty detailed official ITU zone maps but I still can't 
determine exactly where the dividing line is as it crosses southern 
Arizona.  Even if I could find the coordinates for the endpoints of the 
ITU boundary lines, I'd have to calculate the coordinates for any other 
point on the line.  I seriously doubt anyone expects us to do that.

Yes, we all should copy what is sent, but when someone doesn't send what 
they are supposed to it creates needless confusion.  In my opinion, you 
needlessly bring that lost QSO rate upon yourself.

I've sent an email to KX9X asking him to clarify this issue for the 
upcoming IARU contest and maybe he will reply.
