[CQ-Contest] dupe sheets, Op-Aid 6

[Mike Gilmer, N2MG]

I had a ritual when I hosted a series of DX contest multi-ops back in 
the mid-late 80s... I would create a new custom dupe sheet after going 
over last years so I could get the area-per-country layout correct.  
Problem was, even though the sunspots were declining, we kept improving 
our antennas so much between 'tests that some countries' areas never 
were big enough!  There were always many dozens of calls written in 
the margins.  ;-)
