How accurate does the GPS need to be?  I know GPS are similar but very
different in price.  Some are accurate enough to be used for map making.
But for verification of grids worked, how accurate do they have to be?

Hi David,

I think the photo of the GPS is only necessary when operating from a 
grid boundary or intersection. If you know where you are by using a map, 
and claim only one grid, that is perfectly fine! I know EK34 and 44 
would be new grids for me, so by all means get on the air!
