Nobody has allowed for the fact that the compass itself isn't perfect! It has some "deviation" from the correct direction,and that usually depends on the indicated direction. Here's the full story...

Well, I think the report IS scientific! It isn't complete (and the authors admit that) in that it doesn't compare a large number of paths, with a large number of ionosperic conditions. It does indeed

I calculate under 1.25 cubic yards for that hole. You're going to have a LOT of concrete left over. 3' x 3' x 6' is two yards. 73, _______________________________________________ See: http://www.msco
