New to H.F. The contest going on this weekend requires that you exchange signal report and zone number. I looked up the I.T.U. zone and regions chart on the IARU web site to find out what zone I am located in. It looks like I am in zone 8, (Michigan, Oakland County). I made my first contact and was questioned if I was correct with zone 8. It sounded like I had the wrong number. I stopped my contacts with the contest for fear of the wrong number. Am I wrong with the number 8? What would be my zone number? Thanks in advance.
