CQ CLASSIC: Bringing Back WAZ (Again)…

ANNOUNCING W.A.Z. • The Zone system of DX has steadily gained in popularity since its inception in 1936. The measure of its achievement is testified by the fact that at the time of its suspension in February 1941 only three stations in the entire world (ON4AU, G2ZQ, J5CC) had worked the forty zones. As a DX “yardstick” the W.A.Z. system offers a more equitable basis of comparison for stations throughout the world. In addition, W.A.Z. eliminates any question of “when is a country not a country?” The DX Zone Map of the world appears on page 46.
