The DXZone merges amateur radio and Internet, since early internet days. Established in 1996 as a radio-related-mailinglist, has registered its domain name in 1998. Main goal is to review and promote ham-radio web sites, classifying them in categories. The DXZone is managed by ham radio operators with ham radio operators in mind.
