Developed and hosted by a team of Seattle-area contesters, the first WRTC was conducted in 1990 at the same time as the Goodwill Games. WRTC-1990 was independent of the Games but brought contesters together from around the world in the style of Olympic athletic events. Also like the Olympics, WRTC-1990 had significant cultural aspects, emphasizing camaraderie and social events. The social aspects were carried forward into later WRTCs and have become a significant element of the event. The Seattle WRTC was the first time that contesters all competed from the same general location in a world-class event, rather than from their home stations. Minimizing the geographic variation unavoidable in a world-wide competition, WRTC enabled operators to compete on the basis of team skills in a common setting.
