 The next WRTC event was held in the San Francisco, California, USA area in July, 1996, and was organized by the Northern California Contest Club.The format continued to be teams of two competitors each, operating at stations with similar antenna and power restrictions, participating in the IARU HF World Championship, a world-wide operating event that includes both phone and CW operation.A major innovation at WRTC 1996 was the assignment of special-event call signs to each of the competitive stations.
