10 GHz & Up


New scoring rules in effect!

Distance point multipliers for each band have been added to encourage contacts on the higher microwave bands. Contacts on bands higher than 10 GHz will now accrue greater distance points. In addition, single-band "Best DX" and single-band "Top Score" certificates or endorsements will be awarded for each individual band (Individual single-band top scores are to be based on distance points only). See the contest rules at for more details.

Contest Objective: For North American amateurs to contact as many amateur stations in as many different locations as possible in North America on bands from 10-GHz through Light. Amateurs are encouraged to operate from more than one location during this event. See the detailed rules for restrictions.
