The annual Original 13 Colonies Special Event will mark its 10th anniversary this year. The event gets under way on July 1 at 1300 UTC and runs through July 8 at 0400 UTC. Event Manager Kenneth Villone, KU2US, reports that 127,132 contacts took place during the 2017 13 Colonies event, down from 139,772 in 2016, owing in part to poor band conditions.
Special event stations with 1 × 1 call signs will represent the original 13 US colonies, plus bonus stations WM3PEN in Philadelphia and GB13COL in Durham, England. Each special event station will have its own QRZ.com profile page. Participating stations try to contact all 13 Colony Stations plus the two bonus stations. Call signs and their respective states are K2A, New York; K2B, Virginia; K2C, Rhode Island; K2D, Connecticut; K2E, Delaware; K2F, Maryland; K2G, Georgia; K2H, Massachusetts; K2I, New Jersey; K2J, North Carolina; K2K, New Hampshire; K2L, South Carolina, and K2M, Pennsylvania.
