The annual 13 Colonies special event will begin on July 1 at 1300 UTC and conclude on July 8 at 0400 UTC. Stations representing the original 13 British colonies, plus two bonus stations, will be on the air with 1 × 1 call signs. The event sponsor stresses that participants do not need to work all 13 colony stations to obtain a certificate and do not need to work the two bonus stations for a clean sweep. All HF bands will be in play, with the exception of 60 meters, and simplex on 2 and 6 meters is encouraged. All modes of operation may be represented.
