Objective: To support amateur self-training in radiocommunications including improving amateur operating skills, conducting technical investigations, and intercommunicating with other amateurs around the world, especially IARU member society headquarters stations, using the 160, 80, 40, 20, 15 and 10-meter bands.

Date and Contest Period: The second full weekend of July, beginning 1200 UTC Saturday and ending 1159 UTC Sunday (July 10-11, 2021). Both Single and Multi operator stations may operate the entire 24-hour period.

Contest Exchange:

IARU member society HQ stations, such as W1AW, send signal report and official IARU member society abbreviation as listed on the IARU website at https://www.iaru.org/reference/member-societies/. IARU International Secretariat club station NU1AW counts as a HQ station, and sends “IARU”. Members of the IARU Administrative Council and the three IARU regional Executive committees send “AC,” “R1,” ”R2,” and “R3” as appropriate.

All others send signal report and ITU zone.
