Beaches on the Air (BOTA) is an award scheme for radio amateurs and shortwave listeners that encourages portable operation from beaches. There are awards for activators (those who operate from the beaches) and chasers (those who contact activators from home or elsewhere). BOTA can be operated from any country or region across the world. Each country or region may have its own manager, who, among other things, co-operates in the preparation of the list of recognised beaches within that country or region, which must be approved by the central BOTA management team. Activators and chasers accumulate points with each QSO. Their total score is calculated by adding the square root of the number of QSOs made from each different beach (activators) or with each different beach (chasers). Activators can activate, and chasers can chase, the same beach as many times as they wish and they will always earn additional points, but there will be decreasing returns to activating the same beach due to the square-root rule, which encourages the exploration of new beaches. Certificates are available for various scores, both for activators and chasers.
