Celebrate the spirit of the Southwest and the iconic cactus that defines its landscape. This amateur radio special event brings operators together across the country to connect with six featured CACTUS call signs — K7C, W7A, N7C, K7T, K7U, K7S — plus two bonus stations, K7RST and AK7AZ. Participants can enjoy friendly contacts, unique exchanges, operator schedules, QSL cards, certificates, and more. All details, resources, and updates are available at cactus.k7rst.net.
