The Radio Society of Tucson (RST) is a 501(c)(3) charitable organization that focuses on “Communications For All” by actively supporting a variety of Amateur Radio activities which are of interest by its members.

Club members support many Public Service Events, Emergency Communications, and VE License Testing. The club regularly participates in the annual ARRL Field Day Event. In addition, RST is the only club in Tucson and Southern Arizona to actively and uniquely support Special Interest Groups that include Radio Direction Finding and Radio Contesting .

RST is the only club in Tucson and Southern Arizona that offers two full stacks of D-Star Repeaters that supplement the area's rather robust vhf/uhf analog repeater systems with a full compliment of digital repeater infrastructure.

Anyone interested in Amateur Radio, licensed or not, is welcome to attend our monthly meetings and participate in our many events throughout the year.
