Butler County Amateur Radio Association is a general-interest Amateur Radio Club serving Butler County, Pennsylvania. While club members have varied interests within Amateur Radio, each year the club sponsors ARRL Field Day participation, a club picnic, a swapfest, and a holiday dinner. In recent years the club has sponsored several courses leading candidates to the Technician-class license exam, many Volunteer Exam sessions, and participation in the Butler Jeepfest. The club sponsores the W3UDX 2-meter repeater, and is working toward establishment of a DMR repeater in the near future.
