Jim McEachern, who was the principal technical leader for the Public Radio Satellite System for its first two decades and was a key planner of NPR’s technical facilities, died March 3 at age 71. He was one of NPR’s first employees in 1971 and worked for the network for 33 years until he retired in 2004. McEachern leaves his wife, Mary E., children Terrance, Elizabeth and Molly, and sister Janet Macidull. The family will hold a celebration of his life Saturday, April, 3, at the Unitarian Universalist Church in Rockville, Md. In lieu of sending flowers, friends may donate to their local public radio stations.
