Since 1961, STC has been the primary service provider for Motorola in the Rio Grande Valley. The company was founded by Harry Ewing and Mike Haden. They opened a small shop on north 10th street in McAllen with B. J. Ewing handling the books. In those days with radio was our primary focus, vacuum tubes and dyna-motors were the latest technology and frequently required service. There were no repeaters, no trunking system and a portable radio was larger than a lunch box. Each company, police or fire department owned their own base station and short tower. Interference, skip non-private channels were accepted as normal. STC has grown over the years. We now have two locations adding Brownsville in 1990. We now service the Public Safety community throughout our primary area of responsibility for Cameron, Willacy, Hidalgo and Starr counties.
