HCJB Radio, based in Quito Ecuador, was one of the earliest Christian shortwave stations, founded in the 1930s. Its powerful transmitters broadcast Christian programming across Latin America and beyond, combining evangelism with technical innovation.

HCJB major works included multilingual Bible teaching, music, and health education programs transmitted via shortwave. Its pioneering use of international radio influenced mission agencies and helped shape the concept of global Christian broadcasting.
