These sources collectively explore the history and impact of missionary radio, particularly focusing on HCJB (originally "Heralding Christ Jesus' Blessings"), founded by Clarence Jones in Ecuador in 1931. They detail how HCJB utilized radio broadcasting to spread the gospel message, even distributing receivers and using mobile studios like a "radio rodante" (traveling radio) to reach remote communities and individuals. The sources also discuss the broader evolution of missionary methods and technology, including the importance of medical ministry alongside spiritual outreach, the development of resources like the "lab-in-a-suitcase," and the organization's shift to Reach Beyond to focus on areas where the gospel is less known, while highlighting the significance of partnership and technological innovation in achieving their goals.
