RB is a non-profit, educational, public radio network aimed at serving primarily underserved and underrepresented Latinos, as well as to other minority communities, living in the United States.

Two years later, on August 20, 1979, the Federal Communications Commission (FCC) approved Radio Bilingüe's application for its first station, KSJV 91.5 FM in Fresno.

Its 16,000-watt transmitter, located on Eshom Point in the Sierra Nevada, had the capacity to reach the Chicano and Mexican community living in the Central Valley of California between the cities of Merced and Bakersfield.

Radio Bilingüe began featuring public-affairs shows focusing on farmworker issues in addition to musical content.

The station would also broadcast forums and call-in shows on various topics, such as immigration reform, pesticides, labor law, and bilingual education.

In addition to the expanded U.S. coverage, Radio Bilingüe also began reaching Latino communities in Puerto Rico, in various states across Mexico, and in Vancouver, Canada.
