WHRI signed on in 1985 with their first service, Angel 1, covering Central America, South America, and the Caribbean. Two years later, its second service from WHRI, Angel 2 goes on the air, covering Europe, Central and South America.
In 1993, WHRI opened a second station, KWHR (transmitted from Ka Lae, the southernmost point in Hawaii), which provided Angel 3 covering China and Eastern Asia, expanding in 1997 with Angel 4, covering the South Pacific. The license for KWHR expired in 2009.Angel 3 and Angel 4 now transmit from T8WH in Palau.
In 1998, its third station, WHRA, signed on with Angel 5, a signal for Africa and the Middle East. As of November 17, 2009, "WHRA in Greenbush, Maine has signed off the air for good. All equipment has been dismantled. Former frequencies for WHRA have been reassigned for WHRI usage." This is according to Larry Vehorn, engineer for WHRI Cypress Creek, South Carolina via Gayle Van Horn, Frequency Manager, Monitoring Times.
WHRI also operates Angel 6 with a signal primarily for Mexico.
