HCJB, "The Voice of the Andes", was the first radio station with daily programming in Ecuador and the first Christian missionary radio station in the world. The station was founded in 1931 by Clarence W. Jones, Reuben Larson, and D. Stuart Clark.[1] HCJB now focuses on Ecuador with unified programming on FM at 89.3 MHz in Pichincha, at 92.5 MHz in Manabí, at 96.1 MHz in Tungurahua and Cotopaxi, at 98.3 MHz in Esmeraldas and with separate programming on AM at 690 kHz.[2] Broadcasts in Spanish and indigenous languages on 6.05 MHz (1 kW), continue on an intermittent basis with a new solid state transmitter which in 2017 replaced an older (5 kW) transmitter. These broadcasts were not listed on the HCJB English website as of February 2016.


Radio station HCJB started as the vision of Clarence Wesley Jones (1900–1986),[3] a musician, graduate of Moody Bible Institute, and the son of a Salvation Army minister. Following his graduation from Moody, Jones worked under evangelist Paul Rader and was part of the founding staff of the Chicago Gospel Tabernacle where Jones assisted in leading music, working with youth and overseeing Rader's weekly radio ministry called "WJBT" (Where Jesus Blesses Thousands)[4]: 31  Impressed by the impact Rader's radio ministry had made, Jones felt called to establish missionary radio in Latin America. As a result, Jones traveled to Venezuela, Colombia, Panama and Cuba on a seven-week trip in 1928 looking for a suitable location for his envisioned radio station, but was unable to obtain the necessary government permits.[4]: 54  Back in Chicago nearly two years later, Jones met Christian & Missionary Alliance (CMA) missionaries from Ecuador - Reuben and Grace Larson, John and Ruth Clark and Paul and Bernice Young. These missionaries encouraged Jones to consider Ecuador as the place to start his missionary radio station.

As the first step in fulfilling his vision, Jones needed to obtain a contract of approval from the Ecuadorian government for setting up the radio station. Reuben Larson and D. Stuart Clark, along with Ecuadorian lawyer Luís Calisto, worked to procure the initial contract. On August 15, 1930, the Ecuadorian Congress approved a bill which granted Jones a 25-year contract to operate a radio station in the country.[4]: 67 

As with all countries having a governing body over broadcast operations, the call letters HCJB were obtained through the government of Ecuador, beginning with the internationally allocated prefix for Ecuador's broadcast stations (HC). Station co-founders Jones and Larson advocated for, and were granted by the government, call letters that were an acronym indicative of the stations' agreed upon purpose. The result was Heralding Christ Jesus' Blessings. In Spanish (one of the original broadcast languages of the South American station) the call letters represent Hoy Cristo Jesús Bendice.[4]: 77 

Jones incorporated the World Radio Missionary Fellowship, Inc. (WRMF) on March 9, 1931 as a non-profit entity and overseeing organization over HCJB. Jones was also the non-profit corporation's first president. The corporation's first officers were Adam Welty as treasurer, Ruth Churchill, secretary, and Lance Latham and his wife, Virginia, along with Howard Jones and Reuben Larson serving on the board of directors.[3]

HCJB's first broadcast on Christmas Day, 1931 had the potential of being heard by the six radio receivers capable of receiving the program and existing in the country at the time.[5] The inaugural program was broadcast in English and Spanish from a studio in the Joneses' living room and powered by a 200-watt, table-top transmitter. The antenna used was a simple, single wire antenna strung between two makeshift telephone poles. The broadcast lasted 30 minutes.[6]

Frequencies, QSLs, and programming[edit]

The grounds of radio station HCJB in Quito, Ecuador

Initially, HCJB only broadcast programs in English and Spanish. In 1941, however, live programs were added in Russian, Swedish and Quichua. By 1944, the station had aired programming in 14 languages including live programs in Czech, Dutch, French and German. Programs in languages such as Arabic, Italian and Hebrew were recorded elsewhere and sent to Quito on large acetate coated aluminium transcription discs. By 1967, live programming would be added in Portuguese and Japanese.

Following the first years of HCJB's broadcasts on 50.26 meters (5.986 MHz), the shortwave frequencies utilized by HCJB for its broadcasts from Quito were 6.05 MHz, 9.745 MHz, 11.775 MHz and 15.155 MHz.[7] As the station's transmitting power increased, shortwave radio enthusiasts in North America started receiving the station's broadcasts, submitting reception reports in order to provide the HCJB engineers feedback on the station's signal strength and quality.

Since a popular practice in the hobby of shortwave radio listening was to request a QSL card, HCJB started creating its own QSLs in 1932. By the 1970s, the station was one of the most powerful and most readily received shortwave stations. HCJB was heard around the world and received hundreds of letters each week with reception reports from shortwave DXers. The correspondence department of HCJB would respond in kind to its listeners with QSL cards and Christian tracts. As requests for QSLs became more frequent, HCJB missionary and radio engineer Clayton Howard suggested a shortwave listeners' club be created. In 1974, the Andes DXers International, (or "ANDEX") began. Members would receive a membership certificate and membership card with the member's name and individual member number, along with Howard's signature. A monthly bulletin, (later bi-monthly) was sent to members.[8] ANDEX eventually had a membership in the thousands and continued as a service of HCJB until 1996.

Since the station's first year of broadcasting, staff members produced the HCJB's own original radio programming. HCJB's original programming has ranged from programs completely in Quichua (the primary language of the people of the Andes), Andean-music programs, Christian music programming, talk and mail-reading programs featuring mail received from listeners around the world, Bible study and teaching programs, and programming featuring information about shortwave radio listening. Some of the most popular HCJB-produced programs over the years have been "Morning in the Mountains," "Musica del Ecuador", "Musical Mailbag," "Happiness Is" and "DX-Partyline." "DX-Partyline" was hosted from its inception by HCJB missionary Clayton Howard and his wife, Helen. The program was heard for more than 40 years, twice a week, and included the reading of letters from shortwave listeners around the world as well as DX and reception reports sent to the station. "DX-Partyline" also included shortwave radio listening tips, information on antennas, and equipment reviews. Programs not produced by HCJB were also broadcast from the Quito station.[9] Typically of a religious nature, some of the non-HCJB produced programs broadcast from the station were the Pacific Garden Mission's "Unshackled!", the Billy Graham Evangelistic Association's Hour of Decision, the Salvation Army's "Wonderful Words of Life" and Moody Bible Institute radio station WMBI-FM's "Nightsounds" with Bill Pearce,[10] among many others. Much of HCJB's original programming also included music recorded, produced and performed by HCJB missionaries.[11] Much of the HCJB-produced music broadcast on the station was also available on LP record albums and later on cassette tapes.

In December 1995, Radio Netherlands the Media Network programme visited the transmitter site at Pifo with two members of the HCJB production team. The programme can be found in the Media Network vintage vault. The Media Network Vintage Vault 2023-2024: MN.07.12.1995 - BBC World Service Cuts announced and visit to HCJB Quito Ecuador

  • 1990 - The first HC-100 (100,000-watt) transmitter goes on the air in Quito, Ecuador. Since that time eight more HC-100s were built and put into use by the World Radio Missionary Fellowship, Inc. in Ecuador, Swaziland and Australia.[citation needed]
  • 1992 - A radio station in Bukavu, Zaire is "planted" by HCJB. The station used a portable FM transmitter designed and built by staff at the HCJB Engineering Center.[citation needed]

HCJB Global Technology staff members are involved in research, development, training and technical support for AM, FM and shortwave radio stations as well as satellite distribution and satellite-based Internet services. In recent years they developed station automation systems and a fixed-tuned, solar-powered SonSet radio that can be pre-tuned to pick up a specific Christian radio station. HCJB Global staff have been active in pioneering equipment and software for a form of digital radio broadcasting called DRM.[citation needed]

End of long-range broadcast[edit]

After nearly 80 years of shortwave broadcasting from Ecuador, Radio Station HCJB ended its extensive worldwide shortwave transmissions on 30 September 2009.[16] The international transmitter site in Pifo was dismantled to make way for the city of Quito's new airport. According to HCJB Global President Wayne Pederson, the change was made because

“the way people consume media has changed, so we have the opportunity to change to delivery systems such as satellite, AM/FM and the Internet. The closing of shortwave in Latin America is strategic because of the planting of local radio stations across the region and around the world. These stations are staffed and programmed by local Christians who can speak to the culture in their own communities.”[17]

HCJB Global's focus is now on “radio planting” – assisting local Christian ministries in beginning implementing their own Christian radio ministry. Worldwide, more than 350 local stations have been assisted in this type of endeavor, including nearly 60 stations in Latin America alone. Although the historic station and transmitter sites in Ecuador will no longer operate on the shortwave bands, Shortwave broadcasts continue from HCJB Global Australia's site in Kununurra,[18] Australia and from commercial broadcast sites and partner ministry broadcast sites around the world.

HCJB's broadcast from Mt. Pichincha, near Quito, can still be heard on 6 050 kHz with Spanish and indigenous languages of Ecuador. The double dipole (CT2/1/0.3) antenna [19]: 4–5, 17–18  is designed to cover only Ecuador, but the 5 kW signal is heard worldwide from time to time.[20] After replacement of the 40 year-old 5 kW transmitter with a new 1 kW solid state transmitter in 2017, it became even more of a challenge for DX listeners, but is still heard within Ecuador.
