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. 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. 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. 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. Frequencies, QSLs, and programming 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. 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
