HCJB's Gospel Sound Truck was a mobile radio station equipped with a generator, receiver, transmitter, antenna and loudspeakers that proclaimed the Gospel in town squares all over Ecuador.

With Permission from the President

The success of using “radio” to attract crowds from a railroad boxcar inspired Clarence Jones and D.S. Clark to build the Gospel Sound Truck.

A 1936 truck was outfitted with a radio, portable transmitter, antenna, generator and loudspeakers to “broadcast” the Gospel to anyone within earshot of the truck.

After receiving some opposition, Clarence Jones managed to get a permit signed by Ecuador’s president that allowed them to broadcast freely from any public place in the country.

Ecuadorian pastors discipled by Christian & Missionary Alliance missionaries D.S. Clark and Reuben Larson also had an integral role in the sound truck ministry.  The team played recorded music and live HCJB radio broadcasts as well as in-person evangelistic messages and testimonies. The team would also hand out Gospel tracts and portions of Scripture to anyone who wanted them.

The mission acquired a large tent that allowed them to hold week-long evangelistic services that would lead to the starting of numerous churches around Ecuador.
