By the 1950s, the shortwave bands were becoming crowded. For HCJB to be clearly heard around the world, it needed to increase the power of its radio signal. It was decided to add a 50,000-watt transmitter, which was very powerful at the time. HCJB engineers completed construction of this large unit in 1956.

In later years, engineers at the mission’s engineering center in Elkhart, Indiana, would design and build a 500,000-watt shortwave transmitter as well as numerous 100,000-watt transmitters.
