Shortwave Transmitters

High-power shortwave radio

Designing and building a transmitter capable of reaching into the "uttermost parts of the world" was the initial vision of the Technology Centre . After many years of engineering research and design, the result has been the 100,000-watt HC100. Designed and built to operate in demanding environments, the HC100 combines efficient power usage with improved reliability and reduced maintenance, and can automatically change frequencies in a matter of seconds rather than minutes; reaching into parts of the world that remain hostile to the gospel. One of the key requirements has been to keep production costs low, with the total cost remaining a fraction of similar transmitters on the commercial market.

Since the completion of the first prototype in 1989, eight HC100 transmitters have been assembled, installed, and are operating daily in Swaziland, Ecuador, Guam, and Australia. The ninth HC100 has recently been sent to HCJB-Australia to increase its broadcasting outreach and add additional languages for broadcasting into China, India, and other 10/40 window countries where the gospel is most needed. The HC500 is still in daily operation in Pifo, Ecuador.

Low-power shortwave

Engineers have completed the design of a 1,000-watt low-power shortwave transmitter. Since 2001 these transmitters have been shipped to Liberia, the Democratic Republic of Congo, Bolivia, Peru, Mexico and elsewhere, and are proving very reliable.

Digital shortwave

Herb Jacobson, senior staff engineer at the Technology Centre , is working with the DRM (digital shortwave) technical committee.  An upgrade to allow existing HC100 transmitters to broadcast using the new digital shortwave medium known as DRM (Digital Radio Mondiale) is in testing. This upgrade will dramatically improve the typically poor audio quality of shortwave broadcasts to that of local FM radio. Digital radio is the direction for the future, and the Technology Centre is committed to remain current with the latest advances in this area.
