On the night of August 31, 1983, Bill Whitacre was given an urgent task: A South Korean commercial airplane had been shot down by the Soviet Union over the Sea of Japan, and VOA needed to inform its audience about the breaking news.

From Ethiopia to Vietnam, there are
75 RMSs around the world. Each RMS
consists of an antenna, a radio and a
computer attached to the Internet such
as the one pictured here.

“We stayed up most of the night to broadcast it in Korean and English,” Whitacre remembered. “It was one of the most exciting and memorable moments of my career.”

Whitacre, who today serves as monitoring chief for the International Broadcasting Bureau (IBB), has been fighting against jamming for more than 30 years. “What has remained constant is jamming,” Whitacre said noting that although the Cold War has since ended, there are still many countries that try to jam our broadcasts.

You can hear what jamming sounds like today at this link.

One technique to combat jamming, Whitacre explained, is to put the programming on multiple frequencies as it is “more difficult for a country to block everything.”

The Monitoring Data Entry System helps
monitors around the world determine the
signal strength, degradation, and signal
merit, with numbers from one to five.

IBB also works to employ a wide range of media to get our message heard, specifically transmitting audio through satellite radio, which can be harder to jam.

From radio to satellite to the Internet, for Whitacre, the mission remains the same. “It’s all about delivering the best information with the best likelihood of reaching the audience.”
