Radio Silence: The Bulgarian Who Jammed RFE/RL During The Cold War

On July 4, 1950, Radio Free Europe made its first broadcast, transmitting a program to communist Czechoslovakia. But over the decades that followed, the news organization's broadcasts were not always heard loud and clear by audiences in communist-controlled Central and Eastern Europe. Ahead of the 70th anniversary of that first broadcast, RFE/RL's Bulgarian Service was given a tour of a Cold War-era jamming station by an engineer who once worked there.
