In 1978, residents in the city of Eugene, Oregon, reported hearing a radio frequency pulse that was 500,000 watts — 10 times the FCC’s AM licensed limit.  The powerful radio signal was monitored in several homes and also in the air some 3,000 feet above the city.

Shortly before the Register-Guard printed the story, a middle-aged Eugene man, Walter Deposkey, came down with mysterious symptoms remarkably similar to those attributed to microwave sickness. He noted a strange vibration emanating from within his home. He heard voices. He could not sleep. Truthstream Media explores the still unsolved mystery surrounding the Eugene Signal.
