Televangelist Peter Popoff's wife, Elizabeth, was seen canvassing the crowd before a show, and it was later noticed that Popoff was wearing a hearing aid, which is odd for a faith healer. In 1986, James Randi and his associate Steve Shaw, an illusionist known professionally as Banachek, organized Project Beta with technical assistance from the crime scene analyst and electronics expert Alexander Jason. Using computerized radio scanners, Jason was able to demonstrate that Popoff's wife was using a wireless radio transmitter to broadcast information that she and her aides had culled from prayer request cards filled out by audience members. Popoff received the transmissions via an in-ear receiver and repeated the information to astonished audience members. Jason produced video segments interspersing the intercepted radio transmissions with Popoff's "miraculous" pronouncements.
