Spidola was a female spirit guide who allegedly communicated with Konstantīns Raudive during his investigations into electronic voice phenomena.
In his book Breakthrough: An Amazing Experiment in Electronic Communication with the Dead, Raudive explained how he communicated with the spirit world through an intermediary, or “helper,” named Spidola. She existed on the other side, operating what she called a transmitting station of her own. Her voice was clearly female, but exhibited the “hissing” and terse language characteristic of other spirit voices.
When wanting to record voices, Raudive would first adjust his recording device until he could hear Spidola’s voice, at which point he would wait until she told him to begin recording. In this way, he would know exactly when other spirits were present.
Coincidentally, or perhaps not, VEF Spidola was the name of the Soviet Union’s first mass-produced short wave transistor radio.
