The Tesla Spirit Radio is more than just a crystal radio circuit. It’s a sound maker that plugs into a computer and makes sounds by responding to electromagnetic fields or light sources in real time. This paranormal research device is many things in one. As a crystal radio set, it is inherent that those frequencies associated with EVP have been captured. Much like the Raudive’s Crystal Diode Receiver but with specialized Tesla coil antennas and a variable capacitor. The use of an amplifier is highly recommended as the TSR has no power of its own. Use the Tesla Spirit Radio as you would a microphone, plug directly into your media OR into an amplifier and then to the media.
