Raudive Diode Receiver
Konstantin Raudive (Pronounced Row-dee-vay) was a Latvian psychologist and parapsychologist who studied under Carl Yung. In the 1960s he carried out many EVP experiments and devised a method where the microphone was replaced with a germanium diode device. He discovered using a Germanium Diode plugged into a recorder instead of a microphone helped improve the quality of the voices and give a much improved EVP experiment. The Design of this product has be improved with a removable aerial which prevents accidental breakage.
This compact unit has a small metal body and a detachable telescopic antenna, it is fitted with cable and a 3.5mm jack plug which fits microphone sockets for hand held recording devices.
This device was intended for paranormal research in the ITC (instrumental trans communication) field. the concept is to plug it into your recording equipment via the microphone socket, conduct your EVP sessions and examine the results. The Raudive Diode Receiver will not record audio as you have heard it but rather a soft white noise which is a means provided for spirit manipulation or as a carrier for spiritual voices. I prefer to use this either in short bursts say 3 or 4 minute samples at a time or as a background monitor which will run throughout the entire vigil. If you like me examine data on a computer the you will see the flat sound waves and easily be able to see any disturbance in the sound wave.
