"The device is supposedly a reproduction of an ancient communication instrument - one form (there are several others) of what Dick Shaver called 'telaug' in his writings. Its main use by ancients was to communicate telepathically with others on the same 'here-living' plane. My information says, however, that it can also be used to communicate with entities on other planes, if properly tuned."

If you dare, an account of psychic contact and a schematic for the Hidden World receiver from the notorious Shaver Mystery, detailed in full: #B0084, "Two Inventors Return & Project Hermes".
