Adolf Homes was an independent ITC experimenter and received both audio and imagery through radios and his television set from the late 1980s until his passing. He received contact from his colleagues Friederich Jurgenson and Konstantin Raudive.
This video shows, around the nine minute mark, contact from Konstantin Raudive through direct radio voice, while the experimenter is being filmed. Raudive’s message is delivered in English.
And this video is of a telephone call from Konstantin Raudive to Mr Homes.
