I usually have a rather jaundiced view of UFO 'contactee' claims, regardless of the country in which the claim is made, but there's something about the story told by Prof. Rodolfo Paredes (in the report provided by Prof. Ana Luisa Cid) that triggered a recollection. Whether or not Paredes is really in contact with 'beings from Jupiter' is debatable, but the fact that they endeavor to make contact through his radio signal, it is unclear if Prof. Cid meant a 'ham radio' frequency or something else, is very interesting. In the late 1970s, Puerto Rican UFO researcher Orlando Rimax played a recording of an alleged alien transmission on his Otros Mundos broadcast, which aired every Sunday morning in the city of San Juan. The recording could have been a hoax, naturally, but the heavily distorted voice of a being calling itself 'Omicron' was definitely disturbing. It had a quality often associated with recorded sounds involving hauntings and paranormal goings-on, even though the entity professed an interplanetary origin, and they always do.
