Arecibo

The document summarizes a meeting at the Arecibo Radio Telescope in Puerto Rico. It describes how the author's interest was sparked by an article about using the telescope for Earth-Moon-Earth communications. After his wife expressed interest in visiting somewhere warm, he contacted the president of the Arecibo Amateur Radio Club, Angel Vazquez, who invited them for a tour. During the tour, Angel showed them around the telescope and provided details about its 1,000 foot wide reflector, 900 ton platform, 1 megawatt transmitter, research areas, and operations run by the National Astronomy and Ionosphere Center.
