Philip E. Barnhart (Ohio State University Radio Observatory; NAAPO)
The Ohio State University 110-meter radio telescope is gone. Designed and constructed during the 1950's by John Kraus, the instrument operated in survey mode until December 1997. Following the cessation of Federal support in the early '70's it was operated by volunteers in a variety of programs including detailed scans of selected areas, mapping of hydrogen clouds, SETI and a repeat of the earlier all sky survey.
Following the 1983 sale of the land upon which the telescope rested the volunteer group continued the SETI and continuum survey through 1997 when the lease arrangements were terminated. The site is now occupied by a golf course fairway and green.
Some programs begun during the past 25 years continue under the volunteer organization (NAAPO)founded 15 years ago are continuing. Currently the group is engaged in an effort to develop a new technology, all-sky radio telescope (ARGUS) projected to increase the efficiency of large aperture radio detection systems by a factor of 100,000 to 1,000,000.
