In 1984 Nippon Electric Company constructed an INTELSAT antenna at 3,370 meters above the sea level on the Peruvian Andes. Entel Peru, the Peruvian telecommunications company, managed the antenna station until 1993. This year the government transferred the station to a private telecommunications company, Telefónica del Peru. Since the satellite communications were rapidly replaced by transoceanic fiber optics, the beautiful 32 meters parabolic antenna has been unused since 2002.. In cooperation with the National Astronomical Observatory of Japan we began to convert the antenna into a radio telescope. Because researches on interstellar medium around Young Stellar Objects (YSO) will be able to observe the methanol masers that emit at 6.7 GHz, initially we will monitor the 6.7 GHz methanol masers and survey the southern sky. An ambient temperature receiver with Trx= 60 K was developed at Nobeyama Radio Observatory and is ready to be installed. The antenna control system is the Field System FS9 software installed in a Linux PC. An interface between the antenna and the PC was developed at Kashima Space Research Center in Japan. In the near future we plan to install the 2 GHz, 8 GHz, 12 GHz and 22 GHz receivers. The unique location and altitude of the Peruvian Radio Observatory will be useful for VLBI observations in collaboration with global arrays such as the VLBA array for astronomical observation and geodetic measurements. For Peru where few or almost no astronomical observational instruments are available for research, the implementation of the first radio observatory is a big and challenging step, and foster sciences at graduate and postgraduate levels of universities. Worldwide telecommunications antennas possibly are unused and with relative few investment could be transformed into a useful observational instrument.
