Callisto radio spectrometer construction at universiti kebangsaan malaysia [antennas and propagation around the world]

The Compound Astronomical Low-Cost Low-Frequency Instrument for Spectroscopy and Transportable Observatory (CALLISTO) is a worldwide network of radio spectrometers designed for 24-hour solar observation. It is a collaboration among the Swiss Federal Institute of Technology Zurich and numerous local host institutes, spread out around the world. This paper presents an overview of the CALLISTO spectrometer system at the Universiti Kebangsaan Malaysia (UKM). The “Malaysia-UKM” station is installed inside the campus area, at the Permata Pintar School building. In particular, this paper explains the details of the instrument's setup, and reports some of the data observed from this station. The realtime data are available from the e-CALLISTO International Network of Solar Radio Spectrometers.
