The Small Radio Telescope (SRT) composes of a 2.3m diameter antenna with a computer-controlled altitude / azimuth drive system. The FFT-based radio spectrometer receiver able to study continuum and spectral line observations in the L-band (1.42 GHz). For example, the 21 cm (1420 MHz) spin flip line of atomic hydrogen can be observed by this telescope which serve as a teaching tool for undergraduates.
