Abstract

It is shown that real-time FFT techniques used in conjunction with a small telescope can yield useful sensitivity. The suitability of the Crab pulsar as a calibrator is assessed. The mains frequency modulation in the night sky above Perth is clearly discerned, with several harmonics. Detectable signal modulation limits for SN 1987A are derived as a function of frequency in the range 10-2000 Hz.
