Abstract:
Three V.H.F receivers of high gain stability and low internal noise designed and constructed at the Kodaikanal Observatory are described. The receivers which operate at 1 1/2, 3 and 5 meter wavelengths are being used for the measurement of extra-terrestrial emission of solar and galactic origin and also for observations of radio-star scintillation. A report on the performance of one of the receivers over long periods together with details of aerial systems used and calibrating equipment is also given
