An analysis of the gradual enhancements which repeatedly appeared 20-50 min after the onset of an impulsive burst on 6 November 1980 is presented using microwave and hard X-ray data. It is found that the gradual enhancements exhibited time profiles which were similar in both the frequency range of 17 GHz to 160 MHz and the energy range of 40 to approximately 400 keV. The low peak frequency of the microwave spectrum (approximately 4 GHz) and the flat X-ray spectrum with the power-law exponent of approximately 1.7 are also found to be characteristics of the gradual enhancements. It is proposed that the radio and X-ray enhancements are a result of a single population of energetic electrons which extends high in the corona (at least 140,000 km). However, it is suggested that the 17 GHz source is at a low altitude, not much higher than the preceding impulsive burst source.
