Simultaneous observations of impulsive hard x-rays and type III radio bursts associated with two recent solar flares have been analyzed in order to study the characteristic increase in the starting frequency of fast-drift type III bursts during the impulsive phase. The time variation of the starting frequency has been found to be similar to that of the 35 KeV x-rays, especially during the increasing phase. A similar variation has been observed for the low frequency cut-off of these bursts. The observations are consistent with a systematic downward shift of the electron acceleration/injection region during the impulsive phase of solar flares.
