We present radio observations of a Type Ib supernova (SN) Master OTJ120451.50+265946.6. Our low frequency Giant Metrewave Radio Telescope (GMRT)data taken when the SN was in the optically thick phase for observedfrequencies reveal inhomogeneities in the structure of the radio emittingregion. The high frequency Karl G. Jansky Very Large Array data indicate thatthe shock is crossing through a dense shell between $\sim$ 47 to $\sim 87$days. The data $\ge 100$ days onwards are reasonably well fit with theinhomogeneous synchrotron-self absorption model. Our model predicts that theinhomogeneities should smooth out at late times. Low frequency GMRTobservations at late epochs will test this prediction. Our findings suggest theimportance of obtaining well-sampled wide band radio data in order tounderstand the intricate nature of the radio emission from young supernovae.
