Abstract : The Giant Metrewave Radio Telescope (GMRT) is nearing its upgrade. With this upgrade of GMRT, this instrument remains as the most sensitive interferometer in the world at low radio frequencies. Briefly, among several aspects of the ongoing upgrades, key features are a brand new frond-end and digital back-end, RF receivers, etc. These upgrades provide us with nearly a seamless frequency coverage from 120 MHz to 1450 MHz with bandwidths as large as 400 MHz over 16k spectral channel resolution. Here, we present the status of two new recently deployed bands, Band-2 (120-240 MHz) and Band-4 (550-900 MHz). In particular, we would compare the improvements in the quality of upgraded GMRT data and data from the legacy GMRT system.
