Starting in 2004 we have carried out a series of sensitive searches for radio emission from extrasolar planets at the Giant Meterewave Radio Telescope (GMRT) in Pune, India. At the operating RF of 150 MHz, we have determined that the GMRT has a sensitivity of a few mJy with an integration time of one hour. Over the last two observation cycles, we have collected simultaneous interferometry and phased array mode data. We have used the interferometry mode data to produce radio maps and have obtained dynamic spectra in the phased array mode. In this talk, we will present our results from the 2004 data, which included targets such as Tauboo, 70 Vir, HD162020,and HD179949. We will discuss our RFI removal strategy and how it has allowed us to improve our sensitivity, despite the loss of some data. We will also present a first look at recently collected 2005 data, which included targets such as the HD1833 system (recently discovered planet in a triple star system), UpsAnd (system with three planets, including a ``Hot Jupiter"), and Gj876 (nearest ``Hot Jupiter" system detected so far).
