Ujala You have to use usrp.tune(self.u, 0, self.subdev,106.2e6). This will mix whatever is at 106.2MHz down to DC. set_rx_freq is used to control the DDC in the USRP and only works from -32e6 to 32e6MHz.
The tune function first uses the mixer in the TVRX db to mix the signal down to 5.75MHz (the TVRX db that I'm using mixes the signal down to 44MHz). If you're using your db, the signal gets sampled and sits at 5.75MHz. The DDC now needs to mix it down to DC. The tune function takes care of both of these functions for you. Try to capture a signal by setting decimation to 250 and tuning to 106.2MHz. The result should be a signal shaped like a bell that nearly spans the entire length of the plot.
