Can I add that somewhere in the python code? Along with : self.usrp_simple_source_x_0 = grc_usrp.simple_source_c(which=0, side="A", rx_ant="RXA") self.usrp_simple_source_x_0.set_decim_rate(250) self.usrp_simple_source_x_0.set_frequency(0, verbose=True) self.usrp_simple_source_x_0.set_gain(0) Greets, Jasper

DC offset correction results in a narrow spectral hole around DC.
