Is this not true?

def set_fc(self, fc): self.fc = fc self.blocks_message_strobe_0.set_msg(uhd.tune_request(self.fc,0)) self.uhd_usrp_source_0.set_center_freq(uhd.tune_request(self.fc,0), 0) self.uhd_usrp_source_0.set_center_freq(uhd.tune_request(self.fc,0), 1) self.uhd_usrp_source_0.set_center_freq(uhd.tune_request(self.fc,0), 2)
