I am using the RFNoC radio_ctrl API with my X310 and when I call get_rx_antenna() , I get an empty string. The problem is in x300_radio_ctrl_impl.cpp. The corresponding set_rx_antenna() function should be calling the base class radio_ctrl_impl->set_rx_antenna() so that the locally cached value is updated. But, this call is missing. Thus, any call to get_rx_antenna() which is not overridden for the X310 always returns an empty string. Rob
