I am running the ATSC Transmitter flowgraph that is included with some GNURadio compilations. I am connecting the output to a HackRF, using the Soapy HackRF Sink and monitoring the results on my spectrum analyzer. I also have the QT GUI Frequency Sink connected. When I run using either sink alone I get a nice ATSC signal either displayed or on my spectrum analyzer. However, if I enable both sinks at the same time the waveform changes in the display and what the HackRF puts out is radically different. Why is this? Is there a way to have the display as a monitor and get an undistorted output from the HackRF?
