I have installed GRC and UHD via PyBOMBS on Ubuntu 18.04. I am working with a Ettus x310. I cab successfully run uhd_usrp_probe launch GRC that finds the SDR correctly. I wrote a simple GRC program that creates a tone, sends it to the transmitter ad then through a loopback to the receiver for display in the Qt display as an initial functional test. When I launch GRC via
PyBOMBs run gnuradio-companion I get the attached warnings and errors output in the console. The system displays on the frequency plot only a small -100 dBm tone at 0-Hz no matter what RX and Tx gain settings I use. I assume this is LO leakage. GRC continually outputs 'Gt" error codes in the console. When I attempt to end GRC it will hang and I have to force it to close. I have attached the console output when I launch GRC Any input on what I need to modify/change to get this working properly would be greatly appreciated.
