Hi Pierre, many thanks for the suggestion, I'll try that - not sure how I ended up using that as my UHD install was done via pybombs for the initial gnuradio setup of the machine. I'm afraid to make a mess of that... is there a pybombs way of installing a released UHD version you're aware of? The hardware setup is as follows: Macbook Pro (quad i7, 2015 model, 1TB SSD) running Ubuntu 14.04 (natively, no VM). Tried headless, with head, with VNC server only... makes no difference. TX/RX antenna is the ettus vert400 whip (not ideal for 960 MHz, but for a same room testing setup the losses shouldn't make that much of a difference). In the RX2 port is a short omni stick. Both antennas see the surrounding mobile tower signals just fine when using e.g. gqrx.
