Capture

Run ./gold_capture_1h.sh with your Ettus USRP attached. You MAY need to do some tweaks, such as turning off IRQs for the core you are running this on to ensure that you get good quality data. An overrun will put a gap into your data's I/Q file output and makes the whole sample worthless. Read along to see how I got around that.
