Try using different transmit and receive frequencies. tunnel.py has
some serious issues, and among them is with how data is handled with
the UHD interface where it doesn't really handle the proper SOB and
BOB concepts that would allow you to do full duplex on the same
frequency. At this point, I'm not even sure doing FDD is going to work
properly with it.
