Hi Ben,
As I understand it, the UHD Source and Sink blocks must be in the same
flowgraph. Otherwise, after you start one flowgraph, the other will say
it can't find the device, or some similar error.
For how I solved the problem, see

Feel free to ask questions.
Good luck,

This might be more of a GNURadio question, but is it possible to share a
single USRP device (E310 in this case) with two flowgraphs? What I mean is
the E310 has a "A" and "B" channel, could you use channel "A" with one
flowgraph and "B" with another or does everything have to be implemented in
a single flowgraph with the UHD sink/source configured to have two
channels? I'm guessing the latter due to how UHD interacts with the
hardware.
Thanks!
