There shouldn't be, aside from inevitable analog cross-talk if both TX 
and RX operate on the same frequency.
Even if you manage to perfectly decouple the RX from the TX antenna, 
you'd get something like -54dB - -60dB crosstalk if RX and TX are on the 
same PCB -- that's basically the physics of PCBs.

:)

By the way, what I find pretty helpful for things like these: Use the 
ZMQ sinks in your VM to get your samples out of it, and use GNU Radio 
natively on your host machine to receive these samples, and run things 
like gr_fosphor there.
