See how the dual usrp wrapper in grc does it:

Hi Matt,
Is there any example in current Gnuradio release that implementing full deplex
with one USRP motherboard and two daughterboards?
As i understand, i must call source_c twice to use the two daughterboards, but
this seems impossible. Then how can i use the two daughterboards in one
flowgraph?
Thanks very much!

Hi everyone,
is it feasible to transmit and receive simultaneously having one USRP1 with
2 daughtercards (2 RFX) (for example in Side A receiving and in Side B
transmitting)? Is there any example in GnuRadio?
Thank you in advance
Yes, this is known as full duplex. You can even do it with a single RFX
card both transmitting and receiving, but it will have somewhat higher
crosstalk than with 2 daughterboards.
