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.
