Hi, I'm so sorry. This is the original email message.
I am actually trying to do a half duplex (receive) using one board (900MHz) and
half duplex (transmit) using another board (1800MHz) in the same usrp. I have
another usrp for the same function. I actually make use of the benchmark_rx
and b
r to go back to the transmitter mode after doing so.
