You can use FFT sink block to see your signal.Just connect after your
USRP
source block where you can see your received signal.

i didn’t mention any port numbers in my grc file.U can still set up sink
and
source blocks on the same grc file.since the usrp knows that sink is to
transmit and source block is to receive.

all you need to do is connect them and run the grc files.
