you can connect a block's output to as many inputs as you want. So take
tha last block in your chain that generates your signal and connect it
both to a uhd sink (which will make the USRP transmitt the signal) and a
file sink (which will write the same samples to a file).

Same goes for the receiver side. If you use GRC just add another
connection from a block's out port to another ones in port and the output
will be send to both blocks.
