Re: [Discuss-gnuradio] GRC problem

Your transmit amplitude is almost zero, try something around 10e3.

See the notes in the usrp source block.

But I can not see anything in the last scope_sink. The correlative parameters which I set about the usrp_sink and usrp_source are the same as the defulat value in the benchmark_tx.py and benchmark_rx.py.and the other parameter in the other block is the defult value.Can anyone tell me how to figure out this problem?
