Dear Guys, I encounter one strange problem, I can use usrp to
receive signal but cannot transmit signal. My usrp is USRP2 and gnuradio
version 3.2.2. When running ursp2_siggen.py, it do not return any
error but when I use a spectrum analysis, it shows no signal is
transmitted. When running benchmark_tx.py and bbn80211_tx.py, it
also reports no error, but there is no signal sent out. Do you
guys have any advice? Thank you.

Note, when I runursp2_fft.pybbn80211_rx.py
They work well. So I know the RX part is OK

Which port is your antenna connected to? In SBX/WBX daughterboards, you
can
only transmit through Tx/Rx. However, you can receive through both Tx/Rx
and Rx2.

This might not be related to your problem. But just checking.

Thanks,

Nazmul
