Hi, I’ve attached the GRC file. I am using USRP B210, I connected the RF cable from tx to a 30 dB attenuator back to the rx and then another RF cable from another tx to the Spectrum Analyzer. I am using GNU Radio Companion 3.7.9 .
Thank you in advanced!

Providing a GRC file would be helpful. What kind of USRP are you using? What physical connections do you have on the device? What version of GNU Radio are you using? From a high level, you should be able to TX and RX simultaneously without error.

However, now I would like to receive and transmit the same signal out. I tried connecting USRP Source block to USRP Sink, and I see lots of “LLLLLL” which is late packets. Anyone has any idea on how to do a receive and transmit the same signal out in real time using GNU Radio Companion?
