Dear mailing list,
I have a small question: Im using an USRP-2 with a WBX daughterboard (Gnuradio 3.5.0), and I want to use the RX2 port as the receiver and the TX/RX port as the transmitter. In the GNU Radio companion flowgraph, I enter RX2 in the antenna-field for the receiver UHD::USRP source block and TX/RX in the antenna-field for the transmitter UHD::USRP sink block. When transmitting, I deliberately provoke underflows at the transmitter side (I transmit packets, and stop transmitting in between). When connecting a scope at the receiver end, I seem to observe that during these underflow periods, the receiver still switches back to the TX/RX port. When transmitting, it switches to the RX2 port. This is despite the fact that I specify that the receiver has to use the RX2 port, which it should use all the time. Any advice on this?
