[Discuss-gnuradio] Multiple Channel USRP Confusion

Hi all,

I am looking to simultaneously record two real signals (not with IQ) using a single LFRX daughtercard.

How can I do this with GNURadio companion?  I have spent a while looking at the USRP Source and Dual USRP Source blocks and could not figure out.

I am looking to record from Side A with RXA and RXB.  I tried setting the RX Antenna setting to RXAB and used the complex to real block to extract channel RXA, and complex to imaginary block to extract RXB.  I don't think this worked properly.

I also tried using two separate USRP source blocks, each on side A but one for RXA and the other for RXB.  When I did this I got an error related to already having one USRP side A block running.

Any help would be greatly appreciated
