I will take a look at the attachment.Â That is great, I want to
eventually sample 4 real channels, and want to avoid the
Thanks for your help!!

I have a solution that I have been using for a while. I have attached
the relevant files and a working example. You will need to put all the
files except the .grc file into your .grc_gnuradio directory and restart
grc. Not sure if this is a good way to do it, but it works for me.
the helper blocks are the core, the dual_a, dual_b are heir blocks that
add on top of this one. I also included a quad source block for real
inputs using 2 LFRX in case you are interested. I have changed the fusb
parameters such that I can records data at high sampling rates (4MSps)
without getting overruns.
Hope that helps.

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?Â 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.Â 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.Â 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.Â When I did this I got an error
related to already having one USRP side A block running.
Any help would be greatly appreciated
