[Discuss-gnuradio] two channel configuration in GRC

Hi all,

I'd like to have two simultaneously receiving channels in USRP1 with two WBX daughterboards.

When I put one "USRP Source" block in GRC and set its "Subdev Spec" as "A:0 B:0" everything is OK.

But I have no idea how to get it when there are two "USRP Source" blocks in GRC!?

Setting "A:0" for one USRP Source and "B:0" for the other does NOT work!

Thanks in advance!

regards,

Ali
