Yes, I did miss that reply! *Very sorry about that.* Let me try to
answer your questions:
First, I did try to use a single Source block with two channels on the
advice of a colleague. I've been unable to get that to work either.
(More on that below, after I answer your questions.)
The x310 has WBX (A) and UBX (B) daughtercards.
The x310's UBX RX2 input is coming from the TX/RX output of an N210
with a WBX daughtercard. The N210 is generating a DSSS signal and
transmitting it on TX/RX.
The x310's WBX RX2 input is coming from a passive antenna (Ettus
WA5JVB Log Periodic 850 MHz to 6500 MHz).
The x310's UBX TX/RX transmits the sum of the UBX RX2 and WBX RX2 signals.
A third SDR (x300) receives the x310's UBX TX/RX signal and that is
the USRP I fetch data from using uhd_rx_cfile.

You need to specify a subdev spec of:
A:0 B:0
Right now, you just have B:0, so it's trying to produce two channels
from a single sub-device ,and, obviously, failing.
