I guess I should have debugged a bit longer before posting. The problem has been solved. Once I entered in "[0,1]" into the Stream Channels text box in the USRP Source element in my GRC flow graph, both channels began receiving. Thanks.

I have an X310 with two UBX-160 v2 daughter cards installed. I've built a single channel GRC flow graph, using Subdev Spec of "A:0" then "B:0", to confirm that each of the daughter cards receives correctly. However, when I increase the Num Channels from 1 to 2 in GRC, and use a Subdev Spec of "A:0 B:0", I get this error:RuntimeError: LookupError: IndexError: multi_usrp: RX channel 139784932838560 out of range for configured RX frontendsI am using GNURadio version: 3.8tech-preview-215-g7e5396b2I am using UHD version: UHD_3.14.0.0-0-gd20a7ae2I'm attempting to build a dual-channel satellite surrogate system.
