I am having trouble understanding the difference between radio select
and channels on the X310.
It appears that the X310 has a radio select A [FPGA block Radio_0] and
B [FPGA block Radio_1], but both of these only have one channel?
Whenever I try to use a channel 0 and channel 1 for Radio_0 I get the
following error:
What daughtercards do you have one your X310? Many cards have only a
single RF channel.

Is there a way to enable a channel 0 and 1 for Radio_0? If not, is
this because of hardware limitations or because of software limitations?
