The BasicRX has 2 analog signals coming in. You can use 1 as I and 1 as
Q, in which case you get 1 IQ signal going into the host. You can also
use them as individual real signals. In that case, each real signal
would be downconverted into an IQ signal, thus sending 2 IQ signals back
to the host machine.
