I do not believe it is possible to receive data from the TX/RX and TX
port simultaneously, I believe the are tied to the same set of ADCs.
You should use two RFX cards if you are planning on doing MIMO
reception.  Check in the examples section, I don't think there is a
specific 2 antenna receive example with the 2400's; but there is a 4rx
fm receiver that you should be able to extrapolate from.
