That is a more verbose way to say that "you cant receive from TX/RX when you are transmitting". It just so happens that the antenna switch gets moved to RX2.

To use the board in full duplex mode (simultaneous receive and transmit), set the receive antenna to RX2. -Josh _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
