Ok, so if I get this right you want to transmit and receive in burst-fasion, 2xRX and 1xTX. Could you provide some parameters such as sampling rate for 2xRX, sampling rate for 1xTX, burst length, silence period between bursts? I was doing such thing in SoapySDR for 2RX & 2xTX some time ago and it worked quite well (assuming sampling rate for both TX and RX <=25 MHz).
