Hello. I'm trying to build a two-way TDD system with two USRP1 boxes in pure C++ using libusrp and inband_2rxhb_2tx.rbf firmware.
Now I have working system where one USRP1 box transmits data and other box receives.
I try to make the second box transmit data after it received certain frames. The issue is that when I try to enable transmitter on the second box the receive signal level significantly decreases. Typically received samples are in range [-15000; 15000], after enabling transmitter they are in range [-1000; 1000].
