Hi again, Do you think I should revert my UHD to an earlier version? If so, which version do you recommend? Or is it a better idea to make the correct changes in the Transceiver52M? In that case, where should these changes be done? Is it in USRPDevice::open(...), USRPDevice::start(...), or is there another place more suited for this? Sorry for all the questions but I'm a novice at UHD and OpenBTS.
