I am using RFX2400 daughter boards, VERT2450 antenna which I received with my USRP from ettus, I have tried different bitrates from 40kbps - 100kbps but got same results, I am not observing any overrun or underrun, I am working in office environment where I dont have any interference (almost), Gain = 0, but I have tried other values [0-20].
