Hi Jason, No, I am just using UHD driver. The processing to perform FFT and so on has been developed by myself. But I am quite sure that the processing is ok because with other receivers works fine and it provides correct results according to the test signals.
Moreover now seams that the span between the 2 spikes it's not constant (I made some test with 2 MHz span instead of 1 MHz). I suspect that should be some spurious due to the local oscillator onboard WBX ??
