Hi Marcus,   Thanks again!   I did now the following experiment: I connected TX to RX back-to-back with 46.43dB attenuation in between. I set TX gain and RX gain to 20dB and transmit a single CW at -3dBFS. This means my output power is Pout=11.44dBm (cross checked with spectrum analyzer) and o

Just wanted to say thanks for the assistance, that worked great. As a heads up if you are building against zeus & dunfell and need fft support you are likely going to hit the same issue I did. As a work around I just pulled gcc 8.3 back in zeus. https://github.com/FFTW/fftw3/issues/213 On Fri, D

Issue appears to be with the compiler that is included in Zeus (gcc 9.x vs 8.x) and an interaction with fftw. There is an open issue with fftw ( https://github.com/FFTW/fftw3/issues/213) and a request to the yocto folks to request they consider adding back gcc-8.3 to zeus + dunfell ( https://bugzi
