Ok. But I Dont see it in all Rx channels. Do you think it’s related to isolation issue between tx to rx

Hi Rick,Sorry for the mess in the terminology...I think i had a mistake that take 10*log10(peak magnitude) instead of 20*log10(peak magnitude)Thanks for clarifying...

Thanks kazI'm talking about amplitude only. The gain is 6 dB of amplitude, the FFT peak is amplitude peak 10*log10(abs(peak)), and the RMS I measured is amplitude...
