I have completed the build without any major issue. First power up looked OK, no smoke. Out power on all band appears within range and RBN has picked me up OK. I have an very annoying background noise on receiving, it sound about the same on all bands, in a 550 to 900 Hz range, S4 minimum. The noise is there, with and without antenna or dummy load. I checked it outside, away from any man-made noise...I did? a recording as an example. Other radios close by do not exbibit the noise. Any idea?

Hello Jean-Jaques,

please send screen shots from Terminal - Diagnostics - RF filter sweep and - Test ADC I/Q for a lower and a higher band.
