Substituting the Raduino to eliminate the problem suggests this was another case of oscillators beating together in mixers to give rise to annoying audio tones.

Really the problem was it is in vfo CLK # 2
I inserted the rf generator at approximately 52Mhz and now we have the normal operation of ubitx.
Probably some defect in SI5351.
Lucky I have another raduino board.
I leave here my contribution to who in the future find this same defect, and that apparently would be the TDA2822 and was not.
