Juan,
If your audio reports are coming back OK, then no problem, do not change anything.? However, the most impact for voice communication is in the mid audio range: 500 to 2500 hertz.? You might have the BFO set too low such that the SSB filter is allowing some of the carrier through and then cutting off the high audio frequencies.? Here is a video on the Calibration of the v6 uBITX.?
If you were to leave the BFO setup as in the first step, you would get more carrier bleed than when centered as it is designed in the 3rd step.? The first calibration of the BFO is to ensure that you get the low-frequency beat tones when doing the frequency calibration.? After setting the calibration frequency, you then adjust the BFO to bring the filter back centered on the 300 to 3000 hertz range for the maximum punch of the audio.
