I just found and applied this
and for me checking in uBITx MM software the IF function and then setting ATT=70 made a big difference in receive performance.
The number of FT8 signals received just exploded, at least doubled or tripled.
At the moment I am receiving WSPR and the system with the uBITx is better then my YAESU FT450D.
Of course they are on different antenna's
All this was after noting that my base frequency was allright, about 8 Hz different from FT450D (2ppm) on 80 meter.
And correcting the 'location' of my USB sideband, as this was too far away from the dial frequency.
I calibrated the BFO by carefully changing the big number in MM for USB calibration. In my case factory setting 11054600 and now 11056500. This took me 7 iterations watching the change in the 2 FT8 results: dial frequency and active bandwidth.
This started at 7.072.000 between 2300 and 4500 and ended where it should be at 7.074.000 between 300-2600.
Both VFO and BFO can still be improved I know.
Oh, I am currently using the latest CEC firmware 1.20
