Hello again Evan-
Alleluia ! It is working ! There were some bad solder joints in the vicinity of Q10, Q11, and Q12. After soldering them again I noticed right away that the set was working: a real increase in noise when connecting the antenna. And now for the alignment of the power transistors, and further finetuning the master and the BFO.
I can only agree with Allen: a big THANK YOU for the help. Thank you, thank you, thank you very much !
By the way: I do have a Kenwood TS120V and an Icom IC7300. But I enjoyed very much building the uBITx. I already have a 3.5 Nextion display installed, the next step is building an S-meter.
