Thanks again,
?
I resoldered all eight points and now I get proper SWR readings! I didn't find where to measure ADV_REV and ADC_FWD but I now get good readings that match my NanoVNA (at least where the sweet spot is). So problem solved!
?
Now I got another idea - to find a way to have the esp32 that controls the motor for the magloop tuner stop excactly at the point where the QMX's SWR measurement is the lowest.
?
