Andrea,
The section at the end of the Memory Manager pages is if you develop and add a custom low pass filter for the transmitter.? Since you have not made any hardware changes, you should NOT check the custom box; the programmed defaults will be used.
I understand you see greater than 10 watts on 20 meters on both CW and SSB.? I do not know how that is possible unless you have RF feedback while transmitting, which is getting back into the transmitter.??
If you return to the original code downloaded from here, does the problem disappear?
This is the "stock" code that is loaded into the uBitx.? You must return the original screen, as Ashhar Farhan's code does not work with the Nextion display.
It might be helpful to read the values from your uBitx, save them to a file, and then post the result here.? We can check it for any indication of EEPROM corruption.
