Hello Gerrit U
First: think that every Ubitx 5.0 has different calibration. They are all a little different!
But it will help if you know the values from other Ubitx 5.0.
When i was starting with the Ubitx 5.0 it was almost impossible to calibrate it..at that time; until
I got the values from another Ham.
Now i am the owner of two Ubitx V5.0 and I will give you the values from both of them.
Both i modified them withs a Nextion 3.2 and a Nextion 5 “display.
One of thisUbitx V5 i calibrated with the original display and software. So you don’t need other display and software.
So give it a try.
It will be much easier if you install KD8CEC user interface; so you can use UBITX manager.
Hope you can use i and find a good solution.
