Hi. I also have a problem with a low TX signal as per the closed topic: viewtopic.php?t=56747
I have about twenty such boards for possible repair (unfortunately no more warranty).
Literally nothing helps, so I recognize that the problem is hardware.
Is it possible to repair these boards? What could be the cause of the malfunction? Replacement of the processor?
I would like to repair them, because they used to work very well.
