Hello,
I¡¯ve read a lot about the isolation of analog and digital masses
and their star connection.
For me and for the digital masses, I see at least 4.
The arduino, the SI535, the Nextion and the encoder.
Knowing that my Arduino and my SI5351 are on individual tulip support for each leg, it¡¯s easy to isolate them (desolder the tulip for each leg) and connect them alone together and after to the ground.
What do you think about it. Is it the design of the Ubitx with the card in front?
If you have any other ideas., tell me.
