Thank you Jerry,
For now I've just reworked the drawings, based on the old one. It's better quality and very good to print.
I've some questions on my side too :
What is really the difference beetween PA PWR and +12V ?
Isn't it more simple to enpower just by the Alternate power? with a switch, connected both on PA PWR and +12V all the time, even though you power the ubitx with battery or with DC supply ?
