Hi Jerry,
I've thinked a lot about your post and here is a diagram of the setup I want to make on my rig :
This setup gives me the possibility to choose on S2 weither to use an external PSU or not for PA PWR (if I'm a my QRA I'll have a PSU available, when on a hill only the battery).
I all cases, the battery is legacy to supply the uBitx and the uBitx is powered on by S1. Maybe it could be a good idea to have a 2 separate ways S1 to cut off both battery and PSU line).
Also, the D1 is in serie as proposed.
What do you think ?
