The important thing to know is that all MB1s that I have seen, including mine, show the PA Voltage as 11.5V. Whether 0.4V down is really an issue seems to me to be something to ask Roman directly. I suspect that there is no problem at all and I'm sure he will confirm that if you ask him.
I am wondering if the program reads all the parameters using the TCI protocol or it works with the native EESDR protocol.
Anyway it is a great improvement.
Thank you very much for demonstration.
