Finally the reason of this is explained by Tom N0SS. It's regarding
that the TUNE function do not use the ALC. This why we have sometime
different value when hitting the TUNE button.

After a complete recalibration of my K2 this morning, and also after
checking all ouput band at 5W and 10W, I can now say that everything is
working great !!!
