Hey TK, that was exactly what I was after, a BW increase... it's over 350 Euro and is actually presented as a SW package, hence the idea that it was some unlock sw key. But, if it's only a resistor swap - well, wow! do you happen to have the details? I have not found it in the forum, however I'm looking for the DSOX1202/4G, so maybe it's under some other name.
Thank you! It's really appreciated.
