Hi Erik
Thanks for your swift reply.
I was aware of the wiki but haven't found reference to how you ascertain if a particular nanoVNA is (or isn't) upgradeable to higher frequency operation. (1.5GHz)
Also, I can't find a menu option to display what version of the software my nanoVNA is running. Unless the momentary 'splash' screen Gen11 is a clue?
Other contributors seem to have a CONFIG option in their menus.
