Hello Larry,
Firstly I do thank you very much for taking the trouble to reply.
The answer to your first question is that I find nothing in the files area that is later than the versions that I have tried to use. (Except a version for 75 ohm operation that don't need.)
The second answer is that in my user guide (19/11/19) I see no reference to Clear config, and (as yet) I have not found it in the files area either. So no, I have not been using that command. But I have just downloaded a load of stuff to read, so I might find it in there somewhere.
I can go on using the limited version if I must, because I do have an AIM 4170 for anything below 180MHz, and two PHSNAs (one with the sweep mods) which tend to get put on first because they are so easy to use. So I only switch the NanoVNA on for higher frequency use. (So you didn't need to know that, but you might have found it interesting. If it bored you then I apologise.)
I will come back if I find sucess, in case it helps anyone else.
Thanks again Larry. I do appreciate it.
Tony...
