Jerry,
Did you have a look at the User Guide I edited, located in the files area?
I used feedback from several members to make sure the user interface info was fairly clear.?

That's good to know.
I am curious if you can remember what "newbie start here" document got you going with the nanoVNA.

Finding technical information of any sort is much easier with the web than when we were young.
When I was 10, I was digging into every encyclopedia I could find to figure out how a radio worked,
but never found anything that did more than name a bunch of elements (microphone, oscillator, etc).
I eventually bought an ARRL Handbook (a major expense!) which helped considerably,
but the handbook of the time did not have much to say about complex impedances.
I had no idea how to gain access to anything better.

Digging about in the wiki or the web at large for information on VNA's is pot luck at best.
Most of it would be incomprehensible to somebody starting out.
And terribly discouraging.
Telling somebody in that situation to just poke around out there
and follow the rabbit holes is not good advice, IMHO.
Way too many rabbits.

As stated before, I'm a retired EE with a career in digital design.
By no means an RF engineer, but I have a fair grip on the fundamentals.
The couple of nanoVNA guides I saw mentioned as of mid 2019 did not
adequately describe how to use the standalone menus of the nanoVNA.
I did eventually find that FlexAndHex tutorial, which I can recommend.
There might be better out there.

At the start of this thread, I asked what the preferred firmware for a
classic nanoVNA might be.? The answer is not obvious.
The firmware repositories may not state what hardware they are intended for.
There is no document that compares the various possible firmware repositories.
A bunch of information popped up in the responses that really should be in the wiki.

That was my experience, perhaps my tolerance for poorly documented
user interfaces is lower than yours.
My preferred user interface is a unix shell prompt, most 10 year olds today
would have a much easier time than I with my android phone.

Or perhaps you stumbled upon a decent tutorial more quickly than I.
