There seems to be a colossal amount of activity trying to get the original nano and its derivatives to have improved performance at the top end by endlessly tinkering with the firmware versions and settings. It is all above my, and I suspect most others’s heads and I would not have the time for it all anyway.

Why not just get a nano v2 which works well up to 3gkz and up to 3.5 ghz with some loss of performance. And it costs little, if any more than the basic nano.

There are far more ordinary nanos about than v2. Why? I have two versions of both (when the 4” screen n connector v2 arrives) but cannot use them much yet as I am rarely at home at present.

I am also waiting for my Tinysa to arrive, so I can throw out three HP141 boatanchors, a boatanchor signal generator (the Tinysa seems to be an acceptable replacement) and several liftable other spectrum analysers. Anyone want them? (Northwest England).

Hi,

Up to 1.5GHz, some prefere nanovna-H4 because of the bigger screen (till now) and because of the ease of operation in the field, and speed/performance.

With V2 once you change the initial frequency range, you need to manually reload the calibration, for example.

Then the nanovna-Saver software took some time to be V2 compatible.

There is also a bigger developement and testing using Hugens nanovna-H4 from the nanovna community.

I guess it only depends on your needs.

It seems that over on the nanovna group, several valuable contributors have just thrown their teddy bears out of the pram.

I must admit it was getting very technical and some others were making what was becoming “demands”, as if the firmware and pc-end saver were commercial products with a warranty, rather than free time/ hobby involvement.

I was looking forward for the stable end result, which may never happen now. I will stick with my V2 which seems to have more universal capability with the only disadvantage is calibration retention. My basic nanovna is on (possibly permanent) loan to a friend.

Hi Stephen,

Thanks for the input.

I reckon all the hardware flavours have stable releases, simply use the manufacturer firmware versions ;) as you are doing with your V2.

Some of the developers will continue to do their magic in a more close/controlled forum, and once the desired stability is reached for the new features, it will be shared with everyone.

Both firmware and PC software are constantly being improved and bug corrected. Don't you just love how fast things happen now? Its up to you what branch you want to follow... the stable or the volatile HI

All the best,

Luis, CT2FZI

There's a lot of that going around in many of the groups. I'd say it was
the pandemic or Trump or Brexit or mass unemployment or solar minimum, or
maybe all those combined, but this kind of thing has been going on for
years--decades--now. It's the mentality and behavior of H.R.H. Consumer.
You can give him or her something free of charge, and he or she sometimes
still complains and makes demands. If they actually pay some amount--any
amount--they can behave like the Prince of Darkness himself. Makers, i.e.,
producers, are much nicer people, generally, perhaps because they have the
self-assurance of knowing how to do things and why they're doing them.
Consumers have no such solid ground to stand on, so the tantrum is their
only recourse.

Maybe a vaccine, the November election, or a higher solar flux index will
settle H.R.H. down a little, but I'm doubtful.

Best,

It explains a lot of the behaviour and the anxiety of not having the perceived best

I've read Schwartz several times, and I have it as an audio book. It's one
of the reasons I try to never ask, "which is best"? Instead, I try to ask,
"What are my requirements?" I don't need to be "blown away," I need to be
*satisfied*. If the cheapest (or oldest, a.k.a, "obsolete") version of
something will meet my needs, I usually go with that. If I find I need
something more or better, I'll act on it at that time rather than make or
buy for some possible benefit in the future. And I'd rather buy something
and be disappointed with it than *not* buy something out of fear of being
disappointed. The thing I bought--a tool, maybe--can still be used, even
though sub-optimal. That means I was *doing something* with it rather than
*doing nothing* except wringing my hands in confusion and endlessly surfing
the web for reviews, etc., out of fear of making a mistake. In fact, why
would I allow _fear_ to slither into activities I pursue for pleasure and
personal growth? Don't we have enough real existential threats to fear in
life without being afraid of buying the "wrong" version of the nanoVNA? ¡*Madre
de dios*!

I think there are people who try to buy the "best" or the "top of the line"
out of pride--they think they deserve the "best" and that they can take
pride in owning the best. If I ever find myself feeling that way, I hope my
family and friends will intervene. I want to take pride in _doing_, not
pride in _owning_. I want to be a _maker_, not a _consumer_.
