I have an original NanoVNA: it only goes up to 250 MHz. Can I upgrade the firmware and obtain additional functionality? If the firmware can be upgraded which version should I load. Tks.

it should go to 900 (3rd harmonic) or 1.5 g (fith overtone)

You're correct. I was thinking about it and tried it: the NanoVNA does go to 900 MHZ. And all this time I thought that since the default stop freq that it 'boots up with' is 250 Mhz that it was not capable of going higher. That will teach me to test before opening my mouth.
This makes me feel better: less worried 'bout changing firmware.

Of course you should still upgrade to the latest. You will get bug fixes, performance improvements, and new features.

As a 25yr veteran in sustaining engineering, the ¡°should I upgrade?¡± question always makes me laugh uncontrollably. If you don¡¯t know why you shouldn¡¯t upgrade, the answer is always, ¡°¡upgrade¡±.

Right. The question should be "am I missing something I want to use right now or am I using something that has a bug and should be repaired right now." If you don't know what you're missing and all your tests are performed well, why should you upgrade. Yeah some bugs might be solved, but others could enter just your tests. This is like a married man who wants an upgrade of his wife, is it necessary, is it broken?

"Can I upgrade the firmware and obtain additional functionality?"
Yes. You didn't say how old your NanoVNA is, or its firmware version - but, if you carefully make note of its current version, find, download and save that version, then you can install any newer version. Test any new ones, then, and you can still go back and re-install your current version.
If your current one is more than a year old, there will be many new features in newer versions.
You can 'swap around' firmware versions sort of like you can swap pairs of socks. Well, it will be harder the first time.
There's an old "AA" version that's nice for use testing antennas outdoors - it has an extra-large text font for much easier readability in brighter light. The "AA" seems to be for "Antenna Analyzer".
Be sure to read up about changing firmware, and maybe also watch some videos about doing it. The first time or two will seem a little tricky or difficult, but that's mostly just because it's something new (to you).
Good luck, and have even more fun with your Nano!

I have a NanoVNA H4. One thing I like about recent firmware updates is that, when you save a calibrated frequency range in the memory, it then actually displays the frequency range that is stored. Older versions didn't do that. Zack W9SZ On Tue, Jul 12, 2022 at 12:15 AM Jim Shorney <jimNU0C@...> wrote:

All the large engineering projects I have worked on have had a "tool freeze" date. Once the software tools for the project have been chosen we update to the latest known good version, and then keep that version for the duration of the project. That way everyone has the same tool versions; all the tool bugs become quickly known, along with their workarounds; and no new bugs appear late in the program.

Somehow you all missed my point a few days ago¡.. much of the upgrades in firmware are beyond the pay grade of many of the initial users. Until one gets used to using the nano (or your handheld or any new radio tool you have) and performing the tasks it was originally designed for WHY have new features that one doesn¡¯t need or understand? The learning curve of upgrading (especially if you have never done it before) can be intimidating and an error makes your nano useless. It¡¯s always nice to have the latest greatest whatever but much of the time it isn¡¯t needed. My initial H4 nano from R&L Electronics still does all I have needed it for. Someday when I get snowed in or whatever I might look into upgrading but if I don¡¯t need the new features why bother?
There are those who need to have the latest greatest and for them that is fine but many of the upgrades are for special needs that don¡¯t apply to all of us. Maybe if I had a local guru walk me through upgrades a few times I might change my mind but doing an upgrade just to do it doesn¡¯t make sense. If it isn¡¯t broken why fix it? I originally had a guru help me set up my DMR handheld and hotspot and then he moved away¡.. it still does what I need even though there have been upgrades to the AnyTone 878. I am still having fun and haven¡¯t needed to write an email here because I screwed up and bricked my handheld or nano. The newest young guru in our club goes through it all so fast I can¡¯t keep up. He¡¯s not a good teacher even though willing to do upgrades on some things¡. But not the nano yet, just DMR.
Case in point¡. Windows upgrades! How many issues occur every time that happens? It sure generates a multitude of emails to the various QRP groups I follow. Even Linux seems to have multiple upgrades of each version¡. What to do?

David,
I agree with you: my NanoVNA with original firmware does exactly what I want I to do. Sure there may be useful new features in the updates, but one thing that really puts me off is that a major feature of this forum is people having issues with updates. It might be worth doing an update simply to see what is involved and learning from the process - but I don't need to.
Windows upgrades: after every upgrade I have to go round my networked computers and reset the network settings or they won't talk to each other!

sometimes you get a device that has a very old fw in it (seller had it for a year before selling) ... with maybe slow scan speed and lower points per scan (and that means lower resolution!)... and even on dealers hp you do not find the newest
maybe fw is changed somewhat that it works with this or that windoze soft
or new functions added that may be helpful ... or ...
so ... i would ask what is newest "stable" version for my unit and then upgrade

I have not found any upgrade for the NanoVNA that required any "learning curve" besides what was needed initially to learn the instrument. Operation has been as it always was. Some of the improvements included more samples per frequency segment you wished to look at, and adding a display of the frequencies to the memories. This was a great addition to me, as before I always forgot what frequency ranges I had put in each memory and had to go through each one to find out. There have been other "transparent" improvements in the upgrades which I didn't even notice, but helped out.

Apples and oranges. The Nano is a small dedicated purpose device with a tight team of very smart developers. Windows is a bloated Swiss Army knife *operating system* software by committee. Hardly a fair comparison.

One basic practice of networking is: "If it works, leave it!". If your VNA
works well-enough for you, there's no /need/ to upgrade, but also no reason why
you should not experiment - if you wish.
I try to wait a few weeks after an update is released before upgrading, see how

I also upgrade.. In some cases just minutes after an upgrade is available (example sdrradio console)... But that's off topic grin
I am also a member of test team group..
So if you are not fear of upgrading and maybe step backwards if there is a bug (or just wait for next release) then i try to be right on the last version.. Be it with sdrc.. Or with v2plus4 or v2
That helps developers to find bugs easier
Imagine you find a bug.. And tell programmer that it is "somewhere in the last 20 versions"... Not easy to find
If you have only one device.. And need it regularly.. Then maybe stay a bit slower on upgrades... But i have three different v2 units.. So i test a new fw in one.. And if ok i upgrade the other two
Cause those are a bit different. Its a good test... I have a v2 modded with a 4 inch screen... An saa2n modded to v2plus (means 4 inch and n socket)
And a v2plus4 (4 inch but much different fw cause bootloader used is closed source)
So three slightly different units.
If i have some sparetime i will add sd card to one... And use fw from dislord that supports storage on card..
So.. The v2 and all of its clones, brothers and daughters... Is a living project
Where one can stay on a unit and fw and just use like it is.. Or upgrade and modify (sometimes with solder work)... And have all newest bings and boings
(sd card storage, real time clock, battery display)
So its your choice to have an up to date unit.. Or stay in an earlier fw

After 35 years in IT, I¡¯ve learned a few things about software/firmware upgrades. The decision to update *anything *depends on 3 factors: business need, supportability, and risk. This is true of your NanoVNA, your PC, your radio, or whatever... Only YOU can determine if YOUR 'business need' requires an update- examples would be desired functionality or usability enhancements, or fixes to bugs that affect your use of the system. 'Supportability' factors include whether support from the provider is needed or desired, and what their policies are. Don't expect much help on a very old version of software that's had a lot of development since that version was released. If you ask a software provider for help, they will likely (and rightly) ask you to update to the latest before trying to troubleshoot your issue. They're not being difficult - they just don't want to spend time on something that may already be addressed in a newer version. 'Risk' is the factor that's often overlooked or misunderstood. There are many kinds of risks. For a standalone device with embedded firmware, the security risk is pretty low, but there can still be operational risk (not fit for purpose, etc). That's where 'if it ain't broke...' makes sense. For a device that's going to talk to a hostile network (which these days means most any network), the risk of vulnerabilities in old software increases exponentially. In that case, updates are important whether business need or supportability suggest a need for an update or not. In ham radio, some of the latest transceivers with ethernet connectivity come to mind. I would want some assurance that the manufacturers are keeping up with security patches, and apply those in a timely manner. Don't forget to include the risk to others in your risk assessment - unpatched devices on the internet are routinely used by the bad guys to attack or defraud others. Don't be that guy. In summary, the question of when or whether to update any software or firmware is neither 'apply every update' nor 'never update' - it has to consider business need, supportability, and risk. You probably do that without explicitly thinking in those terms anyhow, but deliberately thinking through it will either confirm or challenge your instinctive decision. 73 de W0ZF On Wed, Jul 13, 2022 at 4:20 AM David Wilcox K8WPE via groups.io <Djwilcox01@...> wrote: Somehow you all missed my point a few days ago¡.. much of the upgrades in
