Beware of cheap underperforming clones

As of 2023 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.

See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

Sorry for the incorrect address.

I and very disappointed to find that the firmware is now some two years old,
and doesn't incorporate many of the latest advances.

Cheers,
David

Hi, we're working on troubleshooting the remaining stability bugs in the next firmware release, we are aware it is taking a while and apologize for the inconvenience. In the mean time we are going to release a minor update to 20230711 to enable the ADF4350 output power adjustment, and to get 20230711 released for the V2 Plus4 series.
Thanks

Hello,

a major update had been promised for 10/2023.
So when will be released the major update ?
I honestly expected more communication, this will take users (and customers) calm and waiting.
Would be great to know also the status of various upgrade and changelog.

Regards
Arrio Antonelli

nanov2support 2024/06/19 16:14

Hi,
We are currently just running through the extended stability test (fuzz
test) and ironing out one remaining crash. Since most of our customers
demand stability as the highest priority, we have to ensure every release
is crash free. Sorry for the wait and hopefully the next version will be
ready for release soon.
Thanks,
NanoRFE Support

I personally appreciate stability. I’m not a beta tester and don’t want a bricked unit 😊

Thanks

shoud not a new release have the date of the release (for user easier to
keep track of fw versions)

but in june 24 talk about a july 23 release?? HMM?!?

just think that the release date should also be updated ... not??

........ a thought from a dumb nut :-)

Hello,

the issue is different.
New update has been announced several time and with goal date but never released.
Now they announce a minor release for 11 of July.
I ask when the major update will be rleased and also will be apreciated a changelog ... but never get a real answer from @nanov2support

If you like stability is anough do not update your item with new software.

Why are most calibrating or updating firmware so frequently as this is not a precision instrument and never was intended for commercial or industrial applications, just for hobbyists.

Rob Rowlands NZ6J 2024/06/26 23:25

Calibration is necessary to compensate for cabling. If you don’t care about a
dB or so may be you can get away with no cal unless temperature changes.

Dear nanov2support,

Many decades ago, there were devices that didn't actually run software, but only some digital logic circuit did the job ( such as a DMM). - Without a doubt, these devices was rock stable (or even those weren't stable). Nowadays, software updates make it possible to add extra functions over time; - A nd always increase stability - there can always be mistakes.

Supported devices with new software released at least every six months or annually is the general practice.

I would be particularly interested in fine-tuning the reference clock, even after possible replacement of parts (better TCXO). This is included in the software of competing products. Is there a possibility for this here as well? Does the factory calibration (only) mentioned in another post cover this setting?

István

Dave (G1OGY) 2024/06/27 17:27

And calibration is necessary when you are working on kit for the higher
bands.
There's no way my HB 13cm dish feed will exhibit similar characteristics to
my commercial 9cm feed.

Dave, G1OGY

Congrats on earning a block based on your incessant spamming the list.
What a useless poster.

@nanovnav2 I suggest banning him, he's ruining the experience for everyone
else. Customers like him have negative value.

I don't know where you live (and given your behavior I'm not interested in knowing) but I live in a free world.
A world where everyone is free to express their opinions without offending people.
And since I haven't offended you (unlike you) I think I can continue asking.
I will stop asking the question when I get some clarity on the topic and answers from @support.
If you are not interested in my posts you are equally free not to read them, but remember never to offend people!

W4JDY1953_G 2024/07/12 10:52

Sound advice.



When I have the time from my weapon system engineering, work, I will look at the device’s accuracy, precision and error figures to see if and when calibration is truly required



Interesting comments on the use of this unit by Moonbounce operators and the one person interested in using the device as a radar emitter.



Caution of using Windows 11 Pro … w/o some tweaks beyond making it User friendly, it has problems running any older 32b software, so be careful before upgrading your OS. I keep an old but battleship grade HP 6470b for such firmware and older apps usage.



Correct assumption as to acceptable losses that all depend on your application. So before tweaking this device and bricking it, see what you usage requirements are in terms of the accuracy and acceptable errors.

W4JDY1953_G 2024/07/12 11:04

A proven example of selected freedom of speech.



That is what the delete button is for.



There is no customers here, but a User Group.



Interested in the use of your device in what exactly what task or profession? That helps to ascertain you needs for what appears to repeated calibration.



I find the application of these marvelous devices degraded by the same daily calibration activities.



There are so many tasks within a hobby and some lower-level engineering and technical work not demanding a certified, authorized calibration facility that this device can be used for.



In amplifier design, I find it a quick and dirty tool; but in antennae, one has to be careful that the DUT is not compromised by transmission lines or waveguides not being properly matched and tuned.



I have used this unit for LF thru SHF work, and it gets me to where I can see the need for or no need for final design refinements.



Thereafter, if for a commercial, industrial or military contract deliverable, I then pull out the Big Gun test equipment.



These professional devices too suffer from lousy Cyber Hygiene and Health issues as patched are not periodically available or timely promulgated. You get what you can afford and what the task demands are.



I saw two of these devices used in a passive radar demonstration – that was amazing as the experimenter, a budding future engineer, was only 14 y.o. !



So, if these young adults and teens can use these cheap devices to pique their interests in a future career as a engineering or scientific profession, their value is immeasurable. I donated one of my old 1300 units to a local school, and in their science class the kids were as amazed as when they can talk to the ISS crew when I have the time from work to allow them to see something beyond the Internet to invest their personal free time into.



Eventually with M/L and AI, the need for calibration will disappear as the DUT will auto-program the test equipment to meet the User’s needs and device’s characteristic parameters.



In the meantime, have fun using these tech toys, as that is about the level of professional use I would risk using them for.



Great postings here esp. when it comes to antenna and VNA design work – I learned a few new things about the use of the device from you all these past years.

You live in a free world that I and my comrades paid for, so do not hand me that dodge.



As you stated, everyone is entitled to their opinions, esp. I so your argument validates your assumed character.



If you want to know where I live, then let’s meet.



Where in my home in Europe or here stateside – your call.



24 years and two wars from enlisted thru officer ranks ranked one through those years, followed by 8.5 years as a foreign military advisor in-country in Arabia, and back here as a senior weapon system engineer.



That’s 50 years of technical, maintenance and operational experience across 4 continents.



You offend me with your air of superiority and the question I asked was legitimate and based on years of using test equipment commercial and ones you will never see in the military.



Enough said ….

Spamming as opposed to your one-sided wokeness.

Spamming - what do you know about spamming from a security and legal side as my opinions like your free speech are not spamming.

Get a life and apply your social metrics for free speech to yourself before pointing u=your unqualified fingers at others.

Back to what this blog is for - if you want to continue your childness victimization fit, then let's take it off line between us ... leave the rest here sticking back to the topic of asking questions, and not insulting others that you cannot back up in person.
