Yeah kinda hard to find anything. And if a noob dares ask for help, you probably will get flamed for not using the search function properly type of answers. Oh and a bonus, member emails are available for anyone with an internet connection.

I forgot to add. Mine has a USB-C port.

I recent got my NanoVNA clone from Amazon.

It seems to be a NanoVNA-H clone, white case, No Gecko on the front panel and no shielding.

I am looking to get a case 3D printed (I don't have my own printer) but I am a bit overwhelmed by
the number of options on Thingyverse and the comments about some cases not fitting some NanoVNAs.

Can anyone out there help me narrow down what case might fit ? (i.e. If you have the same model and have
found one of these cases that fits, can you tell me which one).

If I had my own printer I would just try them all but it is going to cost me money for 3rd party 3d-printing and likely shipping
so I would rather not do this by trial and error (i.e. my hope is that the case isn't going to cost me more than the VNA ! ).

Thanks in advance

Michael VE3WMB

there is no drivers section on the wiki files section

seems a pisspoorly organised site!!

Thanks! Considered applying your keen sense of organization
to the highly rewarding tasks of Wiki and Files maintenance and development.

Hi All
This new release NanoVNA-H_20191125_AA from


Is great due to large text

Kind regards

Kurt

Thanks Dave,

I have no problem with it. But I feel it is good to be aware of it.

The huge number of participants means a considerable chance
that someone got a Trojan virus harvesting all emails it can get.

So not showing emails is advisable indeed.

But I don’t see any reason that the *content* messages should be hidden
from Google. Removing email addresses does have some merrit.

I suspect that individuals have a set of privacy settings that they can configure for themselves.

Problem solved !

I'm running the new Nanovna-Q software from Nov. 26.
Before calibration I did the RESET, sure. The calibration resistors are OK, I have two, one that came with the NanoVna and one from MiniCircuits.

The RESET procedure was the problem:
I did not realize that I also need to SAVE to Cx right after Reset. Otherwise the data isn't really cleared and remains in the memory.
If I remember correctly in previous firmware versions the RESET automatically cleared the memory loction without having to save actively.

Whatsoever, now it works fine again. Thanks for your inputs !

(from list co-owner) -

As the initiator and one of the two co-owners of this list, I have configured the list to maximize user privacy to the best of my ability and understanding. With about 2800 members since June, it isn't practical to screen each new e-mail address that arrives (many look plain weird, but then again as I've discovered, it's a way to be creative!)

That said, I share below the group's privacy configuration in force since day 1, and seek any practical input from any list member regarding security or privacy concerns going forward. Should you wish to contribute recommendations regarding privacy and security configuration, I urge you to reply in "private" mode (or send a message to [email protected]) unless you are certain your input is directly germane to the nanovna, as I seek to keep S/N here maximized - I don't want to launch into a long generic thread on privacy or security, and will stop threads that diverge from issues that are of immediate and direct concern to *this* group and the nanovna.

This group is and has been since inception (June 2019) configured as follows re privacy:

Visibility: Group listed in directory, publicly viewable messages

Member Directory: Moderators and Owners (who can view the member directory, there are exactly two people fitting that classification)

Members Visible: Owners only (who can view the list of members; the same two people)

Hide Email Addresses In Archives: Mask all e-mail addresses in archives

Thank you for your interest in and support of nanovna-users on groups.io.

Use Zadig 2.4 to get USB STM32 downloader driver and STM32CubeProgrammer
for downloading the nanovna firmware 0.5.2 into the device.

Interesting...

Over the past week I have casually reviewed various Li-Ion data sources, and I've seen surprising variations.

Up until recently, I had assumed that it was typical to charge a Li-Ion cells at 0.5C.

It appears that depending upon individual manufacturers chemistry variations, that you could expect to be informed
that they will recommend anything from 0.5 to 2.5C !!

But the average is 0.8C.

I'm not convinced that I need to be in a rush to change my own supplied NanoVNA cell.

The specsheet on the VNA indicates anything from a 300-500ma cell, which when supplied may have been sitting
around for a year or two in partly of even fully discharged state before being fitted into a NanoVNA.

Given that expectation, and the current draw of the vna anyway, I'm seeing 2.5 hours of use from a single charge
and no apparent overheating or explosions (!).

Of course, in due course I may see a variation in performance and change my mind ?

Not sure if I'm one of the luck ones, but I've had good fortune with my VNA (Black non Gecko)..

I bought it, it worked, seems as accurate as can be, was dead easy to re-box and just sits there ready for use
when I need it. Perfect !

Hi Roger,

The device manager shows the driver when it is working properly. There are more ways to see what's hidden. What I recommend is a utility called USBDeview, which shows you what driver programs have been installed on your computer since your operating system is running.
You can read the usage at the download site.

Green candidates at the beginning of the line are in use. Once selected, the right mouse button will bring up a menu and select what you want to do. It is advisable to remove any unknown drivers and then reinstall en.stsw-link004 (ST-Link Utility) or stsw-stm32080 (DfuSe), which will install the drivers as well. You may need these programs during firmware upgrade.
Successful use.

Yes,I have done the same.

1st test was my Tecsun PL660. The input was about 500 ohms through the external antenna socket.
Spec sheet for the SDR chip said about 600 ohms, so that seems in order, since it's a typical broadband result.

NOTE - The RX needs to be powered ON, or else the active device impedance will change.

Just for fun I measured a few of my HT's.

A very cheap and nasty Baofeng UV3R had a typical input impedance of only 11 ohms.
A Baofeng UV5R varied between about 33 ohms to 100 ohms. Oh well, a nominal 50 ohms then ;-)
A Yeasu VX7R was pretty close to 50 ohms, but still had quite a bit of variation.

It's what I expect really, for price, "widebandness" considerations and what is really expected from this class of radio.
Most RX inputs are rarely 50 ohms anyway, unless you are purchasing monitoring equipment and you're a govt agency.
So don't expect 50 ohms dead on for a consumer rig.
