Alan,
the green strip you mentioned belongs to the protector film. It should help you to to pick it off, after removing the front plate.

This is from the nanoVNA black. I think I almost have my head around the cal for this particular box and what traces are meaningful and which are BOGUS. The HF dynamic range is decent. You can set the traces to start from the TOP. The default is 1 box division down, i.e. 007 vs. 008.

This one was from who"
Stuart K6YAZ

Just received my 2nd nanoVNA. This is the black case, no Gecko white which works current to date quite well with 2 track display. This black case arrived ON TIME and well packed. Apparently held it's charge all the way through shipment and booted with a 4 track display.

These instruments are little like a box of cracker jacks or is it chocolate, your not quite sure what's in the box. So far, so good. This unit came in its own plastic protective case with all the accessories enclosed. The construction looks very good and robust. The ON-OFF slide switch and USB-C connector are more robust. There is a screen protector film over the display and no scratches on the display from a stylus being used on the soft screen for pretest. The style of the 50 ohm load is DIFFERENT. The short and open appear the same as with prior cal kit. Is this 50 ohm termination superior? Don't know. The prior was ~ 18 dB best case at 900 MHz. Very important, IT IS CLEAR THAT THE ASSEMBLY OF THIS UNIT HAS THE RF SHIELDS OVER THE BRIDGE AREA AND MIXER AREA AS SUGGESTED IN THE EARLIER POST. ALSO, THESE SHIELDS LOOK LIKE DIE CUT BRASS WITH PRECISION FIT. THESE WERE NOT CUT OUT WITH TIN SNIPS OR A SCISSOR AND HAND SOLDERED IN. THIS LOOKS LIKE A PRO JOB. Hurrah!

There is a green film strip sticking out of the left side of the display. Looks like the kinda of thing you would pull to engage the battery contacts on a new toy to protect the battery during shipment. However, I have not touched it and the unit turns on out of the box. The display has the 4 color traces and the pixel appearance is smaller and crisper than the white gecko unit.

So I will wait for a charge cycle to complete and see how this one plays. Hope this info is of assistance. Alan

I just checked and nanoVNAsharp.zip is there. So this should work fine. Unzip and install; in my case was done under Windows 10. There is a dll file there and a Smith Chart back drop graph is in place. That way no generation of the chart is required via SW.

Did you try this:



Supposed to have it all.

I obtained mine via a .RAR file or a zip file which I could send as well if the above does not do it.

I just tried to get the software but it was forbidden my access.

Can you please send me the link to get the software to run my nanoVNA?



Thanks for helping

Dear Hugen,
I own the two versions ( your designed version, black, with battery and shielded entries, and the "clone" white version ).
I noticed that the mixers used in white version are SA602A instead of SA612A. Do you think that will be a issue ? have you put SA612A mixers on your model ?
I have a huge performance differencies betwen the black and the white version. at 900MHz little more than 50 dB of dynamic range subsist with the black version but no more than 30dB with the white version.
Do you think that can be only explained by the missing shielding ?
(However when i made some test on HF and VHF frequencies, the results seems quite identicals).
regards,
David, F4HTQ.

I'm not sure, either, because the clone maker will steal my test pictures
directly. Checking the internal construction is an effective method.

The shield should cover the bridge and mixer completely，like the picture shown by Ernst. A precise set of calibrations is provided and nanoVNA has been calibrated.

Thank you！

Okay, but isn't that what GitHub is for?
These days with all the fancy dissassemblers available, it's very easy to reverse engineer most code anyways and it is an unfortunate fact that everything of value is copied at some point.
So, without going into great detail, are you able to say what differences are between the original NanoVNA F/W and your version? (Fixes and/or changes).

Thanks
Larry

I'm sorry Larry.
Under the GNU protocol, I should open my code, but there are clone makers who use my firmware and claim to have modified the code themselves, and I delayed the plan to open the code in order to avoid worse.

hugen,
from outside your device looks same as the "worse clone". So only a look
inside will tell if you got a good one.
So I enclosed a picture of my device, hoping it is a good clone.
Ernst

It looks good.

What do you mean by reset cal data.

Do you mean turn cal correction off before trying to collect new cal data.

What key strocks are you talking about.

Do you believe the unit is using modified readings instead of raw data to
calculate correction array

It is necessary to reset the calibration data before carrying out the
calibration.

That must be a later version design

I have a black nanoVNA and it does have a USB-C connector.

It is a micro USB connector.

I am not sure if people have confused micro USB with USB-C on this list, or
if there really are some nanoVNA which have USB-C connectors.

My model is the white gecko, but I have ordered a black one from Hugens
taobao store.

Cheers,
Roger
