Your NanoVNA version

Siggi
 

Hey Hugen,

I've been to your TaoBao site (http://gen111.taobao.com/), but even with
English translation on the site/page, I can't figure out how to buy one.
The shopping cart doesn't seem to work for me, and I'm not sure why the
price should vary from 2-299 yuan. I guess there are different items for
sale - maybe e.g. calibration kits or some.
Do you sell it anywhere else?

Siggi

Thank you, Siggi

You can try switching the regional options of Taobao.

Hi Siggi/Hugen,
I have managed to place an order using the Chinese taobao site, which was
rather interesting as I cannot read Chinese at all :)
Hopefully you got my order in your shop Hugen !

I found a few things that were different to what I expected so maybe this
will help:
* You can enter your address before starting the purchase process. It is
under your username then account.
* Enter your address all on one line seperated by commas. If you hit enter
after each line it will show a red error.
* Use the standalone google translate page to translate your country name
into Chinese Simplified. Then you can recognise the Chinese characters when
you need to select it.
* You need to click the image of the NanoVNA which then switches the price
to 299, shown in the Red circle in Hugen's reply - the range in prices are
for the various adapters pictured. Only one option is the VNA itself.
* You need to select overseas in the option just above those little
pictures too. Googles translate says "Shanghai to the country". Pick
Overseas and then your country.
* Google Chrome tries to translate by default, which breaks the "Buy"
button so you need to turn off translate when you get to this point or use
Firefox or something else.
* Use the standalone google translate for the parts that don't make sense.
Copy paste.

Anyway I thought you deserved some reward for your work Hugen. I have no
idea if I have actually purchased it correctly, time will tell :)

Cheers,
Roger

Two bad clones have been found, they have failed to understand the role of bridge and shielding, and made some bad modifications to facilitate manufacturing.

is there anyway to know if this one is a bad clone ? This is what I have placed an order for but not shipped yet. I can still cancel it. Thanks !

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.

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

Hugen,

Are there any other differences with your design, other than the RF shields, that I should be looking out for?
He hasn't shipped it yet. He talks about the shields in the description, so as soon as I get it,
if it doesn't match the description I will file a dispute but I would like to know if there are other things that I should be aware of?

thanks

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!

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.

Greg Ashley
 

Can some one please help me to get the computer software to run my NanoVNA ?

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 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.

Hi,David

NE602 = SA602 = NE612 = SA612
http://soldersmoke.blogspot.com/2009/06/na5n-on-ne602.html

Adding shields should improve performance, but some bad modifications on the PCB can also reduce performance.

Thank you!

Thanks for sharing. Quite interesting.

I have a white Gecko unit - and I have ordered another unit from Hugen via
taobao which is waiting to ship.
I agree there are issues with the bridge.
Above 300MHz return loss measurements become quite noisy at only around
15dB RL.

I think using an external bridge connected between port 1 and port 2 to do
the RL measurement will work much better.
In that case the calibration would need to be done on a PC instead of on
the unit (without firmware mods)

Thanks, so much. I got my nanoVNA working on my computer now.

Who knows who... could, perhaps take a paid commission to make one of these nanoVNA systems but with more data points ??
