Hello Everyone,

I’ve been away a while. Been catching up quietly reading the posts. I have one of the original nanoVNA clones (white) that I was never able to upgrade the firmware on with my mac. I was thinking about getting the SAA2N by Hugen and was wondering what the consensus is in the the whole version 2 and the upgrade with the N connectors. It looks great. Are there issues with version 2 that one should wait for an updated design as we have seen with the original mini with the F and H variants? Thoughts? Hugen mentions that his new version “N” has some concession for updates? Accuracy?

Thanks,

Vince

You can also wait for the V2 Plus4 which will have 4 inch display, 4x faster sweep (400 points/s), support up to 4GHz and has 70dB dynamic range to 3GHz.

Right now I have evaluated a few large screen V2 clones and the only one I know performs acceptably is the 3.2 inch one. The price is trustworthy at $100-150 for 4 inch and $70-90 for 3.2 inch, if the price is too low they may have used worse accessories or parts.

So, you were able to test the 4 inch version with N connector and it has a problem? What problem are you talking about?

Hugo,

How are you?


SAA2N uses both quality N connectors, cables with N connectors and most
importantly good quality N calibration kit.

Either wait for OwO next release or SAA2N you will be ok.

I agree that there are some manufactured SAA that may have some quality
issues (not aware from what manufacturer) however both OwO recommendations
and Hugen's products are the way to go.

Hi Luis,

Under recommendation here, I have already ordered the SAA2N.
I had no idea that new products were coming very soon.

I just hope the version I bought from Zeenko will be of quality and that software development will continue for a long time and not abandoned following new products ...

73!

The V2 version I bought on Tindy from Hugen was disappointing to me.
I will refrain for now to support this "business".
Hugen saw all the problems in the mail from Maggie.

Пипец перевод, хрен поймёшь что ты хотел сказать!:)

Aleksander,

I expect in the mail exactly the same.

Can you tell us about the problems you had?

This microbe has two problems!
1. Small display on which nothing is visible.
2. Calibrations are not saved.

Ok!

But the SAA2N that we are referring to with the N connectors made by Hugen but sold by another marketer has a 4 inch screen ... Regarding the calibration, it is not a problem of the product but from the firmaware ... This is not a bug or poor design. I just hope that a developer will continue the great work that has already been done.

I know, I have been following this project from the very beginning.
I hope to solve the problem with a small display (bought a large display).
As I understand it, the calibration problem cannot be solved.

Aleks,

In fact, what I understand is that this way of doing things is not a bug but desired during the design. There is surely a way to further improve the procedure but it takes people able to listen to needs / requests and write it down ... The product has potential but it takes feedback from users and people to code ...

He has no potential, everyone will forget about the microbe as soon as the next version comes out with the same range and price, in which the calibration problem is eliminated.

I haven't sold any products on "Tindy"? Are you sure you bought our products?

So...

First things first.

Hugen does not sell on Tindie.

One cannot compare nanoVNA-H with SAA2 firmware.

What you said is not 100% correct, and it's user misunderstanding about the
tool itself.

V2 holds calibration and saves it. If you change frequencies either you
recall again calibration or do calibration again.

That is from OwO SW feature. I agree with it up to the point it reminds
user that it's using different calibration for the frequency span.

This feature was discussed already many times.

About the display... I cannot understand who wants to use the display if
nanovna-saver exponentially enhances the usability, including the saving of
infinite calibration scenarios?

;)

Please give me a case model for a 4-inch display, no where?

Connecting to a laptop makes the microbe stationary, mobility is lost!

Hugen,

Is this your product sold here at Zeenko?

C$ 93.50 | SAA-2N NanoVNA V2 3GHz 2.2 version 3000mAh

Yes, this is Maggie's shop.

Hugo,

I suggest you join

/g/NanoVNA-V2

You will find more specific information regarding the SAA2 and their
variants.

Also some reviews about SAA2N.

Cheers,
