Is there a LibreVNA 2.0?

[eriklundh]

Any advice on where to buy a LibreVNA?
I have found a document dated 2022 by jankae that discuss a new 2.0 generation hardware.
But it seems to me that most of different "LIbreVNA 2.0" offerings I find is not any upgradded electronics design, just mechanical changes. like an integrated heatsink on top, heavy duty connectors, etc.
What is a good affordable source for LibreVNA?

Hi,
you can find stores with the original LibreVNA here:
https://www.zeenko.tech/librevna
There are no upgraded electronics yet. I do have several prototypes of partial VNAs to test out improvement ideas but nothing resembling a finished product, sorry.

Any "upgraded LibreVNA 2.0" is not related to me. There are clones out there and they may even be an improvement but since they violate the license and do not make their changes open source, I can not tell you what else they may have changed.

As the developer, I would of course prefer you buying the original version and not support another manufacturer who just copied the design. But obviously this is ultimately your choice. Just don't expect to get a lot of support from me when buying a clone.

Thank you,
Good to know which sources actually support your project.
The price at some of the links from that page is also better than the "2.0 upgraded" versions I found at AliExpress.
There seems to be a lot of scams or semi-scams/dropshippers/whatnot on AliExpress, since the prices of the "upgraded 2.0" versions range from 630+ EUR to almost 2 000EUR.

I know a few other open source authors that have experienced that many Chinese manufacturers view open sourec as a free-for-all, without any need for respect or reciprocity. The best of these "entreprenurs" may thank the original authors on their forked repo, where the hardware design or any modifications might not be included.
