I doubt people will walk away and buy something else, because, what else would they buy?
I've bought a LibreVNA this week.
It *seems* to cover all my needs... But there is not a lot more of review available... so I hope it will be OK
I'm not a big fan of hacking, but turning a "SSA3021X into a SVA1032X" is still x3 the "500$" price.
The 6GHz is "just" a nice to have as a work around, but help to have a dynamic range of +/- 85dB for frequency < 3GHz !

If LibreVNA is a "broken" design, I will certainly buy a SSA3021X.

Wasn't there a problem with the LibreVNA's dynamic range above 3GHz? I seem to recall 50dB only. The NanoRFE V2+4 at roughly $200 goes up to 4.4GHz and is spec'd 80dB < 3GHz. In fact, the V2+4 might be the fiercest competitor to the V3, if you don't absolutely need 120dB dynamic range (which is amazing, btw).
It's easy to suggest how to proceed when you're not the one taking the risk. While I signed up, I think part of the problem was we never heard back what the specs would end up with. I want that lower frequency, wide dynamic range and while they stated they were looking into it, we never heard back. Many, rightfully so, will want to see it in action before they pull the trigger. $500 would be cheap if they could pull it off.
Hi, from a fan of some of your youtube, especially using the Signal Hound BB60C.
I'm a neophyte with a V2 and curious why the interest when you have a BB60C?
I doubt people will walk away and buy something else, because, what else would they buy?i've mentioned one alternative above, libreVNA. and me is at least a one person that is at risk of walking away. you cant guarantee all the people in the waitlist will eventually make the purchase when the product is released for sale. so judging from waitlist count is a bit irrational imho. if i buy librevna now, i might not be the early birdie anymore, i'll wait more and more reviews first to justify for another 6GHz VNA when V3 is released. or maybe wait for their 2nd or 3rd revision. and since there is no update as to what is going on in the RnD progress today, we'll start to doubt it... not wanting to take risk in production cost is a lame excuse for me, Kickstarter is there, bank of PRC is there far better than wallstreet or our bank or whatever i think. at least give us some update. if they wait for more people in waitlist, i think they will also lose some people during the time. about who need it who dont? i dont want to debate, HAM/RC community alone is there bigger than this forum, you dont find them here, you can only see them playing with their drones in youtubes and some unknown chaps also doing reviews on NanoVNA V2 there. ymmv.
At a $500 price point you can expect the preorder queue to fill slowly. This is for a hobbyist already in the "serious money" category. The more money you need to spend on something, the more you're going to question your needs to actually have it.
Today, there is a huge gap between high-end and low-end VNA.
And we should remember to be happy with that "low-end" if you compare to 10 years ago
Siglent and Rigol understand that, and full the 1500$ - 5000$ range (more than 3000$ if you don't hack), deserted by high-end company doing high-end stuff.
But there is still the 500$ - 1500$, and the question is, why ?
This range is useful to a lot of tiny company that design IoT or consumer-range product. Today, a lot of designer copy older design, and say "it should be okay".
But what if you want to check your RF path between 100MHz - 2400GHz ? You "need" a VNA.
And if you want to check what you're actually transmitting ? You need a SA.
This is why the 500$-1000$ range is so important : it's a no brainer for small company, even if it's one time of use week per year.
More than 1500$ ? Or 5000$ ? You're gonna argue, "Why now?", "Can we do without?", ... And everyone think you just want a new toy (even in the R&D team).
In my last job I had to wait for some BIG problems (certification failed) to make them buy a signal analyser, and even at this point it was after WEEKS of arguing.
Can't wait to test the LibreVNA, and see how it compare with the NanoVNA V3 next year
IMHO, the question is, can you afford to buy cheap. Can you afford to buy a $500 VNA or SA and have your product fail in certification, or in production, or in the field.
When they finally acted they invested in the wrong thing again, tools instead of brain.

I think it is really a question of risk. How much will it hurt if something goes wrong. For sure a cheap instrument is better than no instrument at all, but it has to be able to answer your questions.
I'm thinking of my time making consumer electronics. At a point it was clear that our company had to introduce WiFi, and Bluetooth, and eventually GPS and make them all coexist in a palm-sized case. But it was a struggle to make management understand that we'd have to have the tooling for it. They tried everything to escape, relying on vendor promises of magical fractal antennas instead of hiring an RF engineer and buying lab equipment. When they finally acted they invested in the wrong thing again, tools instead of brain. And it hurt. A lot.

My current employer uses both. We have a higher-end 4-port VNA with some nice cal kits, etc. But, it resides in one place, and you can't just use it when you want, and you have to baby it. A $500 VNA is so cheap that you can buy a few. Other engineers can be more thorough, and also it makes their mistakes much less costly. We still have the higher-end VNA when needed.
I cant stop laughing seeing how people through 6GHz left and right in this topic. Have any of you measured anything at these frequencies? And I assume you guys have the calibration standards and patch cables for the frequency range, right?

Hi, LibreVNA developer here..
That I'm not getting. Import goods are now taxed at the source, so this will ease the load on customs and post offices at the destination.
