Same here. My interests are restricted to <30 MHz. There are important behaviors above that, but well within the 900 MHz limit. I use mine for the bench. I have a tribander at 60', a 40m dipole and an

Aldo you are an extremely gifted educator and writer. Exceptional article! Best intro I’ve ever read on the smith chart. I wish you would write more. In fact, write a book. I would buy it! Randy

Thanks, Eric. I'm going to order it. As far as the upgraded NanoVNA-H, rarely would I use it at the 2m VHF band, almost exclusively in the 1 - 30 MHz range. My intended use is strictly as an antenna

Do a google search and down load Sim Smith. You can download your s files directly and are much informed

I bought that exact one, but with the terminator kit. A friend told me it has a much nicer case than his. It works fine. I've spend days on end measuring everything in sight on my workbench.

This one is a newer version, NanoVNA-H: https://www.amazon.com/dp/B07Z5VY7B6/

Is there a preferred hardware vendor located in the USA? I'm looking at buying this offering. Anybody see a problem? Thanks https://www.amazon.com/gp/product/B07Y53RCKW

Hi, Could you please share the STL? Cheers *73 de Luís, CT2FZI* *QRV @ 145.300 MHz | **CQ0VMST (VHF REP Monsanto)* <http://goog_717545661> http://www.ct2fzi.net <http://goog_717545661>

If you're good at soldering surfacemount (and have a microscope or by magnifying glass, try re-flowing the PCB solder pins on the nanovna's USB-C connector.If either of the data lines is not

well...I duly disinstalled the drivers several times...and actually USBDeview didn't find any driver related to STMsomething. yesterday I spent the whole afternoon with uncle Google trying to find

Let's be nice people. Most people assume the device they are working with is at fault, not the underlying platform (Windows in this case). Even a good search won't return the results you need if your

Actually, I should have said, the real axis coordinates are scaled as the real part of (1+Γ)/(1-Γ), i.e., the normalized impedance Z_L / Z_o . -- Aldo -- --------------------------------------

Hi all, A bit late in posting this, but to all those who are just starting out, and having a learning curve approaching the Smith Chart, I have put together an introductory article.? You can find it

GREAT Article, Aldo - Thanks!

this can also be a solution. The problem is not with nanovna, but with the pc operating system. If you know google you shouldn't have asked the question here.
