I have been a little out of touch on the nanoVNA progress. Can someone point me to a link with specs for the .V2? Tnx, Dale W4OP

You may want to download the ST com port drivers directly. They allowed me to use the Nanovna with my Vista machine even. My Win7 machine found the drivers via Windows update, so not sure why your 8.1

I have the VNA and the software running on a WIn 8.1 system flawlessly. I think you need to investigate proper drivers for your machine.

Benefits? - Don't know since there has been talk of bad clones coming lately. Some people don't mind taking chances with inexpensive stuff like this, especially with free shipping. Personally, I've

Hi Larry, they seem to be located in Shenzhen. So what are the benefits buying from them (if it original v2‘s)... The delivery time frame will be the same as buying directly from hugen or from the

Well, it had to happen sooner or later - TomTop.com is selling the S-A-A v2.2 (AKA NanoVNA V2) for $60US right now with what appears to be free shipping. Unknown if these are the inferior clones that

I just wanted to let you all know I found this info helpful and never understood the nuance of only 101 data points. I now have a better understanding. Thank you, Jason - KM6AUS

Gyula, Thanks for the tip that was the problem! I knew there was a few messages about the case but my unit touch calibrated just fine. 73! Mark KA6WKE Website: https://www.ka6wke.net

Hello Roger, Thank you very much for those interesting findings. It is good to see, that we now have the same understanding of the measuring method of the balun with the nanoVNA. In the case that a

Bill, don't feel intimidated. The VNA is totally new to the vast majority of hams. I've been using some very expensive VNA's for some 30 years. Anything I can do to promote the knowledge the new

Thanks Dave, I am new to a nanVNA and I think I am doing well with it. I have been reading documents in the WIKI and elsewhere. You have validated what I think is still a limited understanding. I have

First item to remember is that there are on 101 points across the specified frequency range. Therefore, to get any good resolution, use only narrow band measurements, like only one amateur band at a

First some background: So I bought a NanoVNA. I'm going to use it for antenna analysis/SWR setting. I figured out how to download the software updates. I installed the latest AA software. I did the

Rudi, Today I made similar tests to yours on my NooElec 9:1 baluns. I have had these for some time and cut the traces on the back when I first purchased them as I found less noise when using my SDR

Used touchstone files with Genesys to simulate real input for matching networks and the like. It was interesting to say the least but also a standard that CFS and a few other modeling system used that

Yes, I remember Touchstone run on a mainframe back in the Silurian era. It was pretty hungry of computer resources - extremely so. I could only run it overnight for that reason. Dave - W?LEV -- *Dave

Hi, I think 50 ohms its already inerent to the VNA. For 9:1 one needs only 400 ohms, |S21| I mean. Please check here:

Touchstone rep told us years ago, 80286 time, that PC version will be able to simulate the whole PCB and its currents, when PC gets a few egabytes more RAM. Well, I am still waiting.

Hello, Perhaps someone on here could point me in the right direction. I have been given an old HP laptop running 8.1. It would be perfect to use outside with my nanoVNA. I have two Win 10 desktop
