I've got the Smith admittance plot running. I assume people use mS rather than S to avoid tiny numbers. Is that right? Brian

It's a false positive. First of all, download the latest security intelligence update from Microsoft. I just did, and it does not flag the file as a virus. Another way to check is to give the URL

Brian, F.y.i. When I click on the word program on your page https://k6sti.neocities.org/splot.htm then my Windows 10 pc? finds a virus and does not continue to download. 73, Kees PE0CWK Op 29-4-2025

Mark, How is your H4 connected? If a serial USB cable, then COM port number rather than IP address. Device Manager will show the COM ports you have. 73, David GM8ARV -- SatSignal Software - Quality

Did you go through those calibration steps on the application or the Nano? If on the application then you must be connected successfully. You calibrate on the Nano only when you want to use it as a

Using nanaovna-saver, on a -f, I noticed that sometimes the circle on the Smith machine (on a simple capacitor, for example) could be larger than the grid circle. Now, systematically, even before

I have the NANO H4 connected to my laptop and the app is running. However, I see next to the <DISCONNECTED> is a field where I am supposed to enter an IP address?? I do not know the IP address or why

Why not have a serious read of the information in the WiKi on this site? There are several excellent guides there. Dave - W?LEV <d.milivojevic@...> wrote:

It depends on how different the results are. Remember, the FW interpolates Saver can do unlimited (in theory) number of points. It will just do the required points in segments. For H4 that would be X

I've posted the s-parameter Smith plotter here: https://k6sti.neocities.org/splot.htm Please read splot.txt to learn the obscure tricks (like how to display a Smith plot!). I will try to free up some

Yes Reset first and then calibrate If what you are measuring does not have sharp valleys and peaks in SWR then you can just reduce the stimulus range on some NanoVNA's (like the -H and -H4) and the

You got it! Yes. Dave - W?LEV [email protected]> wrote: -- Dave - W?LEV

I'm real time on my H4, so hope this maps to yours. QUOTE (Dean, W8ZF): This just confuses me again. "Remove the calibration and save that to the default slot (0 slot) when using NanoVNA Saver."

Can anyone direct me to the latest SAFE version of nanovna-app? I went to GitHub and found a branch under DiSlord. There is a Win32 release of NanoVNA-App.exe from 2 months ago. When I try to run it,

Dragan, This just confuses me again. "Remove the calibration and save that to the default slot (0 slot) when using NanoVNA Saver." Remove *which* calibration? And save *what* to slot 0? Are you

AppCAD. Brian, I mentioned this way back when you started this plotter project. It is now available as....https://www.broadcom.com/info/wireless/appcad And is the old HP semiconductor group, formed

No relay to switch the source to the second port. (and no bridge on the second port, either) The NanoVNA doesn't use a directional coupler - it's a straight up bridge on Ch0 and a pad on Ch1. Now that

Brian, Ahh yes, the old HP AppCAD program. I loved that thing back in the day. Not perfect, but a pretty decent tool, and you can't beat the price. For those looking for more information on this
