This is a "where is Waldo" on the menu spider-web question. How do start a rescan after I change parameters? Is there an FAQ that beginners should read? A "NanoVNA for Dummies" book that you can

I realize this is similar to a recent topic but a bit different. As the "TDR" function in the nanovan is not actually a time-domain process, is there a wat to differentiate between a short or open

a useful hint when identifying torrides type 31 has resistance across the surface . type 43 has none. Different materials. -- *Gene Ruff*

43 or 31 material are appropriate for HF applications. 43 is better for 20-meters upward and 31 material is best for 160 through 40 meters. If you are sure you have 43 material, there really is no

Dears, FT240-43 Torroid, Can I use my NanoVNA to meassure my several torroids to be sure that I have the correct ones for HF UNUN? any info is welcome 73, Kurt

That is exactly what I do with my own software, but I then have to ask users not to overwrite and files they have personalise. You can't win! 73, David GM8ARV -- SatSignal Software - Quality software

** Ok but the files would be in a .zip it would happen all at once while keeping the structure -- F1AMM Fran?ois

Use NanoVNA-App https://github.com/DiSlord/NanoVNA-App

Now there is a GREAT suggestion for the Nanovna, add a firmware update option to the PC Saver program!! This way we have an “all in one” application to use and manage the nano. -- Regards, Chris

Strange, yes, but personally I prefer it that way, so that you know exactly what is being added to your computer rather than a massive install.exe with no idea what it contains! 73, David GM8ARV --

Did you check it with an ohmmeter? BTW, I noticed in the first picture that you're using/reading S21. Is that correct? And "Transform" was set to "OFF". (but maybe you changed that after taking the

Hello Thank you for the link. It's strange that we have to download file by file. It's done, thank you 73 -- F1AMM Fran?ois De la part de David J Taylor mercredi 21 juin 2023 12:39

The Nano's TDR function can show 'defect' location - even multiple "feature" locations. It shows distance in meters. You move the cursor to the "odd spot" in the trace, and read the distance to there.

Fran?ois, Gyula has already pointed you to the group (thanks). The newer and more capable TinySA Ultra has a "4-inch" screen which is adequate (for me) for many things, but there is a TinySA program

Hi Doug Do NOT cut the wire just fold it back at the insulator and tape it in place. Cheers John G4FRD --- New Outlook Express and Windows Live Mail replacement - get it here:

Don, My preference would be for the developer's effort (for which we are all extremely grateful!) to go into improving the VNA functions, especially as there are spectrum analysers in the NanoVNA

Only thing missing is distance to problem in meters or feet. You have to quess the Er.

Yes, I suppose I do, no pin so open(no contact). Lesson learned! Thank you again, Muggs KC3UDZ

A true TDR sends out a short pulse and looks at the time it takes for that pulse to return. The NANO VNA sweeps frequency and notes where the frequency when reflected impedance approaches Infinity and
