Many schematics can be found on Hugen's github repo - some as *.png or *.jpg, but you should be able to convert them to *.pdf yourself: https://github.com/hugen79/NanoVNA-H/tree/master/doc HTH Martin

Hello Just to make your life easier when I see you having to take pictures of your NanoVNA screen. Since you are in a workshop (in the house), if you connected your nanoVNA to a computer, for example

Thank you a lot! 🙂

to be sure just connect open, short and load (with the cables/adaptors etc) that was used for calibration ... does it show a dot left right centre?? then calibration is fine and can be used ... ifg no

@Dave - WØLEV Thank you for your answers to most of my questions. @Stan, Don & W4JDY Yor input is much appreciated. Carsten - OZ1FTG

I saw that, but didn't realize they were coming in late. I'd get a few, and it just seemed that list traffic was slow.

Thanks for the reply and information. I did recalibrate and saved them to SD. But the RECALL FROM SD menu item isn't there in 1.2.14. I rolled back to 1.2.0 for now. Regards

Hi Ian, Since NanoVNA-Saver v0.5.4 was released on January 1, 2023 and NanoVNA firmware 1.0.69 was released on June 24, 2021, you may have operational problems. The release of the firmware is followed

Good point as well.

To amplify on my previous post, one application I have is routinely tuning an HF screwdriver antenna which I use on 80-10m. For this purpose, I so one 401 point calibration over that entire range, and

I normally use the NanoVNA without the computer connected, and it matches well with my MFJ analyzer. When connecting to the computer today, I saw a similar issue when measuring an HF multiband vertica

For my HF antenna work, I do a single 401 point calibration over 3-35 MHz. The nanoVNA interpolates between these so this works well for me over any smaller smaller range within that, like 401, 201 or

You must calibrate what the radio will see, not what you want to see. i.e. If you connect the VNA directly to the antenna without coax, you will see an SWR of only the antenna and it's connector. But

FYI, the drriver issue is Windows nonsense . . . Linux handles this with it's native USB subsystem, and no drivers need be loaded.

1. NanoVNA Saver calibration occasionally fails and the program crashes. --- Well, that sorta limits the usefulness of using segmented sweeps, which I wanted to demo. Oh, well. 2 NanoVNA-app --- thank
