Hi Stan and Dave Thank you very much for this very usefull infos and comments about the advanced DiSlord function for coax measurements . I will try it and will enjoy it soon. 73's Nizar.

If it already Has the firmware needed for tunning above 1.5GHz, that would be nice... I know the V2 or LiteVNA are better for those frequencies, but this should get me started...

Hallo, ich habe das Problem das mein NanoVNA als USB Gerät erkannt wird und ich habe kein zugewiesenen COM Port. Somit kann ich mit der App auch nicht drauf zugreifen. Welchen Treiber muss ich für Win

Many many thanks, mate. It helps me a lot. Finally able to fix the issue. now it is working fine. Again thanks. 73 S21APJ

I am also using windows 11. First I would remove the driver you installed as I have a feeling that is causing your problems. For the record, I didn't even bother installing a driver and on my system i

Hi all, found a Python library - https://github.com/Ho-Ro/nanovna-tools but unfortunately this one can not read all/selected files from the SD card inside the nanoVNA-H and H4. Anyone has a link to su

That is OK, because the upload to the PC reads the complete 128KByte from the flash including the unused bytes after the program at the memory end while the FW files of about 100K contain only the pro

Dear Roger, thank you very much for reply. In the meanwhile problem solved, it was the usb cable which was interrupted inspite of looking like brand new. That is why I thought that might be a W11 driv

Not to be captain obvious, but on your nanovna calibration, did you reset cal first and click done when finished? I easily forgot and made this mistake early on and got weird results. Bryan , N0LUF

Murphy is a ham also…. However he gets on the air and into my set very sporadically. Usually similar to the trouble shooting suggestions in the latest Ham Radio Workbench podcast. Remember to check th

DiSlord, Correction: My tinySA shows it on the "VERSION" screen, while the NanoVNA does not. But this is also more a topic deep in the HW/FW - we should discuss this on GitHub. Are you still using you

Robin, Good hint, should work for the bigger ones now - untested because of the HW not (yet) available. Martin usage: nanovna_remote.py [-h] [-d DEVICE] [-n | --h4 | -t | --ultra] [-z {2,3,4}] optiona

Thanks. Downloaded and having a good read. Regards Rob aka G4ZEO

I tried to remove the screen, loosen the screws, use it without the screen, but the problem is always the same: it gives me the first drop-down menus but not the submenus. Please help me, I need the n

I have an H4 with latest DiSlord 1.2 firmware. But all of the SD card support firmware was done by DiSlord, and was introduced several versions ago - and it uses the same SPI interface on all of the h

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

Have been using my nanoVNA-H to tune my antennas for the lower bands in ham radio for over a year. It has been a lifesaver! I started to use it recently and it seemed to complete the calibration proce

Sorry about my late entry.. just joined. The ripples on the original 70cm VSWR image are the sort of thing regularly seen in microwave waveguide return loss measurements. These RL/VSWR ripples indicat
