I have tested your nice App with a Moto e5 Android 8 and I see data corruption of S21 that changes in frequency and density from sweep to sweep. Beside that, all seem to work fine! 73, Norbert, DG1KPN

Hi When it comes to the NanoVNA numbers may be somewhat confusing. I for one do have some difficulties sorting one H/W from the other and even more so when it comes to the F/W. I would be surprised if

Very good Mario, better than my needle, will give it back to my wife. Any pencil with only plastic on the tip, and the lead retracted, works. It is still sharper than my needle. Torbjorn

bryburns, I think its always a good idea to keep in mind that the NanoVNA is a mass produced product intended for the hobbyist market. If your requirements need a certain level of confidence then your

Excellent idea! Roy WA0YMH wrote:

Let me know what is missing (bottom Wiki entry): https://oristopo.github.io/nVhelp/html/firmware.htm

I found an old Sakura "Nocksos NS100c" disposable drafting pencil laying around here that has a hard all plastic tip when the lead is retracted. It works absolutely perfectly for a stylus on this

The easiest way to imagine it is to place a 3dB attenuator on the CH0 port and measure the Return Loss with nothing connected to the other side of the attenuator so that is open circuit. The power

Return loss is a measure of the loss of incident power that is not being returned because it is being "lost" to the load resistance.

Folks, I am interested in learning how much I can trust the results from my nanoVNA. I understand that a T-Check is a good approach to evaluate VNA performance. Here are the results of a brief

Rune, if you consider supporting other VNAs too, it might be worthwhile dropping the “NanoVNA” from the name of your software. That would get around the possibility of confusion, as it seems that

I ordered on of those. Where does it tell how to hook those 4 wires up to a NanoVNA? NRST->RST? TCK->SWCLK? TMS->SWIM? GND->GND? How about SWDIO on the ST-link?

Including Android versions with success and failure reports should help sort support.

Tomohiro, Welcome to the group! We all appreciate your pioneering work on the open source NanoVNA project. The fact that the NanoVNA works so reliably when produced by so many different clone

Thank you very much for this app. I have tested it briefly on my Galaxy Tab A and am excited. -- Hans-Peter Prast, DL2KHP

Tomohiro, thank you very much for your efforts in creating this project, and for your continued effort in developing both the firmware, and any upcoming new revisions of the hardware! It is a great

Hello folks, I'm edy555, the original developer of NanoVNA. This is the first time to post this group. It's very exciting that such many people enjoy the gadget from my small project. By the way,

I would prefer defaulting to no extrapolation.
