sparseMatrix, While I agree with your thoughts the level of todays technician licensee is super low. They don’t want to study any more than the question pool and think their license will give them

You guys finally chased me out of my dark lurking corner. The nano VNA is a brilliant tool that can be succinctly described in as little language as it takes to give advice. Same with any VNA really.

I agree with this response. So many ham friends bought nanoVNAs because they were cheap but few have taken the time to learn what they were for or how to use them. It’s a fantastic tool even if just

Never buy in haste. For an instrument like this try buying a cheap second hand one and familiarise yourself first. In fact I build my own nano vna, works up to 60MHz ok. Even have all the bells and

With a different fw it may work up to 1.5 g with 5th instead 3rd overtone For testing your adsb antenna maybe good enough No way for wifi ob 2.4g For that a v2 is needed (any of the v2 will do)... If

Is it possible to upgrade my vintage clone to work with frequencies higher than 900 mhz with a reasonable level of accuracy for SWR? Obviously I’d like to work with 978/1090Mhz but it would be nice

If any of you has a 2.8 inch v2.. Just buy a bigger screen for about 10 bucks and upload a fw for that bigger display.. I have such a unit and with that bigger screen it? is much easier to read

Thank you! Yes it’s the sandwich style. I might end up going by the guidance of this board too and get a reputable v2 plus4 as I want to check SWR on my ADSB antennae. I didn’t realize there was a

Is your 2.8" in a plastic case or is it "sandwich" board construction? A sandwich board is a generic (not H) NanoVNA. Hugen was the first to produce a plastic case version and then the counterfeiters

My favorite is the "F" version. Clone sellers may use the pictures / description of the legitimate original product so links to a listing cannot provide conclusive proof. Buy only from designated

Hi Michael,Your findings are correct.Have a look overhere:https://eleshop.eu/nanovna-h4.htmlIt says:Caution! The NanoVNA only works with MicroSD cards <32GB.So less then 32 GB73sEgbert PD0EZL --------

Yes, those inexpensive Patriot cards are the same ones I found to work. But some 32GB cards also work, as do old 2GB and 8GB cards. It depends on whether the card supports the SPI mode, which the nano

Finally solved the problem. Tried official SD Card Formatter: https:///www.sdcard.org/downloads/formatter/ to no avail. Next bought five 16GB SD cards: Total $16.15 at Amazon for Patriot LX Series

Doug, is there an obvious way I can identify which version VNA I have via inspection of the circuit board? I have a 2.8” that is probably 3 years old. I do know that there is no “config” menu

Hello Giorgio, If you are considering the NanoVNA-F, the latest hardware version is now called the DeepVNA-101. The new version is the same basic machine as the NanoVNA-F, but it now has a rotary

Yes, sort of. Compare the NanoVNA measurements (like SWR, and maybe impedance values) with the claims made for your design. If they're close, you got it right. But it's really nice to have the nanoVNA

No, not a firmware difference. Newest hardware is v. 4.3. -- Doug, K8RFT

I have an early (3 years old) 2.8 inch NanoVNA (updated to current firmware, though) and a NanoVNA-F. IF you will use your NanoVNA outdoors - get the -F. The screen of my 2.8 inch -H model is

Hello my friends. Before all, thank you very much for your prompt replies! They made me realize once again that... it is better to wait a bit and decide with more thinking :-D v2 looks too costly, at

But on the other hand, the original NanoVNA is significantly lower price, and doesn't have the electronic switch on the input that is ESD sensitive. If you're going on a group buy and getting a
