Mike Thanks for the help, got it in. 73 Paul

No it's the other way round. If you look at the slot you will see the circuit board and the SD card contacts face that. If you miss the socket the card will fall inside the case then you have to open

Another question With the screen facing up - does the card go in with the card label facing up? when I tried to insert the card there is a space where the card could slip into the case and not be seat

Stan thanks for the info 73

Yes, FAT32. But most all cards come pre-formatted that way. And must be 32GB or less - I use some inexpensive Patriot 16GB cards from Amazon. Some cards may not work, since they need to support the li

New H4 owner. Does the mini SD card have to be formatted before use? 73 Paul W2ECK

Hello all I know this was on an earlier thread, but I was wondering what the purpose of the correct button. When toggled, it shows two different results of an SWR reading for same band. I was just won

Hi Bill , at first you can look at the kiwi section of the groups. There are many informations and links on the subsection https://groups.io/g/nanovna-users/wiki#Documentation Of course Keysigth , Nat

Keysite, R&S, and Advantest (Tek) all have general tutorials addressing vector network analyzers. Once you become familiar with the basics, you should be able to use any similar instrument. Dave - WØL

I'd be interested in those too!

Copper Mountain and Keysight/Agilent/HP both have lots of tutorial material for VNAs. The other possible source is the syllabus from a class at University of Alberta - during COVID, they sent out a pa

Where can I find detailed analysis, interpretations, insights, and teachings of case studies and examples of scan outputs from various test experiments, so I can learn how to interpret the output and

Yes, just adding the card socket should work. If you want the firmware feature that automatically names the files with a timestamp, you will likely also have to add a real time clock crystal (which yo

Well, I'm on Xubuntu Linux. I installed all of the needed software in Synaptic vs in terminal. Cloned the github repo. Built according to the readme. dfu-util is CLI only. Used the -U option to captur

Thank you Stan!

If you use NanoVNA-app, there is a "Save Flash" button in the firmware update dialog - that saves the current firmware and settings, such that they can be re-loaded. Similarly, if you use Dfuse-demo,

And how does one out load the current firmware? I was wondering if this could happen but have not seen any procedures to accomplish this task. Thanks

Some early units of the genuine 4.3 hardware came without the SD card slot installed. You can easily do it if you are handy with soldering small items. You can't brick your nano by uploading firmware.

BTW, I've also reached out to @edy555 on Twitter with the same question since ttrftech seems to be his baby.

Thanks for the tip. The firmware installed is from ttrftech. The latest version in their github repo is 0.8.0, dated 2020/06/20. It does not appear any of the ttrftech builds added the 401 point optio
