Good idea, Have a house full of visitors this week. 3663 is fine. Can do. Otherwise I will download the saver file and get ready. Thanks. Mel, K6KBE

Ken, You can place a small piece of felt across the switch opening (on the inside) and just make a few slits in it for the controls to poke through. That will keep out dust and pocket lint... Regards,

Dave, very interesting. But I'm a bit confused by the part I've quoted, above. It seems to me that the measured angles should be on the order of (very roughly) -34 and +146 degrees for open and short,

This whole CC resistor discussion is meaningless for all of us who use USB 1,2 or 3 version from host side and original USB cable !!!! They presence have only sense when you connect NanoVNA to host's

IMO, embedded firmware changes beyond trivial want debugging and logging/tracing capability, which for nanoVNA typically involves an ST-Link V2 ( < US$2, e.g. https://www.ebay.com/itm/293210793177) ..

David, It's in the Files section - under Firmware....Good reference: /g/nanovna-users/files/Firmware/Building%20the%20NanoVNA%20-%20Source%20in%20Ubuntu%2019.04.pdf

sorted, recalibrated, now working :-) Thank you Rune.

This might particularly interest Jeff Anderson, and Kurt since I know he did some work on cal kits. I thought of a reasonably simple way to define the properties of well engineers calibration kits

I do know that I haven't seen those errors since upgrading to newer firmware, such as 0.2.3. So I think that might be a viable solution in general, along with calibrating the device. If it's just a

Hi I visited J?rgen, OZ1BNN, yesterday where we tested his NanoVNA which if probably from the same batch as mine. His NanoVNA has the "non floating error" galore. We did try to calibrate but in vain.

Hi Dean, generally, you get this message when the NanoVNA sends data to the application which falls outside the expected range of valid data. Far outside, in fact. There are two steps to remedy this:

Yes, that's easy enough 2) Set up the compiler environment > What operating systems are supported? What is for the compiler / linker? This is where some sort of document would be good. 3) Make the

non float data value?! get this on both versions, once connected, any ideas anybody?

Ken, Very good looking case. Great Job! 73, Steve_WB8GRS

No professional tech writers here, sorry. Several folks have taken whacks at manuals. Unfortunately, many are not under revision control @ GitHub and best one there is not in English. Plenty of other

Oops, should be edy555; correcting...

Hi Mel, The author of the manual (cho45) is a friend of the original designer (edy555) of the NanoVNA and both gents are Japanese. I translated the manual using Google translate and cleared up several
