Github has an issue tracking feature if you would like to start using it.

While porting my other VNA software to use the new common code, I noticed a few major problems with both the original and V2+ programs. These have now been corrected.

Note that I combined both into a single repository. The repository for the original hardware has been removed.

Just a quick note.
My NanoVNA H4 arrived, I then loaded the latest Dislord firmware (1.0.53 with 401 data points) into it.
Lo and behold it behaves itself very nicely with Mr. Smith's software, which eats up the extra data with ease.
3D charts take a little longer to display, but that would be expected.

Toodle pip.

Good to know. Also smart idea to document the firmware.

Jankae's unit appears to be available but I'm a bit uncomfortable with some of their description. Software seems lacking and I'm not sure if they have it open to where I could port mine over to run with it. I wonder how it would compare with my old Agilent.

Speaking of the Agilent, I finished up the port which lead to a few more changes to the software. I've added a few new features, finished up some of the other features and made a few enhancements. The changes have now been wrapped back into the Nano software. I need to update the manual and plan to make a short video showing the differences.

Morning,

Jankae's unit appears to be available but I'm a bit uncomfortable with some of their description.

A £350 punt is a little more spicy than £50.
100dB dynamic range is attractive (up to 3GHz), as is the 3 in 1 VNA, sig gen and spectrum analyser choice.
It might be the answer, but might also be a donkey.

I wonder how it would compare with my old Agilent.

Only one way to find out. I'll chip in if you fancy a gamble.

If the software is like the first two I looked at and the interface is not well documented, it could be a waste of time. Odd they didn't provide a link to the designer's Github project. If you read my early posts on the V2+, OWO pointed out the need to add the cross coupling to the calibration model. I wonder how many of the problems (port mismatch between ports, poor performance above 3GHz....) are a result of the software.

I haven't spent enough time looking into if it can be used for narrow band parts. IMO, that was a big miss with the V2Plus design.

It may be worth waiting to see if the designer comes out with a third generation that improves some of the performance problems. We may also find that the open source software starts to support it. At $500, I doubt you will see much hype from the radio group about the next antenna analyzer. If they were smart, they would drop some of these off to the main RF channels to do a review on. I'm sure that would clear up a lot of the unknowns.

Hi Peter!
I have the same H4 as yours and I also downloaded Dislord Firmware 1.0.53. Does not work for me Mr. SMITH's Software! Can you give me advice? Now I get this status when connecting Nanovna

Makes perfect sense. I'm in no rush whatsoever.

Quite. Anyone know the designer?

Mr. indman,

Correct COM port?
Cable plugged in to the hilt?
Double tap on link button?
Config/Connection set to usb?

No other ideas I'm afraid.

1. COM port correct - COM9.
2. Cable plugged.
3. Double tap on link button -yes!
4. Where should I watch these USB settings? Is it possible in more detail?

VNA Config menu... connection... select usb.

Which version of Mr. Smith's software are you using?
I'm on 1.06.

I showed you a screenshot of the program- NanoVNA V2+4 rev.0.10

Wrong version.
You need the type for original Nano.
https://github.com/joeqsmith/NanoVNA_Software/blob/NanoVNA/NanoVNA_original_1p07.zip
seems to be the latest

Many thanks, Peter!

Now I see a connection.

Video showing some of the changes to the new software.

joeqsmith · « **Reply #891 on:** April 11, 2021, 06:13:35 pm »

The new documentation and software for both the original NanoVNA and the V2 Plus have been uploaded. There were no changes from what was shown during the video. There are other changes that were not mentioned. The main one you may have guessed from the video's thumbnail is when making full 2-port measurements, the menu was changed to make it more generic. Having SWR was more a test case and really was just taking up space. The Smith charts sizes were increased and polar transmission graphs were added. You will also notice that I have added addition readouts for the cursors. Most of this stemmed after porting the software to my old Agilent which is a 2-port system.

Looking through the comments on Jan Käberich's VNA, it seems like there are a lot of basic problems being worked on. They made the group public for viewing.

https://groups.io/g/LibreVNA/topics

This post from the designer on the 9th pretty much sums it up where they are with the project:

"jankae Apr 9
Hi Herb,
so far, only a few beta testers had the hardware so I didn't bother with creating proper releases. Since the project is now officially up for sale, I will create a new release this weekend (the github actions are really useful but not exactly easy to find for new users)."

Paying for the pleasure of of helping with the development may sound fun but I'll continue to keep a watch out for it in the future.

Get the credit card out, fix it, then send them an invoice and charge like a wounded Rhino.

Did you ever get a pull tester made? If so, how did the results compare with my software and your Nano?

I am a bit stumped on "labview runtime 2011 or compatible". I have the original NanoVNA software, version 1p08 (NanoVNA_original_1p08.zip) and I have the LabVIEW runtime 2020SP1. But the NanoVNA software says I need labview runtime 2011 or compatible. Can you clarify what does "compatible" mean? Is 2020SP1 alright? It is entirely possible I have done something wrong not actually related to the LabVIEW part.

Assuming that exactly 2011 is needed, is there a way of getting that proper version of LabVIEW runtime without registering for an NI account? The manual suggests that some versions of the NanoVNA software might have it. I see a large multipart zip in here: https://github.com/joeqsmith/NanoVNA_Software/releases/tag/0.10 Is that what I am looking for?

Thanks.

Yes, download all 21 files, unzip and install.

joeqsmith · « **Reply #897 on:** April 15, 2021, 07:14:06 pm »

Do me a favor and don't uninstall the wrong files. Someone else had posted an issue about LabView not working on their system and I wondered if they had installed the newer release as well.

Of course, I suggest reading the README file and the manual BEFORE you start trying to install and use it.

gardner · « **Reply #898 on:** April 16, 2021, 04:10:08 pm »

Okay, I am up and running and getting useful results it seems. Thanks for your assistance.

I am a little puzzled by segmented sweeps. With so few points in the built in frequency sweeps on the original NanoVNA, it seems that it would be useful to allow segmentation of sweeps for the "Main" tab -- SWR. Smith chart and so forth. But when I tried that, it looks like I get a sequence of charts, updating once for each segment, rather than a single chart with all the segments on it. I will experiment a bit more.

Thanks again. This is a really great project and I very much appreciate your efforts on it.
