Beware of cheap underperforming clones

As of 2022 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.

See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

V2.4 Operating Manual

barnc4br 2020/12/28 20:37

I have worked 16 hours a day for the last week trying to learn my new v2.4 and write it down.
I am at a point that I need to stop and let other people contribute by proof reading, commenting, adding content.

Please do it with short comments in this thread or .docx files or editing this .docx with tracking on or PM me.

Thanks you.

I would love to help, but no attachment or link to manual file.

Is there a version where the spaces between words are present? Kind of hard reading.

It seems to look just fine when I download it. The .docx format is what MS Word uses. Many other programs can read and save in it as well. I use LibreOffice Writer and it's works fine. --Todd K7TFC

Using MS Word here and all the words are run together like one big paragraph.

I have a particular grudge against docx. It seems to add little to routine text documents, but needs adding or a recent version of MSoffice (kerching to Microsoft) to use it.

Before I retired, I used to have continuous battles with management who sent out important documents and information in docx format to the staff whose computers had old Office installations which could not read them.
Early users of PowerPoint will now doubt remember the issues of the host institution not having your latest version of PowerPoint and your presentation was trash, so you had to present to a blank screen (I always made acetate backups).

Doc files can be read by almost everything on every platform.

Always release something in the lowest, simplest format option which achieves the objective.

It downloads and reads just fine here.
Thank you.

If anyone else has the same problem, I got it to open correctly using Open Office.

I uploaded it as a PDF. Try that. It just makes it more difficult to comment and add to the doc with that format.

I want to add a few more screen shots and I am trying to get one with 4 markers and the trace data, but I can't figure out how to do that. With 4 markers I get the Marker data, I must turn one off to get the trace data back. Any ideas?

The latest LibreOffice should do the trick:

It's a development of OpenOffice.

I use Open Office and it displays the manual perfectly. Open Office is
free...I know Microsoft hates it. I only use Microsoft when nothing else
will work (only for software that will only run on windows).

Sorry, got a little carried away with my save as. I fixed WORD so the PDF is clean now without all the WORD tracking. Different version # also.

I would suggest to only use PDF format when publishing manuals. First of all a its a much safer file and it is universal so it will always render exactly as intended on any PDF reader. Secondly any DOC or DOCX file might easily contain macros that can infect computers, a very common method still being used nowadays, so many people (including me) will not touch them with a 10 foot stick. If no other alternative I would first always convert them online to PDF before opening, which is what any author can also use to very easily convert any document to PDF for free. Just search for "Online PDF converter" to find many free of cost and very easy to use options. The other method is having a PDF print driver installed that will locally print (convert) to PDF any document file format.
