To test properly I would need to uninstall all 5 dependencies.

It would be nice to understand what is going on here before I do that.

There are now several new features. One seems to be scale for the delay. I have check this, so this may be no problem at all.

I have some 32cm teflon coax with an open end. I see no TDR from NanoVNA but I see a proper TDR from NanoVna_saver 0.22. Frequency settings seem to matter with TDR too. My frequency range was 50k-500M at first and TDR wasn't right. I wish to see TDR from Nano, because it has delay in seconds and not in meters.
I just updated my VNA to 0.54.
I attached a screen capture of delay from Nano.

Not really "all"...I had no clue that a missing driver was the problem: As a tech writer, a problem I encountered often when those who have a lot of experience leave out details needed by the less experienced. Interviewing the "Subject Mater Experts" often required several interviews to get to the meat of the requirements.

As a minimum, including a lead sentence or paragraph about when and why would be a help. Some key words included for searching too, e.g., Not connecting, missing drivers and etc.

Please refer to the Wiki and Files areas as they have a pile of very good reference material, posted by a number of forum members over the last 6 months. Cheers,Larry

Many thanks to Gyula for the help; I'd have had no idea where to look for the

I second Larry's advice. There is a lot of invaluable information in the Wiki and Files sections that can save our members a lot of time and effort. This group members always seem to be willing to help with installation and new user questions, but a lot solutions have already been archived in the Wiki and Files sections.

Using Linux Mint 19.3 amd64 here.

Built 0.2.2alpha successfully on 15.12.19 using the instructions here...



Upgraded LM19.2 to LM19.3 on 19.12.19.

Now all versions 0.2.2 going back to 0.1.5 will not build with the same errors as reported in this thread i.e.

$ python3.7 -m pip install .

It seems to me...

- this is not a nanovna-saver problem
- something may have changed in PyQt5 since 15.12.19
- the upgrade from LM19.2 to LM19.3 may have broken something in the python3.7 installation.

However if I just do this into a clean directory...

$ git clone
$ python3.7 ./nanovna-saver/nanovna-saver.py

then nanovna-saver runs fine, with no "python3.7 -m pip install ."

Hi Rune,

I still find some strange things in the marker handling? :

1) I did a 2 port calibration? from 10kHz to? 1400MHz (and pressed "apply")

2) I filled all 9 marker-bars with different frequencies from 1MHz to 1400MHz

3) Then I did a sweep with CH0 connected to CH1 by a +/-30 cm long? RG316 cable, that was still connected to the VNA after the through calibration.

4) After this, the markers 1 up to included 5 on the data field were filled with data, the markers 6 up to included 9? were EMPTY. !

5) Marker 4 its color was grey so the tekst above the data field did not show up on the gray background.

6) I tried to change the color, but marker 4 does not accept the new color . (I tried several others and they did)

7) The markers 3 and 4 original frequencies that were set were overwritten both with 100.616536MHz (I had set marker 5 , to 100MHz)

I hope this is of help for this great program.

Kind regards

Jos

Using an FT240-61 core I got good performance from 1.8 to 30MHz, with less than 0.5dB loss over most of the range up to 30MHz

Optimised with 6 trifilar turns of 18AWG silver plated stranded wire twisted together. PTFE insulation, 1.85mm outer dia (CPC part number CB10433) wound on FT240-61 core.

Rune,

You shouldn't have to necessarily run the program on Linux. We Linux users can do that for you. As long as you don't use some function in Python that is a Windows Only function, there shouldn't be too much problems debugging the program. Python should be able to handle the differences between Windows, Linux and Mac as long as you aren't trying to tap some special feature of Windows. It might also help if you listed a set of dependencies required by the program and the version of Python you're using.

I myself use Linux as my production PC. I haven't found anything I can't do on Linux that must be done on Windows except for some Windows Only applications which are not cross platform. With Microsoft sunsetting support of Windows 7 today (1/14), I suspect there will be many more converts to Linux given that there are millions of Windows PC's out there still in use.

With your insight into the program, just help us interpret the error messages and we'll debug the program. A great program even if I do have to run it on Windows for a while.

Hi

I have with great success made a "portable" 1:9 UNUN and choke solution into a small plastic box like in the picture. I use it for OZ0RF with my RFzero and it was also used by KH8/OZ1RH too. The blue banana socket is where the wire goes and the SO-239 is the counterpoise. The SO-239 can then be used fur a banana plug or spare coax when portable.

The 1:9 UNUN is an Amidon FT114-43 and the choke is an Amidon FT-114-177. I consulted J?rgen, OZ7TA, who has a solid background in designing broadband HF PA commercially. The FT-114 are big enough to handle 25 W even if the SWR is bad. The UNUN ferrite should provide the matching but not dampen the signal. On the other hand the choke ferrite's job is to dampen signals. Both across the desired bandwidth.

Bo

I know engineers who spent many hours trying to find a material that would allow

160M through 6M on the same amplifier.? It is not easy!? As I remember, they settled on type 62.

If you are using hf try type 43.

If you can, get Jerry Sevick's book on the subject.

Gyula,

The PDF is a big help. After reading your previous message, I was scanning the book about NanoVNA via Kindle. Near the end of the book (?) I found a reference to the need for a printer driver; Needed before you could run the VNA to do the things previously described in the book... ;-)

Ah-hA, now I remember. Seems we did that in the early days before most software auto-installed what it needed.

The book made reference to a driver called PuTTY; so I found it and installed it, ran it, but novavna-saver didn't find it! Decided not to pursue it.

Next, I downloaded the ST 32bit driver from your PDF. Installation failed as my PC required a 64bit version. Found an updated version on the STMicroelectronics site and installed it. (VCP_V1.5.0_Setup_W7_x64_64bits.exe). SUCCESS!!

Nanovna-saver found it at COM4 and ran a scan: Useless info as nothing was connected, but it seems to be working now.

Many thanks for your help; I'd have had no idea where to look for the needed driver**. ST also has versions for W8 which were also downloaded. Maybe someone else would have a use for the info. There are 2 versions each in the Zip file, W7 and W8, of 32 and 64 bits.

Again my thanks and Best Regards.

**I tried the Microsoft site but not much help, maybe because Win7 is no longer supported.

I downloaded the kindle manual on my PC...
but I find it very very annoying to read and consult the e-book...probably because I'm a dinosaur, more used to leafing through a book than reading a PC screen...
it would be better to have at least a .pdf printable file...
