I? think that you can just flash the latest firmware, than the config item will show up.

Hi Tom,
I recommend bringing your web page to your attention to better understand the possibilities of what can be done with nanoVNA.
You can also find help on the group's Wiki and Files pages.
I think you will find a solution in any of them, you will learn a lot from it.

Have a nice time.

Hi Thomas,

The python modules for me:
scipy 1.4.1
pyQT5 5.14.1
pyserial 3.4
numpy 1.18.1

it works with windows7 under 32 bits.
The pyQT5 version can be problematic, I don't know about Debian, but "path" path accesses can also be important on the system.
I mean, it's a good idea to install Python in the root directory.
You may want to use the "Search" button next to group topics with "python debian".
I hope you successfully fix the bug.

Hello to the group,
I have a version (white) which does not have a”Config”selection on the home menu.

What might this mean, in terms of version and the ability to upgrade the firmware?

Thanks,
Tom W3TMC

Hello.

Hugen already has the V2 for sale.

Soon it will have a metal casing and 4 inch screen.


More info can be found at the /g/NanoVNA-V2/ group.

Hugen,

What is the progress of YOUR version of the V2?

I am assuming you are working on a 4" V2 version with SD card slot...

I am ready to order one.


On another subject: I am now using DiSlord's H4 firmware without SD support.? I tried the H4 on 1.3Ghz

and was surprised how well my 1296 antenna appeared on the Smith chart and RL graphs.? Of course,

I have nothing to compare it to! ;-)

Hi Milo? -

But I did not know about the flag in Chrome.

Thanks for the feedback!
I guess Wiki words were insufficient; adding the screen shot may help..

Hi,
I built a Debian package for nanovna-saver (using dh-python) and installed it. However when I try to run I get the following erorr

=================
Traceback (most recent call last):
File "/usr/bin/NanoVNASaver", line 6, in <module>

pkg_resources.DistributionNotFound: The 'PyQt5' distribution was not found and is required by NanoVNASaver
===============


However Python3 PyQt5 and other dependencies (Scipy, Numpy and Serial) are installed on my system, using
Debian 10 packages which have the following versions

scipy = 1.1.0
pyqt5 = 5.11.3
pyserial = 3.4
numpy = 1.16.2

Is NanoVNASaver compatible with these versions ? Any help on what could be causing the error is much appreciated.

Regards
Thomas

Hi Bill
Nice project. Thanks for the work you put in.
I tried to find the Gerbers on OSHPark but I just get an empty page. Have you delisted the project?

Hello DiSlord;
Loaded v 9.3.2 Beta today on my H4 and things are working great. A good example of what open source software can do. Your additions to the unit Menu are easy to access. I will need some time to understand how to best use all of them. The SD card access looks good, so I will have to get a card reader as well as the 32.768 khz xtal so the time will work. I would encourage others to try your Firmware. There is no risk, the changes are a significant improvement, and it is easy to change back if you ever want to. Thanks for your efforts.

1. A full calibration to the end of the supplied cables and up to the maximum

(S11~0dB) and load (S11~-50dB) standards to ch0. However, when I connected the
thru standard, S11 was between 15-20dB at most. This sounds really poor, given
that the thru is supposed to be a matched 50-ohm connector.

The port 2 input impedance is not perfect 50ohm, this may limit S11

2. Measurement of a microstrip double-stub bandstop filter at 1GHz showed an
S21 curve that unnaturally flattens out at about -20dB from approximately
900MHz to 1.1GHz, rather than dipping down to about -50dB, which is what
full-sized VNAs show.

Was this measured at the end of a cable or directly on thenanoVNA?

3. All my measurements show something weird around 900MHz, like a
discontinuity in the curves. I know that the NanoVNA-H switches over to the
3rd harmonic from 900MHz to 1.5GHz and the dynamic range is reduced, but why
shouldn't the curves be continuous?

At 900MHz the nanoVNA switches to the 5th and 7th harmonic. YOu may try to use the 'threshold' command in console mode to change this switchover frequency a bit higher or lower to see if that improves

4. Finally, just a question: has anyone had luck finding the properties (e.g.
capacitances, inductances, phase offsets, etc.) of the supplied calibration
standards, so that they can be entered into NanoVNA-saver?

Hi Oristo,



I use the standard MS driver in Win 10.
I found in the discussion it should be OK.

But I did not know about the flag in Chrome.

I enabled it and everything works as expected now.

Thank you!




Milo?

Hi! I'm new to this group and just received my NanoVNA-H. I discovered some issues, and would appreciate the advice of members in this group on the following four questions. Thanks in advance!

1. A full calibration to the end of the supplied cables and up to the maximum frequency of 1.5GHz gave me good results when I connected the short/open (S11~0dB) and load (S11~-50dB) standards to ch0. However, when I connected the thru standard, S11 was between 15-20dB at most. This sounds really poor, given that the thru is supposed to be a matched 50-ohm connector.

Hi Oristo,



I use PC and Win 10 64-bit.

I tried to copy&paste the link to Chrome and I opened the link in the Wiki
also (using Chrome).

The result is the same - not found.

Should not I enable anything in Chrome?




Thx, Milo?

Herb,



thank you. I tried Saver and it works for me.

It is up to me now lo learn how to use it :-)

Milo?
On your Win 10 64-bit I would suggest running one of the PC applications
instead of the "cho45" web application. I consider Rune's NanoVNA-Saver to
be the best choice but other user's have their own favorites. These are the
ones that I know of:

1. NanoVNA-Saver, currently ver 2.2,
saver/releases/download/v0.2.2/nanovna-saver-v0.2.2.exe .
2. NanoVNASharp v3.0,
1082&sid=0b5abe5618b45cdf3d84fcf7ae9d42b2 .
3. nanoVNA Partner, .

4. TAPR VNAR4.6, /g/nanovna-users/files/NanoVNA%20PC%20
Software/TAPR%20VNA/VNAR4.6.zip .

All the above applications are described on this group's Wiki page at
/g/nanovna-users/wiki#Software . Recently RigExpert has
released a PC software that supports the NanoVNA but not many users have
been able to get it to run on the -H4.
