Also it shows battery voltage on CONFIG => VERSION screen.

The voltage on CONFIG => VERSION screen is showing 506 mv and the battery indicator is empty. I don't have the D2 diode installed. What does this mean?

Larege font cannot be used because text cannot be fit into small display resolution.
With large display it will be possible to switch into large font.

Oristo,
"nVargs.py" is a nice little beginners Python skeleton script without the complexities of Class modules. For new writers modeling their scripts based on "nVargs.py", the following would be helpful.

"nVargs.py" returns the echoed command as part of the returned data (i.e. "# frequencies" below) :

python nVargs.py frequencies
# frequencies
50000
9049500
18049000
…..

I understand the echoed command is used for commenting in your gnuplots, but for more general use it would be nice to include commented code in your script showing how to return data without the echoed command. Having the echoed command as part of the returned data can be an impediment to further processing, where a string is contained in an otherwise numerical array.

Really appreciate your contributions to the group, especially your documentation efforts that must feel like trying to hit a moving target. The pace of on-going development with the NanoVNA is remarkable.

Thank you Oristo.

I forgot to put in the post the sentence:

The S11 Return Loss was *improved at 900 MHz* by about *10 dB*.

as an appetizer and I found no way to edit my post.

So, here again the link to the wiki page:

Nice Firmware

But few things I've noticed while playing with my lovely toy!

Man. that font is small! Still useable...

Also on TAPR VNAR4.5 not able to 'talk' could with the other 0.3.0 version...

how to use the NanoVNA-Saver software *Calibration settings*

/g/nanovna-users/wiki/NanoVNA-Saver_Calibration-Settings

Very nice. I hope that some folks allergic to Smith chart read this
and appreciate how it helps typical VNA tasks.

so, this firmware /g/nanovna-users/message/5445 has more bug fixes and improvements in comparison with 0.3.1 :)

Yes, firmware 0.3.0m already has fix from version 0.3.1 from @edy555. :)

Actually the bug which is fixed by @edy555 in 0.3.1 was missing from 0.3.0m. It was already fixed.

The same other bugs which currently present in 0.3.1 from @edy555 already fixed in 0.3.0m.

0.3.0m missing sine table removement from 0.3.1, but it won't affect functionality.

Ok great! Thanks. Larry.

You selected the wrong converter - just like I did.
Select I want to generate a DFU.Then, click on the S19 or hex button - not the bin.
That should do it.

Edy555's version had a few new menu items such as DFU menu, version info, and
a few more Format menu's (not available in Hugen's firmware).

OK, you may have missed that there were already two (now three) menu maps
to match firmware menu differences.
The second map already showed DFU, version and more FORMAT options.

Since my hardware came with Hugen's firmware, I would like to confirm that the
VNA shall work correctly irrespective of the firmware I load?

I communicate directly with neither edy555 nor Hugen.
IMO, Hugen releases to Google Drive have been more stable,
and I prefer his AA versions (2 trace with larger font).

My impression is that edy555 is working on his own NanoVNA (2),
which is one reason that Hugen's are now named NanoVNA-H.

QRP reports that edy555 0.3.0 firmware has bug fixes,
better noise floor and more precise measurement.
I am concerned that touch display usability may be appreciably poorer
and whether routines no longer in-lined have been vetted for reentrancy.
I suppose that it also has smaller (4 trace) font;
4 traces on touch panel is not worthwhile to me..

ok just downloaded 0.3.1 build.
I generated with the dfu file manager, the ch.bin from the build but
all i get is a 301 byte file. it processes it too quickly, so i dont think it's successful.
Hmm...

Hugen's firmware was an early Oct build - if I remember right "NanoVNA-H_20191009.dfu".

Edy555's build is 0.2.3 which I note has changed to "0.3.0-20191020.dfu". (I plan to change my firmware tonight)

Some of the differences I noted was that Edy555's version had a few new menu items such as DFU menu, version info, and a few more Format menu's (not available in Hugen's firmware). Yes many of the menu's don't make sense and I am glad its just not me! Congrats on the fantastic effort to build the menu structure which is so help for a newbie like me.

Since my hardware came with Hugen's firmware, I would like to confirm that the VNA shall work correctly irrespective of the firmware I load? (Hugen or Edy555).

Regards - Nan

Just answered my own question, then get more excitment than i bargained for :-) ...thanks guys.
0.3.1 fix ??... no Rune,didn't know 0.3.0 existed til now..

Do you have the 0.3.1 fix from edy555 in as well?

Aha September firmware with 1500 span 0.2.3 no battery symbol.

The firmware that I mention above supports 10 kHz - 1500 MHz range. The battery icon bug is fixed. And it is more fresh, it is based on 0.3.0 version from @edy555.

Aha September firmware with 1500 span 0.2.3 no battery symbol.
Uploaded October 11th firmware battery symbol appears! Yay.
Now to recalibrate...

Not every si5351 can be stably overclocked to 1200MHz. As the temperature
increases, the internal VCO operating limit frequency of the si5351 will
decrease. If you notice a significant spike(>0dB) in your nanoVNA at 300 MHz
or 900 MHz, I recommend that you use the 800MHz firmware.

You can check your hardware with this firmware: /g/nanovna-users/message/5445

It includes latest changes from @edy555, @hugen79, @qrp73 repositories and performs si5351 PLL check. If you see red PLL icon near battery icon, it means that your si5351 works unstable.

Also, this firmware supports @cho45 NanoVNA WebApp and has no freezes and errors. :)

I set threshold to 295 MHz

Hugen set 266 MHz for his 800 firmware versions.

g8ac9166 part is the build number

It is a git change hash

this is his build release notes

screen speed will be significantly slower

which means that higher priority activities
which do not successfully save and restore context
(e.g. run out of space) will more likely provoke errors.
