Hi QRP, did you ever get permission from the author for those modifications? Does the application have a license? There may be some code or ideas that I could use for my application, but I haven't

you can use it with no diode. But if you want to see battery voltage, you're needs to install diode.

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? -- Bryan, WA5VAH

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

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

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...

/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

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.

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. I communicate directly

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)

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? -- Rune / 5Q5R

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...

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
