Hello, is there possible to use a "standard" way (PPA, .deb) to install NanoVNA-Saver? Thanks

Hello I had the same problem you have. For me, with a H4 also, FW originally was 1.0.39. Then i updated and up until 1.0.53 the traces work at "normal" speed. (i tested this, starting from 1.0.69, it

OK. Thank you Simec Already, it works. But I don't see the notice.

Hi Roger, Which Acrobat version are you using to open this file and others generated by the deepl translator? I have version 9 Pro Extended and it refuses to open it, saying that an updated version is

I found this online ( http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/indtor.html): [image: image.png] As with air wound inductors, the inductance for fixed ?r, the inductance varies as the

Yes the Al will vary with frequency for ferrite toroids. The reason is that the permeability of the ferrite toroid varies with frequency and the Mix (31,43, 75) etc. has a significant effect. Powdered

Use the deepl translator. It will translate pdf files and keep them in the same format as the original. https://www.deepl.com/translator/files Attached is a translation to French of one of Arie

Hi, I wrote several articles on nanoVNA measurements. You can find them in English here: https://pa3a.nl/nanovna-metingen-and-smith-chart-articles/ There's also a part about determening toriods, mu's

I agree.? It matters what you consider a good antenna.? We hams tend to want to see a 1:1 VSWR as a good value, but in the commercial world a VSWR of 1.5:1 (14dB RL) is considered acceptable.? Just

Fitst check continuity before all with and without short circuit on the antenna itself! 73 Olivier F6CNG

I understand these comments but have read so many emails where the questioner was advised to go back to a certain firmware because the “latest greatest” wasn’t working. Just my opinion. Some are

Just being a commercial antenna does not mean it is a good antenna. If you want to make sure the NanoVNA is either hood or bad, check out the antenna exactly the same way you did with the NanoVNA. I

Hello I have very little experience with toroids. I made some RUTHROFF transformers but nothing more. On my cores, I note that the Al is not constant. Is this normal ? TORUS ==== Outside diameter ?
