Although you have a new Nano - it may have a weak battery.Measure it after charging - it should be around 4.2v but no higher or lower with a full charge. (Charging higher than 4.2v might cause battery

That's is normal. This is just because you're using different diode than hugen79. you can install firmware 0.3.0m, then enter to CONFIG => VERSION menu and check voltage for fully charged battery.

I installed an axial 1N4148 diode at D2 and I now have the battery icon on my device (PCB version NanoVNA-H V 3.2) I have firmware version NanoVNA-H_20191018.dfu installed.

also AA firmware shows marker frequency with cut off hundreds of Hertz, because it doesn't fit due to large font

AA firmware from @hugen79 uses two tracks only. So, it requires twice smaller display text width and this is why it can use twice larger font.

These problems already fixed in 0.3.0m /g/nanovna-users/message/5445

- very interesting, indeed -

Hi John - Great! If you would try, in Terminal: # with nanoVNA powered off, enter: ioreg -p IOUSB -l -w 0 | grep "USB Product Name" > without # then power on nanoVNA and enter: ioreg -p IOUSB -l -w 0

I see that you linked it, rather than put the content on there. I retract my comment :-) Though I still think it should be made into a wiki page that can be edited. -- Rune / 5Q5R [email protected]>

I would normally consider it quite rude if someone were to re-post content I wrote on a wiki without my permission. That's why I asked Wes to put it there himself. -- Rune / 5Q5R

That is my conundrum for SDR with a loop antenna, which needs low impedance for wide bandwidth, but baluns to drive coax from it without killing antenna bandwidth appear themselves doomed to low

Hi Wes, thank you very much for writing this guide! I think you should consider putting it on the wiki for this group, so other users will have an easier time finding it! -- Rune / 5Q5R

Oristo, It is my understanding that |Z|50:200 does not work the same as |Z|12.5:50 for a broad bandwidth on the same transformer. To get the broad bandwidth, the primary on a transmission line

Ok, so, NanoVNA-saver works under Ubuntu, RedHat/RHEL/CentOS, whatever.? Instructions are available, which is nice if they fit your needs. But I don't use those distros, for a lot of reasons but

Just installed 0.3.0 and it worked fine until I tried to run it with NanoVNA-Saver. This is what I got:

Hi, mine is working fine under Catalina 10.15. NanoVNASaver found the USB port immediately when the VNA was connected and I just clicked to connect to it. Good Luck -- John (VK2JON)
