Is there someone in the group that can point me to a working link where I
can download the nanovna-app? This is the application that one-of-eleven
and I think Dislord produced. This app is very similar to the
nanovna-saver.
Thanks

Managing markers gets me crazy
Hi. Managing multiple markers is often getting me crazy. Is there a documentation describing it in details? For example:
1) I f I set MARKER1 with TRACKING and SEARCH MINUMUM (e.g. searching the minimum SWR), can I set MARKER2 and 3 without the said feature (e.g. to be moved freely)?
2) Can I set a marker in order to search a specific value (e.g. SWR = 2)?
3) Can I set markers with a different colour of the associated trace (e.g. SWR trace in yellow and related markersd in blue?
4) What is the exact meaning of E-DELAY?
... and so on.
Thanks for your help.

Re: NanoVNA H4, Windows 11 and firmware update
Back about a week ago somebody else had a similar problem w/win 11. (I still run win 7) Seems there are some software switches that need setting for the COM ports. (no I'm not sure which article I saw it in)

I have heard that .dfu files can be converted into .bin files. This could solve definitely my problem. However I can't find specific and accurate instructions about that.
Any suggestions?
Many thanks. ?

Thanks for the info. Question. I went to the site you referenced and saw
2 references to 1.2.24. Are these just updates to 1.2.24 or are they
complete installs? because I looked at the two 1.2.24 references and they
were each a different size.
Is 1.2.24 available on GitHub?
Fred
My current level of code on my NanoVNA is 1.0.64 .

The latest version of the -H4 that I am aware of is version 4.3 which was released about 18 months ago by Hugen. It is a mature product and there probably won't be any more updates unless some parts become unavailable and he needs to do a circuit change. He did put a better 4" IPS display in the tinySA Ultra so maybe he is now using that in the current production runs of the -H4. .
A NanoVNA-H4 running "Auto" mode outputs 0.8 dBm at 30 MHz. so this precludes using any "protection diodes" on the front end. But the input impedance is 50 ohms and there have not been any reports of ESD damage that I have read in this group. That said users should exercise caution when handling the device, short antenna terminals before connecting them and not transmit when the NanoVNA is measuring a nearby antenna.
Roger
The NanoVNA2 with the RF switches in the front end is the one that's more ESD sensitive. Roger's right on the basic NanoVNAs - there's plenty of resistors behind the connector.

So where do you think the problem is

have an H4 nano that has been working just fine with my W10 x64 for the
last couple of years. Then one day a week ago it will nolonger connect to
saver. It attempts to connect 10 times then quits.
I then used another laptop using W10 x64 and it does the same thing.
So then i pulled my original 2.8 nano out which has not been used for many
years and no updates to it. It connects and works and it works just fine
on both laptops.
One more note about my H4. It works on a unix os.
So where in rhe problem?
I plan on upgrading my H4 tomorrow to the latest code. Can someone please
point me to the correct download address for the latest H4 upgrade?
Thanks for your help.

Thanks. Since you develop the firmware. Do you know the latest hardware
revision of the NanoVNA H4 (serial number)? Or if any updates are planned?

Andrea,
The easiest way to upgrade is to use the built in firmware update feature in NanoVNA app which works with bin or dfu files. It is a Windows application that interfaces with a NanoVNA and is a very useful program. There are several forks of the original program written by OneOfEleven. I like the Owen Duffy version which is available below....
You can learn how to use it in this groups.io post

I forgot to mention, by feedpoint, I mean the point where the coax begins. ** A coaxial cable has two ends. For you, it starts on which side? I'm sure it doesn't start on the same side for everyone :) -- Fran?ois De la part de Dave (NK7Z) Envoy¨¦ : dimanche 9 juillet 2023 22:46

Latest hardware version for NanoVNA-H4
Hello,
What is the latest hardware version of the NanoVNA-H4? And is there a
(minor) update planned, such as protection diodes, or something similar?
Best regards,
