Re: Nanovna-H4 / F - Very Large Font Firmware?
Hi Larry,
Thanks for the reply. I don't think code written in 2019 (for the H variant) will work on the H4 or F variants; they use different hardware architectures.
That would make this a feature request for the current H4 / F line up, as of March 2022.
Regards.

Just make sure if you have a good RF choke on that J Pole. They are notorious for radiating off the coax feedline. They also de-tune quickly if any objects are in the vicinity. Roger

Re: Proper way to measure length of _Window_Line_?
Just to bring this thread to a proper conclusion:
I finally completed my measurements. My window line was 202 3/4 inches long, so 5.150m. Sweeping from 7-17MHz showed a crossing of the R line of the Smith chart at 11.410MHz. With wavelength = C/frequency, I got 26.27 meters as a full wavelength and 6.569m as a quarter wavelength. 5.150/6.569 = 0.7840 for the velocity factor, close to the spec that Bob found of 0.80.
Thanks, again, for everyone's help and advice. Now, on to building the folding J-pole.

Re: Nanovna-H board upgrades
Thanks to the forum users, the bug is with the program developers. A script that uses Java now works with a hack. The solution was posted on another forum, I posted a fix, it works for me now.
So the problem is SOLVED.
Sorry for the annoying mistake, thanks for your attention.

Re: website language selection (HA3HZ)
Hi Jim,
I found a solution in the forum for the Google translate module to work. It was a problem for others as well, so I have already found the solution as many users. Thanks to the users who provided a solution on the forum.
I hope it works for someone else now!

Re: #general SD card function on H4
#general
Mine is a 2GB only.
It's big enough for my fun!
As you can see in my attached pic, my problem is limited with bmp (screenshot) files only.
They are created but 0 lenght.
All the rest works well.
Many thanks for your kind reply.

Re: #general SD card function on H4

Hi Sergio,
My H4 had the SD card slot installed already. All I had to do to get the SD working was use a 16GB card. It would not work with larger capacity cards.

"Thinking about upgrading my very early NanoVNA to a 4" screen version. What is the difference between the H4 and V2? Which one should I go for. "
The NanoVNA-H4 has a high-end frequency of 1.5GHz. The V2 family of VNA's have high-end frequencies of 4-6.3GHz.
If you only plan on using your VNA below 300MHz, then NanoVNA-H4 has the best performance and lowest costs of the 4" VNA's. The V2+4 and LiteVNA64 are my upgrade choice for use up to 4GHz. The LiteVNA is currently my choice for testing up to 6.3GHz.
Overall, I agree with Larry and would choose the LiteVNA if I was upgrading to a 4" VNA for the following reasons:
1. It has a faster processor and more memory which allows it to have up to 1024 display points versus up to 401 display points for the V2. This is on the device itself not from the PC application.
2. It has a micro-SanDisk drive for saving screenshots and S1P/S2P files.
3. The additional memory allows more features to be added to the LiteVNA which makes it more future proof. The current firmware makes use of the additional memory by adding 4 more trace memory storage locations which are very helpful when comparing and documenting different devices.
4. It has a serial interface on-board for adding a wireless connection. This requires the user to buy and install additional components.
5. Display brightness control can be set from the "CONFIG" menu.
6. It has a real-time clock already installed. The time and date can be set from the "EXPERT" menu and are useful for automatically time-date stamping files saved to the SanDisk drive.
7. It has a rudimentary FFT function useful for comparing the magnitude of harmonics if you don't have a specan or scope with FFT on hand.
8. It has a battery level display screen display.
9. I has a floating-point processor unit which some V2's do not.

Re: #general SD card function on H4
#general
Hi Rudy.
I own a H4-clone (hardware version 4.2.1).
It came with the soldering pads free and no Transflash connector soldered on it.
I provided for by myself.
The RTC quartz was missing too and I installed it in the same time of the MicroSD slot.
When I try to save a screenshot I obtain the same error like you:
Fail write

More precisely, the writing of the .BMP file starts but it remains of length 0 and so in the memory card I find the BMP files created but empty.
I reformatted the SD card as FAT, FAT32 and exFAT also.
That didn't solved.
The very strange thing is that I have no problem instead to save S1P, S2P and firmware dump as .bin (about 250kbytes of data).
In those cases the data saving goes perfectly.
I recently reflashed again last release of DiSlord firmware: 1.1 of 2021/12/11.
I lost all my settings and even didn't solved.
Firmware bug?

1. "Is there a schematic published?"
The LiteVNA is not open source so hugen has not released a full schematic. This is not intended to impede users, but rather to slow down the inevitable introduction of LiteVNA clones. If a user wants to make a hardware modification to his LiteVNA, hugen has released a partial schematic to assist him on request.
2. "One issue with some of the later variants on the original NanoVNA is that they are *much* more sensitive to ESD (because they use RF switches on the inputs).? The NanoVNA has resistive pads/bridges and is pretty tolerant to ESD and weird voltages."
The LiteVNA uses the same input ESD protection introduced on the tinySA spectrum analyzer that hugen also manufactures. This was pre-emptive addition to ESD harden the input of the LiteVNA.

website language selection (HA3HZ)
The language selection feature doesn't seem to work on Safari, Chrome, or Firefox (MacOS Big Sur) - I think that something is not causing the translation to work, or it to re-render - If one selects a different language, it shows up as checked the next time, but no translation occurs.
Chrome does bring up a dialog offering Google Translate, which does work.
