Re: i need help , NANA VNA-H
Thank you I will try that :)
I basically gave up , I might be buying a rig expert zoom35 ?

Try this.. Go into Expert Settings and select Clear Config (password is 1234). Then do a Touch Cal to calibrate your touch screen. Then Save. This should restore default settings. Then try calibration (remember to reset before calibrating).

Thanks for the reply Roger!
Well, I am not a computer tech. Finally figured out that win 10 drivers
would work and there is driver loading software in the 64 bit H4 zip file. I
upgraded to DIslords
v .1.0.71. Got the H4 talking to NanoVNA Saver and NANOVNA on my tablet.
1.0.71 is an old version of firmware. Hugen has just released a new H4 version based on DiSlord firmware. Many, many new features. There are two versions SI and MS. SI is for original Skyworks clock chip and MS is for Chinese clone. If your unit was produced recently it may have the MS version and you will see an M on the label on the back of your unit. Link here >>
Unable to get the SD memory card to work. Memory chips are probably too new
and too large at 32 GB. My H4 platform is STM32F303xC Analog and DSP.
Not all SD cards work for reasons given in another post. I use a Kingston 32 GB SD card and it works fine. Roger

Re: i need help , NANA VNA-H
Nick,
In the first two photos of message 29622, it appears that the NanoVNA is in Transform mode. Did you intend that? (Transform is an item in the Display menu.)

Re: NanoVNA-H v3.6 vs NanoVNA-H4 v4.3 for SWR measurements
I've done that on the theory that the NVNA approximated the size and ground plane of a Baofeng HT. I was able to determine that the cheap tri-band whip sold by one of the recent names in the business is really only a dual band. the vendor has no clue what in the world I was talking about when I asked for test data. They couldn't put me in touch with anyone that wasn't reading talking points off a screen. I got a refund. Thanks, NanoVNA! 73 -Jim NU0c On Mon, 05 Sep 2022 11:08:57 -0700 "Dave via groups.io" <dvfuller@...> wrote: I use my H to evaluate handheld antennas with an adapter connected to the S11 connector and hold it like it was a handheld.

#nanovna-h4
Thanks for the reply Roger!
Well, I am not a computer tech. Finally figured out that win 10 drivers would work and there is driver loading software in the 64 bit H4 zip file. I upgraded to DIslords
v .1.0.71. Got the H4 talking to NanoVNA Saver and NANOVNA on my tablet.
Calibration works using commercial standards. Matches my home made standards very closely. I do mostly HF with Some VHF and UHF. I have not checked my Home made standards at VHF or UHF yet.
Unable to get the SD memory card to work. Memory chips are probably too new and too large at 32 GB. My H4 platform is STM32F303xC Analog and DSP. TCXO is 26 MHz.
Many thanks to all that made this wonderful piece of test equipment possible!

Re: cable extensions etc.
I get all of my connectors and feedline from RF Connection (www.rfconnection.com). Joes, W3RFC, has top quality products and he supports the ham community. You can see him at every hamfest in the area.
I got sme SMA Male to Female connectors from him and they have worked great.

Re: NanoVNA-H v3.6 vs NanoVNA-H4 v4.3 for SWR measurements
Thanks again :-) I've just read it. As there is no guarantee that I will be able to make repeatable measurements I will buy H model for now, make some tests with ground planes, tiger tails and different setups. When all will be well and the measurements start to make sense then I'll think about the upgrade.
Thanks Everyone.

Re: NanoVNA-H v3.6 vs NanoVNA-H4 v4.3 for SWR measurements
Hello,
I have both. I have retired the H and now exclusively use the H4.
More points to check a frequency range.
As far as requiring a metal case, I have compared my H in metal case, and the H4. The results are the same for both. Unless you are in a super noisy environment, a metal case is NOT really needed.
Myself, I would buy the H4 again. More features.

Re: NanoVNA-H v3.6 vs NanoVNA-H4 v4.3 for SWR measurements
Thank you very much Roger taking your time for explaining me all of that.
Let's say that I will manage to make repeatable measurement on nanoVNA, so without PC, keeping it in the same position and off interference.
When you're saying that rubber duck antenna is only have of the system, does it mean that when I mount different antennas to the radio some of them will have higher and some lower SWR than measured on nanoVNA.
"you will see the SWR varying all over the place" - is it too optimistic thinking that I can measure if SWR is ~1.5 and not >3.0 or you mean smaller discrepancy?
