Then what does flashing mean?

Hugen is the manufacturer of the -H and -H4 and he replied to this post yesterday...

Yes. The most recently released version is v1.1.0.
If you are interested in the details of firmware development, you can find
a description on my website in pdf file or more on the forum wiki here.

The v3.4 hardware is not that old (NanoVNA started with Chinese production in 3.0).
You can see more information on my website.

OK we need absolute clarification from like the manufacturer or something here.

Mine NanoVNA-H4

First time I used it i did the charge before use. I was "Told" that when charging the red led will flash, and when fully charged, it will be a constant light. At least that is what I was "Told"

And that's how I have been using it from the first day. If I know I will need it, I will charge it first.

Connect to charge,,,
Light flashing,,,,,,,,,
ok steady light go and use it.

NOW,,? the thought of the light going out,? first question I have is OK what does flashing mean?

and two,, By accident, I connected it to get charged, and something came up and I was not able to do the test, and I forgot all about it being on the charger. Only to discover it like 4 days later with a solid red light on still.

I would think after 4 days of charging it would be done wouldn't you?

On mine, the red LED indicates charging, and it goes out when full.

I am a new owner of an Aursinc NanoVNA-H, HW Version 3.6
Charged it for 4 hours out of the box, but only RED LED solid.
Used it for 90 minutes matching mobile HF antenna; seems to work fine.
Now to charge it after use. Still getting only RED LED solid. (?)
Not sure about this indication or if it is charging.
Any ideas?

Hi
I have always used the Smith's Chart with the standardized values of the

RΩ +/- jXXX impedance. In the NanoVNA H4 the measurement makes it as RΩ +
XnH or RΩ - XpF. My question is how I can convert the inductive/capacitive
reactance of the impedance of NanoVNA to the "j" value standardized in the
Smith Chart.


X = 2*pi*f*L

X = -1/(2*pi*f*C)

If L in nH and f in MHz, then X = 2E-3*pi*f(MHz) * L(nH)

if C in pF and f in MHz, then X = 1E6/(2*pi*f(MHz) * C(pF))
