Hi, I'm facing the same issue with my new NanoVNA V2 and NanoVNA Saver version V0.3.10 under Win64. In 9 out of 10 calibration attempts I get the following error message: “two of short, open and

So, after years of almost constant use (I got nanovna 2 the moment I could) I fried channel 0 because of my stupidity :-( I connected it to an antenna switch that had a short that send +12V DC from

If you wrap coax tightly around an object of known diameter ie: a cable drum add 1 diameter of cable diameter (which then gives diameter of centre conductor) x pi x n loops you will have a far more

Any ides why the win 8 driver does not work on the windows 10 , i tried 64 bit and still no luck . I am trying to get to the dfu mode , and the driver in the device manager is not found. do we have

Very nice!

I made my own case out of a regular old $10 Plano case, just cut a few of the separators out with a knife, and then put in as made as the adjustable separator thingy's in you wish to store your

It seems to work. First made a 1/2-1/4 lambda matcher. It is now too dark to go on the roof, but will test it tomorrow.

Thanks Larry, that wasn't on the copy of the Structure Map I have but is right there in the expert settings menu. 73, Rudy

It depends on the version of firmware you have.You can set the date several ways:1. with DiSlord's ver 1.0 FW, it's in the expert menu.2. If you connect it to a PC, you can ????a: use Nanovna-App

How do I set the date and time on an H4? Rudy N6LF

Hi Karel, First measure the Velocity Factor of the two used cables, or just take them from the catalog. Then, knowing that, cut the 1/12 lambda's. The length is not super critical on HF . (that's

Setting to 1 the velocity factor would tell how much longer the cable is from the real lenght. That is to say the velocity factor. Is this correct? Luis Ticona

I think that setting velocity factor to 1 would give you direct electrical length readout (rather than physical length, which incorporates velocity factor). So OPs technique would work.? Say you want

NO. The Vp is the velocity of propagation within the coaxial cable. It is slower than free space due to the loading of the dielectric material between the inner cylindrical conductor and the inside

I would like to make the 1/12 matcher for 75/50 ohms. Perhaps a stupid question, but would setting the velocity factor to 1 give me the electical length of the coax? So i just have to snip off pieces

Problem solved by using a different card! Thanks

hi Jim, I noticed it, temperature sensitive. I have a Tabor Electronic brand AWG. According to the manual, the WX2182C model uses 14-bit DAC to generate arbitrary waveforms signals. Last question: Why

Dave, you are, of course, right. the cheaper sets of calibration standards can be anything between pathetic to pretty good, even from the same manufacturer. The set from Array Solutions that John

I tested it on Linux and it works fine. Instructions have been updated at https://github.com/brucemack/nanovna-controller. 73s, Bruce KC1FSZ
