If you are going to be doing outdoor work, I strongly recommend the H4 with it's 4" screen. It is extremely difficult to distinguish between a slash zero and an 8 in bright light. Also, the H4 shows

if not going above 900 mhz , get the nano h4, get from randl electronics, it will NOT be a clone.

Make certain that you are buying a genuine nanoVNA and not a knockoff. The list of approved vendors can be found here... https://nanovna.com/?page_id=121 NanoVNA.com is the place to go to about your

I bought a NanoVNA-H v3.6 recently and I am happy with it. I use it mainly for antenna tuning. Here is my little 'NanoVNA for Antenna Tuning: A Beginner's Guide': https://youtu.be/qb38VI-9tV0 Other

Looking at the number of different versions available on Amazon, I'm confused. Although not an abnormal state for me, I try to keep it to a minimum. Can the group make some recommendations for a

Reading the sticker at the backside of two NanoVNa units I see a difference. One is HW version 4.2 and the other is HW 4.3_MS I have understood that the additional _MS refers to the MS5351M (message

Hi Peter. I limited the number of traces to two because that's the minimum number that allows comparison for optimization. I didn't think about your application, which is more documentation. To do

Hello Brian, I've been following the evolution of your Smith chart plotting and am pleased you've been able to add the feature to your plotting package. As a user of Smith charts in both RF design and

Correct Brian. It is a clever engineering concatenation of the two descriptions for Y and Z COMBINED... Good stuff!

Alan, when I first read this I thought it was a typo for admittance. I learned this morning that it means impedance or admittance. I have been using Y + Z for lack of a better term. The next version

Hi Hugen Thanks Pse did you mean slightly better below 100Khz or below 100Mhz ? 73s Nizar

Thank you for your information. Kees, PE0CWK Op 30-4-2025 om 04:05 schreef Hugen via groups.io:

Hello, after NXP discontinued the SA602A we designed a compatible chip for the continued production of the NanoVNA. This chip has a slightly lower noise figure, but also a slightly lower IIP3. I

If my memory serves me correctly the major difference between the ne and se version had to do with the temperature range they were spec'd over. wrote:

I think that having two grid colors is pretty important to help visually distinguish between the impedance and admittance grids. Traditionally impedance has been plotted in red and admittance in green

That's what I was hoping, Don. It was so easy to implement! I think I'm going to leave two grid colors for another time. I could do two gray intensities without much trouble, but I don't think that
