hugen, Thanks for the additional information. Do you know what generator chip is used for 700 MHz fundamental operation? I agree the noise is higher than I expected for a second generation design, but

4.2 GHz is uint32 limit Vs 700 MHz harmonic frequiency should be 700Mhz 700 - 2100MHz 2100 - 3500MHz 3500 - 4900MHz ....

The edy555 NanoVNA2 still uses a 2.8" display, with harmonics above 700MHz. Use ADC arrays to speed up scanning. At the moment it seems that the noise is still relatively high and the manufacturing

edy555 released a screenshot that appears to be his prototype NanoVNA-2 operating to 4.2 GHz (see attachment). No other details were provided. The s21 noise floor in the attached photo indicates that

I've put the PHSNA User's Guide in a shared folder (see link). I think the groups.io group still accepts members. The moderator is N5IB. The User's Guide wouldn't be of much interest to most nanoVNA

Hi, First - I am new to the nanoVNA and working a little every day to climb the curve. Antique antenna myths and an SWR bridge have defied me for several years since I moved to this location - even

I have a Nano F.? I used it on my Butternut HF9V antenna, a 9 band HF vertical.? It has been up for about 20 years.? Watching the swr and return loss during a spell of high winds showed a lot of

The large letter SWR firmware was a great idea and created by forum member REALD. It can be found on his Github page: https://github.com/reald/NanoVNA However - it's old firmware from Dec 10/19.? If

I didn't know that, probably it is because the project is some years old. If anybody is interested I can send it via personal message. 73 de Ignacio EB4APL -- El software de antivirus Avast ha

Why do you say that? I personally would not buy MFJ, and a RigExpert purchased by my radio club had an out of specification N connector. But I fail to see why your comment is accurate. me neither RF

Of one knows the nanoVNA, one knows that it can simply trace SWR/Impedance, and nothing else. Just a line. For less than 50USD, its not possible to find a more accurate device, even for "antenna

I agree with Ed. I have an early NanoVNA, and a more expensive one by Seeed, the Sark 110, but to do antenna installs and tuning of my antenna matching device I use my YouKits FG-01 as it just gives

Oristo: Regarding: $15 Particle Xenon has bluetooth Be aware that is a discontinued part that Particle is no longer manufacturing.

The MFJ analyzers and the NanoVNA are two different animals. If what you want is measuring SWR, and nothing else, the analyzer is for you. If you ever worked with a VNA, and know the repertoire, you

Im very happy with a recently acquired H4 from Gigaparts and the smaller and older Hugen version. Carl

I want to add to the list please? You want the nanoVNA so you can read the "antenna system" into your computer. Save the results. Then open up a program called SimSmith and analyze your system and

Thanks. ---? Ciao baby, catch you on the flip side?? 73 de W3AB/GEO ??? http://www.w3ab.org You can say "over", you can say "out", you just can't say "over and out".

You might find the MFJ easier to use if all you want to do is check SWR, but if you want more details, you want the NanoVNA.? I own two of them, will probably buy an H4 soon, and will also buy the V2
