Hi Andy - The W0QE paper indicates that, seemingly because of errors introduced by parabolic curve fitting in AIM4170 software, calibrating with higher impedance yielded results that he liked better.

I am using Linux Mint Tina and it works well.

Hi Kurt - Thanks as always for your expertise and patience for explaining VNA best practices! This second paper motivates mastering T adapter techniques, particularly for low impedances.

I am looking for help to try and fix this problem, My Linux computer complaint is : Could not load the Qt platform plugin "xcb" in "" even though it was found. Indications are this is a library

If you can lay your hands on some of the old General Radio (GR) connectors, they would work well. Finding them will be the challenge. Dave - W?LEV

Hi Oristo It is a difficult task to measure highZ components based on two restrictions. For the first the DUT used to test the VNA test set up is it really a HighZ with flat response over a large

This discussion answers many "who is on first" questions. Some of them I had posted on my first post and received some answers too. I have been reading the mail ever since that first post and have

no, it doesn't work because it requires Android 7+ -- *73, Lucio I0LYL Rome, Italy*

I have resisted posting anything for the last day or two, since I want to re-evaluate some of my own tests and thoughts. But reading the link above, am I to understand that it's worth trying to

I insert a small USB hub: https://www.amazon.com/gp/product/B07SZTHPPR so not direct USB-C to USB-C. That hub is not ideal, because it does not recharge the Android host while it runs NanoVNA WebApp

I have a VNA that I am working to get sold in kit/assembled form that can measure 10000+ ohms in the HF in reflection, and can measure 1000+ ohms up to 600 MHz. I will admit, however, measuring high

For example, if you're transmitting at 3650 kHz and your transmitter has 90W emission at 3650 and 10W at 7300 kHz, your VSWR meter will show you average between 90W at 3650 kHz and 10W at 7300 kHz.

if your transmitter has high distortions and out-of-band emission, you will get different VSWR with VSWR meter. Because VSWR meter shows VSWR for all frequencies in the signal. While NanoVNA shows

the same, all have 128 kB flash

Hi Herb My test chamber is just made of parts from the junk box. What you can see is the reverse side of the lid. It has a milled groove along the circumference with same diameter as the inner

With so many vendors selling NanoVNA - does any of them specify the flash size - hence actual processor used ? Or are they all the same ?
