Maybe it was the selling blaming Aliexpress for the surcharge then.? Whatever.

Have not tried with the VNA, but have done with a SNA and RLB. Just need a pickup coil. Here is some info on my blog about that method I used,

I always thought Grid Dip meters were cool, but it seems a VNA can be used as a Grid Dip meter. Has anyone done this? Does the unit need to be calibrated in a special way? Is the output loop critical

I purchased from Guangyi0016 as well. Ordered it on July 26, arrived today. It took about a week to ship, but otherwise OK. The shields are open on the ends, but I'm sure it's better than the

Can someone explain the values in the data array? Thanks Joe W3JDR

The NanoVNA specification for frequency accuracy is +- 0.5 Parts Per Million. At 30 MHz it would still be in spec if the frequency error was as high as 15 Hz. My unit measures 220 Hz low at 900 MHz

Hello all- I ordered a NanoVNA on eBay and received a black version in a plastic case with mixer shielding and accessories (cables and calibration kit). Mine was like Herman's; it would boot when

I have done some Measurements on my NanoVNA. Maybe the tolerances are higher at other NanoVNA but i am very surprised of my Results. Is there anyone out wo can confirm my work? The Frequencies are

It's probably worth stating that you are not ordering from Aliexpress. Aliexpress is a marketplace, in much the same way as eBay or Amazon Marketplace. They provide a platform, and an escrow system to

No, not true, and there’s a lot more going on than just tariffs. But this is definitely not the place for this discussion. There will be no further comments from me on the subject. Peter

An ignorant comment. “Cheeto’s” tariffs have been completely absorbed with the Chinese government’s devaluation of the yuan. Anyone who accepts an increase in price “because of the

So many will feel the effects of a trade war. Unfortunate how so many people will be negatively impacted. I hope it gets resolved soon but am not very hopeful. It’s a real question whether my

Not to mention Cheeto's Tariffs on Chinese goods.

Aliexpress DOES take paypal, however there is a small service charge (~$2) for this. I just ordered from one from them.
