How do I load the AA firmware? My friend wants to buy one for his antenna analyser work. Manual says it can be done, but no instructions. In fact where is the code?Sent from my Samsung Galaxy

Yes, emphatically yes. I'm hopeful mime will have arrived by the time I'm home from work today so I'll need a helping hand and a good manual will be invaluable.

I got mine from Ebay, it was a Black one. I found that the sma connectors were only soldered on the center pin, so had to solder the earths. This one had green led's G4XGN

Well ...I bought 2 ...One from Guangyi0016 (has red leds) and one from hugan (has blue leds) ...both look/work/calibrate identical ..shields on both are open ends.. Jim

Now that I’ve received mine and have begun devouring the posts on this site and other info to learn more and enhance the usefulness of this amazing little kit. I was wondering if there would be

I originally ordered mine from Ebay. It was an auction, and I won it for $40. I guess it was too cheap, so the seller claimed it shipped, wasted a month, and refunded my money. It was the non-shielded

I just received mine today. It took 9 days to arrive. It’s the white version that has the SA612A chips and was loaded with the 900mhz 2 trace software. It does not come with cables. Does come with

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

After reading some reviews I have placed an order from seller 'Guangyi0016 Store' at AliExpress. https://www.aliexpress.com/item/33043060569.html?spm=a2g0s.12269583.0.0.1e2963715TXCg7 Hope to get in
