I looked at?Aliexpress but saw no one offering a battery. All of the descriptions seemed to be actually the same. Since there seem to be variations among those offered, it is a great help to know

The dates are slightly different when firmware is installed. I used the firmware dated June 11 (20190611). But when I checked the firmware info inside the NanoVNA it said June 12, so that is what I

Spot on Dave, I agree. Addressing this process would provide a nice value added capability. Alan ________________________________ Sent: Wednesday, July 3, 2019 2:57 PM To: nanovna-users Subject: Re:

I just ordered the black unit with cables and battery and you're right, the Gecko unit is slightly inferior. Have you found the source code repository for the June 12 versions of F/W? All I have are

Okay, I get what you are saying now. That problem should I guess be resolvable in the firmware, although it will take a very careful look at the firmware to see how to resolve it. But the problem

Hi Larry, You did a good job with the command list. No problems found! Yes, there are several versions of the NanoVNA firmware. I have found that the June 12 version is the best. It fixes the

Oh I use banggood all the time. I am more of "when is it coming" does anyone know. I ordered it on may 26th.... But its a waiting game i guess. Just being impatient :P Definitely need to get a batter

Banggood, Gearbest, Tomtop and a few others are like Aliexpress and eBay (buy it now mode) - they are an umbrella of many vendors that take a % of sales. You shouldn't have a problem - I've bought

I pre-ordered my Nano-VNA from

I guess to make the point clear, 3.5 mm SMA standards DO NOT APPEAR as IDEAL SHORT, OPEN on the chart. The fact that they DO on the nanoVNA SAYS IN ITSELF... There is an issue!

I am quite familiar with the error. Please read my post carefully. I point this measurement observation out as this is a STRONG HINT that something is NOT correct! In any case, I measured their

I'm afraid to say you are stepping into the error many people make. They first calibrate with a set of standards, then see those standards look perfect on the Smith Chart. I have hayfever at the

I should add, that after a calibration with their standards, the resulting short, open and load are PERFECTLY located on the chart. Really! Wow, I have to pray that a set of APC-7 or my sophisticated

Hello David, I mentioned in a much earlier post, I have no idea what is in the firmware definition for the standards supplied with the nanoVNA. In addition, based on the physical description of the

And with battery upgrade. My unit doesn't have a built in battery, so I found one, for now works... but pretend to update the connections and the battery itself, this one is a "little" big for the

What exactly do you mean by that? Are you saying that the firmware has the ability to allow one to adjust the delay of the calibration standards? If so that’s good news. Just being able to enter a

Yes, calibration data can only be modified with electrical delay. For better accuracy, I customized the shortest and most accurate calibrations kits possible. Naturally, the accuracy of professional

Hi George, I scarfed the commands by going through main.c (and a few posts here) and there is some ambiguity on how to format a few of them as well as how executing some might affect others. If you
