Hi Luc, I just downloaded your version 2.02 March 2020 english PDF and there is no difference on slide 25 from the Dec 2019 PDF. It still shows: NODE = highest z or maximum voltage ANTINODE = lowest z

I think that calibrating with the nanoVNA saver is better, because you can divide the frequency span in segments so you can have a lot more that 101 points hence a more precise calibration. Also

I am using nanovna saver(PC) with nanovna-h for my needs. What is the use of calibration menu provided in nanovna-saver?. Calibrating with nanovna-saver is just enough, effective and correct?

That ferrite is before the input though... this seems to be after it.

Perhaps a ferrite core like the EU1KY analyzer? IDK

Hmm... interested to know what's going on with the void in the PCB. Likely to do with the directional bridge, but what? / Gerry

There was still a small error in slide 25 in the English version. The drawing was correct, but in the text I mixed up the meaning of NODE and ANTINODE. Now corrected, without changing the version

There is almost no difference in the amount of commenting between the various nanoVNA branches. You can easily do on github a comparison between branches to find out. But all are fairly easy to

This one looks satisfactory... 1500mAH https://www.ebay.com/itm/112935147215

Yet another "off the beaten path" , and very polite request. Feel free to ignore it. The NanoVNA is "open source" - hence many "dupes" exist. I would be very grateful to hear from some experienced

As long as this topic is being addressed, how about links to suitable products?

This confused me as well at first. I was expecting to see impedance expressed as something like 10 + j240 ohms on the smith chart mode. Actually these are the resistance and reactance values, not real

It was very definitely the cable. After buying a new cable, windows recognised the device automatically, no messing with drivers was needed, and NanoVNA Saver worked first time. Apparently some

this is slightly off topic but the ne602 is prone to overload. I recently built an upconverter and I used one of these that works quite well .ADE-1-24 ADE-1-24+ DOUBLE BALANCED Frequency Mixer RF I

Hi nanovnauser; A couple of more or less encouraging comments for you. Your VNA antenna measurement results indicate the following: 1) You did well... You are using the VNA and interpreting the

Hi Roger, Thanks for the suggestions, I have the attenuator shown in the picture and did wonder if I could use this but was not sure about the calibration procedure. I will try this as well, currently

Also on tindie. Any plans to release a review of the prototype unit that you got?

Battery spec is in the spec doc in this thread -- NanoVNA Wiki: /g/nanovna-users/wiki/home NanoVNA Files: /g/nanovna-users/files Erik, PD0EK

Looks like an interesting way to get on 80 meters which is not something everyone has the airspace to do. If you want to play with it try moving the two whips away from each other with a copper pipe
