Re: Common ground and 2-port measuring
Hello Ed, I postpone my experiments until I can build these transformers needed to do a proper(?) DM measurement (as described in the earlier article, Fig. 16b). A month ago I ordered some small

Re: Should I upgrade firmware, and if so which version to use?
Apples and oranges. The Nano is a small dedicated purpose device with a tight team of very smart developers. Windows is a bloated Swiss Army knife *operating system* software by committee. Hardly a

Re: Ubuntu PPA or .deb installation
Not sure this addresses your problem, but I do not see the need for a package (.deb or otherwise) as NanoVNA-Saver comes as a binary for Linux, Mac and Windows, no need to install anything. This

Re: Should I upgrade firmware, and if so which version to use?
I have not found any upgrade for the NanoVNA that required any "learning curve" besides what was needed initially to learn the instrument. Operation has been as it always was. Some of the improvements

Re: Should I upgrade firmware, and if so which version to use?
sometimes you get a device that has a very old fw in it (seller had it for a year before selling) ... with maybe slow scan speed and lower points per scan (and that means lower resolution!)... and

Re: Should I upgrade firmware, and if so which version to use?
Agreed, but I don't know what it is, and perhaps shouldn't blame Windows. However, once I have a setting that works, an update shouldn't change it. - Michael

Re: Should I upgrade firmware, and if so which version to use?
David, I agree with you: my NanoVNA with original firmware does exactly what I want I to do. Sure there may be useful new features in the updates, but one thing that really puts me off is that a major

Somehow you all missed my point a few days ago¡.. much of the upgrades in firmware are beyond the pay grade of many of the initial users. Until one gets used to using the nano (or your handheld or

Re: Should I upgrade firmware, and if so which version to use?
But if your wife wants to "upgrade" her shoes do you tell her no? :D The bottom line with upgrades is stuff works better. Who doesn't want that? The developers are very quick to fix bugs so you can be

Re: Should I upgrade firmware, and if so which version to use?
I have a NanoVNA H4. One thing I like about recent firmware updates is that, when you save a calibrated frequency range in the memory, it then actually displays the frequency range that is stored.

"Can I upgrade the firmware and obtain additional functionality?" Yes. You didn't say how old your NanoVNA is, or its firmware version - but, if you carefully make note of its current version, find,

Right. The question should be "am I missing something I want to use right now or am I using something that has a bug and should be repaired right now." If you don't know what you're missing and all

Re: Common ground and 2-port measuring
A clasic way to explain this was to connect 2 ports with coax, connect the coax shields on 2 ports with a short piece of wire and try to measure the current in the wire but I like this graphic, it is
