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

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

All the large engineering projects I have worked on have had a "tool freeze" date. Once the software tools for the project have been chosen we update to the latest known good version, and then keep

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

As a 25yr veteran in sustaining engineering, the “should I upgrade?” question always makes me laugh uncontrollably. If you don’t know why you shouldn’t upgrade, the answer is always,

Great thanks.

I created an issue on GitHub regarding your proposal: https://github.com/NanoVNA-Saver/nanovna-saver/issues/517

Hi Victor, Thank you for your update and information. There are different ways to measure CMC performance as there are different 'lumped' component models of a CMC taking account of parasitic elements

Of course you should still upgrade to the latest. You will get bug fixes, performance improvements, and new features. FREE! 73 -Jim NU0C m2walter@... wrote:

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

Hi Jerry, You're absolutely right. It's not all or nothing. A semantically better way to say it is: RF current always favors the path of least impedance. The degree of "favor" is divided between paths

The measure of a "good" antenna is how well it performs. When I lived in a house with a lot bigger yard a few years ago I had a 40 meter vertical full-wave loop antenna (~12 feet high and ~58 feet

You're correct. I was thinking about it and tried it: the NanoVNA does go to 900 MHZ. And all this time I thought that since the default stop freq that it 'boots up with' is 250 Mhz that it was not

Hello Ed, I have not much now to look into this, but this article: https://hal.archives-ouvertes.fr/hal-01886795/document Gives your method (Fig 3b and Fig 7a. So one can measure some aspects of the

Yes, indeed...... The measure of a "good" antenna is not SWR. Of course, a 1:1 in a 50-ohm non-reactive system is essential to keep the transmitter output stage happy, but does not measure how good an

I have an original NanoVNA: it only goes up to 250 MHz. Can I upgrade the firmware and obtain additional functionality? If the firmware can be upgraded which version should I load. Tks. Mark Walter

Thanks.
