Are you running the Clearconfig command through the serial console after pushing new fw to the device? There are numerous posts about clearing out old cal data when upgrading.? On Sun., 31 Jan. 2021

Try re-installing the older 0.4.5-4 version again, and re-run and see if it goes back to the old #'s.... That would help rule in/out the new version has an issue. -- Regards, Chris K2STP

I agree! Kudos and thanks to Barry for this useful discussion of antennas. My proposition: by the physical principle of conservation of energy can we say that the problem is to get energy out of the

Excellent, Barry! This is the sort of thing the younger crowd eats up. But, I'm an old fossil and I think I got 100%. Good work. I always ask the question: "Does an antenna need to be resonant to

Hello everyone, i tried to install nanovna-saver on ubuntu 20.04 I can't finish the installation Pyton 3.7 does not uninstall because there is version 3.9 ..... I don't know exactly how to bypass the

I was curious, because in general, the tests do not require memorizing of specific numbers (except for a few regulatory questions). A quick "grep" of the question pools says that "468" does not appear

Isn't this getting to be more like Litz wire? Mel, K6KBE

As I taught Zoom sessions on the Nano VNA, I realized that there are many misconceptions about antennas, feed lines, and impedance and SWR. So here is a True/False set of 20 questions to look over. If

Dave, That's when you try to use the same thick wire. You can make a pretty good 50? balanced line by twisting together 4 relatively thin wires with teflon insulation, and interconnecting the

Progress requires an appreciation of diversity over homogeneity. At least that's what we're told, ad naseum (oops, sorry for the Latin in an English-speaking group!). -- John AE5X

Nano VNA slide show .... comments on comments Thank you all for the comments..... feet vs. meters. I had no idea this was going to stir the nest. Not a big deal, but for those of us taking American

I downloaded and installed the *45 software for my H4 and the readings are all over the place over 300MHz now, so will be interesting to see how this thread progresses. The added features are

So I just downloaded and installed the latest software for the NanoVNA-H, version 1.0.45. I upgraded from 0.4.5-4 which was released on January 18th. I have a dummy load that I tested it on, and the

It's surprisingly easy when you do it on one core but yes, you sacrifice the available space and 160 is tricky, unless you are using a huge core.

True, but then I don't get enough turns on the toroids for 160-meters. And the thought of matching two CMCs to parallel, each with 100-ohm lines on them, does not sound trivial, but could be done.

Progress requires sacrifice (in this case a tiny mental one) and you should consider that this is not a USA exclusive group.

I don't see the point in getting the F variety when one can get the H4 with its open source firmware.

Pretty easy to get 50Ω line if you parallel 2 100Ω ones.

We did, but not the households, cooks, garage mechanics, money shufflers, civil engineers, and........... Now all our MIL-SPECS and MIL-STANDARDS contain tables at the end as an Appendix that offer
