I have made some progress. I wanted to be able to extract the FW from my device for backup. I can't seem to find FW that matches mine online. This

Seconded. I bought mine there, along with two sets of adapters. No complaints... WD3WTF -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of

Yeah, I do it by a screen cap of the window (attached, MacOS-X). The calibration files do have the frequency range: # Calibration data for NanoVNA-Saver ! SOL Calibration ! 27-30Mhz 101 Points # Hz

My original post (way back) was about how I used my Nano VNA to help make my 140 ft closed loop tune up better on 40m. It was a simple post about the instrument, the Nano VNA. I did not intend that

P.S. - I've used 2 different NanoVNAs on the loop and random wire antenna projects, an 'early' clone of the original 2.8 inch, and a NanoVNA-F. Both have been very helpful, and I use them a lot. --

I have put up 3 long wire loops around my front yard, over the years. The first was made from several pieces of leftover pieces of 14 or 16 gauge THHN stranded wire, patched together with different

Thank you very much, Roger. Best regards and have a nice day, Stefan On Mon, Aug 14, 2023 at 04:44 AM, Stefan Dimitrov wrote: You need to use Device manager to see if a COM port is active for your

And of course, the software should remember where it was when it was stopped, so that it would start from there next time.

After some use I noticed a couple things which could be better in NanoVNASaver.win.x64 software. First, I posted this also to /g/NanoVNAV2 but after a couple of days it has not

Maybe because nobody bothered to try? <grin> Sometimes, I find the derivative of unwrapped phase (group delay) more useful, too.

I have a 40m 144' horizontal loop also at about 20'. It is a right triangle. The pointy end is due east and is a little lower. I feed it with BalunDesigns 1:1 balun and then about 55 feet of 450-ohm

I like my SAA-2N, it is the one I generally reach for in the shack. It works fine with external programs or standalone, updates work fine, and I like the type N connectors, as my shack is mostly type

I don't see much mention of the SAA-2N v2.2 Does everyone recommend the H4 over the SAA-2N? The price difference is not of concern I am more concerned about functionality and support. Brian W1BKW

What ever you buy, I'd recommend using its "official shop". There are links on the homepage.

I would strongly recommend buying from R&L Electronics. You won't get a clone from them!! Here is the link to them for the NANOVNA-H4:

Nanovna-H4 is a great basic vna, if you don't need multiple GHz frequencies. It runs the latest firmware and is actively supported. And you should be able to get one for less than $100

Hi Jim. Thanks for the reply. The answer is simple. Convenient! A pair of trees are there, about 100 feet apart and between them, nothing. No balun used. The ends of the dipole are away from each tree

Have you checked the homepage(s). Like https://nanorfe.com/ and https://nanorfe.com/nanovna-versions.html I can recommend V2 Plus4 Pro V2.4, it costs 299$ plus 18650 battery. But today I would try to

Hello Alan Did you start with some ideal calculated length for 7.05 MHz, set the dipole at 7 feet high and then trim the length for best return loss? Or perhaps put up precut wire for a higher
