Here is another fixture idea. The connectors are Pomona BNC female #2451 and the contacts are a Phoenix Contact #1190363. In the photos the "short" is installed. You can see that there is an easy

Because noise is pickup by the braid of your coax.

Hi Barry, Did you tried to place chokes at the transceiver side and one at the feedpoint side ? That would normally solve your noise level issue. Best 73, Ben

Hi John Gord Did SAA2N & LiteVNA64 has the same firmware of NanoVna-H4 ? And did they work as good as -H4 on 10Khz-300Mhz band ? 73's Nizar

If you are in the US, R and L Electronics (randl.com) has the 3GHz NanoVNA SAA2N at $110 and the 6GHz LiteVNA64 at $160. I have both, and have been very happy with R and L as a supplier. --John

A natural evolution. As a related comment, using Amazon as a relative comparison, the H4 versions are U.S. $60-$90 while the V2 versions (with N connectors or SMA) run $250-$360.

My understanding is that the answer was the clock chips are the reason for the variants. So it is important to discover which version of the hardware a person has to install the right firmware. Thus

Any 0805 resistor will do, they are all "non inductive". Just search for SMD resistors. You usually get a couple with that board kit. <gervail.antoine@...> wrote:

Hello group, Can I ask what all this has to do with the ORIGINAL QUESTION?? "Why so many different names for the firmware .DFU files?" I love how so many people seem to enjoy HIGHJACKING a

Yes non-inductive is very important. https://www.aliexpress.com/w/wholesale-smd-resistor-book.html?spm=a2g0o.best.search.0 One of these will suffice

Sorry, Dragan.. querty keyboard..

Excatly when I just ordered Draganm thanks for the tip about the other "pins". Do you have any aliexpress link where I can find the SMD resistors ? is the non-inductive part really important under

Good to know about the limitations in the VHF UHF domain. I'll keep that in mind when testing for now I'll mostly stay in the HF domain trying to analyse my "future" EFHW antenna. I guess as you said

Those are good up to ~100MHz, really useful for all sorts of small components. Don't overpay for it, these usually go for ~$3: https://s.click.aliexpress.com/e/_DB7YAkD A really useful addition when

You don't need "precision" resistors. "Close enough" like 47 or 51-ohms for a 50-ohm non-inductive resistor. The most importance consideration is that it's non-inductive. Dave -

Gervail: Thanks for the tip*. There really is NO definitive, easy-to-understand users' manual for the NanoVNA-H4. There are many YouTube sites that you can find. I've looked at many of them as I

Really interesting document, I'll definitely try to reproduce the steps and I will be really happy if I can make it work. And also really nice little fixture. I did a bit of digging and found this
