Thank you Tripp! I have the 2.8inch version and will try to upgrade. Will there be any changes to the user interface or is it the same as I'm using now? LA1BN Bjorn

Barry, Some versions of the Smith chart include a scaled "ruler" calibrated in RL, SWR, and reflection coefficient. The ruler can be either cut out and used directly to measure distance from the chart

Oops I messed up the 0.9 reflection coefficient with SWR close to 20 It looked too small when I made this.... but I can blame the circle being too small on my sloppy use of the mouse with Paint I also

It seems to me that a logical way of looking at the Reflection Coefficient or the SWR on a Smith Chart is to plot a circle with the perimeter representing all of the impedances that have a given

You have to use the DiSlord firmware to get screenshots which is here: /g/nanovna-users/files/Dislord%27s%20Nanovna%20-H%20Firmware/NanoVNA%20v1.0.39.rar if you have the 2.8 inch

Hi and tnx for a really helpful piece of software!. It works fb with my TinySA but stops half way getting the dump from my NanoVNA. Ver.0.4.5-1-gfbbceca what can I do to make it work? 73 Bjorn

I have seen a lot of the same subject "bricked':. I am passing this on a a possible cause. I my case I upgraded fine with two computers. Then I purchased a new Laptop with only USB3 Ports. It goes to

Thank you for sharing this very good idea ! 73 QRO, Rudi, HB9ARI

I stumbled across this very helpful page about how to avoid dropping the NanoVNA while up on a tower. http://www.ok1rr.com/index.php/technical-topics/95-drop-proof-antenna-analyzer There are _many_

Thank you for that. I have a push-button on the right hand side of the nanoVNA that enabled DFU. Hold the button and toggle the power switch to "ON" and a blank gray-ish screen appears. Plug in the

Curiosity, Does the Nano VNA have enough free program memory to implement SCPI? I was wondering about this implementation https://github.com/j123b567/scpi-parser

great! I know, here is not a correctly place to share it, but, do you have idea how to save in my PC snp (s2p) file from a PNA ? Thanks for. Em ter., 10 de nov. de 2020 às 19:49, Jim Lux

Hello Nano VNA folks Again, thank you for the feedback. Yes, this is what I asked for. I try to be careful with language, but the slide on antenna "efficiency" was just sloppy. My main point of

Hi Peter, I had a working NanoVNA that I wanted to update, but it also didn't work with DfuSE due to only STM32 BOOTLOADER showing up in the Win10 device manager. The STM32CubeProgrammer indeed did

That was 19 words. :)

Joe, You have a very old release of firmware. Read up on how to place your unit into dfu mode by shorting the boot 0 pins and then flash the latest firmware.You'll need to install the dfu utility or

Hi Joe, Welcome to nanoVNA users. Indeed: he who dares wins. For someone who has a problem and doesn’t know the solution, it’s hard to articulate what their problem is. The interviewer knows best

Nothing ventured, nothing gained. I did a blind firmware update to get to 0.8.0 and now all is right with the nanoVNA. I have a config button. The risk was worth the reward and I appreciate those
