Hello Goup Old Ham here , but have never played with DIY antennas before , and have never had a HF Station. I have just gotten my first HF Ham station (FT-991A) , as i have "some" room in the

Yes, the TinySA is a far better tool for your proposed application. However, the NANOVNA can be used to measure the isolation between two antennas. Use it in a 2-terminal transmission measurement

It should work, though I would terminate the Ch0 port with the 50ohm cap. A better tool is the TinySA. It is about $60 in the US. TinySA.org

Hello.? Can anyone tell me if it's possible to use a nanoVNA such that it emits no signal and only operates as a receiver?? I want to try to detect and measure what is being emitted by an emitting

I am sure you will find this wonderful guide to also be very helpful, assuming you are able to translate your topics of interest into your favorite language.

Sorry, my english is not good. I need software to cinfig the nano vna. Thank you.

Thanks Stan for this feedback. Anyfeedback is very welcome. I put click-on ferrites (25mm long) on port1, port2 and USB cables, they have (in my setup) no significant effect on the measured S21 (or

Victor, I notice that in these examples you are using the nanoVNA with the saver software, connected to a computer via USB cable. When I do a similar setup, I note that the USB cable to the computer

Hi Vaclav, Please type “P3 uart” into the Search box in the upper right to help to identify this board level change. Larry AC9OX

I forgot to add that the NanoVNA measured Impedance (based on the S21 (or S11) 2port series through): [image: afbeelding.png] matches quite nicely the theoretical simulation of a choke:

Many years ago I made a BIG mistake by signing up with my real name. I get unwanted , unsolicited e-mail addressed to that mail box. I am opinionated and I do not pussy foot around issue , I tell how

Could somebody just confirm that I am on the right track ? I do not see "P3" - UART connector on my hardware. https://github.com/ttrftech/NanoVNA/blob/master/doc/nanovna-sch.pdf PS To the person who

Thanks Rich, your spreadsheet also helped me to spur on some of my work. Thanks for sharing! All the best, Victor Op za 11 jun. 2022 om 21:41 schreef Rich NE1EE <TheDustyKey@...

Thanks Roger and Owen, Remember that the S11 formula from https://xdevs.com/doc/HP/pub/5988-0728EN.pdf and NanoVNA Saver (and my own Excel spreadsheets) already takes away the 50ohm (Zload) of port 2.

Thanks for the comments to spur me on...I earlier felt that I had better clean up the spreadsheet just to avoid more confusion, but never took the time. Glad that it's turned out to be of some use.

Here is one of theS11/S21 test jigs I tried. It could use improvement but I don't have the time right now to continue with this project. Roger

Hi Vaclav Sal, I just went to “FB Nano VBA and Tiny SA” and saw the messages that you had previously posted regarding your issues. I believe that your choice to use the alias “Anne Ranch” on

Victor, Let me preface my comments by saying that I have built several test jigs for measuring impedance using the S21 series method and tried several ways to compensate for errors. None have been
