Here is another application for nanoVNA. I own a Narda 3060-20 directional coupler that I have not been able to find directivity information on. The coupler has a 10-200 MHz frequency range and a -20

DOCX was converted to markdown using pandoc, then hacked and posted to GitHub: https://github.com/oristopo/nanoTAPR/tree/nanoVNA This markdown has yet to incorporate nanoVNA content; pull requests are

qrp.ddc Thanks for your reply. I agree it would be very detrimental to the our measurements to put a diode in place that has 10-15 pF of capacitance. I would never recommend that. Apparently you did

0.0.10a is Rune's pre-release at https://github.com/mihtjel/nanovna-saver. This is the location for his latest commits prior to final release as executable.

hwalker, Where do you find NanoVNA Saver 0.0.10a.exe ? I went here: https://github.com/mihtjel/nanovna-saver/releases and see 0.0.10 but not 0.0.10a. Would love to have the whole screen fit in my

Maurizio, Rune's latest commit 0.0.0a adds an averaging option. Check it out and let him know what you think.

Hi , I found some info about the smoothing and average on Keysight network analyzer at this link : https://www.keysight.com/main/editorial.jspx?cc=IT&lc=ita&ckey=606542&nid=-11143.0.00&id=606542 Best

Hello tinhead, Thank you very much about the hint with the terminal, to ask about the nanoVNA version. I did not know that. As you can see in the attached screenshot, the "version" command answer is

Thanks Larry I will pull it apart and have a look. regardless if the replacement switch is sent I will replace the switch with SMT switches as in your mod. Andy "thats buying from China" As the saying

Rune, I just checked out your Latest commit, 0.0.10a and loving the fact that on my 1366x768 display I can see the whole screen without needing scrollbars. All the charts size very nicely at font size

Use the zero span option. That way the display only reports your "channel" I think that would work. 73 de Andy

Rune, Thanks for all of your work on this. I know from personal experience the effort and dedication that something like this requires. When I bought my NanoVNA, I had no idea that I was "surfing" the

Warren, Thanks for the kudos, I always try to figure out a way to find new uses for existing things, Sadly, these ideas usually pop in when my mind is idling right before bedtime, and then I'm up for

Thanks for all the comments and suggestions. For current batch of the tests, my reference antenna has been a normal car 2m/440 mag mount car antenna on top of a metal file cabinet with about 2m of

Hi Rune, Attached is the calibration File. Thanks Again. Jim K. K8SLC

Hi all, just for your records, attached is a VNWA plot of the NanoVNA RX input impedance. 73, Norbert, DG1KPN

if nothing there in your firmware (no info in boot logo or no version menu) try simply "version" or "info" via serial terminal. But honstly, who cares? just download the latest version and enjoy

Hello, Allow us, please, to we report that in order to be adequately prepared to estimate the uncertainty in NanoVNA measurements using complex differential error regions and real differential error

The FFT assumes that you have a perfect fit of the (co)sinus in the sample range. At higher frequencies the 5kHz start to deviate so the samples may no longer fit perfectly in the fft and you may get

Ok, looked at the source code and it seems that 2mA is used in fundamental mode and 8mA for harmonic (above 300MHz). This should make a big difference in Si5351 output impedance, isn't it? The
