Again, SimSmith allows for SWR circles (among many additional options). It can be downloaded at: http://www.ae6ty.com/Smith_Charts.html An excellent tutorial can be accessed at the following:

Martin, the NanoVNA-App software by One Of Eleven supports display of the admittance and reactance Smith Charts side by side. Is that what you are asking? 73 Martin 9A2JK

I had issues with the DfuSe recognizing the Nano VNA, be sure to install the driver!!!! This step was glossed over in Alan’s video which I followed as well but it is mentioned in PDF instructions

I attach the lanyard by removing the screw from at least one standoff (the metal standoffs keep the NanoVNA circuit boards separated) so that there is enough room to slip the lanyard material through

Sometimes when using USB-3 ports it can behave weirdly. [email protected]> wrote:

John I also updated my H4's firmware recently. I have no expertise in computers or programming, but since I had an H4 and a Win 10 pc and have a high regard for Alan's series of videos - thank you

What about 4" NanoVNA V2 Plus4? The web site remains unchanged since Oct. 16 (a month...). Any news? The Waitlist is active? 73, Martin, OK1RR

A bunch of samples are acquired and then multiplied by sin/cos at a single frequency, and then summed. Essentially it's the same as a single bin of a Discrete Fourier Transform. Since there's no

Stephen, I've always assumed that the filtering out of the fundamental or desired harmonic response was performed using a "classic" tapped delay-line digital filter. Assuming that noise is white noise

John, I can confirm what Christian wrote. I updated the fw on my -H4 a few days ago. To enter DFU mode, hold down the jog wheel before switching on; switch on; release jog wheel; the screen remains

Hi Arie, Agreed. I think I've missed the window of opportunity to ask for stuff like this, as the firmware and software is now relatively stable and any updates and enhancements tend to be 'few and

I've suggested this to the developper of nanoSAVER about one year ago. It became an item on his? to do list, but was never done. Other priorities. New developpers never picked this up but gave

Hi Alan, Yes that was my requirement. I was working my way though one of Owen Duffy's recent blog posts https://owenduffy.net/blog/?p=19276#more-19276 I agree with his comment that having the

You may try NanoVNA-App by OneOfEleven to upload the firmware. Download link: https://github.com/OneOfEleven/NanoVNA-H/ Open Release folder and download the latest version. No need to install. Just

May I ask a possibly stupid question? I understand high-end professional vnas have a real bandwidth filter. Our nanovnas have a bandwdth setting (on some firmwares -not V2 though), but is this by fft,

Stimulus - allow set sweep frequency range my set this values manually Marker-Operations allow also set it, but from current marker data, example you have range 100M to 200M and current marker stay on

Hello John, some remarks: - You have the NanoVNA H4 model with 4" screen (which you probably know), so be sure to use a firmware built for the H4 while upgrading. - The H4 can be put into DFU mode by

Is there a difference between: *-Marker -Operations -Start -Stop -Center -Span* -EDelay And *-Stimulus -Start -Stop -Center -Span* -CW Freq -Pause Sweep Does the Stimulus/Bandwidth and Calibrate/Power

Hi Ross! Thanks for the FUN! It really is not that bad. However, I think what Martin would like is the ability to flip the standard chart off, turn on its admittance form and then the ability to
