Re: New FreeRTOS-based nanoVNA 4.3" 800x480 LCD on Aliexpress
You might like to look at the test board kit from SDR-kits. https://www.sdr-kits.net/DG8SAQ-VNWA-Testboard-kit There¡¯s a lot more parts in it, and I suspect that you would learn much mote. That demo

Re: Place to buy
Just a note on my experiences with buying the nanoVNA. I bought my first nanoVNA on amazon.com on August 11 as a KKMoon product with the seller shown as WSS-store. After ordering it I noticed that I

New to NanoVNA with questions
I just received my NanoVNA and downloaded NanoVNASharp and started playing. As a background, I have read quite a bit about antenna tuning/evaluation but have ZERO practical experience, so despite my
Re: Early app for the NanoVNA
Excellent, Rudi. I'm not a big fan of the lines myself - they can easily obscure the fact that you've using a linear interpolation which could be very inaccurate. So I prefer to up the sweep count

Re: Early app for the NanoVNA
Hello Rune, I just tested your version 0.007 under MacOS Mojave 10.14.6. The serial port was found correct. The lines between the points are looking good to me. 73, Rudi DL5FA

Re: Early app for the NanoVNA
Hi Tom, thanks for the suggestion. I think that looks very workable. Sadly it's only been minutes since I released v0.0.7, which still has the "Reactance" label - but it won't be long before 0.0.8 (or

Re: Early app for the NanoVNA
Hi Rune, With regards to the "Reactance" label I wonder if it would be beneficial to provide both C and L equivalent values for the measured X. Considering the 126.1 MHz example of Xc = 358 your might

Re: nanovna-saver 0.0.7 crashing on Macos now
Looks really great! 2 nits to pick: 1. It would be convenient if the marker summaries would included the frequency 2. It would be nice to scale the overall screen as it is too large to fit on my

Re: Noise
FWIW I measured one of the 60 dB.com bridges at a directivity of ~40 dB using TDR with a Tek 11801 & 20 GHz SD-24. That was the ratio of the step on the incident output vs the pulse on the reflected

Re: nanovna-saver 0.0.7 crashing on Macos now
Hi Mario, if you click "display settings", you can change one of the 4 plots (or add up to two more), where one of the options is S11 VSWR. That should be the one you want? New feature since 0.0.4 ;-)

Re: nanovna-saver 0.0.7 crashing on Macos now
Yes, that fixed it - my report that 0.0.4 was doing it too was a PEBCAC error - I was launching that one from a script that now points to the new one... Great work. My only complaint about the general

Re: NanoVNA selector switch issues?
Here is another person with the same issue. http://bobdavis321.blogspot.com/2019/08/nanovna-vector-network-analyzer-50khz.html Is it a hardware or a software issue? My analyzer doesn't seem quite as

Erik, Perhaps I misunderstood. From this, sounded like you are thinking of removing the 390/50 loads: Regarding termination, I was thinking the 50 ohm resistors terminate whatever is coming from the

On further testing: Now 0.0.4 is crashing the same way. This must be something the pip command did when I ran it to install 0.07. mpv

Re: nanovna-saver 0.0.7 crashing on Macos now
Wow. If you try running from a terminal window, you should get any error messages from the application on there. But I don't know if that's what you already did, and this was the entire error? The
