Although I got my NanoVNA back in ?February? I have not taken time to work with it much. I did purchase a bag with ?10? PCB edge mount SMA connectors and after yesterday’s traffic about “NanoVna

Lee, When accessing web links, if you find a dead link, go up one level to see if anything has changed. If you look at http://gunthard-kraus.de/fertig_NanoVNA/ You will see there is a German and

Update. Still no luck finding the article. The way back machine had some of his information but not on the NanoVNA-Saver. https://web.archive.org/web/20190215164504/http://www.gunthard-kraus.de/

I am trying to come up to speed with my NanoVNA and the NanoVNA Saver software on my own (not asking every single question on the forum). I have installed NanoVNA-Saver and connected to my instrument

Just thought I'd let the group know that r&l electronics has the h4s back in stock for $59.95. f o b Hamilton Ohio so shipping will be fast. I have no interest other than being a satisfied customer of

hi, then I will help you with the solution: you download the ...- master.zip on github, unzip it and find a "fixture" folder in it where you can find the gerber files to make the pcb. You will usually

Hi, If you are viewing this message on your mail client a link at the bottom of the message will take to the io group page and then files and wiki menu will be on the left of your screen. 73, Bill

Hi GM7, Yes I understand now surely after seeing your picture of the testfixture itself. I understand you found the problem in? the mean time. The results not being perfect can be caused by component

there's lots of real good information (+ manual) in the "Files" + "Wiki" section on the left of this screen....

Another response plot with better display settings for the x-axis.

Hi All, I've attached the response curve of the 40m filter after being corrected. It's not perfect but it now looks like the response for a 40m LPF. The initial passband has some loss but that's

Hi avvidclif, The test fixture and calibration 'tools' are homemade. You can see more detail in this picture.

Read more info on my site. 73, Gyula HA3HZ -- *** nothing is permanent only change ( http://ha3hz.hu/ ) ***

Might I ask where you got the test fixture?

In the RARS presentation on using the NanoVna it references a test fixture supposedly available thru github. It's the one with the ZIF socket for testing components. Is anyone making those for sale or

Hugen, The early FW version talks about connecting PA10 to PA12 but in your H4 schematic, it shows PA8 through R48 to PA12.? I assume R48 is not installed? Also, what about the USB_V_IN on PA4? Do I

Thanks Hugen, I added an 8M xtal with 22pf caps but it won't oscillate. (I lifted pin 5 from solder pad to connect the xtal). According to the datasheet, the F303 internal RC OSC is supposed to run at

Try this early test version, it can run on F303 without external crystal, there may be a lot of errors. https://github.com/AA6KL/NanoVNA-F303/commit/234f40245e1efbdd61bc68062492b25a5654fe5d

Sorry, slow link and little patience.

To satisfy my curiosity, I decided to simulate the three inductors in series. I find a quite good agreement. For curiosity sake I lowered the start frequency to 100 kHz, otherwise is quite the same.
